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 
15.2N 115.7E IS NOW LOCATED NEAR 15.2N 114.8E, APPROXIMATELY 349 NM 
EAST OF DA NANG. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS AN EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC), WITH FORMATIVE 
LOW-LEVEL BANDING WRAPPING INTO THE LLCC. A PARTIAL 100223Z ASCAT 
(METOP-C) MICROWAVE IMAGE SHOWS A CLOSED CIRCULATION WITH THE 
STRONGEST WINDS (APPROXIMATELY 20KTS) AROUND THE SOUTHERN PORTION OF 
THE INVEST. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR 
DEVELOPMENT WITH GOOD EQUATORWARD UPPER-LEVEL OUTFLOW, WARM SEA 
SURFACE TEMPERATURES (SST) OF 29-30C, AND LOW TO MODERATE WIND SHEAR 
(15-20 KNOTS). DETERMINISTIC AND ENSEMBLE MODELS ARE IN GOOD AGREEMENT 
THAT 92W WILL DEVELOP WHILE TRACKING TOWARDS THE NORTHWEST OVER THE 
NEXT 24 HOURS. 92W IS GETTING UPGRADED AS A HIGH. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 18 TO 23 . MINIMUM SEA LEVEL PRESSURE 
IS ESTIMATED KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPN21 
PGTW 100930) FOR FURTHER DETAILS.
      (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: JUSTIFICATION FOR REISSUE: UPGRADED AREA 
IN PARA. 1.B.(1) TO HIGH.////
