SUBJ/TROPICAL CYCLONE FORMATION ALERT 050951Z MAY 04//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS
POSSIBLE WITHIN 175 NM EITHER SIDE OF A LINE FROM
9.1S0 77.3E7 TO 9.1S0 69.0E5 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 050530Z3 INDICATES THAT A CIRCULATION
CENTER IS LOCATED NEAR 9.0S9 76.7E0. THE SYSTEM IS
MOVING WESTWARD AT 15 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED
NEAR 9.6S5 76.8E1, HAS BEEN RELOCATED ABOUT 1 DEGREE
FURTHER NORTH NEAR 9.0S9 76.7E0, APPROXIMATELY 270 NM
EAST-SOUTHEAST OF DIEGO GARCIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY INDICATES DEEP CONVECTION HAS BEGUN
TO CONSOLIDATE ONTO A DEVELOPING LOW LEVEL CIRCULATION
CENTER WITH GOOD POLEWARD OUTFLOW EVIDENT. UPPER LEVEL
ANALYSIS INDICATES THAT THE SYSTEM REMAINS EQUATORWARD
OF THE SUBTROPICAL RIDGE AXIS WITH FAVORABLE DIFFLUENCE
IN THE POLEWARD DIRECTION AND WEAK TO MARGINAL VERTICAL
WIND SHEAR FROM THE NORTHEAST. MAXIMUM SUSTAINED WINDS
ARE ESTIMATED AT 30 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED AT 1000 MB. DUE TO INCREASED ORGANIZATION,
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 061000Z7.//

TROPICAL CYCLONE (TC) 23S, LOCATED APPROXIMATELY 225 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT
11 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION
IS BASED ON 051130Z0 MULTISPECTRAL SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 35 KNOTS. DEEP CONVECTION
CONTINUES TO CONSOLIDATE OVER A DEVELOPING LOW LEVEL
CIRCULATION CENTER. SYNOPTIC REPORTS AT DIEGO GARCIA SHOW
STEADILY INCREASING SUSTAINED SURFACE WINDS WITH THE
051355Z9 OBSERVATION REPORTING 20 KNOTS AND A DROP OF OVER
2 MB OF PRESSURE IN 24 HOURS. TC 23S IS FORECAST TO CONTINUE
TRACKING WESTWARD ALONG THE NORTHERN PERIPHERY OF A LOW TO
MID LEVEL STEERING RIDGE TO THE SOUTH. TC 23S SHOULD
CONTINUE TO SLOWLY INTENSIFY AT LESS THAN A CLIMATOLOGICAL
RATE IN AN ENVIRONMENT OF GOOD OUTFLOW IN THE POLEWARD
DIRECTION OFFSET BY MARGINAL SHEAR FROM THE EAST-NORTHEAST.
THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN,
NCEP GFS, AND WBAI ARE IN FAIR AGREEMENT WITH THIS SCENARIO.
NOGAPS IS A SIGNIFICANT OUTLIER DUE TO POOR INITIALIZAITON.
THIS FORECAST IS BASED ON A BLEND OF PERSISTENCE AND A
CONSENSUS OF THE AVAILABLE DYNAMIC AIDS WITH LESS EMPHASIS
ON NOGAPS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051200Z8 IS

EITHER SIDE OF THE EQUATOR. BECAUSE THE AREA OF DEEP CONVECTION
IS IN AN ENVIRONMENT THAT IS FAIRLY FAVORABLE FOR DEVELOPMENT,
FURTHER LOW LEVEL CIRCULATIONS MAY DEVELOP BENEATH THIS AREA.
MAXIMUM SIGNIFICANT WAVEHEIGHT AT 061200Z9 IS 18 FEET.
THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT

REMARKS:
122100Z6 POSITION NEAR 11.9S1 67.8E1.  
TROPICAL CYCLONE (TC) 23S (JUBA), LOCATED APPROXIMATELY 800 NM
NORTHEAST OF MAURITIUS, HAS REGENERATED AND HAS TRACKED SOUTH-
WESTWARD AT 07 KNOTS OVER THE PAST 06 HOURS. THE WARNING
POSITION IS BASED ON 121730Z4 ENHANCED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 35 AND 45 KNOTS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND RECENT MICROWAVE IMAGERY REVEALS A WELL
DEFINED LOW LEVEL CIRCULATION CENTER THAT HAS RECOUPLED WITH THE
AREA OF DEEP CONVECTION. TC 23S IS FORECAST TO CONTINUE TRACKING
SOUTH-WESTWARD ALONG THE WESTERN PERIPHERY OF A LOW TO MID LEVEL
STEERING RIDGE TO THE EAST. TC 23S SHOULD SLOWLY INTENSIFY AT
LESS THAN A CLIMATOLOGICAL RATE IN AN ENVIRONMENT OF GOOD POLEWARD
OUTFLOW, SOUTH OF THE RIDGE AXIS FOR THE NEXT 24 HOURS. AFTER
24 HOURS, EXPECT TC 23S TO START WEAKENING AS IT ENTERS AN AREA OF
INCREASED VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS ARE IN
FAIR AGREEMENT WITH THIS SCENARIO. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 121800Z2 IS 11 FEET. NEXT WARNINGS AT 130900Z3 AND

IS BASED ON 130600Z0 MULTISPECTRAL SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 55 AND 65 KNOTS. ANIMATED VISIBLE
AND RECENT MICROWAVE SATELLITE IMAGERY REVEALS THAT TC 23S
BRIEFLY DEVELOPED A RAGGED EYE, HOWEVER THIS FEATURE IS
NO LONGER EVIDENT IN THE SATELLITE DATA. TC 23S IS
FORECAST TO CONTINUE TRACKING SOUTHWARD, BECOMING
SOUTH-SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF A LOW
TO MID LEVEL STEERING RIDGE TO THE EAST. TC 23S HAS
INTENSIFIED SIGNIFICANTLY OVER PAST 12 HOURS. THIS TREND
IS FORECAST TO SLOW WITH ONLY MODERATE FURTHER
INTENSIFICATION DURING THE NEXT 24 HOURS. AFTER 24 HOURS,
TC 23S IS FORECAST TO BEGIN WEAKENING AS IT ENTERS AN
AREA OF INCREASED VERTICAL WIND SHEAR AND BEGINS
INTERACTING WITH THE MID-LATITUDE WESTERLIES. THE
AVAILABLE DYNAMIC AIDS ARE IN POOR AGREEMENT WITH THIS
SCENARIO BASED ON POOR INITIALIZATION OF THE SYSTEM WITHIN
