1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 02AUG26 1200Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
23.6N 150.9E, APPROXIMATELY 530 NM EAST OF IWO TO, AND HAD TRACKED 
WEST-NORTHWESTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 110 KNOTS GUSTING TO 135 
KNOTS. SEE REF A (WTPN31 PGTW 021500) 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 15.9N 123.1E, APPROXIMATELY 62 NM 
EAST-SOUTHEAST OF CASIGURAN. ANIMATED ENHANCED INFRARED IMAGERY (EIR) 
DEPICTS CONVECTION ASSOCIATED WITH A MID-LEVEL CIRCULATION DISPLACED 
SOUTHWEST OF A FULLY EXPOSED, DISORGANIZED LOW-LEVEL CIRCULATION 
CENTER. A 021240Z METOP-C ASCAT IMAGE REVEALS AN ELONGATED CIRCULATION 
WITH ENHANCED 20-25 KNOT WINDS IN THE SOUTHERN PERIPHERY. 
ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES UNFAVORABLE CONDITIONS 
FOR DEVELOPMENT WITH MODERATE VERTICAL WIND SHEAR (15-20 KNOTS) AND 
DRY AIR, OFFSET BY VERY WARM SEA SURFACE TEMPERATURES (30-31 C) AND 
GOOD EQUATORWARD OUTFLOW ALOFT. A MARGINAL IMPROVEMENT IN STRUCTURE 
WOULD NECESSITATE INITIATION OF TROPICAL CYCLONE WARNINGS. GLOBAL 
DETERMINISTIC DATA AGREES THAT THE BEST CHANCE OF DEVELOPMENT INTO A 
TROPICAL DEPRESSION OR TROPICAL STORM IS IN THE NEXT 6 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 20 TO 
25 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 UPGRADED TO HIGH. 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: UPGRADED AREA IN PARA. 1.B.(1) TO 
HIGH.//
