1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR
14.3N 130.6E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
(2) NO OTHER SUSPECT AREAS.
C. SUBTROPICAL SYSTEM SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 28.3N
152.9E, APPROXIMATELY 68 NM EAST-NORTHEAST OF IWO TO. THIS SYSTEM IS
CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS
HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS A CONSOLIDATING, EXPOSED LOW-LEVEL
CIRCULATION CENTER (LLCC) THAT IS SUBTROPICAL IN NATURE WITH CONVECTION
DISPLACED POLEWARD AND EASTWARD OF THE LLCC. A 130003Z ASCAT METOP-C
IMAGE REVEALS 25 KNOT WINDS ISOLATED TO THE EASTERN SEMICIRCLE OF THE
CIRCULATION. ENVIRONMENTAL ANALYSIS INDICATES MARGINALLY FAVORABLE
CONDITIONS WITH MODERATE TO HIGH (20-25 KTS) VERTICAL WIND SHEAR, GOOD
POLEWARD OUTFLOW ALOFT, DRY AIR ENTRAINMENT, AND WARM (27-28 C) SEA
SURFACE TEMPERATURES. THE PROBABILITY OF TROPICAL TRANSITION IS ASSESSED
AS LOW AS THE SYSTEM IS EXPECTED TO TRACK NORTHEASTWARD AND QUICKLY
BECOME EMBEDDED IN THE UPPER-LEVEL JET. FOR HAZARDS AND WARNINGS,
REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT
OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 22 TO 27 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
(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.//
