27NOV25. TROPICAL CYCLONE 04B (SENYAR), LOCATED APPROXIMATELY
572 NM SOUTHWEST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED EASTWARD
AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL
IMAGERY DEPICTS TROPICAL CYCLONE (TC) 04B WITH A PARTIALLY OBSCURED
LOW-LEVEL CIRCULATION CENTER WITH ASSOCIATED SPORATIC AND
SHORT-LIVED FLARING CONVECTION THROUGHOUT THE BAY OF MALACCA.
ENVIRONMENTAL ANALYSIS INDICATES THAT TROPICAL CYCLONE 04B IS IN AN
UNFAVORABLE ENVIRONMENT, CHARACTERIZED BY HIGH VERTICAL WIND SHEAR
(20-25 KTS) AND INCREASED FRICTIONAL IMPACTS DUE TO LAND INTERACTION
AS THE SYSTEM APPROACHES THE WEST COAST OF  MALAYSIA. OVER THE NEXT
12 HOURS, TC 04B IS FORECASTED TO CONTINUE EASTWARD AND MAKE LANDFALL
JUST PRIOR TO TAU 12. REGARDING INTENSITY, THE JTWC INTENSITY FORECAST
IS ALIGED CLOSELY TO THE JTWC CONSENSUS, MAINTAINING 25 KTS UNTIL 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. MINIMUM CENTRAL PRESSURE 
AT 270000Z IS 1005 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270000Z IS 8
FEET. REFER TO TROPICAL CYCLONE 05B WARNINGS (WTIO32 PGTW) FOR SIX-
HOURLY UPDATES.//
