1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 26JUN25 0000Z, TROPICAL DEPRESSION 02W (SEPAT) WAS 
LOCATED NEAR 35.7N 141.4E, APPROXIMATELY 86 NM EAST-NORTHEAST OF 
YOKOSUKA, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 15 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 260300) FOR FURTHER 
DETAILS.
      (2) AT 26JUN25 0000Z, TROPICAL DEPRESSION 03W (THREE) WAS 
LOCATED NEAR 20.1N 110.7E, APPROXIMATELY 236 NM WEST-SOUTHWEST OF HONG 
KONG, AND HAD TRACKED NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS 
GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 260300) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
14.9N 142.7E IS NOW LOCATED NEAR 15.4N 142.2E, APPROXIMATELY 184 NM 
NORTHWEST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A BROAD LOW LEVEL CIRCULATION (LLC) OBSCURED BY DISORGANIZED 
FLARING CONVECTION. A 252320Z ASCAT PASS REVEALS A BROAD CIRCULATION 
WITH WINDS OF 15-20 KTS IN THE NORTHERN AND EASTERN PERIPHERIES. 
ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES MARGINALLY FAVORABLE 
CONDITIONS FOR DEVELOPMENT WITH MODERATE TO HIGH (20-25 KTS) 
NORTHWESTERLY VERTICAL WIND SHEAR, WARM (29-30C) SEA SURFACE 
TEMPERATURES, AND MODERATE EQUATORWARD OUTFLOW ALOFT. GLOBAL 
DETERMINISTIC MODELS ARE NOT IN AGREEMENT WITH THE DEVELOPMENT OF 97W, 
GFS GRADUALLY INTENSIFIES THE SYSTEM WHILE ECMWF DEPICTS LITTLE TO NO 
DEVELOPMENT OVER THE NEXT 48 HOURS. ENSEMBLE GUIDANCE IS IN FAIR 
AGREEMENT ON A NORTHWEST TRACK WITH GEFS BEING MORE AGGRESSIVE ON 
DEVELOPMENT THAN THAT OF ECENS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (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.//
