MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT/072021ZJAN2006//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
210 NM EITHER SIDE OF A LINE FROM 15.0S 175.9W TO 21.0S 169.2W
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 IM
AGERY AT 121730Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 16.3S 174.2W.  THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 18
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.8S
175.7W, IS NOW LOCATED NEAR 16.2S 174.2W, APPROXIMATELY 240 NM WEST-
SOUTHWEST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY INDICATES IMPROVED DEEP CONVECTION ASSOCIATED WITH
A LOW LEVEL CIRCULATION CENTER DEPICTED IN THE 120831Z SSMIS
MICROWAVE PASS. LOCAL SURFACE OBSERVATIONS VERIFY SURFACE WINDS IN
THE VICINITY OF 15 TO 20 KNOTS. UPPER LEVEL ANALYSIS INDICATES THE
SYSTEM HAS MOVED INTO AN ENVIRONMENT OF LIGHT VERTICAL WIND SHEAR
WITH FAVORABLE DIVERGENCE ALOFT WITH A GRADIENT OF INCREASED
VERTICAL SHEAR TO THE SOUTH. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1000 MB. DUE TO IMPROVED DEEP CONVECTION AND ORGANIZATION
THE POTENTIAL FOR THE 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
132000Z.//

REMARKS:
140300Z POSITION NEAR 29.1S 166.9W.
TROPICAL CYCLONE (TC) 06P (TAM), LOCATED APPROXIMATELY 560 NM
SOUTHWEST OF RAROTONGA, HAS TRACKED RAPIDLY SOUTH-SOUTHEASTWARD
AT 40 KNOTS OVER THE PAST 06 HOURS. INCREASING VERTICAL WIND
SHEAR, DECREASING SEA SURFACE TEMPERATURE, CONVERGENCE ALOFT AND
VERY FAST FORWARD SPEED HAVE CAUSED TC 06P TO WEAKEN SIGNIFICANTLY
OVER THE PAST 06 HOURS. TC 06P IS FORECAST TO DISSIPATE OVER WATER
WITHIN THE NEXT 12 HOURS. 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. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 140000Z IS 5 FEET.//
