(3) THE REMNANTS OF TS 08W (MA-ON) HAS PERSISTED NEAR 31.9N
144.9E, APPROXIMATELY 340 NM SOUTHEAST OF TOKYO, JAPAN. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS THE REMNANTS OF TS 08W
HAS A WELL-DEFINED AND FULLY EXPOSED LLCC WITH DEEP CONVECTION
DISPLACED ALONG THE EASTERN PERIPHERY. THIS SYSTEM IS CURRENTLY
ANALYZED AS SUBTROPICAL. A 230048Z ASCAT PASS DEPICTS WEAK 15 TO 20
KNOT CENTRAL WINDS WITH 35 TO 40 KNOT WINDS ALONG THE OUTER
PERIPHERY. ALSO, A WEAK FRONTAL BOUNDARY IS EVIDENT IN THE ASCAT AND
MSI. SEA SURFACE TEMPERATURES REMAIN HIGH AT APPROXIMATELY 27
DEGREES CELSIUS; HOWEVER, THE RAMMB AMSU CROSS-SECTION DEPICTS A
COLD CORE ANOMALY ALOFT WITH A WARM CORE ANOMALY ONLY IN THE LOWER
LEVELS. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED BENEATH
AN UPPER LEVEL TROUGH IN AN AREA OF HIGH VERTICAL WIND SHEAR (30 TO
35 KNOTS). MAXIMUM SUSTAINED SURFACE WINDS ASSOCIATED WITH THIS
SUBTROPICAL SYSTEM ARE ESTIMATED AT 35 TO 40 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
