1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04AUG26 0000Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
25.1N 143.2E, APPROXIMATELY 836 NM EAST OF KADENA AB, AND HAD TRACKED 
WESTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS WERE ESTIMATED AT 100 KNOTS GUSTING TO 125 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 
17.7N 121.8E IS NOW LOCATED NEAR 17.7N 120.2E, APPROXIMATELY 15 NM 
NORTHWEST OF VIGAN, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) REVEALS AN OBSCURED LOW LEVEL CIRCULATION CENTER (LLCC) 
THAT TRACKED UNDER DEEP CONVECTION AFTER IT MADE LANDFALL IN LUZON. 
ENVIRONMENTAL ANALYSIS REVEALS HIGHLY UNFAVORABLE CONDITIONS FOR 
TROPICAL CYCLONE DEVELOPMENT CHARACTERIZED BY LAND INTERACTION, HIGH 
VERTICAL WIND SHEAR (GREATER THAN 30 KNOTS) AND SIGNIFICANT DRY AIR 
ALONG THE EASTERN PERIPHERY, AS WELL AS ELEVATED GRADIENT FLOW TO THE 
SOUTH CAUSED BY INFLOW INTO TYPHOON 12W (DOLPHIN) AND ELEVEATED 
GRADIENT FLOW TO THE WEST FROM FUNNELING EFFECTS IN THE LUZON STRAIT. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12 TO 18 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 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.//
