MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT 261921Z OCT 04//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
130 NM EITHER SIDE OF A LINE FROM 8.5S3 54.6E5 TO 8.6S4 47.9E0
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 IM
AGERY AT 261730Z9 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 8.7S5 53.9E7. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 15
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.8S6
54.7E6 IS NOW LOCATED NEAR 8.7S5 53.9E7, APPROXIMATELY 340 NM
NORTHEAST OF MADAGASCAR. ENHANCED INFRARED SATELLITE IMAGERY
REVEALS A COMPACT LLCC WITH DEEP CONVECTION CONSOLIDATING OVER
THE LLCC. 200 MB ANALYSIS INDICATES AN ENVIRONMENT OF LOW TO
MODERATE VERTICAL WIND SHEAR AND MODERATE DIFFLUENCE ALOFT.
MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED AT 1002 MB. DUE TO THE IMPROVING
ORGANIZATION OF THE SYSTEM, 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 271930Z2.//

REMARKS:
281500Z6 POSITION NEAR 8.2S0 43.0E7.
TROPICAL CYCLONE (TC) 02S, LOCATED APPROXIMATELY 270 NM EAST-
SOUTHEAST OF DAR ES SALAAM, TANZANIA HAS TRACKED NORTHWESTWARD
AT 20 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS
BASED ON 281130Z5 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
35 AND 45 KNOTS. RECENT MULTISPECTRAL SATELLITE IMAGERY
DEPICTS ORGANIZED CYCLING CONVECTION AROUND AN ORGANIZED LOW
LEVEL CIRCULATION CENTER (LLCC). MULTISPECTRAL SATELLITE
IMAGERY AND A 280836Z7 TRMM PASS INDICATES THE LLCC IS EXPOSED
TO THE NORTHWEST OF THE DEEP CONVECTION. TC 02S IS FORECAST
TO TRACK WEST-NORTHWESTWARD ALONG THE NORTHWEST QUADRANT OF A
MID-LEVEL STEERING RIDGE AND MAKE LANDFALL ALONG THE WEST COAST
OF AFRICA IN 12 TO 24 HOURS. THE AVAILABLE DYNAMIC AIDS CONSIS-
TING OF NOGAPS, GFDN, NCEP GFS, UKMET EGRR, AFWA MM5 AND WBAR
ARE IN POOR AGREEMENT WITH THIS SCENARIO. DYNAMIC AIDS EXHIBIT
DIFFERENT SOLUTIONS TO THE STRUCTURE OF THE MID-LEVEL STEERING
RIDGE ROUGHLY CENTERED EAST OF MADAGASCAR AND VARY IN THE
EXTENT TO WHICH THE RIDGE BUILDS WESTWARD. THE INTENSITY OF TC
02S IS FORECAST TO DECREASE FOR THE REMAINDER OF THE FORECAST
PERIOD AS THE SYSTEM CONTINUES TO INTERACT WITH LAND AND
ENCOUNTER AN ENVIRONMENT OF INCREASED VERTICAL WIND SHEAR.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 281200Z3 IS 14 FEET. NEXT
WARNINGS AT 290300Z4 AND 291500Z7.//

TROPICAL CYCLONE (TC) 02S, LOCATED APPROXIMATELY 120 NM SOUTH-
EAST OF DAR ES SALAAM, TANZANIA, HAS TRACKED WESTWARD AT 16
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
282330Z8 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
25 AND 30 KNOTS. A 281505Z1 QUIKSCAT PASS INDICATES AN OPEN
WAVE TO THE WEST-NORTHWEST OF MADAGASCAR. RECENT ANIMATED WATER
VAPOR SATELLITE IMAGERY SHOWS THAT THERE IS NO LONGER ANY
CONVECTION ASSOCIATED WITH THE REMNANTS OF THIS SYSTEM. THE
REMNANTS OF TC 02S ARE FORECAST TO MOVE OVER LAND WITHIN THE
NEXT 12 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290000Z1 IS
14 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.//
