REMARKS:
191500Z POSITION NEAR 17.8N 111.7E.
19NOV24. TROPICAL DEPRESSION 25W (MAN-YI), LOCATED APPROXIMATELY
252 NM EAST-NORTHEAST OF DA NANG, VIETNAM, HAS TRACKED SOUTHWESTWARD
AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY SHOWS THE LOW LEVEL CIRCULATION CENTER (LLCC) HAS
BECOME IRREGULAR AND FULLY EXPOSED AS THE CENTRAL CONVECTION IS
COMPLETELY ERODED AND SHEARED 200+ NM NORTHEASTWARD. THE EIR LOOP ALSO
SHOWS THE LLCC HAS BECOME EMBEDDED IN THE STRATOCUMULUS WIND FIELD
ASSOCIATED WITH THE NORTHEASTERLY SURGE IN THE SOUTH CHINA SEA. THE
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EXPOSED
LLCC. THE INITIAL INTENSITY IS ALSO ASSESSED WITH HIGH CONFIDENCE
BASED ON A CONSENSUS OF AGENCY DVORAK AND AUTOMATED ESTIMATES AND
REFLECTS THE SIGNIFICANT CONVECTIVE DEGRADATION IN THE EIR LOOP.
ANALYSIS INDICATES A HIGHLY UNFAVORABLE ENVIRONMENT WITH STRONG
(25+ KTS) VWS, COOLING SST, AND COLD NORTHEASTERLY WIND SURGE OFFSET
SLIGHTLY BY STRONG POLEWARD OUTFLOW. TD 25W IS EXPECTED TO TRACK
SOUTHWESTWARD AND DISSIPATE BY TAU 12 AS IT HEADS TOWARD DA NANG.
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. MINIMUM CENTRAL PRESSURE AT 191200Z IS 1004 MB. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 191200Z IS 10 FEET.//
