211500Z POSITION NEAR 24.3N 139.2E.
21OCT20. TROPICAL DEPRESSION 20W (TWENTY), LOCATED APPROXIMATELY 112
NM WEST-SOUTHWEST OF IWO TO, JAPAN, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY AND A 210854Z SSMIS 91 GHZ MICROWAVE IMAGE
DEPICT A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH SOME
WEAK BANDING WRAPPING IN FROM THE WEST. A BULLSEYE 211127Z ASCAT-A
IMAGE REVEALING A SWATH OF 20-25KT WINDS TO THE NORTH AND NORTHWEST
WITH WEAKER WINDS ELSEWHERE. BASED ON THE AFOREMENTIONED ASCAT
IMAGE, THERE IS GOOD CONFIDENCE IN THE INITIAL POSITION AND INITIAL
INTENSITY OF 25 KTS. ENVIRONMENTAL ANALYSIS INDICATES AN UNFAVORABLE
ENVIRONMENT WITH STRONG (40-45 KTS) VERTICAL WIND SHEAR (VWS) BEING
SLIGHTLY OFFSET BY WARM (28-29 CELSIUS) SEA SURFACE TEMPERATURES AND
EQUATORWARD OUTFLOW. TD 20W IS CURRENTLY TRACKING WITHIN A WEAK
STEERING ENVIRONMENT AS A SHORTWAVE TROUGH POSITIONED TO THE
NORTHEAST WEAKENED THE STEERING SUBTROPICAL RIDGE (STR). AS THE
SHORTWAVE TROUGH PROPAGATES EASTWARD, THE STR WILL BEGIN TO REBUILD
AND REORIENT POLEWARD ALLOWING TD 20W TO TURN NORTHWESTWARD THEN
NORTHWARD, TRACKING ALONG THE PERIPHERY OF THE STR. PERSISTENT
STRONG (40-45 KTS) VWS WILL CAUSE TD 20W TO QUICKLY WEAKEN,
DISSIPATING BY TAU 12. THE REMNANTS OF THE SYSTEM WILL BE ABSORBED
BY A DEVELOPING FRONT SOUTHEAST OF THE KANTO PLAIN. NUMERICAL MODEL
GUIDANCE IS IN GOOD AGREEMENT. HOWEVER, DUE TO THE CURRENT WEAK
STEERING ENVIRONMENT, THERE IS OVERALL FAIR CONFIDENCE IN THE JTWC
FORECAST TRACK WHICH IS PLACED NEAR THE MULTI-MODEL CONSENSUS. 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 211200Z IS 9 FEET.
REFER TO TROPICAL STORM 19W (SAUDEL) WARNINGS (WTPN31 PGTW) FOR SIX-
