MSGID/GENADMIN/NAVMARFCSTCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 150 NM RADIUS OF 14.6S 167.8E WITHIN THE NEXT 12 TO 24 HOURS.
AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUMBERED TROPICAL CY-
CLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO
BE 25 TO 30 KNOTS. METSAT IMAGERY AT 101800Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 14.6S 167.8E.  THE SYSTEM IS
MOVING WEST-SOUTHWESTWARD AT 03 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.4S
168.4E IS NOW LOCATED NEAR 14.6S 167.8E, APPROXIMATELY 70 NM EAST
OF VANUATU. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY
INDICATES INCREASED DEEP CONVECTION CONSOLIDATING AROUND A DEVELOPING
LOW LEVEL CIRCULATION CENTER (LLCC). SURFACE OBSERVATIONS AT 101800Z
FROM INDOTRANS MAKASSAR, SOLA VANUA VANUATU (NVSC), AND PEKOA
AIRPORT (NVSS) SHOW A DECREASE IN SEA LEVEL PRESSURE RANGING FROM
1.5 TO 3 MB WITHIN THE LAST 24 HOURS. A 101752Z SSMIS 91 GHZ
MICROWAVE IMAGE SHOWS MULTIPLE CONVECTIVE BANDS WRAPPING FROM THE
SOUTHEAST INTO A BROADLY DEFINED LLCC. UPPER LEVEL ANALYSIS
INDICATES THAT THE SYSTEM IS LOCATED UNDER THE SUBTROPICAL RIDGE
AXIS WITH WEAK VERTICAL WIND SHEAR AND FAVORABLE EQUATORWARD
OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB.
DUE TO INCREASED CONSOLIDATION OF THE LLCC AND DECREASING SURFACE
PRESSURE OBSERVATIONS NEAR THE SYSTEM CENTER, THE POTENTIAL FOR
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY

REMARKS:
112100Z POSITION NEAR 14.6S 166.2E.
TROPICAL CYCLONE (TC) 20P (TWENTY), LOCATED APPROXIMATELY 20 NM WEST
OF VANUATU, HAS TRACKED WESTWARD AT 05 KNOTS DURING THE PAST SIX
HOURS. ANIMATED INFRARED SATELLITE IMAGERY AND A 111444Z AMSU
MICROWAVE IMAGE INDICATE CONSOLIDATION OF DEEP CONVECTION AROUND A
LOW LEVEL CIRCULATION CENTER WITH MULTIPLE CONVECTIVE BANDS WRAPPING
IN FROM THE SOUTHEAST. THE CURRENT INTENSITY IS BASED ON
OBSERVATIONS FROM PEKOA AIRPORT ON VANUATU (NVSS), WHICH SHOWS SEA
LEVEL PRESSURE AT 998 MB AND WINDS OUT OF THE SOUTH-SOUTHEAST AT 30
KNOTS. IN ADDITION, DVORAK ESTIMATES RANGE FROM 30 TO 35 KNOTS FROM
PGTW, KNES, AND PHFO. UPPER LEVEL ANALYSIS INDICATES THAT THE SYSTEM
IS TRACKING WESTWARD ALONG THE NORTHEASTERN PERIPHERY OF THE
SUBTROPICAL RIDGE WITH GOOD RADIAL OUTFLOW AND WEAK VERTICAL WIND
SHEAR ALOFT. THE SYSTEM IS FORECAST TO TRACK WEST-NORTHWEST IN THE
EARLY TAUS, HOWEVER, IN THE LATER TAUS THE SYSTEM IS EXPECTED TO
SLOW AND TURN SLIGHTLY SOUTHWESTWARD AS IT ENCOUNTERS A COMPETING
STEERING RIDGE TO THE NORTH AND INTERACTS WITH AN APPROACHING
MIDLATITUDE TROUGH. NUMERICAL GUIDANCE IS IN GOOD AGREEMENT WITH
THIS FORECAST WITH THE EXCEPTION OF WBAR, WHICH ERRONEOUSLY RECURVES
THE SYSTEM SHARPLY TO THE NORTHEAST. THIS WARNING SUPERSEDES AND
CANCELS REF A, NAVMARFCSTCEN 102200Z MAR 10 TROPICAL CYCLONE
FORMATION ALERT (WTPS21 PGTW 102200) MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 111800Z IS 10 FEET. NEXT WARNINGS AT 120900Z AND 122100Z. REFER

REMARKS:
120900Z POSITION NEAR 14.8S 165.4E.
TROPICAL CYCLONE (TC) 20P (TWENTY), LOCATED APPROXIMATELY 50 NM WEST
OF VANUATU, HAS TRACKED WESTWARD AT 06 KNOTS OVER THE PAST SIX
HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A WELL-DEFINED
LOW LEVEL CIRCULATION CENTER (LLCC) WITH BANDING CONVECTION STARTING
TO WRAP INTO THE SYSTEM CENTER. ENVIRONMENTAL ANALYSIS INDICATES THE
SYSTEM IS LOCATED JUST EQUATORWARD OF THE NARROW (AS MEASURED NORTH-
SOUTH) SUBTROPICAL RIDGE AXIS AND AN UPPER-LEVEL DIFFLUENT SOURCE
REGION LOCATED ABOUT 5 DEGREES SOUTHEAST OF TC 20P IS ENHANCING
STRONG RADIAL OUTFLOW. THROUGH TAU 72, TC 20P WILL CONTINUE TO TRACK
ALONG THE NORTHERN PERIPHERY OF THE SUBTROPICAL STEERING RIDGE AND
INTENSIFY DUE TO FAVORABLE UPPER-LEVEL OUTFLOW AND HIGH OCEAN HEAT
CONTENT (OHC) VALUES. AFTER TAU 72, TC 20P WILL START TO SLOW AND
DIP TO THE SOUTH-SOUTHWEST AS A NEAR EQUATORIAL RIDGE IS FORECAST TO
BUILD AND GENERATE A COMPETING/WEAK STEERING ENVIRONMENT.
NEVERTHELESS, THE CYCLONE WILL FURTHER INTENSIFY THROUGH THE
EXTENDED TAU'S DUE TO EVEN MORE ROBUST OHC VALUES. THE MODEL
GUIDANCE IS IN GOOD AGREEMENT THROUGH 72 HOURS BEFORE IT DIVERGES A
BIT AS SOME SOLUTIONS START TO DEPICT A SHARP TURN BACK TO THE EAST.
THE FACT THE MODELS ARE SLOWING IN THE EXTENDED TAU'S AND BECOMING
LESS AGREEABLE POINTS TO THE WEAK STEERING ENVIRONMENT PREVIOUSLY
DISCUSSED. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120600Z IS 13 FEET.

REMARKS:
122100Z POSITION NEAR 14.0S 164.4E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 105 NM
WEST-NORTHWEST OF VANUATU, HAS TRACKED WEST-NORTHWESTWARD AT 03 KTS
OVER THE PAST SIX HOURS. ANIMATED WATER VAPOR IMAGERY SHOWS IMPROVED
CONSOLIDATION, RADIAL OUTFLOW AND DEEPER BANDING CONVECTION WRAPPING
TIGHTLY INTO THE SYSTEM CENTER. UPPER LEVEL ANALYSIS INDICATES THE
SYSTEM IS LOCATED JUST EQUATORWARD OF SUBTROPICAL RIDGE AXIS IN AN
AREA OF LOW VERTICAL WIND SHEAR. THE CURRENT POSITION IS BASED ON A
121418Z AMSR-E MICROWAVE IMAGE SHOWING A HIGHLY REFLECTIVE BAND
WRAPPING ALMOST COMPLETELY AROUND THE LOW LEVEL CIRCULATION CENTER.
THE CURRENT INTENSITY IS BASED ON THE DVORAK ESTIMATE FROM PGTW. TC
20P IS EXPECTED TO CONTINUE TRACKING WESTWARD ALONG THE NORTHERN
PERIPHERY OF THE SUBTROPICAL RIDGE LOCATED TO THE SOUTH AND WILL
INTENSIFY DUE TO FAVORABLE UPPER-LEVEL OUTFLOW AND HIGH OCEAN HEAT
CONTENT (OHC) VALUES. AFTER TAU 72, TC ULUI WILL START TO SLOW AND
DIP TO THE SOUTH-SOUTHWEST AS A NEAR EQUATORIAL RIDGE IS FORECAST TO
BUILD AND GENERATE A COMPETING/WEAK STEERING ENVIRONMENT. THE MODEL
GUIDANCE IS IN GOOD AGREEMENT THROUGH 72 HOURS BEFORE IT DIVERGES A
BIT ON THE SPEED OF ADVANCE WITH SOME, NOTABLY UKMET, AT A FASTER
RATE. MOST OF THE MODELS FAVOR A SLOW DOWN IN THE EXTENDED TAU'S.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 121800Z IS 15 FEET. NEXT WARNINGS
AT 130900Z AND 132100Z. REFER TO TROPICAL CYCLONE 19P (TOMAS)

REMARKS:
130900Z POSITION NEAR 13.3S 163.4E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 185 NM
WEST-NORTHWEST OF VANUATU, HAS TRACKED WEST-NORTHWESTWARD AT 05 KTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS IMPROVED CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL
CIRCULATION CENTER (LLCC) WITH A 130232Z AMSR-E IMAGE DEPICTING A
WELL DEVELOPED MICROWAVE EYE. INITIAL POSITION IS BASED ON TIGHTLY
WRAPPED BANDING IN MSI WITH MODERATE CONFIDENCE. INITIAL INTENSITY
IS BASED ON PGTW AND ABRF DVORAK INTENSITY ESTIMATES OF 65 KNOTS.
UPPER LEVEL ANALYSIS INDICATES TC 20P IS LOCATED EQUATORWARD OF THE
SUBTROPICAL RIDGE (STR) AXIS, IN AN AREA OF LOW VERTICAL WIND SHEAR
AND GOOD RADIAL OUTFLOW IN THE NORTHERN SEMI-CIRCLE. AN UPPER LEVEL
TROUGH TO THE SOUTH IS PROVIDING MINIMAL POLEWARD OUTFLOW. TC 20P IS
CURRENTLY TRACKING TO THE WEST-NORTHWEST UNDER THE INFLUENCE OF A
STR LOCATED OVER EASTERN AUSTRALIA THAT EXTENDS EASTWARD TOWARDS
NOUMEA. BASED ON FAVORABLE SURFACE CONDITIONS AND CONTINUED UPPER
LEVEL SUPPORT THE FORECAST HAS TC 20P INTENSIFYING THROUGH TAU 96
WITH A SLIGHT DROP AT TAU 120 BASED ON AN UPPER LEVEL TROUGH
INTERRUPTING POLEWARD OUTFLOW BRIEFLY AS IT TRACKS EASTWARD ALONG
THE SOUTHERN HALF OF TC 20P. MODEL GUIDANCE SUGGESTS THAT THE MID-
LATITUDE TROUGH WILL ALSO CAUSE THE STR OVER AUSTRALIA TO WEAKEN
ALONG THE EASTERN PERIPHERY, LEADING TO A WEAKENING OF THE PRIMARY
STEERING INFLUENCE. THE FORECAST HAS THE TRACK SPEEDS DECREASING
AFTER TAU 72 AS ULUI MOVES INTO THE WEAKER STEERING ENVIRONMENT.
ULUI IS EXPECTED TO SLOWLY DRIFT TO THE WEST-SOUTHWEST IN THE WEAK
STEERING ENVIRONMENT BEYOND TAU 72. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 130600Z IS 20 FEET. NEXT WARNINGS AT 132100Z AND 140900Z. REFER

REMARKS:
131500Z POSITION NEAR 13.0S 162.7E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 230 NM WEST-
NORTHWEST OF VANUATU, HAS TRACKED WEST-NORTHWESTWARD AT 07 KTS OVER
THE PAST SIX HOURS. TC 20P HAS UNDERGONE A PERIOD OF RAPID INTENSIFI-
CATION OVER THE PAST SIX HOURS, WITH THE CURRENT INTENSITY AT 105
KNOTS, AND DVORAK INTENSITY ESTIMATES RANGING BETWEEN 90 AND 115
KNOTS. ADDITIONALLY, INTENSITY GUIDANCE HAS INCREASED WITH A MAXIMUM
INTENSITY OF 150 KNOTS WITHIN THE NEXT 48 HOURS, AND SLOWLY DECREA-
SING AS THE UPPER LEVEL OUTFLOW DIMINISHES WITH THE APPROACH OF A
MID-LATITUDE TROUGH. IN THE EARLY PORTION OF THE FORECAST STRONG
UPPER LEVEL SUPPORT IN ASSOCIATION WITH HIGH SEA SURFACE TEMPERATURES
AND OCEAN HEAT CONTENT WILL ALLOW THE CONTINUED DEVELOPMENT OF ULUI.
AROUND TAU 72 THE MID-LATITUDE TROUGH WILL BEGIN TO HINDER THE POLE-
WARD OUTFLOW CHANNEL, CAUSING THE SLIGHT WEAKENING TREND IN THE
FORECAST. HOWEVER, THIS WILL ONLY BE A MINOR IMPACT TO THE SYSTEM AS
IT MAINTAINS AS A STRONG TROPICAL CYCLONE THROUGHOUT THE FORECAST
PERIOD. THE TRACK WILL REMAIN CONSISTENT WITH PREVIOUS FORECASTS,
WITH TC 20P TRACKING WEST-NORTHWESTWARD UNDER THE INFLUENCE OF A SUB-
TROPICAL RIDGE (STR) LOCATED OVER WESTERN AUSTRALIA, EXTENDING TO NEW
CALEDONIA. MODEL GUIDANCE SUGGESTS THAT THE MID-LATITUDE TROUGH WILL
CAUSE THE STR OVER AUSTRALIA TO WEAKEN ALONG THE EASTERN PERIPHERY,
LEADING TO A WEAK STEERING ENVIRONMENT BEYOND TAU 72. ULUI IS EX-
PECTED TO SLOWLY DRIFT TO THE WEST-SOUTHWEST IN THE WEAK STEERING
ENVIRONMENT THROUGH TAU 120. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
131200Z IS 24 FEET. NEXT WARNINGS AT 140300Z AND 141500Z. REFER TO

REMARKS:
140300Z POSITION NEAR 12.7S 161.4E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 310 NM WEST-
NORTHWEST OF VANUATU, HAS TRACKED WEST-NORTHWESTWARD AT 08 KTS OVER
THE PAST SIX HOURS. DVORAK INTENSITY ESTIMATES FROM PGTW, ABRF, AND
KNES INDICATE TC 20P CONTINUES TO INTENSIFY AT A HIGHER THAN NORMAL
RATE. THE CURRENT POSITION IS BASED ON ANIMATED MULTISPECTRAL IMAGERY
SHOWING A WELL-DEFINED 10-NM DIAMETER EYE. UPPER LEVEL ANALYSIS
INDICATES THAT THE SYSTEM HAS DEVELOPED A MESOSCALE ANTICYCLONE ALOFT
THAT IS ENHANCING EXCELLENT RADIAL OUTFLOW. TC 20P IS EXPECTED TO
INTENSIFY FURTHER AS IT TRACKS ALONG THE NORTHERN PERIPHERY OF THE
STEERING RIDGE TO THE SOUTH, ALBEIT AT A SLOWER RATE OVER THE NEXT 48
HOURS AS IT CONTINUES TO ENJOY LOW VERTICAL WIND SHEAR AND HIGH SEA
SURFACE TEMPERATURES. BY TAU 72 AN APPROACHING MID-LATITUDE TROUGH
WILL BEGIN TO HINDER THE POLEWARD OUTFLOW CHANNEL, CAUSING THE SLIGHT
WEAKENING TREND IN THE FORECAST.
THIS TROUGH WILL CAUSE A WEAKNESS IN THE RIDGE LEADING TO A WEAK
STEERING ENVIRONMENT BEYOND TAU 72. TC ULUI IS THEN EXPECTED TO
SLOWLY DRIFT TO THE SOUTH AS A NEAR EQUATORIAL RIDGE TO THE NORTHEAST
BUILDS AND STEERS THE SYSTEM POLEWARD. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 140000Z IS 30 FEET. NEXT WARNINGS AT 141500Z AND 150300Z.

REMARKS:
141500Z POSITION NEAR 12.8S 160.2E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 375 NM WEST-
NORTHWEST OF VANUATU, HAS TRACKED WESTWARD AT 07 KTS OVER THE PAST
SIX HOURS. ANIMATED INFRARED IMAGERY SHOWS CONTINUED CONVECTIVE
BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER WITH A 10 NM
EYE. INITIAL INTENSITY IS BASED ON PGTW AND KNES DVORAK INTENSITY
ESTIMATES OF 140 KNOTS. UPPER LEVEL ANALYSIS INDICATES AN
ANTICYCLONE ALOFT IS PROVIDING LOW VERTICAL WIND SHEAR (VWS) AND
STRONG RADIAL OUTFLOW. TC 20P IS CURRENTLY TRACKING ON THE NORTHERN
PERIPHERY OF THE SUBTROPICAL STEERING RIDGE IN AN AREA OF HIGH OCEAN
HEAT CONTENT AND WILL CONTINUE THROUGH TAU 36. ULUI WILL THEN BEGIN
TO TURN SOUTHWARD AS THE SUBTROPICAL RIDGE (STR) WEAKENS DUE TO AN
UPPER LEVEL, MID-LATITUDE TROUGH AND A NEAR EQUATORIAL RIDGE BUILDS
IN. BY TAU 96, THE STR WILL BUILD BACK IN AND TURN THE SYSTEM SOUTH-
SOUTHWESTWARD. INTENSITIES WILL REMAIN PERSISTENT AND BEGIN TO
DECREASE AFTER TAU 48 AS IT ENCOUNTERS HIGHER VWS. NUMERICAL MODEL
GUIDANCE IS IN GOOD AGREEMENT, THROUGH TAU 48, WITH THE EXCEPTION OF
GFS. MODEL SPREAD THEN INCREASES WITH THE TIMING OF THE TURN
SOUTHWARD. THIS FORECAST IS CONSISTENT WITH MODEL CONSENSUS. GFS
TURNS THE SYSTEM EARLIER WITH AN UNLIKELY SHARP TURN TO THE
SOUTHEAST DUE TO A STRONGER NEAR EQUATORIAL RIDGE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 141200Z IS 30 FEET. NEXT WARNINGS AT
150300Z AND 151500Z. REFER TO TROPICAL CYCLONE 19P (TOMAS) WARNINGS

TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 425 NM WEST-

THE PAST SIX HOURS. ANIMATED INFRARED IMAGERY SHOWS THE SYSTEM HAS
MAINTAINED CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION
CENTER WITH A 25 NM EYE. CURRENT INTENSITY IS BASED ON PGTW AND KNES
DVORAK INTENSITY ESTIMATES OF 130 KNOTS. UPPER LEVEL ANALYSIS
INDICATES TC 20P HAS SUSTAINED A MESOSCALE ANTICYCLONE ALOFT THAT
ENHANCING GOOD RADIAL OUTFLOW ESPECIALLY ON THE WESTERN SEMI-CIRCLE
IN AN AREA OF LOW VERTICAL WIND SHEAR (VWS). TC 20P IS CURRENTLY
TRACKING ON THE NORTHERN PERIPHERY OF THE SUBTROPICAL STEERING RIDGE
IN AN AREA OF HIGH OCEAN HEAT CONTENT AND WILL CONTINUE THROUGH TAU
24. TC ULUI WILL THEN BEGIN TO TURN SOUTHWARD AS THE SUBTROPICAL
RIDGE (STR)WEAKENS WITH THE APPROACH OF A MID-LATITUDE TROUGH AND A
NEAR EQUATORIAL RIDGE (NER) TO THE NORTHEAST BUILDS. BY TAU 72, THE
STR WILL BUILD BACK IN AND TURN THE SYSTEM SOUTHWESTWARD. THE CURRENT
INTENSITY WILL PREVAIL WITH THE FAVORABLE CONDITIONS MENTIONED ABOVE
BUT WILL BEGIN TO DECREASE AFTER TAU 36 AS IT ENCOUNTERS HIGHER VWS.
THE AVAILABLE NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT, THROUGH
TAU 36. MODEL SPREAD THEN INCREASES WITH THE TIMING AND DEGREE OF THE
TURN SOUTHWARD. GFDN, GFS, AND NOGAPS FAVOR AN EARLIER AND SHARPER
TURN TO THE SOUTHEAST PRESUMABLY DUE TO A STRONGER NER. THIS FORECAST

REMARKS:
151500Z POSITION NEAR 13.1S 158.4E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 925 NM NORTH-
NORTHEAST OF BRISBANE, AUSTRALIA HAS TRACKED WESTWARD AT 04 KTS OVER
THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS DEEP
CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER
(LLCC) AND A 180820Z SSMIS MICROWAVE IMAGE SHOWS THE MAJORITY OF THE
DEEP CONVECTION IS LOCATED ON THE WESTERN PERIPHERY. THE INITIAL
POSITION IS BASED ON TIGHTLY CURVED BANDING AND THE INITIAL
INTENSITY IS BASED ON PGTW DVORAK INTENSITY ESTIMATES OF 130 KNOTS.
UPPER LEVEL ANALYSIS INDICATES AN ANTICYCLONE ALOFT IS PROVIDING LOW
VERTICAL WIND SHEAR (VWS) AND GOOD RADIAL OUTFLOW. ULUI CONTINUES TO
TRACK ALONG THE NORTHERN PERIPHERY OF THE SUBTROPICAL STEERING RIDGE
IN AN AREA OF HIGH OCEAN HEAT CONTENT (OHC) AND WARM SEA SURFACE
TEMPERATURES. TC 20P IS FORECAST TO CONTINUE TO TRACK WESTWARD FOR
THE NEXT 12 HOURS AND THEN BEGIN TO TURN SOUTHWARD AS THE
SUBTROPICAL RIDGE (STR) WEAKENS DUE TO AN UPPER LEVEL, MID-LATITUDE
TROUGH AND A NEAR EQUATORIAL RIDGE (NER) BUILDING IN. BY TAU 72, THE
STR SHOULD BUILD BACK IN AND BEGIN SPEEDING UP TO THE SOUTHWEST.
INTENSITIES ARE FORECAST TO STEADILY DECREASE WITH INCREASING VWS
AND DECREASING OHC. NUMERICAL MODEL GUIDANCE IS DIVIDED IN THE
TIMING OF THE TURN TO THE SOUTHWEST. THIS FORECAST WAS IN AGREEMENT
WITH THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151200Z
IS 36 FEET. NEXT WARNINGS AT 160300Z AND 161500Z. REFER TO TROPICAL
CYCLONE 19P (TOMAS) WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY

REMARKS:
160300Z POSITION NEAR 13.5S 158.1E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATLEY 750 NM EAST-
NORTHEAST OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 02
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THE CYCLONE IS WELL ORGANIZED WITH STRONG RADIAL
OUTFLOW AND A 20-NM RAGGED EYE WHILE A 151829Z SSMIS MICROWAVE IMAGE
INDICATES THE SYSTEM IS VERTICALLY TILTED TO THE NORTH-NORTHWEST.
THEREFORE, POSITION CONFIDENCE HAS WANED DUE TO THE AMBIGUITY
PRESENTED BY INFRARED IMAGERY AND A LACK OF MICROWAVE IMAGERY NEAR
16/00Z. NEVERTHELESS, THERE IS GOOD CONFIDENCE IN THE INITIAL
INTENSITY AS DVORAK ESTIMATES FROM PGTW AND ABRF AGREE AT 115 KNOTS.
TC ULUI HAS TRACKED ALONG THE NORTHEASTERN PERIPHERY OF A
SUBTROPICAL STEERING RIDGE OVER THE LAST 12 HOURS. OVER THE NEXT 24-
36 HOURS, TC ULUI WILL START TO TRACK MORE SOUTHEASTWARD AS A
PASSING MID-LATITUDE TROUGH CAUSES THE SUBTROPICAL RIDGE TO RECEDE
AND ENABLES A BUILDING NEAR EQUATORIAL RIDGE (NER) TO BECOME THE
DOMINATE STEERING INFLUENCE. BY TAU 48, THE MID-LATIUDE TROUGH WILL
PASS TO THE EAST AND ALLOW THE SUBTROPICAL RIDGE OVER AUSTRALIA TO
RE-DEVELOPS THIS RE-DEVELOPMENT OF THE STEERING RIDGE WILL ALLOW TC
ULUI TO TRACK MORE SOUTHWESTWARD AFTER TAU 48. ADDITIONALLY, ROBUST
OCEAN HEAT CONTENT VALUES AND ENHANCED POLEWARD OUTFLOW BY TAU 48
WILL ENABLE TC ULUI TO MAINTAIN ITS INTENSITY THROUGH 72 HOURS.
NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THIS SCENARIO
THOUGH THE DIFFERENT MODELS EACH CHARACTERIZE THE DEGREE TO WHICH
THE SYSTEM WILL TURN BACK TO THE SOUTHWEST DIFFERENTLY. THE UKMO
SOLUTION IS ON THE FAR WEST EDGE OF THE ENVELOP WHILE THE GFS MODEL
TRACKER SHOWS THE GREATEST SOUTHEAST TURN. MAXIMUM SIGNIFICANT WAVE

REMARKS:
161500Z POSITION NEAR 13.6S 157.8E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 725 NM EAST-
NORTHEAST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 03
KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED INFRARED SATELLITE
IMAGERY SHOWS MULTIPLE SPIRAL BANDS WRAPPING IN TOWARDS AN IRREGULAR
AND CLOUD-FILLED 20 NM EYE. RADIAL OUTFLOW ALOFT CONTINUES TO
SUPPORT A 110 KNOT SYSTEM, IN ADDITION TO FAVORABLE SEA SURFACE
TEMPERATURES AND OCEANIC HEAT CONTENT. THE LATEST DVORAK CURRENT
INTENSITY ESTIMATES FROM PGTW AND ABRF RANGE FROM 102 TO 115 KNOTS.
THE SYSTEM IS CURRENTLY DRIFTING SOUTH (TOWARDS A TROUGH-INDUCED
WEAKNESS IN THE RIDGE) IN A COMPETING STEERING ENVIRONMENT BETWEEN
THE SUBTROPICAL RIDGE TO THE SOUTHWEST AND THE NEAR EQUATORIAL RIDGE
TO THE NORTHEAST. THE TROUGH WILL PUSH DOWNSTREAM WITHIN THE NEXT 24
TO 36 HOURS ALLOWING THE SUBTROPICAL RIDGE TO RE-ESTABLISH ITSELF TO
THE SOUTH OF THE TC. THIS WILL ALLOW ULUI TO TURN WEST TOWARDS THE
EAST COAST OF AUSTRALIA AROUND TAU 48 AS IT BECOMES THE DOMINANT
STEERING FORCE. THE SYSTEM WILL GRADUALLY WEAKEN AS IT ENCOUNTERS
INCREASED VERTICAL WIND SHEAR SOUTH OF 20S. PRIOR TO THAT THE
INTENSITY SHOULD HOVER AROUND 100 KNOTS WITH ENVIRONMENTAL
CONDITIONS REMAINING FAIRLY CONSTANT. THE FORECAST CLOSELY FOLLOWS
THE MODEL CONSENSUS, WHICH HAS CHANGED LITTLE SINCE THE PREVIOUS 2
RUNS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 161200Z IS 27 FEET. NEXT
WARNINGS AT 170300Z AND 171500Z. REFER TO TROPICAL CYCLONE 19P

LATITUDE TROUGH-INDUCED WEAKNESS IN THE RIDGE) IN A COMPETING
STEERING ENVIRONMENT CREATED BY THE SUBTROPICAL RIDGE TO THE
SOUTHWEST AND THE NEAR EQUATORIAL RIDGE TO THE NORTHEAST. THE TROUGH
WILL PUSH DOWNSTREAM WITHIN THE NEXT 12 TO 24 HOURS, ALLOWING THE
SUBTROPICAL RIDGE TO RE-ESTABLISH ITSELF TO THE SOUTH OF THE TC.
THIS WILL ENABLE TC ULUI TO TURN WEST TOWARDS THE NORTHEAST COAST OF
AUSTRALIA AFTER TAU 36. THE INTENSITY SHOULD HOVER AROUND 100 KNOTS
WITH ENVIRONMENTAL CONDITIONS REMAINING FAIRLY CONSTANT THROUGH THE
FIRST 72 HOURS BEFORE SLOWLY WEAKENING DUE TO DECREASING POLEWARD
OUTFLOW AND LESS FAVORABLE OCEAN HEAT CONTENT VALUES. THE FORECAST
CLOSELY FOLLOWS THE MODEL CONSENSUS, WHICH HAS CHANGED LITTLE OVER
THE LAST DAY. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 170000Z IS 27 FEET.

REMARKS:
171500Z POSITION NEAR 14.6S 158.0E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 730 NM EAST
OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 04 KNOTS
OVER THE PAST SIX HOURS. AFTER BEING QUASISTATIONARY FOR NEARLY 36
HOURS ULUI HAS BEGUN TO ACCELERATE WITH THE STRENGTHENING OF THE
SUBTROPICAL STEERING RIDGE TO THE SOUTH. THE TROUGH THAT HAD BEEN
RESPONSIBLE FOR THE WEAKENED STATE OF THIS RIDGE IS POSITIONED TO
MOVE DOWNSTREAM WITHIN THE NEXT 12 TO 24 HOURS. WITH THE TROUGH
DOWNSTREAM THE RIDGE WILL FURTHER STRENGTHEN AND TRACK THE CYCLONE
TOWARDS THE EAST COAST OF AUSTRALIA, OF WHICH THE MODEL GUIDANCE IS
NOW IN EXCELLENT AGREEMENT WITH. THE INITIAL INTENSITY HAS DECREASED
TO 100 KNOTS IN RESPONSE WEAKENED CENTRAL CONVECTION, WHICH IS MOST
LIKELY THE CONSEQUENCE OF UPWELLING OF COOLER SUB-SURFACE WATER.
RECENTLY IMPROVED POLEWARD VENTING SHOULD HELP TO OFFSET SIGNIFICANT
DECAY OF CENTRAL CONVECTION AND STABILIZE THE INTENSITY NEAR 100
KNOTS FOR THE NEXT DAY. THE 0600Z DVORAK INTENSITY ESTIMATE FROM
PGTW INDICATES A 77 TO 102 KNOT SYSTEM. THE SYSTEM WILL COME ASHORE
SHORTLY AFTER TAU 72 AND WILL DISSIPATE OVER INTERIOR QUEENSLAND
NEAR TAU 120. THE CYCLONE WILL SLOWLY WEAKEN PRIOR TO LANDFALL DUE
TO RESTRICTED POLEWARD OUTFLOW AND ELEVATED VERTICAL WIND SHEAR.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171200Z IS 23 FEET. NEXT WARNINGS
AT 180300Z AND 181500Z. REFER TO TROPICAL CYCLONE 19P (TOMAS)

BY THE SLOW-MOVING CYCLONE. AS A SUBTROPICAL RIDGE BUILDS TO THE
SOUTH OVER THE NEXT 12 TO 24 HOURS, TC 20P IS EXPECTED TO TURN
WESTWARD AND ACCELERATE TOWARD THE NORTHEASTERN QUEENSLAND COAST,
MAKING LANDFALL AROUND TAU 72. MOST OF THE NUMERICAL MODEL GUIDANCE
IS IN GOOD AGREEMENT WITH THE CURRENT TRACK FORECAST, WHICH IS CLOSE
TO THE MODEL CONSENSUS. TC 20P SHOULD MAINTAIN INTENSITY OVER THE
NEXT DAY OR SO AS GOOD UPPER LEVEL OUTFLOW COMPETES WITH MODERATE
VERTICAL WIND SHEAR AND PASSAGE OVER COOLER WATER TO INFLUENCE STORM
INTENSITY. THEREAFTER, AN INCREASE IN VERTICAL WIND SHEAR AND A
DECREASE IN POLEWARD OUTFLOW ASSOCIATED WITH THE RIDGE BUILDING TO
THE SOUTH SHOULD RESULT IN SLOW WEAKENING PRIOR TO LANDFALL. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 180000Z IS 21 FEET. NEXT WARNINGS AT
181500Z AND 190300Z.//

REMARKS:
181500Z POSITION NEAR 15.9S 157.4E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 670 NM EAST
OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHWARD AT 02 KNOTS OVER THE
PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS A DECREASE
IN CONVECTION ESPECIALLY IN THE NORTHERN PERIPHERY. INITIAL POSITION
IS BASED ON A SATELLITE IMAGERY FIX FROM PGTW AND INITIAL INTENSITY
IS BASED ON PGTW AND ABRF DVORAK INTENSITY ESTIMATES OF 80 KNOTS.
UPPER LEVEL ANALYSIS INDICATES TC 20P IS LOCATED POLEWARD OF THE
SUBTROPICAL RIDGE (STR) AXIS IN AN AREA OF 20 KNOT VERTICAL WIND
SHEAR (VWS). A MID-LATITUDE TROUGH LOCATED TO THE SOUTHEAST
CONTINUES TO PROVIDE GOOD POLEWARD OUTFLOW. TC 20P IS CURRENTLY
TRACKING SOUTHWARD ON THE WESTERN PERIPHERY OF A NEAR EQUATORIAL
RIDGE. AS A STR BUILDS IN TO THE SOUTH WITHIN THE NEXT 12 HOURS,
ULUI IS EXPECTED TO TURN SOUTHWESTWARD AND BEGIN TO ACCELERATE. TC
20P SHOULD MAKE LANDFALL ON THE NORTHEASTERN QUEENSLAND COAST BY TAU
72 AND THEN WEAKEN SIGNIFICANTLY OVER LAND. VWS SHOULD DECREASE AS
THE STR BUILDS TO THE SOUTH ALLOWING TC 20P TO MAINTAIN CONSTANT
INTENSITIES PRIOR TO LANDFALL. THIS FORECAST IS IN VERY GOOD
AGREEMENT WITH THE PREVIOUS FORECAST AND THE NUMERICAL MODEL
CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 181200Z IS 26 FEET.

REMARKS:
190300Z POSITION NEAR 16.8S 156.3E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY
630 NM EAST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHWESTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS A PARTIALLY EXPOSED LOW LEVEL
CIRCULATION CENTER (LLCC) WITH MINIMAL DEEP CONVECTION
SHEARED TOWARD THE SOUTHEASTERN QUADRANT OF THE SYSTEM.
A 182148Z 37 GHZ TRMM MICROWAVE IMAGE INDICATES A MICROWAVE
EYE WITH SLIGHT EROSION ALONG THE NORTHERN PERIPHERY AND
SPIRAL BANDING WRAPPING INTO THE SYSTEM FROM THE NORTHEAST.
THIS IMAGE AND GOOD AGREEMENT BETWEEN RECENT SATELLITE FIXES
FROM PGTW AND ABRF LEND HIGH CONFIDENCE TO THE CURRENT
POSITION. THE INTENSITY IS CONSISTENT WITH DVORAK CURRENT
INTENSITY ESTIMATES OF 65 KNOTS FROM PGTW, ABRF, AND KNES.
UPPER LEVEL ANALYSIS INDICATES THAT THE SYSTEM IS IN A
REGION OF MODERATE VERTICAL WIND SHEAR INDUCED BY THE
PERIPHERAL FLOW AROUND AN UPPER LEVEL TROUGH TO THE WEST.
THIS VERTICAL WIND SHEAR HAS INDUCED STEADY WEAKENING OVER
THE PAST 12 HOURS DESPITE GOOD POLEWARD OUTFLOW AHEAD OF A
MIDLATITUDE TROUGH TO THE SOUTHEAST. THE SYSTEM IS FORECAST
TO CONTINUE WEAKENING UNDER THE ONGOING INFLUENCE OF VERTICAL
WIND SHEAR AS IT TRACKS SOUTHWESTWARD TO WESTWARD ALONG THE
PERIPHERY OF A BUILDING SUBTROPICAL RIDGE (STR) TO THE SOUTH
AND EAST. NUMERICAL MODEL GUIDANCE REMAINS IN GOOD AGREEMENT.
THEREFORE THIS FORECAST FAVORS PERSISTENCE AND IS CLOSE TO
CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 190000Z IS
24 FEET. NEXT WARNINGS AT 191500Z AND 200300Z.//

REMARKS:
191500Z POSITION NEAR 18.2S 155.0E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 560 NM EAST
OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 11 KNOTS OVER THE
PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS A
PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH A LOSS IN
DEEP CONVECTION. A 190909Z SSMIS MICROWAVE IMAGE CONFIRMS THE DEEP
CONVECTION IS LIMITED TO THE SOUTHERN PERIPHERY OF THE SYSTEM. THE
INITIAL INTENSITY IS BASED ON PGTW, ABRF, AND KNES DVORAK INTENSITY
ESTIMATES OF 55 KNOTS. AN UPPER LEVEL TROUGH TO THE WEST HAS CAUSED
INCREASED VERTICAL WIND SHEAR (VWS) AND SUBSIDENCE ALOFT, WHICH HAS
CONTRIBUTED TO THE WEAKENING OF TC 20P. ULUI WILL CONTINUE TO TRACK
SOUTHWESTWARD TO WESTWARD TOWARD EASTERN AUSTRALIA AS THE
SUBTROPICAL RIDGE CONTINUES TO BUILD IN TO THE SOUTH AND EAST. TC
20P WILL WEAKEN UNDER THE INFLUENCE OF MODERATE VWS, PRIOR TO
REACHING LAND AFTER TAU 36, WITH COMPLETE DISSIPATION OVER LAND BY
TAU 48. NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT AND THIS
FORECAST IS IN AGREEMENT WITH THE CONSENSUS OF AVAILABLE MODELS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191200Z IS 26 FEET. NEXT WARNINGS
AT 200300Z AND 201500Z.//

REMARKS:
200900Z POSITION NEAR 20.1S 150.9E.
TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 385 NM EAST-
SOUTHEAST OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED MULTISPECTRAL IMAGERY
SHOWS TIGHTLY CURVED BANDING BUILDING FROM THE SOUTHWEST, OUTLINING
AN EASILY IDENTIFIABLE LOW LEVEL CIRCULATION CENTER. THE INITIAL
FORECAST INTENSITY HAS BEEN HELD AT 55 KNOTS IN ACCORDANCE WITH THE
DVORAK CURRENT INTENSITY (CI) ESTIMATE FROM PGTW AND THE MARGINALLY
IMPROVED CONVECTIVE SIGNATURE, PARTICULARLY WITHIN THE NORTHWEST
QUADRANT. THE CYCLONE WILL TRACK JUST SOUTH OF WEST ALONG THE
NORTHERN PERIPHERY OF THE DEEP LAYER STEERING RIDGE TO THE SOUTH AND
MAKE LANDFALL AROUND TAU 12. THE CYCLONE WILL THEN STEADILY
DISSIPATE OVER INTERIOR QUEENSLAND. INCREASED VERTICAL WIND SHEAR
AND COOLER SEA SURFACE TEMPERATURES SHOULD THWART INTENSIFICATION
PRIOR TO LANDFALL. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 200600Z IS 20
FEET. NEXT WARNINGS AT 202100Z AND 210900Z.//

TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 260 NM SOUTH-
EAST OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 16 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
THAT TC 20P HAS MADE LANDFALL INTO NORTHEAST AUSTRALIA AT 1700Z IN
THE VICINITY OF BOWEN, AUSTRALIA. OBSERVATIONS INDICATED WINDS BET-
WEEN 40 TO 50 KNOTS, WITH GUSTS AROUND 55 KNOTS. THE CURRENT INTEN-
SITY OF 45 KNOTS IS BASED ON THESE OBSERVATIONS. THE STEERING RIDGE
WILL CONTINUE TO TRACK ULUI INTO NORTHEASTERN AUSTRALIA, WITH CONT-
INUED WEAKENING, AND DISSIPATION EXPECTED WITHIN THE NEXT 24 HOURS.
A BRIEF PERIOD OF INTENISIFICATION TOOK PLACE PRIOR TO LANDFALL, WITH
A PEAK NEAR 95 KNOTS OBSERVED AT 1240Z ON HAMILTON ISLAND AS TC 20P
TRACKED OVER THE ISLAND. HOWEVER, ULUI QUICKLY BEGAN TO WEAKEN AGAIN
AS THE OUTER BANDS OF THE SYSTEM BEGAN TO MOVE OVER LAND. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVMARFCSTCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION.//
