1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 25JUL23 1200Z, TYPHOON 05W (DOKSURI) WAS LOCATED NEAR 18.9N 
122.7E, APPROXIMATELY 276 NM NORTH-NORTHEAST OF MANILA, PHILIPPINES, AND 
HAD TRACKED WEST-NORTHWESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 120 KNOTS GUSTING TO 
145 KNOTS. SEE REF A (WTPN31 PGTW 251500) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
8.0N 141.4E IS NOW LOCATED NEAR 8.7N 141.6E, APPROXIMATELY 207 NM EAST-
SOUTHEAST OF YAP. ENHANCED INFRARED SATELLITE IMAGERY AND A 250846Z 
SSMIS 91GHZ MICROWAVE IMAGE DEPICT AN ELONGATED LOW-LEVEL CIRCULATION 
(LLC) WITH FRAGMENTED BANDING BEGINNING TO WRAP INTO THE LLC FROM THE 
NORTHERN AND SOUTHERN PERIPHERIES. A 251226Z ASCAT-B BULLSEYE PASS 
REVEALS A MORE DEFINED BUT ELONGATED CIRCULATION WITH 15-20 KNOT WINDS 
ALONG THE WESTERN AND SOUTHERN PERIPHERIES AND FEW 25-30 KNOT WINDS OFF 
SET TO THE SOUTHERN SEMICIRCLE. INVEST 91W REMAINS IN A MARGINAL 
ENVIRONMENT FOR DEVELOPMENT DUE TO THE NORTHERLY OUTFLOW FROM TY 05W 
PLACING THE SYSTEM UNDER MODERATE (20KT) VERTICAL WIND SHEAR. SEA 
SURFACE TEMPERATURES ARE CONDUCIVE AT A WARM 29-30C. GLOBAL MODELS ARE 
IN GOOD AGREEMENT THAT INVEST 91W WILL CONTINUE TO CONSOLIDATE AS IT 
TRACKS NORTH-NORTHWESTWARD OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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.//
