SUBJ/TROPICAL CYCLONE FORMATION ALERT 282351ZNOV06//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
080 NM EITHER SIDE OF A LINE FROM 9.9S 43.6E TO 11.3S 40.9E WITH-
IN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY IS-
SUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS
IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT
281800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 10.2S
42.9E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 11 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.8S
44.4E, IS NOW LOCATED NEAR 10.2S 42.9E, APPROXIMATELY 580 NM
NORTH-NORTHWEST OF ANTANANARIVO, MADAGASCAR. ANIMATED INFRARED
SATELLITE IMAGERY REVEALS INCREASED CONVECTION OVER THE LOW-LEVEL
CIRCULATION CENTER AND BANDING WRAPPING INTO THE CENTER ON THE
NORTHERN AND SOUTHERN PERIPHERIES OF THE DISTURBANCE. UPPER LEVEL
ANALYSIS INDICATES AN ANTICYCLONE ALOFT OF THE DISTURBANCE
CONTRIBUTING TO GOOD POLEWARD OUTFLOW AND LOW VERTICAL WIND SHEAR.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. DUE
THE DEVELOPMENT OF CONVECTION AROUND THE LOW-LEVEL CIRCULATION
CENTER, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 300000Z.//

REMARKS:
291500Z POSITION NEAR 11.1S 41.7E.
TROPICAL CYCLONE (TC) 03S, LOCATED APPROXIMATELY 570 NM NORTH-
NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHWESTWARD
AT 04 KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED MULTISPEC-
TRAL AND MICROWAVE SATELLITE IMAGERY SHOW DEEP CONVECTIVE
BANDING WRAPPING INTO AN INCREASINGLY WELL-DEFINED CIRCULATION
CENTER. THIS SYSTEM IS EXPECTED TO TRACK GENERALLY SOUTHWARD
OVER THE NEXT 48 ALONG THE WESTERN PERIPHERY OF A STEERING RIDGE
ANCHORED NORTHEAST OF MADAGASCAR. LOW VERTICAL WIND SHEAR AND
GOOD POLEWARD AND EQUATORWARD OUTFLOW ARE EXPECTED TO FACILITATE
INTENSIFICATION AT A CLIMATOLOGICAL RATE THROUGHOUT THE FORECAST
PERIOD. INTENSITY OF THIS SYSTEM WILL DEPEND STRONGLY UPON TRACK.
IF THE STEERING RIDGE BUILDS FURTHER WESTWARD THAN CURRENTLY
FORECAST, THE LOW LEVEL CIRCULATION ASSOCIATED WITH THIS SYSTEM
COULD MOVE ASHORE AND DISSIPATE. THIS POSSIBILITY IS PRESENTED
AS AN ALTERNATE FORECAST SCENARIO. THIS WARNING SUPERSEDES AND

REMARKS:
011500Z POSITION NEAR 15.7S 42.5E.
TROPICAL CYCLONE (TC) 03S (ANITA), LOCATED APPROXIMATELY 345 NM
NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. TC 03S HAS
RECENTLY MAINTAINED INTENSITY DUE TO COMPETING INFLUENCES OF GOOD
UPPER LEVEL OUTFLOW AND MODERATE VERTICAL WIND SHEAR. TC 03S WILL
CONTINUE TRACKING SOUTHWARD ALONG THE WESTERN PERIPHERY OF THE
SUBTROPICAL RIDGE LOCATED EAST OF MADAGASCAR. AS THE SYSTEM MOVES
SOUTH, TC 03S WILL ENCOUNTER INCREASING VERTICAL WIND SHEAR, WHICH
WILL CAUSE WEAKENING FROM TAU 12 AND DISSIPATION BY TAU 36.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011200Z IS 15 FEET.
NEXT WARNINGS AT 020300Z AND 021500Z.//

REMARKS:
020300Z POSITION NEAR 16.9S 42.9E.
TROPICAL CYCLONE (TC) 03S (ANITA), LOCATED APPROXIMATELY 275 NM
WEST-NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. ALTHOUGH THE
LOW-LEVEL CIRCULATION ASSOCIATED WITH TC 03S REMAINS WELL-DEFINED,
THE DEEP CONVECTION ASSOCIATED WITH TC 03S HAS DISSIPATED DUE TO
MODERATE TO HIGH VERTICAL WIND SHEAR. THE LOW-LEVEL CIRCULATION
WILL CONTINUE TO TRACK TO THE SOUTH-SOUTHEAST, BUT DUE TO CONTINUED
UNFAVORABLE CONDITIONS REGENERATION OF TC 03S IS UNLIKELY. 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 020000Z
IS 12 FEET.//
