REMARKS:
111500Z POSITION NEAR 23.6S 78.0E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 995 NM SOUTH-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWARD AT 11 KNOTS OVER THE
PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
RAPIDLY WEAKENING SYSTEM WITH A PARTIALLY-EXPOSED LOW-LEVEL CIRCUL-
ATION CENTER DISPLACED NORTHWEST OF THE DEEP CONVECTION. AN 110849Z
TRMM IMAGE SHOWED THE BULK OF THE DEEP CONVECTION OVER THE SOUTHERN
SEMI-CIRCLE AND SUPPORTED THE CURRENT POSITION AND MOTION. TC 23S
IS TRACKING SOUTHWARD ALONG THE WESTERN PERIPHERY OF THE LOW- TO
MID-LEVEL SUBTROPICAL RIDGE OVER COOLER SST (25-26C) AND VERY LOW
OCEAN HEAT CONTENT. THE SYSTEM IS FORECAST TO TRACK GENERALLY SOUTH-
WARD INTO A STRONG VERTICAL WIND SHEAR ENVIRONMENT AND WILL INTERACT
WEAKLY WITH A MIDLATITUDE TROUGH THROUGH TAU 36. TC 23S IS EXPECTED
TO CONTINUE TO WEAKEN AND WILL LIKELY DISSIPATE OVER WATER PRIOR
TO COMPLETING EXTRA-TROPICAL TRANSITION AFTER TAU 48. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111200Z IS 28 FEET. NEXT WARNINGS AT
120300Z AND 121500Z. REFER TO TROPICAL CYCLONE 22S (JOKWE) WARN-
INGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
120300Z POSITION NEAR 25.9S 79.4E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 1140 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHEASTWARD AT 10
KNOTS OVER THE PAST 06 HOURS. THE SYSTEM HAS CRESTED THE AXIS OF
THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE AND IS NOW BEGINNING TO
UNDERGO EXTRATROPICAL TRANSITION AS IT MOVES FURTHER INTO COOLER
WATER AND COMES UNDER THE INCREASING INFLUENCE OF THE MIDLATITUDE
TROUGH TO THE WEST. ANIMATED METSAT IMAGERY INDICATES THAT THE
MAJORITY OF THE CONVECTION ASSOCIATED WITH TC 23S IS NOW DETACHED
FROM THE LOW LEVEL CIRCULATION CENTER (LLCC). THE LLCC IS EXPECTED
TO CONTINUE TRACKING SOUTH-SOUTHEASTWARD BEFORE COMPLETING EXTRA-
TROPICAL TRANSITION NEAR TAU 12. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 120000Z IS 18 FEET. REFER TO TROPICAL
CYCLONE 22S (JOKWE) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UP-
DATES.

COOLER (LESS THAN 25 CELSIUS DEGREES FOR THE MOMENT, AND LOWER THAN

THE LLCC IS NOW TOTALLY EXPOSED NORTHWEST OF CONVECTION.
STRONGEST WINDS ARE FORCATED TO EXTEND FAR IN THE SOUTH DUE TO THE
