SUBJ/TROPICAL CYCLONE FORMATION ALERT 040200ZJUN2003//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE 150 NM
EITHER SIDE OF A LINE FROM 9.8S7 173.6E7 TO 11.0S2 167.2E6 WITHIN
THE NEXT 06 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 35 KNOTS. METSAT IMAGERY AT 062330Z4
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 9.9S8 172.0E0.
THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 03 KNOTS.
2. REMARKS: LATEST MULTISPECTRAL SATELLITE IMAGERY INDICATES DEEP
CONVECTION HAS CONTINUED TO ORGANIZE OVER A PARTIALLY EXPOSED LOW
LEVEL CIRCULATION CENTER (LLCC). UPPER-LEVEL ANALYSIS REVEALS
FAVORABLE DIVERGENCE ALOFT AND WEAK TO MODERATE VERTICAL WIND SHEAR
OVER THE AREA. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 06 TO 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
050200Z7.//

TROPICAL CYCLONE (TC) 29P, LOCATED 610 NM EAST OF HONIARA, SOLOMON
ISLANDS, HAS TRACKED WEST-SOUTHWESTWARD AT 05 KNOTS DURING THE PAST
06 HOURS. THE WARNING POSITION IS BASED ON 041730Z5 ENHANCED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS AND A
RECENT QUIKSCAT PASS. RECENT SPECIAL SENSOR MICROWAVE IMAGER (SSM/I)
PASSES REVEAL THAT THE DEEP CONVECTION OVER THE LOW LEVEL
CIRCULATION CENTER (LLCC) HAS WEAKENED SLIGHTLY OVER THE PAST 06
HOURS. TC 29P IS FORECAST TO TRACK SLOWLY WEST-SOUTHWESTWARD UNDER
THE STEERING INFLUENCE OF THE LOW TO MID-LEVEL RIDGE SOUTHEAST OF
THE SYSTEM. INTERACTION BETWEEN 29P AND ANOTHER WEAK CIRCULATION TO
THE WEST-NORTHWEST OF THE SYSTEM IS LIKELY, GIVING A SLIGHT
EQUATORWARD BIAS TO THE TRACK. THE AVAILABLE DYNAMIC AIDS INCLUDING
NOGAPS, NCEP GFS AND UKMET GLOBAL (EGRR) ARE IN GOOD AGREEMENT WITH
THIS FORECAST. THIS FORECAST IS BASED ON PERSISTENCE AND A CONSENSUS
OF THE AVAILABLE DYNAMIC AIDS. TC 29P IS FORECAST TO INTENSIFY AT A
LESS THAN CLIMATOLOGICAL RATE IN A MODERATE UPPER LEVEL ENVIRONMENT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z3 IS 12 FEET. THIS WARNING

AT 09 KNOTS DURING THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 062330Z4 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 77 AND 90
KNOTS. ANIMATED MULTISPECTRAL AND ENHANCED INFRARED SATELLITE
IMAGERY INDICATES THAT TC 29P HAS DEVELOPED A WELL-DEFINED EYE OVER
THE LAST 06 HOURS. THE SYSTEM CONTIUES TO TRACK ALONG THE WESTERN
PERIPHERY OF A MID-LEVEL RIDGE TO THE EAST OF THE SYSTEM, IN A
REGION OF FAVORABLE UPPER-LEVEL DIVERGENCE, ALLOWING FOR MORE RAPID
INTENSIFICATION THAN PREVIOUSLY FORECAST. AN APPROACHING MID-
LATITUDE TROUGH IS EXPECTED TO CREATE A WEAKNESS IN THE LOW TO MID-
LEVEL RIDGE POLEWARD OF THE SYSTEM ALLOWING TC 29P TO TRACK MORE
POLEWARD AFTER 12 HOURS. AT THE 24 TO 36 HOUR TIMEFRAME, THE MID-
LATITUDE TROUGH WILL HAVE PROPAGATED EASTWARD, IN RESPONSE TO A
BUILDING RIDGE NOW OVER SOUTHERN AUSTRALIA. INTERACTION BETWEEN TC
29P AND THIS RIDGE WILL INCREASE THE MID-LEVEL WESTERLY GRADIENT,
WEAKENING THE SYSTEM. THE AVAILABLE DYNAMIC AIDS INCLUDING NOGAPS,
NCEP GFS, GFDN, AFWA MM5, AND UKMET GLOBAL (EGRR) REMAIN WIDELY
DISPARATE, WITH NOGAPS, NCEP GFS, AND AFWA MM5 INTERACTING TC 29P

070530Z5 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 KNOTS. TC
29P CONTINUES TO TRACK POLEWARD AROUND THE WESTERN EDGE OF A MID-
LEVEL RIDGE TO THE EAST OF THE SYSTEM. TC 29P WILL LINK UP WITH A
MAJOR SHORTWAVE CURRENTLY EXITING SOUTHEAST AUSTRALIA AND RECURVE TO
THE SOUTHEAST MID-WAY THROUGH THE FORECAST PERIOD. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY INDICATES THAT TC 29P'S EYE HAS BECOME
MORE RAGGED AND LESS WELL-DEFINED IN THE LAST 06 HOURS. ANALYSIS OF
UW-CIMMS DATA SHOWS THAT TC 29P HAS TRANSITIONED INTO AN ENVIRONMENT
OF INCREASING SHEAR AND WILL EVENTUALLY ENCOUNTER COOLER SEA SURFACE
TEMPERATURES NEAR THE END OF THE FORECAST PERIOD. THE AVAILABLE
DYNAMIC AIDS INCLUDING NOGAPS, NCEP GFS, AFWA MM5, AUSTRALIAN TLAPS,
AND UKMET GLOBAL (EGRR) REMAIN IN VERY POOR AGREEMENT. NOGAPS
CONTINUES TO INTERACT TC 29P EXCESSIVELY WITH A CIRCULATION NEAR THE
SOLOMON ISLANDS. ANALYSIS OF THE NCEP GFS INDICATES POSSIBLE TRACKER
ALGORITHM PROBLEMS. EGGR IS THE MOST REASONABLE OF THE DYNAMIC
MODELS FOR THIS FORECAST SCENARIO. EGGR'S SOLUTION BEST MATCHES
PERSISTENCE AND THE EXPECTED EFFECTS OF THE APPROACHING SHORTWAVE
FROM THE SOUTHWEST. EGGR'S RECURVATURE SOLUTION IS ALSO MATCHED AND
SUPPORTED TO SOME DEGREE BY SBAM, MBAM, AND THE STATISTICAL AND
CLIMATOLOGICAL AIDS OF CLIM AND CLIP. THIS FORECAST IS BASED ON
PERSISTENCE AND HEAVY EMPHASIS ON EGRR'S SOLUTION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071200Z IS 16 FEET. NEXT WARNINGS AT
080300Z1 AND 081500Z4.//

REMARKS:
080300Z1 POSITION NEAR 17.6S4 161.9E7.
TROPICAL CYCLONE (TC) 29P, LOCATED APPROXIMATELY 390 NM NORTHWEST OF
NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT 03 KNOTS
DURING THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON 072330Z5
MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 90 AND 105 KNOTS. TC 29P
HAS MADE THE TURN POLEWARD AROUND THE WESTERN EDGE OF A MID-LEVEL
RIDGE EAST OF THE SYSTEM. TC 29P IS EXPERIENCING SHEAR IN THE
SOUTHWEST SECTOR ASSOCIATED WITH A MID-LATITUDE SHORTWAVE TROUGH NOW
SOUTHWEST OF THE SYSTEM. TC 29P WILL ULTIMATELY LINK WITH THIS
TROUGH AND BEGIN THE TRANSITION TO AN EXTRATROPICAL SYSTEM. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, NCEP GFS, AFWA MM5, AND
UKMET (EGRR) ARE NOW IN REASONABLE AGREEMENT WITH THIS SCENARIO,
WITH THE EXCEPTION OF AFWA MM5 WHICH PROGS THE SYSTEM IN A LESS THAN
LIKELY TRACK WESTWARD TOWARD AUSTRALIA. THIS FORECAST IS BASED ON A
CONSENSUS OF THE DYNAMIC MODELS, LESS AFWA MM5. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 080000Z8 IS 16 FEET. NEXT WARNINGS AT 081500Z4 AND 090300Z2.//

REMARKS:
081500Z4 POSITION NEAR 18.7S6 164.0E1.
TROPICAL CYCLONE (TC) 29P, LOCATED APPROXIMATELY 300 NM NORTHWEST OF
NOUMEA, NEW CALEDONIA, HAS TRACKED EAST-SOUTHEASTWARD AT 13 KNOTS
DURING THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON 081130Z3
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 65 KNOTS. TC 29P HAS
LINKED UP WITH A MAJOR SHORTWAVE TROUGH TO THE SOUTH AND IS NOW
RECURVING RAPIDLY TO THE EAST-SOUTHEAST. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY REVEALS THAT MOST OF THE CONVECTION HAS BEEN
SHEARED FROM SYSTEM LEAVING AN EXPOSED LOW LEVEL CIRCULATION CENTER.
TC 29P IS EXPECTED TO CONTINUE RECURVING TO THE EAST-SOUTHEAST IN
THE MID-LAT WESTERLIES AND COMPLETE EXTRATROPICAL TRANSITION IN 24
HOURS. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, NCEP GFS,
AFWA MM5, AND THE AUSTRALIAN TLAPS AND TCLAPS ARE IN POOR AGREEMENT
WITH THIS SCENARIO. AFWA MM5 AND TLAPS CONTINUE TO HAVE TC 29P TRACK
NORTHWESTWARD DUE TO PROBABLE EXCESSIVE INTERACTION WITH A WEAK
CIRCULATION IN THE SOLOMON ISLANDS. NCEP GFS, TCLAPS, AND MANY OF
THE STATISTICAL AND CLIMO AIDS SUPPORT RECURVATURE WHICH IS WHAT
PERSISTENCE AND THE METEOROLOGICAL PATTERN SUGGEST. THE NOGAPS AID
(NGPI) ALSO SHOWS A SOLUTION TO THE NORTHWEST SIMILAR TO AFWA BUT A
CLOSER ANALYSIS OF THE FIELDS REVEALS THAT THE VORTEX RECURVES. THIS
FORECAST IS BASED ON A CONSENSUS OF THE DYNAMIC MODELS WITH LESS
EMPHASIS ON AFWA MM5 AND TLAPS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
081200Z1 IS 14 FEET. NEXT WARNINGS AT 090300Z2.//

TROPICAL CYCLONE (TC) 29P, LOCATED APPROXIMATELY 225 NM NORTH-
NORTHWEST OF NOUMEA, NEW CALEDONIA, HAS TRACKED EAST-SOUTHEASTWARD
AT 17 KNOTS DURING THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 081730Z9 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55
AND 65 KNOTS. TC 29P HAS LINKED WITH A DEEP MID-LATITUDE TROUGH TO
THE SOUTH AND IS NOW TRACKING RAPIDLY TO THE EAST-SOUTHEAST AS AN
EXTRATROPICAL SYSTEM. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
NOGAPS AND NCEP GFS ARE IN CLOSE AGREEMENT WITH A FAST-PACED TRACK
TAKING THE EXTRATROPICAL REMNANTS OF 29P POLEWARD. UKMET (EGRR) NOW
DISSIPATES THE SYSTEM IN PLACE NORTHWEST OF NEW CALEDONIA, AND IS
NOT CONSIDERED IN THIS FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
081800Z7 IS 14 FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE
JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE
CLOSELY MONITORED FOR SIGNS OF REGENERATION.//
