1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03AUG26 0000Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 24.4N 
148.4E, APPROXIMATELY 388 NM EAST OF IWO TO, AND HAD TRACKED WEST-
NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 100 KNOTS GUSTING TO 125 KNOTS. SEE REF 
A (WTPN31 PGTW 030300) 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 17.4N 122.8E, APPROXIMATELY 80 NM 
SOUTHEAST OF APARRI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
REVEALS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) THAT IS 
COMPLETELY VOID OF CONVECTION AND TRANSITING NORTH-NORTHWESTWARD. 
ENVIRONMENTAL ANALYSIS REVEALS MARGINAL CONDITIONS FOR TROPICAL CYCLONE 
DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (15 KNOTS OR LESS), GOOD 
EQUATORWARD OUTFLOW ALOFT, AND VERY WARM (30-31 C) SEA SURFACE 
TEMPERATURES, OFFSET BY SIGNIFICANT DRY AIR ALONG THE EASTERN PERIPHERY 
AND ELEVATED GRADIENT FLOW TO THE SOUTH CAUSED BY INFLOW INTO TYPHOON 
12W (DOLPHIN). GLOBAL DETERMINISTIC MODELS AGREE THAT 94W IS PAST ITS 
PEAK AND WILL WEAKEN UNTIL BEING FULLY ABSORBED BY TYPHOON 12W WITHIN 
24-36 HOURS. THERE REMAINS A BRIEF PERIOD OF TIME WHERE THE SYSTEM MAY 
MOMENTARILY REACH TROPICAL CYCLONE CRITERIA, THEREFORE, THE POTENTIAL 
FOR TROPICAL CYCLONE DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 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 REMAINS HIGH.
      (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.//
