REMARKS:
071500Z POSITION NEAR 22.5N 118.4E.
07NOV20. TROPICAL DEPRESSION (TD) 23W (ATSANI), LOCATED
APPROXIMATELY 219 NM SOUTHWEST OF TAIPEI, TAIWAN, HAS TRACKED
WESTWARD AT 06 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY REVEALS RAPIDLY DECAYING,
PARTIALLY-EXPOSED LOW LEVEL CIRCULATION. A 071010Z SSMIS COLOR
COMPOSITE MICROWAVE IMAGE DEPICTS FAINT BANDING WRAPPING INTO A LOW
LEVEL CIRCULATION CENTER (LLCC), WHILE A 071241Z ASCAT-A IMAGE
CAPTURES THE INCREASING WINDS ASSOCIATED WITH THE NORTHEAST SURGE
EVENT IN THE TAIWAN STRAIT WRAPPING AROUND THE NORTHWESTERN QUADRANT
OF A WAVE FEATURE. MULTI-AGENCY DVORAK CURRENT INTENSITY ESTIMATES
OF T1.5-2.0 (25-30 KTS, PGTW/RJTD) AND AN ADVANCED DVORAK CURRENT
INTENSITY ESTIMATE OF T1.5 (25 KTS) SUPPORT THE INITIAL INTENSITY.
THE SYSTEM CONTINUES TO BE IMPACTED BY HIGH (>35 KTS) VERTICAL WIND
SHEAR WHICH, IN CONJUNCTION WITH COOL (25 CELSIUS) SEA SURFACE
TEMPERATURES, WILL CONTINUE TO WEAKEN THE SYSTEM AS IT TRACKS WEST-
SOUTHWESTWARD AND DISSIPATES BY TAU 12. THIS IS THE FINAL WARNING ON
THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071200Z IS 12 FEET.//
