MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 13.7S 169.6E TO 17.5S 172.7E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AND SYNOPTIC DATA AT 100000Z INDICATE THAT A CIRCULATION
CENTER IS LOCATED NEAR 14.1S 170.0E. THE SYSTEM IS MOVING
SOUTHEASTWARD AT 07 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.1S
170.0E IS NOW LOCATED NEAR 14.1S 170.0E, APPROXIMATELY 480 NM WEST-
NORTHWEST OF NADI, FIJI. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY REVEALS IMPROVED, DEEP CONVECTIVE BANDING WRAPPING INTO A
WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 100216Z GPM 36
GHZ IMAGE ALSO DEPICTS A CONSOLIDATING LLCC WITH GOOD SPIRAL BANDING
WRAPPING IN FROM THE NORTH. RECENT SCATTEROMETRY DATA SHOWS 25 TO 30
KNOT WINDS ALONG THE SOUTHERN PERIPHERY WHICH IS IN LINE WITH LATEST
DVORAK INTENSITY ESTIMATES RANGING FROM T1.5-2.0. UPPER LEVEL
ANALYSIS SHOWS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH NEAR
RADIAL OUTFLOW AND LOW-MODERATE (10 TO 20 KNOTS) VERTICAL WIND
SHEAR. GLOBAL MODEL GUIDANCE IS IN GOOD AGREEMENT ON THE DEVELOPMENT
OF THE SYSTEM OVER THE NEXT 24 TO 36 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. BASED ON THE CONSOLIDATING
LLCC AND FAVORABLE UPPER LEVEL CONDITIONS, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
110500Z.//

REMARKS:
101500Z POSITION NEAR 15.7S 171.1E.
TROPICAL CYCLONE (TC) 11P (ELEVEN), LOCATED APPROXIMATELY 463 NM WEST-
NORTHWEST OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
A RAPIDLY CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
IMPROVED CONVECTIVE BANDING. A 101003Z METOP-A 89GHZ IMAGE SHOWS
DEEP CONVECTIVE BANDING WRAPPING INTO A WELL-DEFINED CENTER. OVERALL,
THERE IS GOOD CONFIDENCE IN THE CURRENT POSITION. THE CURRENT INTENSITY
IS ASSESSED AT 35 KNOTS BASED ON A PGTW DVORAK ESTIMATE OF T2.5 (35
KNOTS). TC 11P IS FORECAST TO TRACK POLEWARD ALONG THE WESTERN PERIPHERY
OF THE SUBTROPICAL RIDGE THROUGH TAU 72. AFTER TAU 72, TC 11P SHOULD
ENCOUNTER STRONG SUBTROPICAL WESTERLIES AND WILL WEAKEN SIGNIFICANTLY
WHILE TURNING EASTWARD. TC 11P IS NOT FORECAST TO UNDERGO EXTRA-TROPICAL
TRANSITION AND SHOULD SLOW AFTER TAU 96 AS A STRONG LOW-LEVEL RIDGE BUILDS
TO THE EAST AND SOUTH. DYNAMIC GUIDANCE IS IN GOOD AGREEMENT. TC 11P IS
FORECAST TO RAPIDLY INTENSIFY TO A PEAK INTENSITY OF 105 KNOTS BY TAU 60
DUE TO EXCELLENT POLEWARD OUTFLOW, WARM SST AND LOW VERTICAL WIND SHEAR (VWS).
SIGNIFICANT WEAKENING IS EXPECTED SOUTH OF 25S DUE TO COOLER SST AND STRONG
VWS. THIS WARNING SUPERSEDES AND CANCELS REF A, JOINT TYPHOON WRNCEN PEARL

REMARKS:
110300Z POSITION NEAR 16.0S 171.2E.
TROPICAL CYCLONE 11P (ELEVEN), LOCATED APPROXIMATELY 443 NM WEST-
NORTHWEST OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 04
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS DEEPENED CONVECTION WITH TIGHTENING SPIRAL BANDING.
A 102204Z AMSU-B 89 GHZ MICROWAVE IMAGE DEPICTS A SYMMETRIC LOW
LEVEL CIRCULATION CENTER WITH DEEP CONVECTION ON THE NORTHERN AND
WESTERN PERIPHERIES GIVING HIGH CONFIDENCE TO THE INITIAL POSITION.
THE INITIAL INTENSITY OF 40 KNOTS IS BASED ON DVORAK ESTIMATES FROM
MULTIPLE AGENCIES IN CLOSE AGREEMENT. TC 11P IS CURRENTLY POSITIONED
OVER WARM SEA SURFACE TEMPERATURES (31 CELSIUS) AND HAS VERY GOOD
RADIAL OUTFLOW WITH 20 KNOTS OF VERTICAL WIND SHEAR INDICATING THE
POTENTIAL FOR SIGNIFICANT DEVELOPMENT OVER THE FORECAST PERIOD,
PEAKING AT 100 KNOTS BY TAU 48. TC 11P IS FORECASTED TO TRACK
POLEWARD ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE THROUGH
TAU 72. AFTER TAU 72 TC 11P IS EXPECTED TO ROUND THE RIDGE AXIS
TAKING AN EASTERN TRACK. DYNAMIC MODEL GUIDANCE IS IN RELATIVELY
GOOD AGREEMENT GIVING HIGH CONFIDENCE TO THE FORECAST TRACK AND
INTENSITY. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 110000Z IS 12 FEET.
NEXT WARNINGS AT 111500Z AND 120300Z. REFER TO TROPICAL CYCLONE 12P

REMARKS:
111500Z POSITION NEAR 17.0S 171.6E. TROPICAL CYCLONE 11P (WINSTON),
LOCATED APPROXIMATELY 398 NM WEST OF SUVA, FIJI, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS DEEP CONVECTION SPIRALING INTO A
TIGHT, CLOUD COVERED LOW LEVEL CIRCULATION CENTER (LLCC). AN 111251Z
GPM 89 GHZ MICROWAVE IMAGE CONFIRMS THE DEEP CONVECTION WRAPPING
INTO A SMALL AND WELL DEFINED EYE FEATURE, GIVING HIGH CONFIDENCE IN
THE INITIAL POSITION. THE INITIAL INTENSITY IS BASED ON DVORAK
ESTIMATES OF T3.5 FROM MULTIPLE AGENCIES IN CLOSE AGREEMENT. AN
111035Z ASCAT PASS INDICATES 50 KNOT WINDS IN THE NORTHEAST
QUADRANT, CONFIRMING BOTH THE INITIAL INTENSITY AND THE WIND RADII.
TC WINSTON IS CURRENTLY IN A VERY FAVORABLE ENVIRONMENT WITH
EXTREMELY WARM SEA SURFACE TEMPERATURES (SSTS) EXCEEDING 31 CELSIUS,
VERY GOOD RADIAL OUTFLOW AND LIGHT TO MODERATE VERTICAL WIND SHEAR
(VWS) OF APPROXIMATELY 15-20 KNOTS. THE PRIMARY STEERING MECHANISM
FOR TC WINSTON IS THE DEEP-LAYER, SUBTROPICAL RIDGE (STR) EAST OF
THE SYSTEM. TC WINSTON IS FORECASTED TO TRACK SOUTHWARD ALONG THE
WESTERN PERIPHERY OF THIS STR THROUGH TAU 36. AFTER TAU 36, AS THE
STR BECOMES ORIENTED NORTH-SOUTH, TC WINSTON WILL ROUND THE AXIS AND
TAKE A MORE EASTWARD TRACK. BY TAU 96 THE STR HAS REPOSITIONED TO
THE NORTHWEST OF TC WINSTON INDUCING THE SYSTEM TO TRACK EQUATORWARD
ONCE AGAIN THROUGH THE END OF THE FORECAST PERIOD. OVER THE NEXT 48
HOURS, TC WINSTON WILL UNDERGO A PERIOD OF RAPID INTENSIFICATION AS
IT TRACKS IN AN AREA OF VERY HIGH SSTS WITH VWS VALUES DECREASING TO
LESS THAN 10 KNOTS. AFTER TAU 48, TC WINSTON WILL BEGIN A SLOW
WEAKENING TREND AS IT MOVES INTO A MARGINAL ENVIRONMENT WITH HIGHER
VWS VALUES AND DECREASING SSTS. DYNAMIC MODEL GUIDANCE IS IN POOR
AGREEMENT GIVING LOW CONFIDENCE TO THE FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111200Z IS 16 FEET. NEXT WARNINGS AT
120300Z AND 121500Z. REFER TO TROPICAL CYCLONE 12P (TATIANA)

REMARKS:
120300Z POSITION NEAR 18.4S 171.6E.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 388 NM WEST
OF SUVA, FIJI, HAS TRACKED SOUTHWARD AT 06 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS DEEP
CONVECTION WRAPPING INTO A TIGHT SYMMETRIC SPIRAL WITH AN EYEWALL
BEGINNING TO FORM. A 112144Z MHS 89 GHZ MICROWAVE IMAGE SHOWS DEEP
CONVECTION ON THE NORTHERN PERIPHERY OF A WELL-DEFINED LOW LEVEL
CIRCULATION CENTER GIVING HIGH CONFIDENCE TO THE INITIAL POSITION.
THE INITIAL INTENSITY IS BASED ON DVORAK ESTIMATES OF 4.0 (65 KNOTS)
FROM PGTW AND PHFO. THE UPPER-LEVEL ENVIRONMENT IS FAVORABLE WITH
RADIAL OUTFLOW AND LOW (5 TO 10 KNOT) VERTICAL WIND SHEAR WHICH
WILL SUPPORT FURTHER INTENSIFICATION. TROPICAL CYCLONE (TC) WINSTON
IS CURRENTLY TRAVELING SOUTHWARD ALONG THE WESTERN PERIPHERY OF A
SUBTROPICAL RIDGE. BY TAU 48 THE SUBTROPICAL RIDGE WILL REPOSITION
TO THE NORTH AND STEER TC WINSTON ON A NORTHEASTWARD TRACK. DYNAMIC
MODEL GUIDANCE IS IN GOOD AGREEMENT GIVING HIGH CONFIDENCE TO THE
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120000Z IS 21
FEET. NEXT WARNINGS AT 121500Z AND 130300Z. REFER TO TROPICAL

REMARKS:
121500Z POSITION NEAR 20.3S 171.6E. TROPICAL CYCLONE 11P (WINSTON), 
LOCATED APPROXIMATELY 335 NM EAST-NORTHEAST OF NOUMEA, NEW 
CALEDONIA, HAS TRACKED SOUTHWARD AT 10 KNOTS OVER THE PAST SIX HOURS.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS DEEP CONVECTION 
WRAPPING INTO AN EXTREMELY WELL DEFINED AND CLOUD-FREE EYE FEATURE, 
GIVING HIGH CONFIDENCE IN THE INITIAL POSITION. TC WINSTON HAS 
UNDERGONE A PERIOD OF RAPID INTENSIFICATION OF 40 KNOTS IN THE PAST 
12 HOURS AND THE INITIAL INTENSITY OF 105 KNOTS IS BASED ON DVORAK 
ESTIMATES BETWEEN T5.5 AND T6.0 (102 TO 115 KNOTS) FROM PGTW AND 
KNES RESPECTIVELY. TC WINSTON IS CURRENTLY TRACKING THROUGH A VERY 
FAVORABLE ENVIRONMENT, WITH STRONG RADIAL OUTFLOW, LOW (5 TO 10 
KNOT) VERTICAL WIND SHEAR (VWS) AND VERY HIGH SEA SURFACE 
TEMPERATURES (SSTS) OF 30 TO 31 DEGREES CELSIUS. THESE VERY 
FAVORABLE CONDITIONS ARE FORECAST TO CONTINUE FOR THE NEXT 12-24 
HOURS, ALLOWING TC WINSTON TO CONTINUE TO RAPIDLY INTENSIFY. THE 
SYSTEM IS CURRENTLY MOVING SOUTHWARD ALONG THE WESTERN PERIPHERY OF 
A SUBTROPICAL RIDGE. BY TAU 36 THE SUBTROPICAL RIDGE WEAKENS AND 
REPOSITIONS TO THE NORTH OF TC WINSTON, RESULTING IN A TURN TO THE 
EAST THEN NORTHEAST. AFTER TAU 72, THE SYSTEM BECOMES EMBEDDED IN A 
HIGH AMPLITUDE RIDGE/TROUGH PATTERN AND MAINTAINS A GENERAL EAST-
NORTHEAST TRACK THROUGH THE REMAINDER OF THE FORECAST PERIOD. AFTER 
THE NEAR-TERM RAPID INTENSIFICATION, TC WINSTON WILL SLOWLY WEAKEN 
AS IT MOVES OVER AREAS OF LOWER OCEAN HEAT CONTENT (OHC) AND SSTS, 
WHILE SIMULTANEOUSLY EXPERIENCING INCREASING VWS. HOWEVER, AS THE 
SYSTEM MOVES BACK TO AN EASTWARD TRACK ALONG 20 DEGREES SOUTH 
LATITUDE, OHC AND SSTS WILL AGAIN INCREASE AND VWS WILL REMAIN 
MODERATE, THEREBY ALLOWING TC WINSTON TO MAINTAIN STRENGTH THROUGH 
THE END OF THE FORECAST PERIOD. DYNAMIC MODEL GUIDANCE IS IN GOOD 
AGREEMENT GIVING HIGH CONFIDENCE TO THE FORECAST TRACK. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 121200Z IS 34 FEET. NEXT WARNINGS AT 
130300Z AND 131500Z. REFER TO TROPICAL CYCLONE 12P (TATIANA)

REMARKS:
130300Z POSITION NEAR 22.7S 172.1E.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 446 NM
SOUTHWEST OF SUVA, FIJI, HAS TRACKED SOUTHWARD AT 14 KNOTS OVER THE
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS THE
EYE REMAINS A CONSISTANT FEATURE, BUT HAS RECENTLY BECOME PARTIALLY
CLOUD FILLED, WITH DVORAK ESTIMATES FROM PGTW AND KNES REFLECTING A
SLIGHT WEAKENING TREND OVER THE PAST 12 HOURS. GIVEN THESE
OBSERVATIONS, THE CURRENT INTENSITY HAS BEEN DECREASED FROM 115
KNOTS, ON THE 121800Z OFF-CYCLE POSITION, TO 105 KNOTS. TC 11P
CONTINUES TO TRACK ALONG THE WESTERN PERIPHERY OF A DEEP LAYERED
SUBTROPICAL RIDGE (STR), ANCHORED OVER FIJI, BUT BY TAU 36, THE STR
WILL SHIFT EQUATORWARD AS A MERIDIONAL PATTERNED MID-LATITUDE TROUGH
TRACKS TO THE SOUTH OF TC WINSTON. THE TRACK WILL SHIFT TO A NEAR-
EQUATORIAL RIDGE, TAKING THE SYSTEM TO THE NORTHEAST WITH ADDITIONAL
ENHANCEMENT OF THE GRADIENT FLOW AS THE TROUGH DIGS NORTHWARD.
DECREASING SEA SURFACE TEMPERATURES WILL SLOWLY WEAKEN THE SYSTEM
FROM TAU 24 THROUGH TAU 48, BUT AS THE TRACK TAKES TC 11P
EQUATORWARD, INCREASING SSTS AND A FAVORABLE UPPER-LEVEL ENVIRONMENT
WILL PROVIDE A PERIOD OF RE-INTENSIFICATION FROM TAU 48 THROUGH TAU
120. MODEL GUIDANCE IS IN TIGHT AGREEMENT WITH THE FORECAST TRACK,
LEADING TO HIGH CONFIDENCE IN THE FORECAST. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 130000Z IS 34 FEET. NEXT WARNINGS AT 131500Z AND 140300Z.

REMARKS:
131500Z POSITION NEAR 24.5S 173.3E.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 396 NM
EAST-SOUTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTHEASTWARD
AT 10 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY REVEALS A SMALL, CLOUD-FILLED EYE FEATURE WITH
CONVECTIVE CLOUD-TOPS BEGINNING TO WARM OVER THE PAST 12 HOURS,
INDICATING A GRADUAL WEAKENING TREND IS OCCURRING. A 130735Z SSMIS
91 GHZ IMAGE DEPICTS A WELL-DEFINED MICROWAVE EYE WITH DEEP
CONVECTIVE BANDING, HOWEVER, THE STRONGEST CONVECTION IS BEGINNING
TO SHEAR TO THE EAST OF THE LOW-LEVEL CIRCULATION CENTER. UPPER-
LEVEL ANALYSIS SHOWS A MARGINALLY-FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH MODERATE (20 TO 25 KNOTS) VERTICAL WIND SHEAR (VWS)
OFFSET BY GOOD POLEWARD OUTFLOW. TC WINSTON IS CURRENTLY BEING
STEERED SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL
RIDGE (STR). AFTER TAU 24, THE STR IS FORECAST TO WEAKEN AND SHIFT
WESTWARD, WHILE AN UPPER-LEVEL TROUGH TO THE SOUTH OF THE SYSTEM
BEGINS TO DEEPEN. THIS WILL CAUSE TC 11P TO MOVE NORTHEASTWARD
THROUGH TAU 120. THE SYSTEM IS EXPECTED TO CONTINUE WEAKENING
GRADUALLY THOUGH TAU 72 AS IT ENCOUNTERS STRONG VWS WITHIN THE
TROUGH AND COLDER SSTS. HOWEVER, AFTER TAU 72, THE TROUGH BEGINS TO
FILL AND TC WINSTON IS FORECAST TO REGAIN SOME STRENGTH AS IT TRACKS
OVER MORE FAVORABLE SSTS AND LOWER VWS. DYNAMIC MODEL GUIDANCE IS IN
POOR AGREEMENT ON THE SYNOPTIC STEERING PATTERN WITH SIGNIFICANT
DIFFERENCES IN THE TIMING AND DEGREE OF THE EQUATORWARD TRACK
MOTION. THEREFORE, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 131200Z IS 32 FEET. NEXT
WARNINGS AT 140300Z AND 141500Z. REFER TO TROPICAL CYCLONE 12P

REMARKS:
140300Z POSITION NEAR 25.2S 175.3E.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 474 NM
SOUTH-SOUTHWEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS TC 11P IS MAINTAINING TIGHTLY CURVED SPIRAL BANDING
WRAPPING INTO A LOW LEVEL CIRCULATION CENTER (LLCC), HOWEVER,
CENTRAL DEEP CONVECTION IS BECOMING MORE RAGGED. THE INITIAL
POSITION IS BASED ON AGENCY FIXES AND AN EXTRAPOLATED 132151Z METOPB
MICROWAVE PARTIAL EYE WITH GOOD CONFIDENCE. THE INITIAL INTENSITY IS
ASSESSED AT 75 KNOTS, TAKING INTO ACCOUNT THE NOTED DEGRADATION OF
CONVECTION CAUSING DVORAK INTENSITY ESTIMATES TO DROP. UPPER LEVEL
ANALYSIS INDICATES THIS DEGRADATION IS DUE IN PART TO MODERATE TO
HIGH (20-30 KNOTS) VERTICAL WIND SHEAR (VWS), ALTHOUGH OUTFLOW
REMAINS ROBUST. TC 11P IS TURNING TOWARD A MORE EASTERWARD TRACK AS
THE SUB-TROPICAL STEERING RIDGE (STR) IS NOW LOCATED TO THE NORTH.
THIS STR IS EXPECTED TO RECEED EQUATORWARD OVER THE NEXT THREE DAYS
ALLOWING THE SYSTEM TO TRACK NORTHWARD AFTER TAU 24. AFTER TAU 72,
THE STR WILL BEGIN TO STRENGTHEN AND REORIENT THE TRACK BACK TO AN
EASTWARD MOTION. VWS IS EXPECTED TO REMAIN STRONG OVER THE NEXT 36-
48 HOURS, RESULTING IN ADDITIONAL WEAKENING. AFTER THIS TIME,
IMPROVING ENVIRONMENTAL CONDITIONS SHOULD ALLOW FOR A GRADUAL RE-
INTENSIFICATION TREND. DYNAMIC MODEL GUIDANCE IS IN POOR AGREEMENT
ON THE SYNOPTIC STEERING PATTERN WITH SIGNIFICANT DIFFERENCES IN THE
TIMING AND DEGREE OF THE EQUATORWARD TRACK MOTION. THEREFORE, THERE
IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 140000Z IS 29 FEET. NEXT WARNINGS AT 141500Z AND
150300Z. REFER TO TROPICAL CYCLONE 12P (TATIANA) WARNINGS (WTPS32

REMARKS:
141500Z POSITION NEAR 24.7S 178.0E.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 416 NM
SOUTH OF SUVA, FIJI, HAS TRACKED EAST-NORTHEASTWARD AT 11 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
REVEALS TC 11P HAS BECOME EMBEDDED WITHIN THE TROUGH WITH DEEP
CONVECTION BEING SHEARED TO THE EAST OF THE SYSTEM. A 141017Z AMSU-B
89 GHZ IMAGE DEPICTS TIGHTLY CURVED, SHALLOW BANDING ALONG THE
WESTERN PERIPHERY WITH DEEP CONVECTIVE BANDING ALONG THE EASTERN
PERIPHERY OF THE LOW-LEVEL CIRCULATION CENTER. THE INITIAL POSITION
IS BASED UPON A 141018Z ASCAT IMAGE WITH GOOD CONFIDENCE. THE
INITIAL INTENSITY IS ASSESSED AT 65 KNOTS BASED UPON THE RECENT
SCATTEROMETRY DATA, AND MULTI-AGENCY DVORAK INTENSITY VALUES RANGING
FROM 55 TO 65 KNOTS. UPPER LEVEL ANALYSIS SHOWS A MARGINAL
ENVIRONMENT FOR DEVELOPMENT WITH GOOD POLEWARD OUTFLOW BEING OFFSET
BY MODERATE-STRONG (25 TO 30 KNOTS) VERTICAL WIND SHEAR (VWS). TC
11P IS FORECAST TO CONTINUE TRACKING NORTHEASTWARD ALONG THE
SOUTHEAST PERIPHERY OF THE STEERING RIDGE. A WEAKNESS IN THE RIDGE
IS FORECAST TO FORM BETWEEN TAU 48 THROUGH TAU 96, CAUSING THE
SYSTEM TO SLOW IN FORWARD SPEED, AND THEN BECOME QUASI-STATIONARY
AFTER TAU 96, AS A SECONDARY RIDGE BUILDS IN FROM THE SOUTHWEST. TC
WINSTON IS FORECAST TO WEAKEN SLIGHTLY OVER THE NEXT 24 HOURS AS IT
CONTINUES TO TRACK THROUGH AN ENVIRONMENT WITH STRONG VWS. HOWEVER,
AFTER TAU 48, GRADUAL RE-INTENSIFICATION OF THE SYSTEM IS FORECAST
AS IT TRACKS OVER AN AREA WITH LOWER VWS AND WARMER SSTS. DYNAMIC
MODEL GUIDANCE IS IN POOR AGREEMENT ON THE SYNOPTIC STEERING PATTERN
WITH SIGNIFICANT DIFFERENCES. THEREFORE, THERE IS LOW CONFIDENCE IN
THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141200Z
IS 23 FEET. NEXT WARNINGS AT 150300Z AND 151500Z.//

REMARKS:
150300Z POSITION NEAR 22.6S 179.9E.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 302 NM
SOUTH-SOUTHEAST OF SUVA, FIJI, HAS TRACKED NORTHEASTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THAT TC 11P HAS MAINTAINED TIGHTLY CURVED SPIRAL
BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER (LLCC)
WHILE DEEP CONVECTION HAS SHALLOWED SLIGHTLY. THE INITIAL POSITION
IS BASED UPON AGENCY FIXES AND A 142044Z PARTIAL ASCAT PASS WITH
GOOD CONFIDENCE. THE INITIAL INTENSITY IS ASSESSED AT 60 KNOTS BASED
UPON THE SCATTEROMETRY DATA WHICH HAD A SWATH OF 65 KNOT WINDS ALONG
THE SOUTHERN SEMI-CIRCLE, AND TAKING INTO ACCOUNT MORE RECENT AGENCY
DVORAK CURRENT INTENSITY ESTIMATES OF 55 KNOTS. ENVIRONMENTAL
CONDITIONS REMAIN MARGINAL AS TC 11P REMAINS EMBEDDED WITHIN A
TROUGH WITH MODERATE TO STRONG VERTICAL WIND SHEAR (VWS), HOWEVER
THE EASTWARD OUTFLOW CHANNEL REMAINS ROBUST AND SSTS ARE GRADUALLY
RISING AS THE SYSTEM TRACKS EQUATORWARD. WINSTON IS FORECAST TO
CONTINUE TRACKING GENERALLY NORTHEASTWARD OVER THE NEXT TWO DAYS AS
RIDGING BUILDS IN BEHIND THE SYSTEM AND PROVIDES A WEAK STEERING
FLOW. BY DAY TWO, TC 11P WILL SLOW AS MUCH MORE PRONOUNCED SUB-
TROPICAL RIDGING FORMS AHEAD OF IT, RESULTING IN A SLOW TURN OR LOOP
BACK TO THE WEST STARTING AROUND DAY THREE. WINSTON IS FORECAST TO
WEAKEN SLIGHTLY OVER THE NEXT 24 HOURS AS IT CONTINUES TO TRACK
THROUGH AN ENVIRONMENT WITH STRONG VWS. AS THE CURRENT UPPER LEVEL
TROUGHING MOVES OFF, GRADUAL RE-INTENSIFICATION OF THE SYSTEM IS
FORECAST AS IT TRACKS OVER AN AREA WITH LOWER VWS AND WARMER SSTS.
THIS INTENSIFICATION MAY BECOME MORE PRONOUNCED AS THE FOREWARD
MOTION STALLS DURING THE TURN. DYNAMIC MODEL GUIDANCE IS IN POOR
AGREEMENT ON THE SYNOPTIC STEERING PATTERN WITH SIGNIFICANT
DIFFERENCES. THEREFORE, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150000Z IS 21 FEET. NEXT
WARNINGS AT 151500Z AND 160300Z.

REMARKS:
151500Z POSITION NEAR 20.3S 177.7W.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 248 NM
SOUTHEAST OF SUVA, FIJI, HAS TRACKED NORTHEASTWARD AT 18 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY REVEALS TC 11P REMAINS EMBEDDED WITHIN THE TROUGH, HOWEVER
DEEP CONVECTIVE COVERAGE HAS BEGUN TO EXPAND AND CLOUD-TOPS HAVE
COOLED OVER THE PAST 6-HOURS. A 151051Z GPM 36 GHZ IMAGE DEPICTS A
WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH TIGHTLY CURVED
BANDING WRAPPING INTO THE SYSTEM. THE INITIAL POSITION IS BASED UPON
A 150958Z ASCAT AMBIGUITY ANALYSIS WITH GOOD CONFIDENCE. THE INITIAL
INTENSITY IS ASSESSED AT 50 KNOTS BASED UPON THE RECENT
SCATTEROMETRY DATA. UPPER LEVEL ANALYSIS SHOWS A MARGINALLY-
FAVORABLY ENVIRONMENT FOR DEVELOPMENT WITH GOOD OUTFLOW OFFSET BY
MODERATE TO STRONG (20 TO 30 KNOTS) VERTICAL WIND SHEAR (VWS). TC
WINSTON IS FORECAST TO CONTINUE TRACKING NORTHEASTWARD ALONG THE
SOUTHEAST PERIPHERY OF THE STEERING RIDGE. A WEAKNESS IN THE RIDGE
IS FORECAST TO FORM BETWEEN TAU 36 THROUGH TAU 72, CAUSING THE
SYSTEM TO SLOW IN FORWARD SPEED, AND THEN BECOME QUASI-STATIONARY
AFTER TAU 36, AS A SECONDARY RIDGE BUILDS IN FROM THE SOUTHWEST.
AFTER TAU 72, TC 11P WILL BEGIN TO ACCELERATE WESTWARD AS THE RIDGE
TO THE EAST STRENGTHENS AND THE RIDGE TO THE SOUTHWEST MOVES
WESTWARD. TC WINSTON IS FORECAST TO GRADUALLY REGAIN INTENSITY
DURING THE FORECAST PERIOD AS IT TRACKS OVER WARMER (29-30C) SSTS
AND THROUGH A REGION OF DECREASING VWS. DYNAMIC MODEL GUIDANCE IS IN
FAIR AGREEMENT THROUGH TAU 48, HOWEVER, SOLUTIONS BEGIN TO DIVERGE
AFTER TAU 48 DUE TO HIGH UNCERTAINTY WITH THE OVERALL SYNOPTIC
STEERING PATTERN. THEREFORE, THERE IS LOW CONFIDENCE IN THE JTWC
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151200Z IS 21
FEET. NEXT WARNINGS AT 160300Z AND 161500Z.//

REMARKS:
160300Z POSITION NEAR 18.9S 175.0W.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 353 NM
EAST-SOUTHEAST OF SUVA, FIJI, HAS TRACKED EAST-NORTHEASTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY INDICATES THAT DIURNAL BURST OF DEEP CONVECTION HAS WEAKENED
OVER THE PAST SIX HOURS WITH SHALLOW CONVECTION NOW BANDING INTO A
WEAK, CLOUD-COVERED LOW-LEVEL CIRCULATION CENTER (LLCC). A 152108Z
89 GHZ AMSU-B MICROWAVE IMAGE DEPICTS TIGHTLY CURVED BANDING
WRAPPING INTO A BROAD, RAGGED MICROWAVE EYE FEATURE SUPPORTING THE
INITIAL POSITION WITH GOOD CONFIDENCE. THE INITIAL INTENSITY IS
ASSESSED AT 45 KNOTS BASED UPON MULTI-AGENCY DVORAK ESTIMATES
BETWEEN T3.0 AND T3.5. TC WINSTON REMAINS IN A MARGINAL ENVIRONMENT,
WITH HIGH SEA SURFACE TEMPERATURES (SSTS) ABOVE 31 DEGREES CELSIUS,
BEING LIMITED BY A SINGLE OUTFLOW CHANNEL AROUND THE BASE OF AN
UPPER-LEVEL TROUGH TO THE SOUTHEAST AND MODERATE (20 TO 25 KNOTS)
VERTICAL WIND SHEAR (VWS). THIS WARNING CONTAINS A SIGNIFICANT
CHANGE IN THE FORECAST PHILOSOPHY. TC WINSTON IS FORECAST TO
CONTINUE TRACKING EAST-NORTHEASTWARD UNDER THE COMBINED INFLUENCE OF
DEEP-LAYER SUBTROPICAL RIDGES (STR) TO THE WEST AND NORTH THROUGH
TAU 36. AFTER TAU 36, THE WESTERN STR WILL BUILD AND BEGIN TO MOVE
WESTWARD WHILE THE EASTERN STR WILL BUILD WHILE REMAINING NEARLY
QUASI-STATIONARY, CAUSING TC WINSTON TO SLOW ITS FORWARD SPEED
SIGNIFICANTLY, BECOMING QUASI-STATIONARY BY TAU 72. AFTER TAU 72,
AND CONTRARY TO THE PREVIOUS FORECAST, THE SYSTEM WILL BEGIN A SLOW
TURN TO THE SOUTHEAST TOWARDS AN INDUCED WEAKNESS IN THE RIDGE
PATTERN AS THE RIDGE TO THE WEST WEAKENS AND MOVES FURTHER WESTWARD
AND THE RIDGE TO THE EAST REORIENTS TO THE NORTH. TC WINSTON IS
FORECAST TO GRADUALLY RE-INTENSIFY DURING THE FORECAST PERIOD AS IT
TRACKS OVER WARMER (29-30C) SSTS AND THROUGH A REGION OF DECREASING
VWS. A SLIGHT WEAKENING IS FORECAST BY TAU 120 AS THE SYSTEM BECOMES
QUASI-STATIONARY AND INCREASED UPWELLING OF COOLER WATER OCCURS.
DYNAMIC MODEL GUIDANCE IS IN POOR AGREEMENT AFTER TAU 36, WITH A
BIFURCATION INTO TWO DISTINCT SOLUTIONS DUE TO HIGH UNCERTAINTY WITH
THE OVERALL SYNOPTIC STEERING PATTERN, LEADING TO LOW CONFIDENCE IN
THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 160000Z
IS 22 FEET. NEXT WARNINGS AT 161500Z AND 170300Z.//

VERTICAL WIND SHEAR. A STRONG WESTERLY OUTFLOW CHANNEL IS ALSO
SUPPORTING FURTHER INTENSIFICATION, TAPPING INTO A LONGWAVE TROUGH
POSITIONED TO THE SOUTHEAST. A SUBTROPICAL RIDGE TO THE NORTHWEST IS
STEERING THE CYCLONE ALONG AN EASTWARD TRACK. DYNAMIC MODEL GUIDANCE
SUGGESTS THAT BY TAU 36 THE RIDGE WILL WEAKEN SIGNIFICANTLY
PROVIDING A VERY WEAK STEERING ENVIRONMENT, AND TC WINSTON IS
EXPECTED TO BECOME QUASI-STATIONARY AND REMAIN IN A WEAK STEERING
ENVIRONMENT UNTIL THE END OF THE FORECAST PERIOD. OCEAN HEAT CONTENT
IS RELATIVELY HIGH WHICH WILL SUPPORT INTENSIFICATION, AND TC
WINSTON IS EXPECTED TO REACH 95 KNOTS BY TAU 72. DUE TO THE WEAK AND
COMPETING STEERING ENVIRONMENT, MODEL GUIDANCE IS IN DISAGREEMENT AS
THE CYCLONE BECOMES QUASI-STATIONARY. THIS PROVIDES LOW CONFIDENCE
TO THE JTWC FORECAST TRACK BEYOND TAU 36. DUE TO THE PROXIMITY OF TC
WINSTON TO PAGO PAGO, AMERICAN SAMOA, WARNINGS WILL NOW BE ISSUED
EVERY SIX HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 160600Z IS 24
FEET. NEXT WARNINGS AT 161500Z, 162100Z, 170300Z AND 170900Z.//

REMARKS:
161500Z POSITION NEAR 17.8S 173.2W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 273 NM
SOUTHWEST OF PAGO PAGO, HAS TRACKED NORTHEASTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS CONVECTIVE BANDING WRAPPING INTO AN AREA OF
INCREASED CENTRAL CONVECTION WITH A WEAKLY DEFINED 23NM EYE, GIVING
VERY HIGH CONFIDENCE TO THE INITIAL POSITION. A 160937Z SSMIS 89 GHZ
MICROWAVE IMAGE ALSO SHOWS INCREASED CENTRAL CONVECTION SURROUNDING
THE MICROWAVE EYE. THE INITIAL INTENSITY IS 65 KNOTS AND BASED ON
DVORAK ESTIMATES FROM PGTW REPORTING T4.0 (65 KNOTS). TC WINSTON IS
CURRENTLY POSITIONED IN A GOOD ENVIRONMENT FOR INTENSIFICATION WITH
FAVORABLE SEA SURFACE TEMPERATURES (30 CELSIUS) AND LOW (10 TO 15
KNOTS) VERTICAL WIND SHEAR. A STRONG WESTERLY OUTFLOW CHANNEL IS
ALSO SUPPORTING THE CURRENT INTENSIFICATION, TAPPING INTO A LONGWAVE
TROUGH POSITIONED TO THE SOUTHEAST. A SUBTROPICAL RIDGE TO THE
NORTHWEST IS STEERING THE CYCLONE ALONG AN EASTWARD TRACK. DYNAMIC
MODEL GUIDANCE SUGGESTS THAT BY TAU 24 THE RIDGE WILL WEAKEN
SIGNIFICANTLY PROVIDING A VERY WEAK STEERING ENVIRONMENT, AND
TC WINSTON IS EXPECTED TO BECOME QUASI-STATIONARY AND REMAIN IN A
WEAK STEERING ENVIRONMENT UNTIL APPROXIMATELY TAU 96 WHEN AN EAST-
WEST RIDGE BEGINS TO BUILD TO THE SOUTH SENDING TC WINSTON ON A
WESTWARD TRACK. ENVIRONMENTAL CONDITIONS WILL REMAIN FAVORABLE WHICH
WILL SUPPORT INTENSIFICATION, AND TC WINSTON IS EXPECTED TO REACH
100 KNOTS BY TAU 48. DUE TO THE WEAK AND COMPETING STEERING
ENVIRONMENT, MODEL GUIDANCE IS IN DISAGREEMENT AS THE CYCLONE
BECOMES QUASI-STATIONARY; HOWEVER HAS IMPROVED WITH THE EXTENDED
FORECAST TURN TO THE WEST. THIS PROVIDES LOW CONFIDENCE TO THE JTWC
FORECAST TRACK BEYOND TAU 24. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
161200Z IS 24 FEET. NEXT WARNINGS AT 162100Z, 170300Z, 170900Z AND

INTO A CENTRAL DENSE OVERCAST. A 161812Z SSMIS 91 GHZ MICROWAVE
IMAGE DEPICTS CENTRAL CONVECTION COMPLETELY SURROUNDING A WELL-
DEFINED MICROWAVE EYE FEATURE, GIVING HIGH CONFIDENCE IN THE INITIAL
POSITION. THE INITIAL INTENSITY IS ASSESSED AT 75 KNOTS BASED ON
DVORAK ESTIMATES FROM PGTW REPORTING T4.5. ENVIRONMENTAL ANALYSIS
INDICATES THAT TC WINSTON IS CURRENTLY TRACKING IN AN AREA THAT IS
ADVANTAGEOUS FOR FURTHER INTENSIFICATION WITH FAVORABLE SEA SURFACE
TEMPERATURES (30 CELSIUS), LOW TO MODERATE (15 TO 20 KNOTS) VERTICAL
WIND SHEAR AND A STRONG POLEWARD OUTFLOW CHANNEL. THE PRIMARY
STEERING MECHANISM IS A DEEP-LAYER NEAR-EQUATORIAL RIDGE TO THE
NORTH, WHICH WILL CONTINUE TO STEER TC WINSTON ON ITS CURRENT EAST-
NORTHEASTWARD TRACK THROUGH TAU 24. BETWEEN TAUS 24 AND 48, AS THE
WESTERN RIDGE BUILDS TO THE SOUTH OF THE TC, A DEEP-LAYER
SUBTROPICAL RIDGE (STR) WILL BUILD IN TO THE EAST, CAUSING TC
WINSTON TO RAPIDLY SLOW ITS FORWARD MOVEMENT, ULTIMATELY BECOMING
QUASI-STATIONARY BY TAU 48. AFTER TAU 48, UNDER THE COMBINED
INFLUENCE OF THE TWO AFOREMENTIONED RIDGES, TC WINSTON WILL
TRANSLATE TO A WEST-SOUTHWESTWARD TRACK THROUGH TAU 96.  AFTERWARDS,
THE TRACK WILL BECOME MORE SOUTHWARD, TRACKING TOWARDS A WEAKNESS IN
THE STR AHEAD OF AN ADVANCING MID-LATITUDE TROUGH. ENVIRONMENTAL
CONDITIONS WILL REMAIN FAVORABLE FOR INTENSIFICATION, AND TC WINSTON
IS EXPECTED TO REACH 110 KNOTS BY TAU 48. DUE TO THE UNCERTAINTY IN
THE OVERALL SYNOPTIC ENVIRONMENT, DYNAMIC MODEL GUIDANCE IS IN
DISAGREEMENT BEYOND TAU 24, AS THE CYCLONE BECOMES QUASI-STATIONARY,
BUT HAS COME INTO BETTER AGREEMENT OVER THE PAST 12 HOURS IN
FORECASTING THE TURN TO THE WEST. DUE TO THIS UNCERTAINTY, THERE IS
LOW CONFIDENCE TO THE JTWC FORECAST TRACK BEYOND TAU 24. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 161800Z IS 28 FEET. NEXT WARNINGS AT
170900Z AND 172100Z.//

REMARKS:
170300Z POSITION NEAR 17.5S 171.5W.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 145 NM
NORTHWEST OF NIUE, HAS TRACKED EASTWARD AT 06 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS DEEP
CONVECTION CONTINUING TO IMPROVE WITH COLD CONVECTIVE TOPS WRAPPING
INTO A VERY COMPACT EYE THAT HAS DEVELOPED OVER THE PAST TWO HOURS.
A 162321Z GPM 91 GHZ MICROWAVE PASS INDICATES THAT DEEP CONVECTION
COMPLETELY SURROUNDS A DISTINCT AND COMPACT MICROWAVE EYE FEATURE,
LEADING TO HIGH CONFIDENCE IN THE INITIAL POSITION. THE INITIAL
INTENSITY IS ASSESSED AT 90 KNOTS BASED ON DVORAK ESTIMATES OF T5.0
FROM ALL AGENCIES. ANALYSIS INDICATES THAT THE OVERALL ENVIRONMENT
SURROUNDING TC WINSTON REMAINS FAVORABLE. VERTICAL WIND SHEAR (VWS)
VALUES HAVE DECREASED OVER THE PAST SIX HOURS AND ARE NOW IN THE LOW
RANGE (10 TO 15 KNOTS). SEA SURFACE TEMPERATURE REMAINS HIGH (30
CELSIUS) AND THERE ARE INDICATIONS OF THE DEVELOPMENT OF AN
EQUATORWARD OUTFLOW CHANNEL IN ADDITION TO THE ESTABLISHED EASTWARD
CHANNEL. THE PRIMARY STEERING MECHANISM REMAINS THE DEEP-LAYER NEAR-
EQUATORIAL RIDGE TO THE NORTH, WHICH WILL CONTINUE TO STEER TC
WINSTON ON ITS CURRENT EASTWARD TRACK FOR THE NEXT 12 HOURS, ALBEIT
AT A MUCH SLOWER PACE, TC WINSTON HAVING ALREADY SLOWED
SIGNIFICANTLY SINCE THE PREVIOUS WARNING. AS A RIDGE BUILDS TO THE
SOUTH OF THE TC, A DEEP-LAYER SUBTROPICAL RIDGE (STR) WILL
SIMULTANEOUSLY BUILD IN FROM THE EAST, CAUSING TC WINSTON TO BECOME
QUASI-STATIONARY BY TAU 24. AFTER TAU 36, UNDER THE COMBINED
INFLUENCE OF THE TWO AFOREMENTIONED RIDGES, TC WINSTON WILL
TRANSLATE TO A WEST-SOUTHWESTWARD TRACK AND ACCELERATE THROUGH TAU
72. THROUGH THE REMAINING PORTION OF THE FORECAST PERIOD, TC WINSTON
WILL TRANSITION TO A MORE SOUTHWARD TRACK TOWARDS A WEAKNESS IN THE
STR AHEAD OF AN ADVANCING MID-LATITUDE TROUGH. ENVIRONMENTAL
CONDITIONS ARE FAVORABLE FOR A PERIOD OF RAPID INTENSIFICATION OVER
THE NEXT 24 HOURS, PEAK INTENSITY REACHING 125 KNOTS BY TAU 36.
THEREAFTER THE SYNOPTIC ENVIRONMENT REMAINS SUPPORTIVE OF
MAINTAINING TC WINSTON AS AN INTENSE SYSTEM THROUGH THE END OF THE
FORECAST PERIOD. DYNAMIC MODEL GUIDANCE HAS COME INTO BETTER
AGREEMENT BUT STILL DEPICTS MODERATE UNCERTAINTY AFTER TAU 48. DUE
TO THIS UNCERTAINTY, THERE IS LOW CONFIDENCE TO THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 170000Z IS 32 FEET. NEXT
WARNINGS AT 170900Z, 171500Z, 172100Z AND 180300Z.//

REMARKS:
170900Z POSITION NEAR 17.5S 171.1W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 121 NM
NORTHWEST OF NIUE, HAS TRACKED EASTWARD AT 04 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS DEEP
BANDS OF CONVECTION WITH DENSE OVERCAST OBSCURING AN EYE OBSERVED
PREVIOUSLY. A 170548Z SSMIS 91 GHZ MICROWAVE IMAGE SHOWS A SMALL
WELL-DEFINED LOW LEVEL CIRCULATION CENTER, GIVING HIGH CONFIDENCE TO
THE INITIAL POSITION, WITH NO NOTICEABLE IMPROVEMENT IN THE STRENGTH
OR ORGANIZATION IN THE CONVECTIVE STRUCTURE IN THE LAST SIX HOURS.
THE INITIAL INTENSITY IS ASSESSED AT 90 KNOTS AND IS BASED ON DVORAK
ESTIMATES FROM PGTW AND KNES REPORTING CURRENT INTENSITIES OF T5.0
(90 KNOTS). RECENT ANIMATED CIMSS MIMIC-TPW IMAGERY SHOWS A THIN
BAND OF DRY AIR BEGINNING TO BE ENTRAINED INTO TC WINSTON, WHICH
EXPLAINS THE LACK OF INTENSIFICATION OBSERVED IN THE LAST SIX HOURS
AND WILL HAMPER THE RATE OF INTENSIFICATION IN THE FUTURE. HOWEVER,
SEA SURFACE TEMPERATURES ARE HIGH (30 CELSIUS), AND FAVORABLE UPPER-
LEVEL CONDITIONS WILL PERSIST THROUGHOUT THE FORECAST WITH LOW (10
TO 15 KNOTS) VERTICAL WIND SHEAR AND SUFFICIENT DIVERGENCE ALOFT. TC
WINSTON IS EXPECTED TO INTENSIFY TO 115 KNOTS BY TAU 36. TC WINSTON
IS CURRENTLY ENTERING A WEAK STEERING ENVIRONMENT AND WILL REMAIN
QUASI-STATIONARY FOR THE NEXT 24 TO 36 HOURS BEFORE A RIDGE
EXTENSION BUILDS SOUTH AND STEERS WINSTON ALONG A WESTWARD TRACK. BY
TAU 48 A TROUGH TO THE WEST WILL WEAKEN THE WESTERN RIDGE AND ALLOW
A SECONDARY RIDGE POSITIONED TO THE NORTHEAST OF THE CYCLONE TO
ASSUME STEERING, TURNING TC WINSTON TO THE SOUTHEAST BY TAU 72.
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT ON THE GENERAL TRACK,
BUT MODELS VARY GREATLY IN THE TIMING OF THE TURNS, GIVING LOW
CONFIDENCE TO THE FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
170600Z IS 28 FEET. NEXT WARNINGS AT 171500Z, 172100Z, 180300Z AND
180900Z.

REMARKS:
171500Z POSITION NEAR 17.5S 171.0W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 115 NM
NORTH-NORTHWEST OF NIUE, HAS TRACKED EASTWARD AT 02 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS A BROAD AREA OF CENTRAL CONVECTION WITH VERY SHALLOW BANDING
WRAPPING INTO THE CIRCULATION THAT HAS REMAINED MOSTLY UNCHANGED.
THE OBSCURED LOW LEVEL CIRCULATION CENTER PROVIDES LOW CONFIDENCE
IN THE CURRENT POSITION. THE INITIAL INTENSITY IS ASSESSED AT 90
KNOTS AND IS BASED ON DVORAK ESTIMATES FROM PGTW AND KNES REPORTING
CURRENT INTENSITIES OF T5.0 (90 KNOTS). RECENT ANIMATED CIMSS MIMIC-
TPW IMAGERY SHOWS A THIN BAND OF DRY AIR BEGINNING TO BE ENTRAINED
INTO TC WINSTON, RESPONSIBLE FOR THE LACK OF INTENSIFICATION
OBSERVED IN THE LAST SIX HOURS AND WILL HAMPER THE RATE OF
INTENSIFICATION GOING FORWARD. HOWEVER, SEA SURFACE TEMPERATURES ARE
HIGH (30 CELSIUS), AND FAVORABLE UPPER-LEVEL CONDITIONS WILL PERSIST
THROUGHOUT THE FORECAST WITH LOW (10 TO 15 KNOTS) VERTICAL WIND
SHEAR AND SUFFICIENT DIVERGENCE ALOFT. TC WINSTON IS FORECAST TO
INTENSIFY TO 115 KNOTS BY TAU 48. TC WINSTON IS CURRENTLY ENTERING A
WEAK STEERING ENVIRONMENT AND WILL REMAIN QUASI-STATIONARY FOR THE

REMARKS:
172100Z POSITION NEAR 17.2S 170.8W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 125 NM
NORTH-NORTHWEST OF NIUE, HAS TRACKED EASTWARD AT 02 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS DEEPENED CENTRAL CONVECTION ASSOCIATED WITH A CONSOLIDATING
LOW-LEVEL CIRCULATION CENTER. A 171759Z SSMIS MICROWAVE IMAGE ALSO
REVEALS TIGHTLY-CURVED BANDING WRAPPING INTO AN APPARENT MICROWAVE
EYE, SUPPORTING THE HIGH CONFIDENCE IN THE CURRENT POSITION. THE
INITIAL INTENSITY OF 95 KNOTS IS BASED ON AN OVERALL ASSESSMENT OF
DVORAK INTENSITY ESTIMATES FROM ALL REPORTING AGENCIES AND THE
IMPROVED STRUCTURE. UPPER-LEVEL ANALYSIS INDICATES WINSTON IS
LOCATED IN A FAVORABLE ENVIRONMENT WITH LOW (10 TO 15 KNOT) VERTICAL
WIND SHEAR AND GOOD POLEWARD OUTFLOW. ADDITIONALLY, SEA SURFACE
TEMPERATURES (30 DEGREES CELSIUS) ARE CONDUCIVE FOR FURTHER
DEVELOPMENT. FAVORABLE CONDITIONS ARE FORECAST TO PERSIST, ALLOWING
STEADY INTENSIFICATION OVER THE NEXT 36 HOURS, LEADING TO A PEAK
INTENSITY OF 115 KNOTS. AFTER TAU 48, UPPER-LEVEL CONDITIONS WILL
SLOWLY DEGRADE, LEADING TO ITS WEAKENING TREND. SLOW AND/OR QUASI-
STATIONARY MOVEMENT IS EXPECTED AS TC WINSTON REMAINS IN A WEAK
STEERING ENVIRONMENT FOR THE NEXT 12 TO 18 HOURS. DYNAMIC MODEL
GUIDANCE IS OVERALL IN FAIR AGREEMENT ON THE GENERAL TRACK IN THE
NEAR TERM, BUT VARIES GREATLY IN THE TIMING OF THE TURN. IN THE
EXTENDED TAUS, THERE IS SIGNIFICANT SPREAD AMONG AVAILABLE TRACKERS.
FOR THIS REASON, THE JTWC TRACK CONFIDENCE LEVEL REMAINS LOW.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171800Z IS 28 FEET. NEXT WARNINGS
AT 180300Z, 180900Z, 181500Z AND 182100Z.//

REMARKS:
180900Z POSITION NEAR 17.1S 171.9W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 154 NM
NORTHWEST OF NIUE, HAS TRACKED WESTWARD AT 05 KNOTS OVER THE PAST
SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY REVEALS A
BROADENING, CLOUD-FILLED EYE FEATURE WITH TIGHTLY CURVED, CONVECTIVE
BANDING WRAPPING INTO THE SYSTEM. A 180634Z SSMIS 91 GHZ IMAGE
DEPICTS A LARGE MICROWAVE EYE WITH THE DEEPEST CONVECTION ALONG THE
EASTERN PERIPHERY. THE INITIAL INTENSITY IS ASSESSED AT 95 KNOTS
BASED UPON DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T5.0-5.5
(90 TO 102 KNOTS) FROM MULTIPLE AGENCIES. UPPER LEVEL ANALYSIS
INDICATES A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH A GOOD
POLEWARD OUTFLOW CHANNEL AND WEAK (10 TO 15 KNOTS) VERTICAL WIND
SHEAR (VWS). TC WINSTON HAS BEGUN TO PICK UP FORWARD SPEED AFTER
BEING QUASI-STATIONARY OVER THE PAST 24 HOURS, AS IT TRACKS ALONG
THE NORTHERN PERIPHERY OF A BUILDING RIDGE TO THE SOUTH. AFTER TAU
72, THE SYSTEM WILL BEGIN TO RE-CURVE TO THE SOUTH AND THEN
SOUTHEAST BY TAU 120, AS THE RIDGE RE-ORIENTS POLEWARD AND A TROUGH
APPROACHES FROM THE WEST. TC 11P IS FORECAST TO STRENGTHEN SLIGHTLY
FROM TAU 12 TO 24, AS VWS REMAINS WEAK, AND SSTS REMAIN FAVORABLE.
AFTER TAU 24, THE SYSTEM WILL WEAKEN GRADUALLY AS IT TRACKS OVER
COLDER SSTS. TC WINSTON WILL BEGIN TO WEAKEN MORE RAPIDLY AFTER TAU
48 AS IT TRACKS OVER AN AREA OF UNFAVORABLE VWS. DYNAMIC MODEL
GUIDANCE IS IN FAIR AGREEMENT IN THE NEAR TERM, AND THEN BEGINS TO
DIVERGE IN LATER TAUS, DUE TO HIGH UNCERTAINTY WITH THE OVERALL
SYNOPTIC STEERING PATTERN. THEREFORE, THERE IS LOW CONFIDENCE IN THE
JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180600Z IS
28 FEET. NEXT WARNINGS AT 181500Z AND 192100Z.//

REMARKS:
182100Z POSITION NEAR 17.5S 173.7W.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 219 NM
WEST-NORTHWEST OF NIUE, HAS TRACKED WEST-SOUTHWESTWARD AT 10
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY AND A 181723Z AMSU-B MICROWAVE IMAGE DEPICT A SYMMETRIC
SIGNATURE WITH AN APPARENT EYE FEATURE, SUPPORTING THE HIGH
CONFIDENCE IN THE CURRENT POSITION. THE INITIAL INTENSITY OF 105
KNOTS IS HEDGED SLIGHTLY HIGHER THAN CORRESPONDING DVORAK CURRENT
INTENSITY ESTIMATES OF T5.5 (102 KNOTS) FROM ALL REPORTING AGENCIES.
UPPER-LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH A GOOD POLEWARD OUTFLOW CHANNEL AND WEAK (5 TO 10
KNOT) VERTICAL WIND SHEAR (VWS). WINSTON IS CURRENTLY TRACKING
ALONG THE NORTHERN PERIPHERY OF A BUILDING RIDGE TO THE SOUTH. BY
TAU 72, THE SYSTEM WILL BEGIN TO TURN TO THE SOUTHEAST AND WILL
REMAIN ON A SOUTHEASTWARD TRAJECTORY THROUGH THE REMAINDER OF THE
FORECAST PERIOD. TC 11P IS FORECAST TO SLIGHTLY INTENSIFY AS
FAVORABLE CONDITIONS PERSIST. AFTER TAU 24, THE SYSTEM WILL WEAKEN
GRADUALLY AS IT TRACKS OVER COLDER SSTS. TC WINSTON WILL BEGIN TO
WEAKEN MORE RAPIDLY BY TAU 72 AS IT MOVES OVER AN AREA WITH
INCREASING VWS. DYNAMIC MODEL GUIDANCE HAS COME INTO BETTER
AGREEMENT WITH THE OVERALL SYNOPTIC STEERING PATTERN. THEREFORE,
THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 181800Z IS 30 FEET. NEXT WARNINGS AT
190900Z AND 192100Z.//

REMARKS:
190900Z POSITION NEAR 17.5S 176.4W.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 330 NM
EAST OF SUVA, FIJI, HAS TRACKED WESTWARD AT 12 KNOTS OVER THE PAST
SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A
190405Z SSMIS 91 GHZ IMAGE REVEAL A SYMMETRIC EYEWALL SURROUNDING A
15 NM EYE, WITH CLOUD-TOP COOLING OBSERVED OVER THE PAST 6-HOURS.
THE INITIAL INTENSITY IS ASSESSED AT 125 KNOTS BASED UPON DVORAK
CURRENT INTENSITY ESTIMATES OF T6.5 (127 KNOTS) FROM MULTIPLE
AGENCIES. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH DUAL CHANNEL OUTFLOW AND WEAK (5 TO 10 KNOTS)
VERTICAL WIND SHEAR (VWS). TC 11P IS CURRENTLY TRACKING ALONG THE
NORTHERN PERIPHERY OF A BUILDING RIDGE TO THE SOUTH. AFTER TAU 48,
THE SYSTEM WILL RECURVE SHARPLY SOUTHWARD, AS THE RIDGE RE-ORIENTS
POLEWARD AND A TROUGH APPROACHES FROM THE WEST. TC 11P IS FORECAST
TO STRENGTHEN SLIGHTLY OVER THE NEXT 24 HOURS, AS VWS REMAINS WEAK,
SSTS REMAIN ABOVE 30C, AND UPPER LEVEL OUTFLOW REMAINS FAVORABLE.
THE SYSTEM IS CURRENTLY FORECAST TO MAKE LANDFALL ALONG THE EAST
COAST OF FIJI AROUND TAU 36, WITH AN INTENSITY BETWEEN 130 AND 135
KNOTS. AFTER TAU 48, THE SYSTEM WILL BEGIN TO WEAKEN DUE TO LAND
INTERACTIONS. AFTER TAU 72, TC WINSTON IS FORECAST TO WEAKEN RAPIDLY
AS IT TRACKS OVER COLDER SSTS, AND ENCOUNTERS HIGHER VWS AS IT
BECOMES EMBEDDED WITHIN THE TROUGH. DYNAMIC MODEL GUIDANCE CONTINUES
TO CONSOLIDATE ON THE OVERALL SYNOPTIC STEERING PATTERN. THEREFORE,
THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 190600Z IS 35 FEET. NEXT WARNINGS AT
191500Z, 192100Z, 200300Z AND 200900Z.//

222100Z POSITION NEAR 19.0S 172.8E.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 332 NM
WEST OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 06 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS TIGHTLY CURVED BANDING WRAPPING INTO A RAGGED 20 NM EYE. A
221620Z SSMIS 91 GHZ IMAGE SUGGESTS THE DEEP CORE CONVECTION IS
SUBSIDING, AND POSSIBLY BEING REPLACED BY A 60 NM RADIUS SECONDARY
EYEWALL FEATURE. THE INITIAL INTENSITY IS ASSESSED AT 85 KNOTS BASED
UPON DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T4.0-4.5 (77 TO
90 KNOTS) FROM MULTIPLE AGENCIES. UPPER LEVEL ANALYSIS CONTINUES TO
SHOW TC WINSTON IS IN A FAVORABLE ENVIRONMENT WITH GOOD POLEWARD
OUTFLOW AND WEAK-MODERATE (15 TO 20 KNOTS) VERTICAL WIND SHEAR
(VWS). TC 11P IS ACCELERATING SOUTHEASTWARD ALONG AN EXTENSION OF A
NEAR-EQUATORIAL RIDGE. AFTER TAU 36, SUB-TROPICAL RIDGING WILL BUILD
AHEAD OF, AND TO THE SOUTH OF TC 11P, RESULTING IN A TURN TO THE
SOUTHWEST. TC 11P IS FORECAST TO WEAKEN RAPIDLY AFTER TAU 24 AS IT
ENCOUNTERS INCREASING VWS AND COLDER (25-28C) SSTS.  WINSTON WILL
BECOME FULLY SUB-TROPICAL BY THE END OF THE FORECAST PERIOD AS IT
INTERACTS WITH AN APPROACHING UPPER LEVEL LOW. DYNAMIC MODEL
GUIDANCE IS IN GOOD AGREEMENT ON THE OVERALL SYNOPTIC STEERING
PATTERN, THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z IS 28 FEET. NEXT

REMARKS:
230900Z POSITION NEAR 20.2S 173.4E.
TROPICAL CYCLONE (TC) 11P (WINSTON), LOCATED APPROXIMATELY 312 NM
WEST-SOUTHWEST OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY INDICATES A SLOWLY-DECAYING LOW-LEVEL CIRCULATION CENTER
WITH CURVED DEEP CONVECTIVE BANDING. A 230453Z SSMIS 37 GHZ IMAGE
DEPICTS TIGHTLY-CURVED BANDING WRAPPING INTO A WELL-DEFINED, BROAD
CENTER, WHICH SUPPORTS THE CURRENT POSITION WITH FAIR CONFIDENCE.
THE INITIAL INTENSITY IS ASSESSED AT 75 KNOTS BASED ON THE PGTW
DVORAK CURRENT INTENSITY ESTIMATE OF 4.5 (77 KNOTS). UPPER-LEVEL
ANALYSIS CONTINUES TO REVEAL A FAVORABLE ENVIRONMENT WITH LOW TO
MODERATE VERTICAL WIND SHEAR (VWS) AND GOOD POLEWARD OUTFLOW. TC 11P
IS TRACKING ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL RIDGE
(STR) AND IS FORECAST TO CONTINUE TRACKING SOUTHWARD THROUGH TAU 24.
AFTER TAU 24, TC 11P WILL TURN SOUTHWESTWARD TO WEST-SOUTHWESTWARD
AS IT TRANSITIONS TO THE STEERING INFLUENCE OF A BUILDING STR TO THE
SOUTH. TC 11P IS EXPECTED TO WEAKEN SIGNIFICANTLY AFTER TAU 24 AS IT
ENCOUNTERS STRONG VWS AND COOLER SST. NEAR TAU 48, THE SYSTEM WILL
BEGIN TO INTERACT WITH AN UPPER-LEVEL SUBTROPICAL LOW. BY TAU 72,
11P WILL TRANSITION FULLY INTO A SUBTROPICAL LOW BUT IS EXPECTED TO
MAINTAIN GALE-FORCE WINDS. DYNAMIC MODEL GUIDANCE REMAINS IN GOOD
AGREEMENT, THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 25 FEET. NEXT

240300Z POSITION NEAR 23.0S 174.1E.
TROPICAL CYCLONE 11P (WINSTON), LOCATED APPROXIMATELY 360 NM
SOUTHWEST OF SUVA, FIJI, HAS TRACKED SOUTHWARD AT 11 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS AN ELONGATED AND FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC) WITH DEEP CONVECTION SHEARED TO THE SOUTH. A 232156Z GPM 36
GHZ IMAGE REVEALS A BROAD BUT DEFINED CENTER WITH DEEP CONVECTION
CONSTRAINED TO THE SOUTHERN SEMI-CIRCLE. THE INITIAL INTENSITY IS
ASSESSED AT 50 KNOTS BASED ON DVORAK CURRENT INTENSITY ESTIMATES
OF T3.0 (45 KNOTS) FROM PGTW AND KNES, AND ROUNDING UP TO ACCOUNT
FOR A 232125Z ASCAT PARTIAL PASS. UPPER-LEVEL ANALYSIS REVEALS
AN INCREASINGLY UNFAVORABLE ENVIRONMENT WITH STRONG (40 TO 50 KNOTS)
VERTICAL WIND SHEAR (VWS) AND DRY AIR ENTRAINMENT. TC 11P IS
TRACKING ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR)
AND IS FORECAST TO BEGIN TURNING SOUTHWESTWARD BY TAU 12 AND WEST-
SOUTHWESTWARD BY TAU 24, AS THE STEERING MECHANISM TRANSITIONS TO A
BUILDING STR TO THE SOUTH. TC WINSTON IS FORECAST TO CONTINUE
WEAKENING RAPIDLY THROUGH THE FORECAST PERIOD DUE TO HIGH VWS, DRY
AIR ENTRAINMENT, AND COLD SSTS. TC WINSTON IS ALSO INTERACTING WITH
AN UPPER-LEVEL LOW TO THE WEST. TC 11P WILL TRANSITION INTO A
SUBTROPICAL SYSTEM BY TAU 36, HOWEVER, IT IS POSSIBLE WINSTON MAY
DISSIPATE PRIOR TO THAT TIME. DYNAMIC MODEL GUIDANCE REMAINS IN GOOD
AGREEMENT, THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z IS 17 FEET. NEXT
WARNINGS AT 240900Z, 241500Z, 242100Z AND 250300Z.//

REVEALS SHALLOW BANDING WRAPPING AROUND A DEFINED BUT BROAD CENTER,
WHICH PROVIDES GOOD CONFIDENCE IN THE CURRENT POSITION. THE INITIAL
INTENSITY IS ASSESSED AT 50 KNOTS, HEDGED SLIGHTLY HIGHER THAN THE
PGTW DVORAK CURRENT INTENSITY ESTIMATE OF 3.0 (45 KNOTS), BASED ON
RECENT ASCAT DATA. UPPER-LEVEL ANALYSIS SHOWS AN UNFAVORABLE
ENVIRONMENT WITH STRONG (30 TO 40 KNOTS) VERTICAL WIND SHEAR (VWS).
TC 11P IS TRACKING ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL
RIDGE (STR) AND IS FORECAST TO TURN SOUTHWESTWARD TO WEST-
