1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 01AUG25 1800Z, TROPICAL STORM 12W (KROSA) WAS LOCATED NEAR 
35.2N 141.8E, APPROXIMATELY 75 NM EAST-SOUTHEAST OF NARITA AIRPORT, AND 
HAD TRACKED NORTH-NORTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 
KNOTS. SEE REF A (WTPN31 PGTW 012100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 
25.5N 134.1E IS NOW LOCATED NEAR 26.9N 136.4E, APPROXIMATELY 293 NM 
WEST-NORTHWEST OF IWO TO. ANIMATED MULTISPECTRAL IMAGERY (MSI) DEPICTS A 
CONSOLIDATING, COMPACT LOW LEVEL CIRCULATION CENTER AREA WITH PERSISTENT 
CONVECTION ALONG THE SOUTHEASTERN SEMICIRCLE OF THE CIRCULATION. 
ENVIRONMENTAL ANALYSIS REVEALS MODERATELY FAVORABLE CONDITIONS FOR 
DEVELOPMENT WITH LOW (5-10 KNOTS) VERTICAL WIND SHEAR, A MODERATE 
EQUATORWARD OUTFLOW CHANNEL, AND WARM (28-29C) SEA SURFACE TEMPERATURES. 
CURRENTLY, THE ONLY HINDRANCE AGAINST 93W IS DRY AIR ALONG THE WESTERN 
PERIPHERY OF THE CIRCULATION. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS 
ARE IN GOOD AGREEMENT ON A NORTHEASTWARD TRACK WITH GRADUAL 
INTENSIFICATION OVER THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
HIGH. SEE REF B (WTPN21 PGTW 012300) 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: UPGRADED AREA IN 1.B.(1) TO HIGH.//
