Cylone "Bandu" .. Final warning ... weakening & marching into Gulf of Aden

JTWC warning:
----------------------------

222100Z POSITION NEAR 12.7N 50.7E.
TROPICAL CYCLONE (TC) 02A (BANDU), LOCATED APPROXIMATELY 60 NM NORTH-
NORTHWEST OF CAPE GUARDAFUI, SOMALIA, HAS TRACKED WEST-NORTHWESTWARD 
AT 02 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE 
IMAGERY AND A 221631Z 91 GHZ SSMIS MICROWAVE IMAGE SHOW THE 
ASSOCIATED DEEP CONVECTION HAS SHEARED AWAY FROM A POORLY ORGANIZED 
LOW LEVEL CIRCULATION CENTER (LLCC). A 221433Z WINDSAT MICROWAVE 
IMAGE ALSO DEPICTS AN UNORGANIZED LLCC. CURRENT INTENSITY IS BASED 
ON PGTW/KNES DVORAK ESTIMATES OF 25 TO 35 KNOTS AND A WINDSAT PASS, 
WHICH SHOWS A MAXIMUM OF 25 KNOTS AROUND THE LLCC. TC 02A IS SLOWLY 
TRACKING ALONG THE SOUTHERN PERIPHERY OF A WEAK LOW-LEVEL 
SUBTROPICAL STEERING RIDGE AND IS FORECAST TO CONTINUE THROUGHOUT 
THE FORECAST PERIOD INTO THE GULF OF ADEN. TC BANDU IS STEADILY 
WEAKENING DUE TO MODERATE NORTHEASTERLY VERTICAL WIND SHEAR, DRY AIR 
IN THE VICINITY, AND LAND INTERACTION. TC 02A IS EXPECTED TO 
CONTINUE TO WEAKEN AND DISSIPATE AS A SIGNIFICANT TROPICAL CYCLONE 
BY TAU 12. AVAILABLE NUMERICAL MODEL GUIDANCE SUPPORTS THIS FORECAST 
TRACK, BUT DOES INDICATE FASTER TRACK SPEEDS, WHICH HAVE VERIFIED 
POORLY. THE REMNANTS SHOULD CONTINUE TRACKING WESTWARD WHILE 
WEAKENING FURTHER. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE 
JOINT TYPHOON WARNING CENTER (NAVMARFCSTCEN).  THE SYSTEM WILL BE 
CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT 
WAVE HEIGHT AT 221800Z IS 15 FEET
