AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 082030)//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 10.3S4 138.6E8 TO 13.2S6
133.9E6 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 20 TO 30 KNOTS.
METSAT IMAGERY AT 091430Z7 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 10.5S6 137.5E6. THE SYSTEM IS QUASI-STATIONARY AT
00 KNOTS.
3. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.0S2 136.7E7 IS NOW
LOCATED NEAR 10.5S6 137.5E6 IN THE ARAFURA SEA, APPROXIMATELY 410 NM
EAST-NORTHEAST OF DARWIN, AUSTRALIA. ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS IMPROVED ORGANIZATION OVER THE PAST 8 HOURS WITH A
DEVELOPING CONVECTIVE BAND EAST OF THE LOW-LEVEL CIRCULATION CENTER
(LLCC). IMAGERY ALSO SHOWS DEEP CONVECTION WEST OF THE LLCC
DEVELOPING IN THE MONSOON TROUGH. THE UW-CIMSS ANALYSIS INDICATES
THAT THE AREA IS UNDER WEAK VERTICAL WIND SHEAR. THE 200 MB ANALYSIS
AND ANIMATED WATER VAPOR IMAGERY INDICATE GOOD OUTFLOW WITH AN
ANTICYCLONE OVER THE AREA. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 997 MB. THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS NOW GOOD.
4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
101600Z8.

REMARKS:
100900Z0 POSITION NEAR 13.1S5 137.5E6.
TC 08P HAS TRACKED SOUTH-SOUTHWEST AT 15 KTS OVER THE
PAST SIX HOURS. WARNING POSITION IS BASED ON 100530Z9 VISIBLE AND
INFRARED ANIMATION. WARNING INTENSITY IS BASED ON INTENSITY
ESTIMATES OF 25 TO 30 KTS. ANIMATED SATELLITE IMAGERY INDICATES A
