REMARKS:
140900Z POSITION NEAR 19.5N 106.4E.
14OCT21. TROPICAL DEPRESSION 24W (KOMPASU), LOCATED APPROXIMATELY
101 NM SOUTH-SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED WEST-
NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY SHOWS THE SYSTEM IS COMPLETELY
STRIPPED OF ANY DEEP CONVECTION, FULLY EXPOSING A RAGGED AND WEAK
LOW LEVEL CIRCULATION WHERE THE INITIAL POSITION IS PLACED WITH HIGH
CONFIDENCE. THE INITIAL INTENSITY IS BASED ON OVERALL ASSESSMENT OF
AGENCY DVORAK ESTIMATES AND EXTRAPOLATED FROM NEARBY SURFACE
OBSERVATIONS. ENVIRONMENTAL ANALYSIS INDICATES MEDIUM (15-20KT)
VERTICAL WIND SHEAR, GREATLY DIMINISHED OUTFLOW, AND DRY AIR
ENTRAINMENT FROM THE NORTHWEST HAVE DRASTICALLY ERODED THE
ASSOCIATED CONVECTION. 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 140600Z
IS 10 FEET. REFER TO TROPICAL DEPRESSION 23W (NAMTHEUN) WARNINGS
(WTPN32 PGTW) FOR SIX-HOURLY UPDATES.//
