1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 01AUG25 0600Z, TROPICAL STORM 12W (KROSA) WAS LOCATED NEAR 
33.7N 141.3E, APPROXIMATELY 124 NM SOUTHEAST OF YOKOSUKA, JAPAN, AND HAD 
TRACKED NORTHWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 KNOTS. SEE REF A 
(WTPN31 PGTW 010900) 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 26.3N 135.1E, APPROXIMATELY 395 NM EAST 
OF KADENA. ANIMATED MULTISPECTRAL IMAGERY (MSI) DEPICTS AN ELONGATED 
AREA OF FLARING CONVECTION. A PARTIAL 010502Z ASCAT-B PASS REVEALS AN 
ASYMMETRIC WEAK WIND FIELD OF 15-20 KNOT WINDS ALONG THE SOUTHERN 
PERIPHERY DUE TO THE ENHANCED MONSOONAL FLOW. ENVIRONMENTAL ANALYSIS 
REVEALS A MARGINAL CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE 
VERTICAL WIND SHEAR, MODERATE UPPER-LEVEL DIVERGENCE AND POLEWARD 
OUTFLOW, AND WARM (28-29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE 
IN MODERATE AGREEMENT THAT INVEST 93W WILL DEVELOP WHILE TRACKING 
NORTHEASTWARD IN 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 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.//
