WTXS21 PGTW 20031229 00:00z
SUBJ/TROPICAL CYCLONE FORMATION ALERT 282351Z DEC 03//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 9.7S6 65.2E3 TO 11.6S8 60.2E8
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 282330Z8 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 10.0S1 64.5E5. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT
12 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.3S2 66.3E5
IS NOW LOCATED NEAR 10.0S1 64.5E5, APPROXIMATELY 485 NM WEST-SOUTHWEST OF
DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY REVEALS THAT
CONVECTION IS BECOMING MORE ORGANIZED AROUND A LOW LEVEL CIRCULATION
CENTER. EARLIER MICROWAVE IMAGERY INDICATES AN INCREASE IN THE LOW LEVEL
CLOUD LINES. UPPER LEVEL ANALYSIS INDICATES WEAK VERTICAL WIND SHEAR AND
MODERATE DIFFLUENCE ALOFT. MAXIMUM ESTIMATED WINDS ARE 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 300000Z3.//

EXPECTED TO ENTER A WEAKNESS IN THE RIDGE IN 24 TO 36 HOURS AND
INCREASE INTENSITY. THE FORECAST IS BASED ON A BLEND OF NOGAPS,

SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 311730Z5 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT
SATELLITE INTENSITY ESTIMATES OF 55 AND 65 KNOTS. RECENT
MICROWAVE IMAGERY DEPICTS THE FORMATION OF A BANDING EYE

REMARKS:
030900Z2 POSITION NEAR 22.7S1 58.3E6.
TROPICAL CYCLONE (TC) 06S (DARIUS), LOCATED APPROXIMATELY 150 NM
EAST OF LA REUNION, HAS TRACKED SOUTHWARD AT 10 KNOTS OVER THE
PAST SIX HOURS. THE WARNING POSITION IS BASED ON 030530Z1
MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
CURRENT SATELLITE INTENSITY ESTIMATES OF 45, 55 AND 65 KNOTS. TC
06S IS FORECAST TO CONTINUE TRACKING POLEWARD OVER THE NEXT 48
HOURS. TC 06S IS FORECAST TO WEAKEN SLOWLY AND TRANSITION TO AN
EXTRATROPICAL LOW AS IT LINKS UP WITH THE FRONTAL BOUNDARY PASSING
SOUTH OF MADAGASCAR. TC 06S WILL COMPLETE EXTRATROPICAL TRANSITION
BY 48 HOURS AND ACCELERATE RAPIDLY TO THE SOUTHEAST. THE FORECAST
IS BASED ON A BLEND OF NOGAPS, UKMET (EGRR), GFDN, NCEP GFS AND
WBAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030600Z9 IS 16 FEET. NEXT
WARNINGS AT 032100Z6 AND 040900Z3. REFER TO TROPICAL CYCLONE 08S
