REMARKS:
301500Z POSITION NEAR 18.0N 103.6E.
30AUG25. TROPICAL DEPRESSION 20W (NONGFA), LOCATED APPROXIMATELY
199 NM SOUTH-SOUTHWEST OF HANOI, VIETNAM, HAS TRACKED WESTWARD AT
21 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY REVEALS THE LOW-LEVEL CIRCULATION CENTER IS
OBSCURED BY UPPER-LEVEL CLOUD COVER AND FLARING CONVECTION. A
301143Z 91GHZ SSMIS IMAGE SHOWS THAT THE CONVECTION IS CONFINED TO
THE WESTERN PERIPHERY OF THE SYSTEM. NONGFA MADE LANDFALL SHORTLY
AFTER 0600Z AND HAS RAPIDLY DETERIORATED OVER THE MOUNTAINOUS
TERRAIN IN VIETNAM AND LAOS. 20W IS FORECAST TO CONTINUE TO WEAKEN,
WITH DISSIPATION FORECAST TO OCCUR PRIOR TO TAU 12. SOME MODELS DO
TRACK THE REMNANT VORTICITY OF 20W INTO THE BAY OF BENGAL, BUT A
VERY LOW CHANCE OF ANY SIGNIFICANT DEVELOPMENT IS EXPECTED DUE TO
THE AMOUNT OF TIME OVER LAND. 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 301200Z IS 1000 MB.//
