1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 07OCT25 0000Z, TYPHOON 28W (HALONG) WAS LOCATED NEAR 26.9N 
138.6E, APPROXIMATELY 193 NM NORTHWEST OF IWO TO, AND HAD TRACKED WEST-
NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 80 KNOTS GUSTING TO 100 KNOTS. SEE REF A 
(WTPN32 PGTW 070300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 
12.7N 146.3E IS NOW LOCATED NEAR 14.7N 144.5E, APPROXIMATELY 76 NM NORTH 
OF GUAM. ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS 
A CONSOLIDATING LOW LEVEL CIRCULATION CENTER WITH BUILDING DEEP 
CONVECTION. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES FAVORABLE 
CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR, WARM SEA 
SURFACE TEMPERATURES, AND GOOD EQUATORWARD OUTFLOW ALOFT. GLOBAL 
DETERMINISTIC MODELS ARE IN GOOD AGREEMENT THAT 95W WILL DEVELOP TO THE 
NORTH, AND GFS INDICATES THE MOST INTENSE DEVELOPMENT OVER THE NEXT 48 
HOURS. GLOBAL ENSEMBLE GUIDANCE HAS SHOWN 95W MOVING NORTH-NORTHWESTWARD 
WITH BOTH GEFS AND ECENS IN FAIR AGREEMENT ON THE DEVELOPMENT TIMELINE 
OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
18 TO 23 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 HIGH.SEE REF B (WTPN21 PGTW 
070300) 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.//
