RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 15JUL25 1800Z, TROPICAL DEPRESSION 08W (EIGHT) WAS LOCATED
NEAR 39.5N 141.5E, APPROXIMATELY 56 NM SOUTH-SOUTHEAST OF MISAWA, JAPAN,
AND HAD TRACKED NORTHWARD AT 30 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 KNOTS.
SEE REF A (WTPN32 PGTW 152100) FOR THE FINAL WARNING ON THIS SYSTEM.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR 14.1N
131.6E, APPROXIMATELY 572 NM EAST OF CASIGURAN, PHILIPPINES. ANIMATED
MULTISPECTRAL IMAGERY AS WELL AS A 152108Z 91GHZ SSMIS MICROWAVE IMAGE
DEPICT A LARGE CIRCULATION WITH A FAIR AMOUNT OF FLARING CONVECTION
BUILDING OVER THE CENTER ORIGINATING FROM SEVERAL SMALL POCKETS ALONG
THE WESTERN BOUNDARY. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE
CONDITIONS OVERALL FOR DEVELOPMENT WITH LOW (10-15KT) VERTICAL WIND
SHEAR, STRONG DIVERGENT OUTFLOW ALOFT AS WELL AS WARM SEA SURFACE
TEMPERATURES (28-29C). GLOBAL DETERMINISTIC MODELS ARE IN GOOD AGREEMENT
THAT 96W WILL CONTINUE TO CONSOLIDATE STEADILY ALONG A WEST-
NORTHWESTWARD PATH TOWARD LUZON. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS 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.
3. JUSTIFICATION FOR REISSUE: ADDED LOW IN PARA 1.B.(1).//
