SUBJ/TROPICAL CYCLONE FORMATION ALERT 231351Z JAN 02//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
125 NM EITHER SIDE OF A LINE FROM 11.5S7 89.8E5 TO 14.8S3 86.6E0
WITHIN THE NEXT 06 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 30 KNOTS. METSAT
IMAGERY AT 231330Z2 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 11.9S1 89.2E9. THE SYSTEM IS MOVING SOUTHWESTWARD
AT 04 KNOTS.
2. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.2S4 90.4E3 IS NOW
LOCATED NEAR 11.9S1 89.2E9, ABOUT 450 NM WEST OF COCOS ISLAND, IN
THE SOUTHERN INDIAN OCEAN. ANIMATED VISIBLE SATELLITE IMAGERY
INDICATES INCREASING ORGANIZATION OF A FAIRLY WELL DEFINED LOW-LEVEL
CIRCULATION CENTER (LLCC). 200 MB ANALYSIS INDICATES CONVECTION IS
CURRENTLY IN A REGION OF WEAK TO MODERATE VERTICAL WIND SHEAR AND
MOVING INTO AN AREA FAVORABLE FOR FURTHER DEVELOPMENT. THE
POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS NOW GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
241400Z1.//

REMARKS:
240900Z5 POSITION NEAR 12.3S6 88.4E0.
TROPICAL CYCLONE 11S HAS DEVELOPED OVER THE NEAR EQUATORIAL TROUGH
APPROXIMATELY 5 NM WEST OF COCOS ISLAND. TROPICAL CYCLONE 11S HAS
TRACKED SOUTHWESTWARD AT 05 KNOTS DURING THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 240530Z4 VISIBLE SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES
OF 30 KNOTS. VISIBLE ANIMATION DEPICTS DEEP CONVECTION DEVELOPING
OVER THE VORTEX CENTER AND A WEAK BANDING FEATURE WRAPPING IN FROM
THE SOUTHEAST QUADRANT. A MID-LEVEL RIDGE EXTENDING OFF OF THE
NORTHWEST COAST OF AUSTRALIA SHOULD INFLUENCE THE SYSTEMS TRACK
THROUGH THE PERIOD. OUR FORECAST IS BASED ON THE UKMET SPECTRAL, THE
AVIATION RUN OF THE MRF, AND THE MEDIUM BETA ADVECTION MODEL BASED
OFF OF THE 240000Z6 NOGAPS RUN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
240600Z2 IS 12 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,

TROPICAL CYCLONE 11S (EDDY), APPROXIMATELY 500 NM WEST OF THE COCOS
ISLANDS, HAS TRACKED SOUTHWARD AT 07 KNOTS DURING THE PAST 6 HOURS.
THE WARNING POSITION IS BASED ON 241730Z7 INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT SATELLITE
INTENSITY ESTIMATES OF 30 AND 35 KNOTS. INFRARED ANIMATION DEPICTS
CYCLING DEEP CONVECTION OVER THE VORTEX CENTER AND IMPROVED

TROPICAL CYCLONE 11S (EDDY), LOCATED OVER THE SOUTH INDIAN OCEAN,
HAS TRACKED SOUTHWARD AT 09 KNOTS DURING THE PAST 6 HOURS.
THE WARNING POSITION IS BASED ON 250530Z5 VISIBLE SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT SATELLITE
INTENSITY ESTIMATES OF 45 KNOTS. VISIBLE ANIMATION AND MICROWAVE
IMAGERY CONTINUE TO DEPICT AN INCREASE IN COVERAGE AS NEW BURSTS OF
DEEP CONVECTION DEVELOP OVER THE LOW-LEVEL CIRCULATION CENTER.
A MID-LEVEL RIDGE EXTENDING OFF OF THE NORTHWEST COAST OF AUSTRALIA
SHOULD INFLUENCE THE SYSTEMS TRACK THROUGH THE PERIOD. OUR FORECAST

REMARKS:
270900Z8 POSITION NEAR 22.0S4 88.3E9.
TROPICAL CYCLONE 11S (EDDY), LOCATED APPROXIMATELY 735 NM SOUTHWEST
OF THE COCOS ISLANDS, HAS TRACKED SOUTH-SOUTHWESTWARD AT 8 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 270530Z7
VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 55 TO 65 KNOTS.
ANIMATED SATELLITE IMAGERY DEPICTS A PERSISTENT BANDING FEATURE. TC
11S WILL CONTINUE TO TRACK IN A SOUTH-SOUTHWESTERLY DIRECTION OVER
THE NEXT 12 HOURS, THEN BEGIN TO TURN GRADUALLY MORE WESTWARD AS THE
LOW TO MID-LEVEL RIDGE BUILDS SOUTH OF THE SYSTEM. TC 11S WILL
SLOWLY DECREASE IN INTENSITY THROUGH THE FORECAST PERIOD AS IT
APPROACHES INCREASING VERTICAL WIND SHEAR AND SLIGHTLY COOLER SEA
SURFACE TEMPERATURES. THE AVAILABLE DYNAMIC AIDS OF THE UK MET
GLOBAL (EGRR), NOGAPS, GFDN, AND AVIATION (AVN) MODELS ARE CLUSTERED
IN TWO GROUPS IN REGARD TO FORECAST TRACK. NGPS/AVN CONTINUE TO PULL
THE SYSTEM IMMEDIATELY WESTWARD WHILE EGRR/GFDN ARE INITIALLY
INDICATING A SOUTHERLY TRACK WITH A GRADUAL WESTWARD TURN BEYOND THE
24 HOUR PERIOD. OUR FORECAST IS BASED ON PERSISTENCE AND A BLEND OF
EGRR/GFDN THROUGH THE FIRST 24 HOURS LEANING TOWARD A CONSENSUS OF
ALL THE GLOBAL MODELS BY THE END OF THE FORECAST PERIOD
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270600Z5 IS 18 FEET.
NEXT WARNINGS AT 272100Z2 AND 280900Z9.

REMARKS:
272100Z2 POSITION NEAR 22.3S7 85.5E8
TROPICAL CYCLONE 11S (EDDY), LOCATED APPROXIMATELY 850 NM SOUTHWEST
OF THE COCOS ISLANDS, HAS TRACKED WESTWARD AT 14 KNOTS DURING THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 271730Z0 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT
SATELLITE INTENSITY ESTIMATES OF 35 KNOTS. ANIMATED SATELLITE
IMAGERY DEPICTS A SHEARED SYSTEM WITH REMAINING DEEP CONVECTION
FOUND 120 NM EAST OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). RECENT
TRMM AND SSMI PASSES OVER TC 11S FURTHER SUPPORT A STRONGLY SHEARED
SYSTEM. TC 11S WILL CONTINUE TO TRACK WEST-SOUTHWESTWARD UNDER THE
STEERING INFLUENCE OF A LOW TO MIDDLE LEVEL RIDGE SOUTH OF THE
SYSTEM OVER THE NEXT 12 HOURS. THE SYSTEM WILL THEN TURN SOUTH INTO
A BREAK IN THE LOW LEVEL RIDGE BEYOND 24 HOURS. TC 11S WILL CONTINUE
TO RAPIDLY WEAKEN THROUGH THE FORECAST PERIOD AS IT REMAINS IN A
STRONG VERTICAL WIND SHEAR ENVIRONMENT AND MOVES INTO COOLER SEA
SURFACE TEMPERATURES. THE AVAILABLE DYNAMIC AIDS CONSISTING OF THE
UK MET GLOBAL (EGRR), NOGAPS, GFDN, AND AVIATION (AVN) MODELS ARE IN
GOOD AGREEMENT ON THE FORECAST TRACK. OUR FORECAST IS BASED ON
PERSISTENCE AND A BLEND OF ALL THE DYNAMIC MODELS BY THE END OF THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 271800Z8 IS 18
FEET. NEXT WARNINGS AT 280900Z9 AND 282100Z3.//
