1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR
13.1N 136.0E IS NOW LOCATED NEAR 13.9N 137.0E, APPROXIMATELY 272 NM
NORTH-NORTHWEST OF YAP. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
(EIR) DEPICTS AN AREA OF BROAD CYCLONIC TURNING OBSCURED BY DEEP,
FLARING CONVECTION. FURTHERMORE, A 211321Z ASCAT METOP-C IMAGE DEPICTS
AN AREA OF POORLY-DEFINED CYCLONIC CIRCULATION, WITH WIND SPEEDS
RANGING FROM 15-20KTS. UPPER-LEVEL ANALYSIS INDICATES THAT 92W IS IN A
FAVORABLE ENVIRONMENT FOR DEVELOPMENT, WITH LOW (5-10KT) VWS, GOOD
DIVERGENCE ALOFT, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL
MODELS ARE IN GENERAL AGREEMENT THAT 92W WILL CONTINUE TO MOVE WEST-
NORTHWESTWARD AS IT INTENSIFIES. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 18 TO 23 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.
(2) NO OTHER SUSPECT AREAS.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO
MEDIUM.//
