WPAC: YAGI - Tropical Storm

[euro6208]

stubborn yagi still lingering south of japan...


THE AREA OF CONVECTION (REMNANTS OF TD 03W) PREVIOUSLY
LOCATED NEAR 32.2N 138.6E, IS NOW LOCATED NEAR 31.2N 139.1E,
APPROXIMATELY 270 NM SOUTH OF TOKYO, JAPAN. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS THE REMNANTS OF TD 03W HAVE MAINTAINED A
BROAD LOW LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT SHALLOW
CONVECTION. ALTHOUGH THIS SYSTEM HAS DISSIPATED AS A SIGNIFICANT
TROPICAL CYCLONE, IT CONTINUES TO EXHIBIT SUBTROPICAL
CHARACTERISTICS WHILE PERSISTING OVER COOLER SEA SURFACE
TEMPERATURES (<24 DEGREES CELSIUS) IN CLOSE PROXIMITY TO THE
BAROCLINIC ZONE. A 140030Z AMSU-B MICROWAVE IMAGE DEPICTS SHALLOW
CONVECTION, ALONG WITH DRY CONTINENTAL AIR, IS WRAPPING INTO THE
ELONGATED LLCC. SCATTEROMETER DATA CONTINUES TO INDICATE 20 KNOT
WINDS SURROUNDING THE LLCC WITH STRONGER GRADIENT FLOW TO THE
NORTHWEST. UPPER LEVEL ANALYSIS INDICATES AN UNFAVORABLE ENVIRONMENT
AS AN UPPER-LEVEL LOW HAS PERSISTED OVER THE SYSTEM WHICH IS AN AREA
OF LOW VERTICAL WIND SHEAR (5 TO 10 KNOTS). MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. DUE TO THE ENVIRONMENTAL
CONDITIONS, THE POTENTIAL FOR THIS SUBTROPICAL SYSTEM TO REDEVELOP
INTO A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS
LOW.
