REMARKS:

122100Z POSITION NEAR 15.4N 108.2E.

TROPICAL DEPRESSION 19W (RAI), LOCATED APPROXIMATELY 51 NM

SOUTHEAST OF DA NANG, VIETNAM, HAS TRACKED WEST-NORTHWESTWARD AT

11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)

SATELLITE IMAGERY DEPICTS A BROAD SYSTEM THAT HAS MADE LANDFALL OVER

CENTRAL VIETNAM. THE CURRENT POSITION IS BASED ON THE EIR LOOP AND

SUPPORTED BY A PGTW SATELLITE FIX WITH GOOD CONFIDENCE. THE

INTENSITY IS HELD AT 30 KNOTS BASED ON A 121425Z ASCAT BULLSEYE THAT

SHOWED THE LOW LEVEL CIRCULATION CENTER SITTING JUST OFF THE COAST.

THE CYCLONE WILL CONTINUE TO MOVE WESTWARD UNDER THE INFLUENCE OF A

SUB-TROPICAL RIDGE TO THE NORTH AND FULLY DISSIPATE DUE TO LAND

INTERACTION BY THE END OF THE FORECAST PERIOD. 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.
