JTWC1330Z再評級Low

(1) AN AREA OF CONVECTION (REMNANTS OF TC 05P) HAS PERSISTED
NEAR 23.9S 178.7E, APPROXIMATELY 382 NM SOUTH-SOUTHEAST OF SUVA,
FIJI. THE SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL STORM,
GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND MID-LATITUDE
CYCLONE FEATURES. ANIMATED ENHANCED INFRARED IMAGERY (EIR) DEPICTS A
FULLY EXPOSED LOW LEVEL CIRCULATION WITH AN AREA OF CONVECTION BEING
SHEARED TO THE SOUTH-SOUTHEAST. A 200704Z SSMIS 91GHZ SATELLITE
IMAGE REVEALS A WELL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC)
WITH AN AREA OF DEEP CONVECTION DISPLACED TO THE SOUTH-SOUTHEAST.
THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT CHARACTERIZED BY HIGH
(20-30 KT) VERTICAL WIND SHEAR (VWS) AND COOL (25C) SEA SURFACE
TEMPERATURES (SST). THE SYSTEM IS ALSO EMBEDDED WITHIN AN UPPER
LEVEL MID-LATITUTE TROUGH. GLOBAL MODELS GENERALLY AGREE THAT THE
SYSTEM WILL SLOWLY TRACK SOUTH-SOUTHWEST AND SLOWLY DISSIPATE.
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 TO 45 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 989 MB. FOR
HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO
HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED
FORECAST AUTHORITY. THE POTENTIAL FOR THE SYSTEM TO TRANSITION INTO
A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

LOCATED NEAR 23.9S 178.7E HAS DISSIPATED AND IS NO LONGER SUSPECT
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24
HOURS.
