MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
110 NM EITHER SIDE OF A LINE FROM 13.7S 111.8E TO 15.3S 108.5E
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 AT 280600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 13.8S 111.6E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 09
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.0S
113.3E, IS NOW LOCATED NEAR 13.8S 111.6E, APPROXIMATELY 525 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA. RECENT ANIMATED MULTI-
SPECTRAL SATELLITE IMAGERY SHOWS PERSISTENT CONVECTION WRAPPING
INTO A DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC). MICROWAVE
SATELLITE DATA, INCLUDING A 0440Z AMSR-2 PASS, INDICATE FORMATIVE
BANDING ALONG THE PERIPHERIES OF THE LLCC. THIS DISTURBANCE LIES
BENEATH AN UPPER-LEVEL RIDGE AXIS, IN AN AREA OF LOW VERTICAL
WIND SHEAR AND FAVORABLE POLEWARD AND EQUATORWARD OUTFLOW ALOFT.
WATER TEMPERATURES ARE CONDUCIVE FOR TROPICAL CYCLONE FORMATION,
AND NUMERIC MODELS INDICATE STEADY DEVELOPMENT OF THIS AREA DURING
THE NEXT FEW DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1005 MB. BASED ON IMPROVING ORGANIZATION AND FAVORABLE
ENVIRONMENTAL 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 290900Z.//

REMARKS:
282100Z POSITION NEAR 14.9S 109.9E.
TROPICAL CYCLONE 24S (TWENTYFOUR), LOCATED APPROXIMATELY 510 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED INFRARED SATELLITE
IMAGERY SHOWS THE SYSTEM HAS STEADILY CONSOLIDATED AS CONVECTIVE
BANDS WRAPPED TIGHTER INTO A WELL-DEFINED LOW LEVEL CIRCULATION
CENTER (LLCC). THE INITIAL POSITION IS BASED ON THE ABOVE ANIMATION
AND EXTRAPOLATED FROM A LLCC FEATURE IN THE 281427Z AMSU-B MICROWAVE
PASS WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS BASED ON AN
OVERALL ASSESSMENT OF RECENT SCATTEROMETRY DATA AND DVORAK ESTIMATES
FROM PGTW, KNES, AND ABRF. UPPER LEVEL ANALYSIS INDICATES THE CYCLONE
IS UNDERNEATH A RIDGE AXIS IN AN AREA OF LOW TO MODERATE (10-20 KNOT)
VERTICAL WIND SHEAR (VWS) THAT IS OFFSET BY EXCELLENT RADIAL OUTFLOW.
TC 24S IS TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A
NEAR-EQUATORIAL RIDGE (NER) TO THE EAST-SOUTHEAST. AFTER TAU 24, IT
IS EXPECTED TO ROUND THE NER AXIS AND RECURVE SOUTHEASTWARD TOWARDS
LEARMONTH. THE UPPER LEVEL ENVIRONMENT WILL REMAIN FAVORABLE OVER THE
NEXT 48 HOURS, PROMOTING A GRADUAL INTENSIFICATION, PEAKING AT 60
KNOTS AT TAUS 36-48. AFTERWARDS, INCREASING VWS, COOLING SSTS, AND
THE INFLUX OF COOL DRY AIR FROM THE SOUTHWEST WILL STEADILY ERODE THE
SYSTEM. TC 24S IS EXPECTED TO MAKE LANDFALL JUST SOUTH OF LEARMONTH
SHORTLY BEFORE TAU 96 AND DISSIPATE INLAND BY END OF FORECAST DUE TO
FRICTIONAL EFFECTS. THE INITIAL SET OF NUMERIC GUIDANCE IS IN AN
UNUSUALLY TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE FIRST JTWC
TRACK FORECAST ON THIS SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
281800Z IS 10 FEET. NEXT WARNINGS AT 290900Z AND 292100Z. THIS
WARNING SUPERSEDES AND CANCELS REF A (WTXS21 PGTW 280900).//

REMARKS:
290900Z POSITION NEAR 15.6S 109.1E.
TROPICAL CYCLONE 24S (QUANG), LOCATED APPROXIMATELY 494 NM NORTHWEST
OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 06 KNOTS
OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON
MULTISPECTRAL SATELLITE IMAGERY AND ASSOCIATED POSITION FIXES FROM
PGTW, KNES, AND APRF. THE INTENSITY OF 50 KNOTS IS CONSISTENT WITH
DVORAK SATELLITE INTENSITY ESTIMATES RANGING FROM 35 TO 55 KNOTS. TC
24S HAS STEADILY CONSOLIDATED AND INTENSIFIED OVER THE PAST 12 HOURS
UNDER THE INFLUENCE OF FAVORABLE UPPER-LEVEL CONDITIONS AND PASSAGE
OVER WARM WATER. THE SYSTEM IS TRACKING WEST-SOUTHWESTWARD ALONG THE
PERIPHERY OF A STEERING RIDGE TO THE EAST. THIS RIDGE IS EXPECTED TO
REORIENT TO A NORTHWEST TO SOUTHEAST ORIENTATION OVER THE NEXT 24
HOURS, STEERING TC 24S SOUTHEASTWARD TOWARD THE NORTHWEST COAST OF
AUSTRALIA. IN THE NEAR-TERM, STRONG POLEWARD OUTFLOW AND WARM WATER
SHOULD SUPPORT ADDITIONAL INTENSIFICATION. HOWEVER, INCREASING
VERTICAL WIND SHEAR AND DECREASING ALONG-TRACK SEA SURFACE
TEMPERATURES WILL WEAKEN THE SYSTEM AFTER TAU 24. BECAUSE SHEAR
VALUES ARE EXPECTED TO INCREASE SIGNIFICANTLY AFTER TAU 36,
DISSIPATION COULD OCCUR EARLIER THAN THE CURRENT FORECAST REFLECTS.
THE FORECAST TRACK HAS SHIFTED WESTWARD SLIGHTLY FROM THE PREVIOUS
FORECAST, FOLLOWING A WESTWARD SHIFT IN NUMERIC MODEL GUIDANCE OVER
THE PAST 12 HOURS. THE CURRENT FORECAST LIES SLIGHTLY TO THE EAST OF
THE MULTI-MODEL CONSENSUS, AND IS GENERALLY CONSISTENT WITH GLOBAL
MODEL SOLUTIONS ASIDE FROM THE EASTERN-OUTLYING UKMET MODEL FORECAST
TRACK. ALTHOUGH THERE IS SOME UNCERTAINTY IN THE EXACT TRACK TC 24S
WILL TAKE PRIOR TO LANDFALL, THERE IS SUFFICIENT AGREEMENT AMONG
GLOBAL MODEL SOLUTIONS TO LEND HIGH CONFIDENCE TO THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290600Z IS 20 FEET. NEXT
WARNINGS AT 292100Z AND 300900Z.//

REMARKS:
292100Z POSITION NEAR 16.7S 108.9E.
TROPICAL CYCLONE(TC) 24S (QUANG), LOCATED APPROXIMATELY 460 NM
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY DEPICTS SIGNIFICANTLY DEEPENED CONVECTION
WITH SPIRAL BANDING WRAPPING INTO A 10-NM EYE. THE CURRENT POSITION
IS BASED ON THE EYE FEATURE IN THE EIR LOOP WITH HIGH CONFIDENCE.
THE INITIAL INTENSITY HAS INCREASED GREATLY TO 90 KNOTS BASED ON
CONSENSUS DVORAK INTENSITY ESTIMATES OF T5.0 FROM ALL REPORTING
AGENCIES. TC 24S HAS RAPIDLY CONSOLIDATED AND INTENSIFIED OVER THE
PAST 12 HOURS UNDER THE INFLUENCE OF FAVORABLE ENVIRONMENTAL
CONDITIONS. THE SYSTEM IS TRACKING WEST-SOUTHWESTWARD ALONG THE
PERIPHERY OF A STEERING RIDGE TO THE EAST. THIS RIDGE IS EXPECTED TO
REORIENT TO A NORTHWEST TO SOUTHEAST ORIENTATION OVER THE NEXT 12
HOURS, STEERING TC 24S SOUTHEASTWARD TOWARD THE NORTHWEST COAST OF
AUSTRALIA. IN ADDITION TO THE WARM SEA SURFACE TEMPERATURES (SST) IN
THE AREA, FAVORABLE UPPER-LEVEL CONDITIONS ARE EXPECTED TO PERSIST,
ALLOWING TC QUANG TO FURTHER INTENSIFY LEADING TO A PEAK INTENSITY
OF 115 KNOTS BY TAU 12. AFTERWARDS, INCREASING VERTICAL WIND SHEAR
(VWS) AND DECREASING ALONG-TRACK SST WILL WEAKEN THE SYSTEM. BECAUSE
VWS VALUES ARE EXPECTED TO INCREASE SIGNIFICANTLY AFTER TAU 36,
DISSIPATION COULD OCCUR EARLIER THAN THE CURRENT FORECAST REFLECTS.
AVAILABLE MODEL GUIDANCE IS OVERALL IN GOOD AGREEMENT LENDING HIGH
CONFIDENCE IN THE JTWC TRACK FORECAST, WHICH IS POSITIONED CLOSE TO
MULTI-MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290600Z IS
20 FEET. NEXT WARNINGS AT 300300Z, 300900Z, 301500Z AND 302100Z.//

300900Z POSITION NEAR 18.2S 110.1E.
TROPICAL CYCLONE (TC) 24S (QUANG), LOCATED APPROXIMATELY 358 NM
NORTHWEST OF LEARMONTH, AUSTRALIA HAS TRACKED SOUTHEASTWARD AT
10 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS DEEP CONVECTIVE SPIRAL BANDING WRAPPING INTO
AN 8-NM CLOUD FILLED EYE THAT HAS BECOME ELONGATED DUE TO STRONG
UPPER LEVEL NORTHWESTERLY WINDS. THE INFRARED BD CURVE ENHANCEMENT
LOOP SHOWS THAT THE SYSTEM HAS MAINTAINED AN INTENSE COMPACT CENTRAL
CORE STRUCTURE; HOWEVER, IT HAS UNDERGONE SLIGHT WARMING OVER THE
PAST SIX HOURS. WATER VAPOR IMAGERY ILLUSTRATES SIGNIFICANT DRY AIR
WRAPPING AROUND THE WESTERN PERIPHERY, CONTRIBUTING TO THE WEAKENING
OF THE CYCLONES OUTER BANDS. UPPER LEVEL ANALYSIS INDICATES A
MODERATE ENVIRONMENT AS AN APPROACHING MID-LATITUDE SHORTWAVE TROUGH
TO THE WEST PROVIDES VIGOROUS POLEWARD OUTFLOW WITH MODERATE (15-20
KNOT) VERTICAL WIND SHEAR (VWS); HOWEVER, THE SYSTEMS MOVEMENT IS IN-
PHASE WITH THE SHEAR VECTOR PREVENTING SIGNIFICANT WEAKENING AT THIS
TIME. THE INITIAL POSITION IS BASED ON THE EYE FEATURE IN THE MSI
LOOP WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS BASED ON
CONCURRING DVORAK INTENSITY ESTIMATES OF T6.0 (115 KNOTS) FROM ALL
AGENCIES. TC QUANG IS TRACKING ALONG THE WESTERN PERIPHERY OF THE
DEEP LAYERED SUB-TROPICAL RIDGE (STR) TO THE NORTHEAST. THIS STR
WILL REMAIN THE DOMINANT STEERING MECHANISM THROUGHOUT THE FORECAST
PERIOD. AS TC 24S TRACKS SOUTHEASTWARD, INCREASED VWS AND
CONVERGENCE ALOFT WILL COMBINE TO RAPIDLY WEAKEN THE SYSTEM. BEYOND
TAU 36, THE SYSTEM WILL FURTHER WEAKEN DUE TO THE FRICTIONAL EFFECTS
OF LAND INTERACTION AS IT MAKES LANDFALL WEST OF LEARMONTH,
AUSTRALIA. DUE TO THE RAPIDLY DETERIORATING ENVIRONMENT IT IS
POSSIBLE THAT THE SYSTEM DISSIPATES PRIOR TO THE END OF THE FORECAST
PERIOD. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT ON THE FORECAST
TRACK LENDING TO HIGH CONFIDENCE IN THE JTWC FORECAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 300600Z IS 30 FEET. NEXT WARNINGS AT

REMARKS:
301500Z POSITION NEAR 19.4S 110.9E.
TROPICAL CYCLONE (TC) 24S (QUANG), LOCATED APPROXIMATELY 279 NM
NORTHWEST OF LEARMONTH, AUSTRALIA HAS TRACKED SOUTHEASTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS AN ELONGATED CENTRAL DENSE OVERCAST
FEATURE WITH A SMALL WARM SPOT IN THE BD CURVE ENHANCEMENT
SUPPORTING THE INITIAL POSITION WITH GOOD CONFIDENCE. WATER VAPOR
IMAGERY SHOWS THAT THE SPIRAL BANDING HAS WEAKENED SIGNIFICANTLY DUE
TO THE DRY AIR WRAPPING AROUND THE WESTERN AND NORTHERN PORTION OF
THE SYSTEM. A 301151Z SSMIS 37GHZ MICROWAVE IMAGE DEPICTS A WEAK
MICROWAVE EYE FEATURE WITH THE BULK OF CONVECTION DISPLACED TO THE
SOUTHEAST. UPPER LEVEL ANALYSIS CONTINUES TO INDICATE A MODERATE,
BUT DECLINING, ENVIRONMENT WITH MODERATE (20-25 KNOT) NORTHWESTERLY
VERTICAL WIND SHEAR (VWS) DUE TO THE APPROACHING SHORTWAVE TROUGH
FROM THE WEST. THE INITIAL INTENSITY IS SLIGHTLY LOWER THAN CURRENT
INTENSITY ESTIMATES OF T6.0 TO ILLUSTRATE THE DETERIORATING
STRUCTURE OF THE SYSTEM AND SUPPORTED BY AGENCY DVORAK ESTIMATES
SHOWING A SIGNIFICANT WEAKENING OF THE CYCLONES CORE AND A SATCON
INTENSITY ESTIMATE OF 100 KNOTS. TC QUANG IS TRACKING ALONG THE
WESTERN PERIPHERY OF THE DEEP LAYERED SUB-TROPICAL RIDGE (STR) TO
THE NORTHEAST. THIS STR WILL REMAIN THE DOMINANT STEERING MECHANISM
THROUGHOUT THE FORECAST PERIOD. AS TC 24S CONTINUES TO TRACK
SOUTHEASTWARD, INCREASING VWS AND DECREASING DIVERGENCE ALOFT WILL
COMBINE TO RAPIDLY WEAKEN THE SYSTEM. BEYOND TAU 24, THE SYSTEM
WILL FURTHER WEAKEN DUE TO LAND INTERACTION AS IT MAKES LANDFALL
WEST OF LEARMONTH, AUSTRALIA. DUE TO THE RAPIDLY DETERIORATING
ENVIRONMENT IT IS POSSIBLE THAT THE SYSTEM DISSIPATES PRIOR TO THE
END OF THE FORECAST PERIOD. DYNAMIC MODEL GUIDANCE REMAINS IN GOOD
AGREEMENT ON THE FORECAST TRACK LENDING TO HIGH CONFIDENCE IN THE
JTWC FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 301200Z IS 28
FEET. NEXT WARNINGS AT 302100Z, 010300Z, 010900Z AND 011500Z.//

MHS 89GHZ MICROWAVE IMAGE SHOWS A WEAK ELONGATED LLCC WITH DRY AIR
WRAPPING COMPLETELY AROUND THE NORTHERN PERIPHERY OF THE SYSTEM. THE
CURRENT POSITION IS BASED ON THE PARTIALLY EXPOSED LLCC IN THE MSI
LOOP AND THE AFOREMENTIONED MICROWAVE IMAGE WITH GOOD CONFIDENCE.
THE INITIAL INTENSITY HAS BEEN LOWERED TO 70 KNOTS BASED ON THE POOR
LLCC STRUCTURE AND AN ASSESSMENT OF DVORAK INTENSITY ESTIMATES FROM
ALL REPORTING AGENCIES. IT IS SUPPORTED BY A RECENT SATCON INTENSITY
ESTIMATE OF 76 KNOTS AND RECENT OBSERVATIONS FROM LEARMONTH. UPPER
LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED IN AN AREA OF STRONG
(40 TO 50 KNOT) NORTHWESTERLY VERTICAL WIND SHEAR (VWS) THAT IS
PREVAILING OVER THE EXCELLENT POLEWARD OUTFLOW. TC QUANG IS TRACKING
SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF THE DEEP LAYERED SUB-
