SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 95S)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
125 NM EITHER SIDE OF A LINE FROM 14.1S 121.3E TO 16.0S 116.6E
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
IMAGERY AT 190000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 14.3S 121.0E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 09
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED
NEAR 13.7S 121.8E IS NOW LOCATED NEAR 14.3S 121.0E, APPROXIMATELY
231 NM NORTH-NORTHEAST OF BROOME, AUSTRALIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 190105Z MHS 89GHZ MICROWAVE IMAGE DEPICT A
CONSOLIDATING LOW LEVEL CIRCULATION (LLC) WITH CURVED DEEP
CONVECTIVE BANDING WRAPPING INTO THE CENTER. A 181359Z ASCAT PASS
REVEALS A DEFINED CIRCULATION WITH STRONGER WINDS WRAPPING IN FROM
THE SOUTH. UPPER LEVEL ANALYSIS SHOWS AN AREA OF LOW TO MODERATE (10-
20KTS) VERTICAL WIND SHEAR, WITH EQUATORWARD AND POLEWARD OUTFLOW.
WARM SEA SURFACE TEMPERATURES (30-32 CELSIUS) IN THE SURROUNDING
WATERS REMAIN CONDUCIVE FOR FUTURE DEVELOPMENT. DYNAMIC MODELS ARE
IN GOOD AGREEMENT INDICATING A SOUTHWESTWARD TRAJECTORY AND GRADUAL
INTENSIFICATION TO TROPICAL CYCLONE STRENGTH OVER THE NEXT 18-30
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 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
200300Z.
