1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03AUG26 1200Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
25.0N 145.7E, APPROXIMATELY 240 NM EAST OF IWO TO, AND HAD TRACKED 
WESTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 90 KNOTS GUSTING TO 110 KNOTS. SEE REF 
A (WTPN31 PGTW 031500) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
15.9N 124.4E IS NOW LOCATED NEAR 17.7N 121.8E, APPROXIMATELY 40 NM 
SOUTH-SOUTHEAST OF APARRI. 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 (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 1003 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
IS DOWNGRADED TO LOW. SEE REF B (WTPN21 PGTW 021930) 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: DOWNGRADED AREA IN PARA. 2.B.(1) TO 
LOW.//
