1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 12OCT26 0000Z, TROPICAL DEPRESSION 28W (TWENTYEIGHT) WAS 
LOCATED NEAR 16.4N 150.8E, APPROXIMATELY 378 NM EAST-NORTHEAST OF 
ANDERSEN AFB, AND HAD TRACKED NORTH-NORTHWESTWARD AT 04 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
25 KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 120300) FOR 
FURTHER DETAILS.
      (2) AT 12OCT26 0000Z, TYPHOON 27W (KOGUMA) WAS LOCATED NEAR 
28.3N 147.3E, APPROXIMATELY 571 NM SOUTHEAST OF YOKOSUKA, JAPAN, AND 
HAD TRACKED NORTHWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 100 KNOTS GUSTING TO 125 
KNOTS. SEE REF B (WTPN33 PGTW 120300) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 
16.4N 150.7E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 1.A.(1) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 
9.5N 163.5E IS NOW LOCATED NEAR 9.0N 163.0E, APPROXIMATELY 150 NM 
EAST-SOUTHEAST OF UJELANG. MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A DISORGANIZED LOW LEVEL CIRCULATION, WITH FLARING CONVECTION 
TO THE SOUTHWEST SATELLITE DATA INDICATES THAT 96W DOES NOT HAVE A 
CLOSED LOW-LEVEL CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS A 
FAVORABLE AREA FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-15 
KTS), MODERATE RADIAL OUTFLOW, AND WARM SEA SURFACE TEMPERATURES (29-
30C). GLOBAL DETERMINISTIC AND ENSEMBLE MODELS DEPICT STEADY 
DEVELOPMENT OVER THE NEXT 48 HOURS WHILE THE SYSTEM TRACKS WEST-
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 
18 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.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 15E) PREVIOUSLY LOCATED NEAR 
32.4N 144.9E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
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 
WARNING STATUS.//
