1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04OCT25 0000Z, TROPICAL STORM 27W (MATMO) WAS LOCATED NEAR 
18.2N 116.7E, APPROXIMATELY 283 NM SOUTH-SOUTHEAST OF HONG KONG, AND 
HAD TRACKED WEST-NORTHWESTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 60 KNOTS GUSTING TO 
75 KNOTS. SEE REF A (WTPN31 PGTW 040300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
21.6N 144.7E IS NOW LOCATED NEAR 23.4N 143.1E, APPROXIMATELY 129 NM 
SOUTHEAST OF IWO TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
AN OBSCURED, LOW LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT 
CONVECTION OVER THE CENTER. A RECENT 040040Z ASCAT-C 25 KM PASS REVEALS 
A CIRCULATION WITH 20-25 KNOTS ALONG THE EASTERN QUADRANT AND 5-15 KNOTS 
ELSEWHERE. ENVIRONMENTAL ANALYSIS REVEALS A MARGINALLY FAVORABLE 
ENVIRONMENT WITH LOW TO MODERATE LEVEL VERTICAL WIND SHEAR OF 15-20 
KNOTS, GOOD DUAL CHANNEL UPPER-LEVEL OUTFLOW, AND WARM SEA SURFACE 
TEMPERATURES (SST) OF 29-30 C. GLOBAL MODELS ARE NOT IN AGREEMENT UPON 
INTENSITY BUT DO CONCUR WITH A WESTWARD TRACK TOWARD TAIWAN. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 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.//
