REMARKS:
230900Z POSITION NEAR 20.2N 106.6E.
TROPICAL DEPRESSION 05W (BEBINCA), LOCATED APPROXIMATELY 75 NM
SOUTHEASTWARD OF HANOI, VIETNAM, HAS TRACKED NORTHWESTWARD AT 10
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE (MSI)
IMAGERY SHOWS THE FULLY EXPOSED LOW LEVEL CIRCULATION CENTER HAS
VEERED NORTHWESTWARD WITH THE LOW LEVEL FLOW AS MOST OF THE
CONVECTION CONTINUED TO BE SEVERELY SHEARED TO THE SOUTHWEST, NOW
INTO CENTRAL VIETNAM. THE INITIAL POSITION IS BASED ON THE MSI LOOP
WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS BASED ON DVORAK
ESTIMATES FROM PGTW AND RJTD. UPPER LEVEL ANALYSIS INDICATES THE
SYSTEM REMAINS WELL SOUTH OF THE RIDGE AXIS IN AN AREA OF STRONG
(25-30 KNOT) NORTHEASTERLY VERTICAL WIND SHEAR. THE EQUATORWARD
OUTFLOW REMAINS SOLID; HOWEVER, THE REMNANT CONVECTION IS BEING
ERODED RAPIDLY BY LAND INTERACTION. THE CYCLONE IS NOW TRACKING WITH
THE GRADIENT FLOW AND IS EXPECTED TO MAKE LANDFALL OVER THE NEXT FEW
HOURS JUST SOUTHEAST OF HANOI THEN DISSIPATE INLAND BY TAU 12. 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 230600Z IS 10 FEET.
