1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 01AUG26 1200Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 21.6N 
156.2E, APPROXIMATELY 843 NM EAST OF IWO TO, AND HAD TRACKED 
NORTHWESTWARD AT 15 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 120 KNOTS GUSTING TO 145 KNOTS. SEE REF 
A (WTPN31 PGTW 011500) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 14.3N 
126.1E, APPROXIMATELY 152 NM EAST-NORTHEAST OF LEGAZPI. ANIMATED 
ENHANCED INFRARED IMAGERY (EIR) DEPICTS DEEP CONVECTION ASSOCIATED WITH 
A MID-LEVEL CIRCULATION DISPLACED SOUTHWEST OF THE SLOWLY CONSOLIDATING 
LOW-LEVEL CIRCULATION CENTER. ENVIRONMENTAL ANALYSIS FOR THE AREA 
INDICATES FAVORABLE CONDITIONS FOR DEVELOPMENT WITH WARM SEA SURFACE 
TEMPERATURES (29-30 C), LOW VERTICAL WIND SHEAR (10-15 KTS), AND GOOD 
EQUATORWARD OUTFLOW ALOFT. THE ECMWF DETERMINISTIC MODEL DEPICTS GRADUAL 
DEVELOPMENT OF 94W INTO A TROPICAL DEPRESSION OR WEAK TROPICAL STORM 
OVER THE NEXT 36 HOURS. THE ECENS AND DEEPMIND ENSEMBLES CONCUR ON A 
SLOW TO QUASI-STATIONARY MOTION NEAR SOUTHERN LUZON AND POSSIBLE 
INTERACTION WITH TY 12W IN A COUPLE OF DAYS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1005 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.//
