SUBJ/TROPICAL CYCLONE FORMATION ALERT 280451ZJAN2004//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 200 NM RADIUS OF 6.0S6 88.8E4 WITHIN THE NEXT 12 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 25 TO 30 KNOTS. METSAT IMAGERY AT 280430Z7 INDICATES THAT
A CIRCULATION CENTER IS LOCATED NEAR 5.4S9 88.8E4. THE SYSTEM IS
MOVING WESTWARD AT 05 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY NEAR 5.4S9 88.8E4,
HAS BEEN RELOCATED EAST NEAR 6.0S6 89.5E2, APPROXIMATELY 990NM EAST-
NORTHEAST OF DIEGO GARCIA. A RECENT MICROWAVE PASS AT 280015Z6
INDICATES THAT A LOW LEVEL CIRCULATION CENTER HAS CONTINUED TO
CONSOLIDATE AND IS NOW CO-LOCATED WITH THE DEEP CONVECTION WHICH
HAS SIGNIFICANTLY INCREASED OVER THE PAST 03 HOURS AND BECOME MORE
ORGANIZED, YET REMAINS CYCLIC. 200 MB ANALYSIS INDICATES MODERATE
UPPER LEVEL DIFFLUENCE AND WEAK TO MODERATE VERTICAL WIND SHEAR OVER
THE AREA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1005 MB. DUE TO
IMPROVED ORGANIZATION, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS HAS BEEN
UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
290500Z6.

TROPICAL CYCLONE (TC) 11S, LOCATED APPROXIMATELY
230 NM NORTHWEST OF THE COCOS ISLANDS, HAS TRACKED
SOUTH-SOUTHEASTWARD AT 10 KNOTS OVER THE PAST SIX HOURS.
THE WARNING POSITION IS BASED ON 291130Z6 MULTISPECTRAL
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS CYCLING
CONVECTION TO THE SOUTHWEST OF THE LOW LEVEL CIRCULATION
CENTER (LLCC). TC 11S IS BEING STEERED ALONG THE SOUTHWESTERN
PERIPHERY OF THE LOW TO MID-LEVEL RIDGE LOCATED NORTH AND
EAST OF THE SYSTEM. TC 11S IS FORECAST TO TRACK MORE POLEWARD
AFTER TAU 12 ALONG THE WESTERN PERIPHERY OF THE STEERING
RIDGE THROUGH THE REMAINDER OF THE FORECAST PERIOD. TC 11S
IS EXPECTED TO INTENSIFY AT A LESS THAN CLIMATOLOGICAL RATE
THROUGH THE FORECAST PERIOD DUE TO WEAK OUTFLOW ALOFT AND
WEAK TO MODERATE VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, NCEP GFS, AND UKMET EGRR ARE IN FAIR
AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON A
CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT

THE WARNING POSITION IS BASED ON 301130Z8 MULTISPECTRAL

ON 302330Z1 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35

THAT DEEP CONVECTION IS INCREASING OVER THE LOW-LEVEL CIRCULATION
CENTER. TC 11S IS CURRENTLY BEING STEERED BY A MID-LEVEL

REMARKS:
011500Z7 POSITION NEAR 19.0S0 94.9E2.
TROPICAL CYCLONE (TC) 11S (LINDA), LOCATED APPROXIMATELY 400 NM
SOUTH-SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 05 KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
011130Z6 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 AND 45 KNOTS.
ANIMATED MULTISPECTRAL IMAGERY DEPICTS AN EXPOSED LOW LEVEL CIRCULATION
CENTER WITH NO DEEP CONVECTION. TC 11S IS EXPECTED TO TRACK SOUTHWESTWARD
AND DISSIPATE OVER THE NEXT 24 TO 36 HOURS IN AN UNFAVORABLE UPPER LEVEL
ENVIRONMENT. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, NCEP GFS,
GFDN, AND UKMET EGRR ARE IN FAIR AGREEMENT WITH THIS SCENARIO. THIS
FORECAST IS BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011200Z4 IS 18 FEET. NEXT WARNINGS
AT 020300Z5 AND 021500Z8. REFER TO TROPICAL CYCLONE 09S (ELITA) WARNINGS
(WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO TROPICAL CYCLONE 10S
(FRANK) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
012100Z4 POSITION NEAR 19.5S5 94.7E0.
TROPICAL CYCLONE (TC) 11S (LINDA), LOCATED APPROXIMATELY 430 NM
SOUTH-SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 05 KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
011730Z2 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 25 AND 30 KNOTS.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 011503Z0 SSMI
MICROWAVE IMAGE REVEALS THAT THE LOW LEVEL CIRCULATION CENTER (LLCC)
OF TC 11S IS COMPLETELY EXPOSED WITH THE REMNANTS OF THE CONVECTION
DISPLACED TO THE SOUTH OF THE LLCC. TC 11S HAS TRACKED INTO AN
UNFAVORABLE ENVIRONMENT OF CONFLUENCE AND MODERATE VERTICAL SHEAR AND IS
NOT EXPECTED TO REGENERATE. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
NOGAPS, NCEP GFS, GFDN, AND UKMET EGRR ARE IN FAIR AGREEMENT WITH THIS
SCENARIO. THIS FORECAST IS BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC
AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011800Z0 IS 21 FEET. 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. REFER TO TROPICAL CYCLONE 09S (ELITA) WARNINGS (WTXS31 PGTW)
FOR TWELVE-HOURLY UPDATES. REFER TO TROPICAL CYCLONE 10S (FRANK) WARNINGS
(WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//
