1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 25SEP23 0600Z, TROPICAL DEPRESSION 13W (THIRTEEN) WAS 
LOCATED NEAR 15.9N 109.5E, APPROXIMATELY 69 NM EAST OF DA NANG, VIETNAM, 
AND HAD TRACKED NORTHWESTWARD AT 15 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 
KNOTS. SEE REF A (WTPN31 PGTW 250900) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
14.8N 110.5E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE PARA. 
1.A.(1) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
17.1N 147.3E IS NOW LOCATED NEAR 21.6N 143.3E, APPROXIMATELY 215 NM 
SOUTH-SOUTHEAST OF IWO TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
AND A 250328Z 88.2 GHZ ATMS MICROWAVE IMAGE DEPICT AN EXPOSED LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH CONVECTION DISPLACED TO THE EAST 
OF THE CIRCULATION CENTER. ENVIRONMENTAL ANALYSIS INDICATES THAT 92W 
IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD POLEWARD 
OUTFLOW ALOFT, LOW (10-15 KTS) VERTICAL WIND SHEAR, AND WARM (30 C) 
SST. GLOBAL NUMERICAL DETERMINISTIC AND ENSEMBLE MODELS AGREE THAT 92W 
WILL TRACK NORTHWESTWARD AND CONTINUE TO DEVELOP OVER THE NEXT 48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM 
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS REMAINS LOW.
      (3) 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 WARNING 
STATUS.//
