SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 13.1S 179.4W TO 17.4S 176.4W
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNING AT THIS TIME. WINDS
IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT
261800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 13.2S
179.3W. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 07 KNOTS.
2. REMARKS: RECENT METSAT IMAGERY SHOWS LOW TO MID LEVEL CYCLONIC
TURNING WITH PERSISTENT CONVECTIVE BANDING WRAPPING INTO THE CENTER.
THE UPPER LEVEL ENVIRONMENT CONTINUES TO BE FAVORABLE FOR DEVELOPMENT
WITH LOW VERTICAL WIND SHEAR, AN UPPER LEVEL ANTICYCLONE AND GOOD
EQUATORWARD AND POLEWARD OUTFLOW OVER THE DISTURBANCE. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. DUE TO IMPROVED
UPPER LEVEL ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED
TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
272230Z.//

REMARKS:
272100Z POSITION NEAR 15.8S 179.7W.
TROPICAL CYCLONE (TC) 15P (NONAME) LOCATED APPROXIMATELY 210 NM
NORTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHWESTWARD AT 04 KNOTS
OVER THE PAST 06 HOURS. RECENT METSAT IMAGERY AND INTENSITY
ESTIMATES FROM PGTW INDICATE THE SYSTEM HAS NOW REACHED SIGNIFICANT
TROPICAL CYCLONE STRENGTH. THE UPPER LEVEL ENVIRONMENT REMAINS
FAVORABLE FOR FURTHER DEVELOPMENT WITH AN ANTICYCLONE ALOFT,
GOOD EQUATORIAL OUTFLOW AND WEAK POLEWARD OUTFLOW. THE SYSTEM IS
EXPECTED TO INTERACT WITH THE FIJI ISLANDS PRIOR TO TAU 12. THE
INTERACTION WITH THE ISLANDS WILL LIMIT INTENSIFICATION BUT THE
FAVORABLE UPPER LEVEL ENVIRONMENT WILL PREVENT THE STORM FROM
WEAKENING. AROUND TAU 24, THE STORM WILL BE POLEWARD OF THE FIJI
ISLANDS AND OVER FAVORABLE WARM WATERS. BY THIS TIME, THE SUBTROPICAL
RIDGE WILL HAVE BUILT IN SOUTH OF THE SYSTEM, SHIFTING THE TRACK
TO WESTWARD FOR THE REST OF THE FORECAST PERIOD. OVERALL, THE
AVAILABLE DYNAMICIAL AIDS WERE IN GOOD AGREEMENT WITH THE FORECAST.

REMARKS:
280900Z POSITION NEAR 17.6S 178.1E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 95 NM
NORTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHWESTWARD AT 09 KNOTS
OVER THE PAST 06 HOURS. RECENT MULTISPECTRAL IMAGERY CONTINUES
TO SHOW A WELL ORGANIZED LOW LEVEL CIRCULATION CENTER (LLCC) DESPITE
LAND INTERACTION WITH FIJI. A SSMI 280728Z 85 GHZ MICROWAVE
PASS ALSO SHOWS DEEP CONVECTION OVER THE LLLC. UPPER LEVEL
ANALYSIS INDICATES GOOD EQUATORWARD, BUT LIMITED POLEWARD OUTFLOW
ASSOCIATED WITH THE SYSTEM. THE STORM IS EXPECTED TO TRACK WEST-
SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY OF THE SUBTROPICAL
RIDGE TOWARD AN AREA OF SLIGHTLY LOWER OCEAN HEAT CONTENT (OHC).
ONLY A GRADUAL INTENSIFICATION IS EXPECTED THROUGHOUT THE
FORECAST PERIOD DUE TO THE LOWER OHC VALUES AND CONTINUED
LACK OF A POLEWARD OUTFLOW CHANNEL. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 280600Z IS 15 FEET. NEXT WARNINGS AT 282100Z AND
290900Z. JUSTIFICATION FOR CORRECTION: REMOVED REFERENCE TO

REMARKS:
282100Z POSITION NEAR 17.9S 175.5E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 85 NM WEST OF
NADI, FIJI, HAS TRACKED WEST-SOUTHWESTWARD AT 10 KNOTS OVER THE PAST
06 HOURS. ANIMATED INFRARED SATELLITE IMAGERY, NADI RADAR DATA AND A
281315Z AMSR-E IMAGE SUPPORT A MORE WESTWARD TRACK THAN THE PREVIOUS
FORECAST INDICATED. IMAGERY SHOWS THAT THE SYSTEM IS LOCATED ON THE
NORTHERN EDGE OF THE DEEP CONVECTION WITH WEAK CONVECTIVE BANDING
EAST WRAPPING INTO THE SOUTHWESTERN QUADRANT. UPPER-LEVEL OUTFLOW
REMAINS GOOD OVERALL WITH EQUATORWARD OUTFLOW ENHANCED BY AN UPPER-
LOW NEAR 10S 155W, HOWEVER, POLEWARD FLOW IS RESTRICTED DUE TO
CONVERGENT FLOW SOUTH OF THE SYSTEM. THIS FACTOR COMBINED WITH LAND
INTERACTION HAVE SERVED TO DISRUPT FURTHER CONSOLIDATION OVER THE
PAST 12 HOURS. DVORAK INTENSITY ESTIMATES HAVE DECREASED SLIGHTLY
BUT CURRENTLY RANGE FROM 35 TO 55 KNOTS. THE CURRENT INTENSITY IS
BASED ON AN AVERAGE OF THE ESTIMATES PLUS RECENT SYNOPTIC OBSERV-
ATIONS FROM NADI INDICATING SUSTAINED SURFACE WINDS AT 35 KNOTS AND
GUSTS TO 45 KNOTS OVER THE PAST 06 HOURS. DESPITE THE NORTHWARD
SHIFT IN THE FORECAST TRACK, THE TRACK PHILOSOPHY IS LARGELY UN-
CHANGED WITH THE SYSTEM STEERING ALONG THE NORTHERN PERIPHERY OF
THE SUBTROPICAL RIDGE (STR). THE STR IS FORECAST TO WEAKEN AFTER
TAU 24, THEREFORE, THE TRACK SPEEDS REFLECT A SLIGHT DECREASE FROM
CURRENT SPEEDS. TC 15P IS FORECAST TO DEVELOP SLOWLY AND SHOULD
EVENTUALLY TAP INTO THE MIDLATITUDE WESTERLIES, IMPROVING
POLEWARD OUTFLOW AND ALLOWING THE SYSTEM TO INTENSIFY UP TO 60
KNOTS BY TAU 48. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 281800Z IS
15 FEET. NEXT WARNINGS AT 290900Z AND 292100Z.//

REMARKS:
290900Z POSITION NEAR 18.6S 174.7E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 140 NM WEST-
SOUTHWEST OF NADI, FIJI, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS OVER
THE PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY, AND A
290203Z MICROWAVE IMAGE IMAGERY SHOW THAT THE SYSTEM IS LOCATED ON
THE WESTERN EDGE OF THE DEEP CONVECTION WITH WEAK CONVECTIVE BANDING
WRAPPING INTO THE SOUTHWESTERN QUADRANT. UPPER LEVEL ANALYSIS REV-
EALS GOOD OUTFLOW ASSOCIATED WITH AN ANTICYCLONE ALOFT WHICH IS
EXPECTED TO AID IN GRADUAL INTENSIFICATION FOR THE REMAINDER OF THE
FORECAST PERIOD. DVORAK INTENSITY ESTIMATES HAVE REMAINED CONSISTENT
RANGING FROM 35 TO 55 KNOTS AND SUPPORT THE CURRENT INTENSITY OF THE
SYSTEM. DESPITE THE SLIGHT SOUTHWARD SHIFT IN THE FORECAST TRACK,
THE TRACK PHILOSOPHY IS LARGELY UNCHANGED FROM THE PREVIOUS FORECAST
WITH THE SYSTEM STEERING ALONG THE NORTHERN PERIPHERY OF THE SUB-
TROPICAL RIDGE (STR). THE FORECAST, WHICH CALLS FOR SLOW DEVELOPMENT

REMARKS:
292100Z POSITION NEAR 18.6S 173.5E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 480 NM EAST-
NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED WESTWARD AT 06 KNOTS
OVER THE PAST 06 HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
IMPROVED OVERALL CONSOLIDATION AND STRONGER DEEP CONVECTIVE BANDING
OVER THE EASTERN SEMI-CIRCLE. A 291719Z SSMI IMAGE SHOWS A LARGE
BANDING EYE WITH THE MAJORITY OF THE INTENSE CONVECTION EAST OF THE
CENTER. ANIMATED WATER VAPOR IMAGERY INDICATES THAT OUTFLOW HAS
IMPROVED DUE TO AN UPPER-LOW NEAR 10S 157W (ENHANCING EQUATORWARD
OUTFLOW) AND ANOTHER LOW/TROUGH NEAR 30S 177W (ENHANCING POLEWARD
OUTFLOW). THE CURRENT INTENSITY IS BASED ON AN AVERAGE OF DVORAK
ESTIMATES RANGING FROM 45 TO 55 KNOTS. TC 15P CONTINUES TO TRACK
ALONG THE NORTHERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL
RIDGE AND IS FORECAST TO REMAIN ON THIS TRACK THROUGH TAU 24 THEN
WILL TRACK INCREASINGLY SOUTHWESTWARD TOWARD A WEAKNESS IN THE
RIDGE WHICH IS FORECAST TO DEVELOP WITH THE APPROACH OF A MID-
LATITUDE TROUGH. THE STRENGTH AND TIMING OF THIS TROUGH WILL
DETERMINE THE RECURVATURE POINT. THEREFORE, THE DYNAMIC MODELS
ARE IN GOOD AGREEMENT THROUGH TAU 24 BUT DIVERGE WITH EGRR THE
WESTERN-MOST SOLUTION AND NOGAPS THE EASTERN-MOST SOLUTION. THIS
FORECAST IS BASED ON THE CONSENSUS BUT IS SLIGHTLY FASTER AND
RIGHT OF THE CONSENSUS AT TAU 36 AND 48. TC 15P IS FORECAST TO
INTENSIFY AT 5-10 KNOTS PER DAY DUE TO THE MARGINAL OCEAN HEAT
CONTENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 291800Z IS 20 FEET.

REMARKS:
300900Z POSITION NEAR 18.8S 172.4E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 415 NM EAST-
NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED WESTWARD AT 06 KNOTS
OVER THE PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND
A 300209Z AMSR-E IMAGE DEPICT GOOD CONSOLIDATION AND STRONG DEEP CON-
VECTIVE BANDING SURROUNDING A WELL DEFINED BANDING EYE WITH THE
MAJORITY OF THE INTENSE CONVECTION EAST OF THE CENTER. ANIMATED WATER
VAPOR IMAGERY SHOWS EVIDENCE OF CONTINUED GOOD UPPER-LEVEL OUTFLOW.
THE CURRENT INTENSITY IS BASED ON AN AVERAGE OF DVORAK ESTIMATES
RANGING FROM 50 TO 77 KNOTS. TC 15P CONTINUES TO TRACK ALONG THE NOR-
THERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE AND IS
FORECAST TO REMAIN ON THIS TRACK THROUGH TAU 24 AND THEN WILL TRACK
INCREASINGLY SOUTHWESTWARD TOWARD A WEAKNESS IN THE RIDGE WHICH IS
FORECAST TO DEVELOP WITH THE APPROACH OF A MIDLATITUDE TROUGH. THE
DYNAMIC MODELS ARE IN GOOD AGREEMENT THROUGH TAU 24 BUT DIVERGE WITH
EGRR AS THE WESTERN-MOST SOLUTION AND GFDN AS THE EASTERN-MOST SOLU-
TION. DUE TO MARGINAL OCEAN HEAT CONTENT, TC 15P IS FORECAST TO INT-
ENSIFY GRADUALLY REACHING AN INTENSITY OF 65 KNOTS AT THE END OF THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 300600Z IS 24
FEET. NEXT WARNINGS AT 302100Z AND 310900Z.

REMARKS:
302100Z POSITION NEAR 19.1S 171.7E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 370 NM EAST-
NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED WEST-SOUTHWESTWARD AT
06 KNOTS OVER THE PAST 06 HOURS. RECENT METSAT IMAGERY AND INTENSITY
ESTIMATES FROM PGTW, KNES, AND ABRF INDICATE THE SYSTEM HAS STRENGTHENED
SIGNIFICANTLY SINCE THE LAST WARNING. MICROWAVE IMAGERY DEPICTS A WELL
DEFINED EYE FEATURE WITH CONVECTIVE BANDS WRAPPING IN ALONG THE SOUTHERN
PERIPHERY OF THE SYSTEM. ANIMATED WATER VAPOR IMAGERY SHOWS EVIDENCE OF
CONTINUED GOOD EQUATORWARD OUTFLOW. TC 15P CONTINUES TO TRACK ALONG THE
NORTHWESTERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE AND
IS FORECAST TO TAKE ON A SOUTHWESTWARD TRACK AFTER TAU 12. THIS SOUTH-
WESTWARD TRACK IS DUE TO A DEVELOPING WEAKNESS IN THE RIDGE CAUSED BY
AN APPROACHING MIDLATITUDE TROUGH. AS THE MIDLATITUDE TROUGH APPROACHES
FROM THE WEST, IT WILL ALLOW FOR AN INCREASE IN POLEWARD OUTFLOW AND
FURTHER STRENGTHEN 15P. THE FORECAST IS IN GOOD AGREEMENT WITH THE
DYNAMICAL AIDS. THE FORECAST INTENSITY HAS BEEN INCREASED SIGNIFICANTLY
SINCE THE LAST FORECAST DUE TO BETTER THAN EXPECTED UPPER LEVEL EN-
VIRONMENT. THE FORECAST TRACK HAS ALSO SHIFTED TO MORE OF A SOUTHWEST-
WARD TRACK WHICH IS ALSO INDICATED BY THE DYNAMIC AIDS. MAXIMUM SIGN-
IFICANT WAVE HEIGHT AT 301800Z IS 30 FEET. NEXT WARNINGS AT 310900Z AND

REMARKS:
010900Z POSITION NEAR 20.3S 170.7E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 270 NM EAST-
NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTHEASTWARD AT 03
KNOTS OVER THE PAST 06 HOURS. RECENT INFRARED ANIMATED IMAGERY SHOWS A
MATURE SYSTEM WITH A BANDING EYE AND GOOD EQUATORWARD OUTFLOW. A
012149Z 85 GHZ TRMM MICROWAVE PASS REVEALS AN AREA OF DEEP CONVECTION
IN THE NORTHEAST AND SOUTHEAST QUADRANTS WRAPPING INTO THE LLCC. THE
37 GHZ IMAGE FROM THE SAME MICROWAVE PASS SHOWS THAT THE LOW LEVEL IS
APPROXIMATELY HALF A DEGREE TO THE EAST OF THE DISCERNABLE UPPER LEVEL
CENTER. THIS DISPLACEMENT BETWEEN LEVELS SUGGESTS THAT THE SYSTEM IS
CURRENTLY ENCOUNTERING HIGHER SHEAR VALUES AND WILL ACCOUNT FOR
MARGINALLY LOWER INTENSITIES THAN PREVIOUSLY FORECASTED. THE SYSTEM
WILL CONTINUE TO TRACK POLEWARD ALONG THE NORTHWESTERN PERIPHERY OF
THE SUBTROPICAL RIDGE. BROAD RIDGING TO THE SOUTH OF THE SYSTEM WILL
ACT TO STEER THE SYSTEM ON MORE OF AN INITIAL SOUTH-SOUTHWESTWARD TRACK
UNTIL THE RIDGE BREAKS DOWN AROUND TAU 12. OBJECTIVE MODEL AIDS HAVE
SHIFTED EAST OVER THE PAST 24 HOURS AND THE CURRENT FORECAST POSITION
REFLECTS THAT SHIFT. NEXT WARNINGS AT 011500Z AND 020300Z. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 010600Z IS 33 FEET. NEXT WARNINGS AT 012100Z

SOUTH-SOUTHEASTWARD AT 10 KNOTS OVER THE PAST 06 HOURS.
RECENT INFRARED AND WATER VAPOR SATELLITE IMAGERY DEPICTS
A SLIGHT INCREASE IN DEEP CONVECTION OVER THE PAST 06 HOURS,
BUT THE OVERALL ORGANIZATION OF THE STORM REMAINS UNCHANGED
FROM 12 HOURS AGO. THEREFORE THE INTENSITY OF 55 KNOTS FROM
12 HOURS AGO HAS BEEN MAINTAINED. THIS IS DUE TO A SLIGHT
DECREASE IN VERTICAL WIND SHEAR AND GOOD UPPER LEVEL OUTFLOW
TO THE EAST. THE STORM WILL BEGIN SLOWLY WEAKENING OVER THE
NEXT 06 HOURS, AS IT BEGINS TO PASS OVER COOLER SEA SURFACE
TEMPERATURES AND IT BEGINS TO ENCOUNTER HIGHER VERTICAL WIND
SHEAR DUE TO INTERACTION WITH THE MIDLATITUDE WESTERLIES.
TC 15P WILL BEGIN TO TRACK MORE SOUTHEASTWARD THROUGH THE
FORECAST PERIOD. EXTRATROPICAL TRANSITION IS EXPECTED TO
BEGIN BY TAU 24 AND THE STORM WILL BE FULLY EXTRATROPICAL
PRIOR TO TAU 48. THE STORM WILL SLOWLY ACCELERATE AS IT
BEGINS AND THEN COMPLETES EXTRATROPICAL TRANSITION. THE

REMARKS:
040900Z POSITION NEAR 27.7S 174.0E.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 495 NM SOUTH-
EAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 13
KNOTS OVER THE PAST 06 HOURS. RECENT MULTISPECTRAL AND WATER VAPOR
SATELLITE IMAGERY DEPICT GOOD ORGANIZATION OF THE STORM, HOWEVER DEEP
CONVECTION HAS BEGUN TO GRADUALLY ABATE OVER THE PREVIOUS 12 HOURS.
THE INTENSITY OF 55 KNOTS IS SUPPORTED BY MULTIPLE AGENCY DVORAK
ESTIMATES RANGING FROM 45 TO 55 KNOTS AND RECENT SCATTEROMETRY OBSER-
VATIONS. THE STORM IS EXPECTED TO CONTINUE WEAKENING OVER THE FORE-
CAST PERIOD AS IT TRACKS EAST-SOUTHEASTWARD MOVING INTO AN AREA OF
COOLER SEA SURFACE TEMPERATURES AND HIGHER VERTICAL WIND SHEAR ASSOC-
IATED WITH THE MIDLATITUDE WESTERLIES. EXTRATROPICAL TRANSITION IS
EXPECTED NEAR TAU 24 AND THE STORM WILL BE FULLY EXTRATROPICAL PRIOR
TO TAU 48. THE STORM WILL SLOWLY ACCELERATE AS IT BEGINS AND THEN
COMPLETES EXTRATROPICAL TRANSITION. THE FORECAST IS BASED ON THE CON-
SENSUS OF AVAILABLE OBJECTIVE AIDS, WHICH REMAIN IN GOOD AGREEMENT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040600Z IS 17 FEET.
NEXT WARNINGS AT 042100Z AND 050900Z.

TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 570 NM SOUTH-
EAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED EAST-SOUTHEASTWARD AT 08
KNOTS OVER THE PAST 06 HOURS. RECENT INFRARED AND WATER VAPOR SATELL-
ITE IMAGERY DEPICT RAPIDLY DECAYING DEEP CONVECTION WITH NO SIGNIFI-
CANT CONVECTION NEAR THE CENTER. A 041818Z SSMI IMAGE SHOWS A WELL-
DEFINED, TIGHTLY-WRAPPED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
WEAK CONVECTION TWO DEGREES SOUTH. A 040939Z ASCAT IMAGE INDICATED
40-45 KNOT UNFLAGGED WINDS NEAR THE CENTER. SATELLITE IMAGERY AND
UPPER AIR ANALYSES INDICATE THAT THE SYSTEM HAS BEGUN TO INTERACT
WITH A MIDLATITUDE TROUGH AND HAS CLEARLY STARTED TO UNDERGO EXTRA-
TROPICAL TRANSITION (ETT) AS IT TRACKS POLEWARD OF THE SUBTROPICAL
RIDGE AXIS. THEREFORE, THE CURRENT FORECAST REFLECTS A FASTER ETT
THAN THE PREVIOUS FORECAST INDICATED WITH TC 15P EXPECTED TO COM-
PLETE ETT BY TAU 24. THE CURRENT INTENSITY OF 45 KNOTS IS SUPPORTED
BY MULTIPLE AGENCY DVORAK ESTIMATES RANGING FROM 35 TO 55 KNOTS AND
RECENT SCATTEROMETRY OBSERVATIONS. TC 15P IS FORECAST TO TRACK EAST-
SOUTHEASTWARD OVER VERY COOL SST (NEAR 24C) UNDER HIGHER SHEAR

052100Z POSITION NEAR 28.5S 179.2W.
TROPICAL CYCLONE (TC) 15P (GENE) LOCATED APPROXIMATELY 590 NM NORTH-
NORTHEAST OF AUCKLAND, NEW ZEALAND, HAS TRACKED EASTWARD AT 11 KNOTS
OVER THE PAST 06 HOURS. RECENT ANIMATED INFRARED IMAGERY AND A
051803Z SSMI IMAGE DEPICT A DEFINED, BROADENING LOW-LEVEL CIRCUL-
ATION CENTER (LLCC) WITH PERSISTENT DEEP CONVECTION OVER THE NORTH-
EASTERN QUADRANT. COLD AIR STRATOCUMULUS CONTINUES TO WRAP INTO THE
NORTHERN PERIPHERY OF THE SYSTEM, HOWEVER, THERE IS NO EVIDENCE THAT
THIS DRIER, COOLER AIR IS ENTRAINING INTO THE SYSTEM CORE, AND THE
TPW AND AMSU PRODUCTS CONTINUE TO SHOW A CORE OF WARM, MOIST AIR
SURROUNDING THE CENTER. THE CURRENT INTENSITY IS BASED ON A 050529Z
QUIKSCAT IMAGE WHICH INDICATES 40 TO 45 KNOT WINDS NEAR THE CENTER.
DVORAK INTENSITY ESTIMATES HAVE DECREASED TO 35 KNOTS BUT APPEAR TO
BE TOO LOW DUE TO THE LIMITED DEEP CONVECTION. UPPER AIR ANALYSIS
CONTINUES TO INDICATE THAT THE SYSTEM IS INTERACTING WITH A MID-
LATITUDE TROUGH AND IS UNDERGOING EXTRATROPICAL TRANSITION (ETT).
THIS TRANSITION WILL BE COMPLETE BETWEEN TAU 12 AND 24. ETT HAS
BEEN SLOW WITH THE SYSTEM TRACKING ALONG THE NORTHERN EDGE OF THE
BAROCLINIC ZONE UNDER WEAK MIDLATITUDE WESTERLY FLOW BUT TC 15P IS
EXPECTED TO COMPLETE ETT BETWEEN TAU 12 AND 24. THE DYNAMIC
MODELS ARE IN GOOD AGREEMENT ON TRACK AND INDICATE THAT THE SYSTEM
WILL BECOME EMBEDDED IN THE BAROCLINIC ZONE AFTER TAU 12 AND WILL
BE FULLY CAPTURED BY THE MIDLATIUDE TROUGH. TC 15P WILL CONTINUE
TRACKING EASTWARD OVER VERY COOL SST (NEAR 24C). THIS FORECAST
IS BASED ON THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 051800Z IS 18 FEET. NEXT WARNINGS AT 060900Z.//
