(1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED
NEAR 7.5N 135.5E IS NOW LOCATED NEAR 6.7N 132.8E, APPROXIMATELY 114
NM SOUTHWEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND
A 082125Z SSMIS 91GHZ IMAGE DEPICT AN EXPOSED LOW LEVEL CIRCULATION
WITH FLARING CONVECTION DISPLACED TO THE SOUTHEAST. INVEST 95W IS IN
A FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH LOW (<15 KTS)
VERTICAL WIND SHEAR, GOOD EQUATORWARD OUTFLOW ALOFT AND WARM (28-
30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT
INVEST 95W WILL CONTINUE TO TRACK WESTWARD BEFORE TURNING
NORTHWESTWARD AND INTENSIFYING. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 7.2N 131.7E TO 9.9N 129.0E
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 18 TO 23 KNOTS. METSAT
IMAGERY AT 100000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.2N 131.5E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 05
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED
NEAR 6.7N 132.8E IS NOW LOCATED NEAR 7.2N 131.5E, APPROXIMATELY 180
NM WEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A
092102Z NOAA-19 89GHZ SATELLITE IMAGE DEPICT AN OBSCURED LOW LEVEL
CIRCULATION WITH SOME CONVECTION OVERHEAD AND WEAK FORMATIVE BANDING
TO THE NORTH. INVEST 95W IS IN A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH LOW (<15 KTS) VERTICAL WIND SHEAR, WARM (28-30C)
SEA SURFACE TEMPERATURES, AND GOOD EQUATORWARD OUTFLOW. GLOBAL
MODELS ARE IN AGREEMENT THAT INVEST 95W WILL CONTINUE TO INTENSIFY
WHILE IT TRACKS NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1005 MB. 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
110300Z.
