1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 13AUG25 1800Z, TROPICAL STORM 16W (PODUL) WAS LOCATED 
NEAR 24.3N 116.9E, APPROXIMATELY 191 NM NORTHEAST OF HONG KONG, AND 
HAD TRACKED WEST-NORTHWESTWARD AT 20 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 
55 KNOTS. SEE REF A (WTPN32 PGTW 132100) FOR THE FINAL WARNING ON 
THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 99W) HAS PERSISTED NEAR 25.6N 
178.2E, APPROXIMATELY 285 NM WEST-SOUTHWEST OF MIDWAY. THE SYSTEM IS 
CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY 
CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE 
FEATURES. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS AN 
EXTREMELY ELONGATED CIRCULATION LOCATED ALONG THE SOUTHWESTERN END OF 
A WEAK FRONTAL BAND AND A PARTIALLY EXPOSED LLCC TYPICAL OF A 
SUBTROPICAL SYSTEM. A 130946Z ASCAT-C PASS REVEALS WINDS OF UP TO 25 
KNOTS OVER THE SOUTHERN PERIPHERY OF THE LLCC, WITH WINDS ON THE 
EASTERN SIDE NOW WRAPPING INTO THE LLCC, SEPARATING IT FROM THE 
FRONTAL BAND. ENVIRONMENTAL ANALYSIS REVEALS UNFAVORABLE CONDITIONS 
FOR TROPICAL TRANSITION DEFINED BY A DEEP LAYER OF DRY AIR BEING 
ADVECTED OVER THE CIRCULATION, COOL (26-27C) SEA SURFACE TEMPERATURES 
AND LIGHT TO MODERATE NORTHERLY SHEAR IMPARTED BY A VERY LARGE UPPER-
LEVEL LOW POSITIONED TO THE NORTH. GLOBAL MODELS ARE IN AGREEMENT 
THAT 99W WILL CONTINUE TO TRACK NORTHEAST AND THEN NORTHWARD OVER THE 
NEXT 24-48 HOURS, WITH A BROAD AND ASYMMETRIC WIND FIELD POSITIONED 
WELL AWAY FROM THE CENTER. 99W WILL MOVE UNDER THE UPPER-LEVEL LOW 
WITHIN THE NEXT 36 HOURS AND TRANSITION TO A COLD-CORE LOW. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. FOR HAZARDS AND 
WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND 
SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
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: UPDATED PARA. 1.A.(1) WITH 16W FINAL 
WARNING INFORMATION.//
