1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):

   A. TROPICAL CYCLONE SUMMARY:

      (1) AT 05OCT25 1800Z, TYPHOON 27W (MATMO) WAS LOCATED NEAR 21.9N

108.5E, APPROXIMATELY 155 NM EAST- NORTHEAST OF HANOI, VIETNAM, AND

HAD TRACKED WEST-NORTHWESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS.

MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS GUSTING TO

80 KNOTS. SEE REF A (WTPN31 PGTW 052100) FOR THE FINAL WARNING ON THIS

SYSTEM.

      (2) AT 06OCT25 1200Z, TYPHOON 28W (HALONG) WAS LOCATED NEAR

26.2N 140.0E, APPROXIMATELY 546 NM SOUTH OF YOKOSUKA, JAPAN, AND HAD

TRACKED WEST-NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS.

MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 70 KNOTS GUSTING TO

85 KNOTS. SEE REF A (WTPN32 PGTW 061500) FOR FURTHER DETAILS.

      (3) NO OTHER TROPICAL CYCLONES.

   B. TROPICAL DISTURBANCE SUMMARY:

      (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR

12.0N 147.9E IS NOW LOCATED NEAR 12.7N 146.3E, APPROXIMATELY 103 NM

EAST-SOUTHEAST OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY

(EIR) DEPICTS A DISORGANIZED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH

FRAGMENTED FORMATIVE BANDING. A 061108Z ASCAT REVEALS A BROAD

CIRCULATION WITH 20 KNOT WINDS OVER 90 NAUTICAL MILES ALONG THE

EASTERN PERIPHERY. ENVIRONMENTAL ANALYSIS 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

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 1007 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.//
