SUBJ/TROPICAL CYCLONE FORMATION ALERT 210851Z MAR 05//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 185
NM EITHER SIDE OF A LINE FROM 11.4S6 64.5E5 TO 17.1S9 58.8E1 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 20 TO 25 KNOTS. METSAT IMAGERY AT 210530Z1 INDI-
CATES THAT A CIRCULATION CENTER IS LOCATED NEAR 12.8S1 63.2E1. THE
SYSTEM IS MOVING SOUTHWESTWARD AT 09 KNOTS.
3. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.1S4
63.7E6 IS NOW LOCATED NEAR 12.8S1 63.2E1, APPROXIMATELY 665 NM
NORTHEAST OF LA REUNION. RECENT ANIMATED MULTISPECTRAL AND MICROWAVE
SATELLITE IMAGERY REVEALS DEEP CONVECTION AND SURFACE CLOUD LINES ARE
BEGINNING TO ROTATE AROUND A LOW LEVEL CIRCULATION CENTER (LLCC).
UPPER LEVEL ANALYSIS INDICATES THE LLCC IS SITUATED UNDERNEATH THE
NEAR EQUATORIAL RIDGE AXIS IN AN ENVIRONMENT OF LOW VERTICAL WIND
SHEAR AND VERY FAVORABLE DIVERGENCE. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
GOOD.
4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
220900Z3.//

REMARKS:
240900Z5 POSITION NEAR 20.7S9 58.8E1.
TROPICAL CYCLONE (TC) 24S (HENNIE), LOCATED APPROXIMATELY 80 NM EAST-
SOUTHEAST OF MAURITIUS, HAS SHIFTED DIRECTION AND IS NOW TRACKING
SOUTH-SOUTHEAST AT 09 KNOTS. RECENT ANIMATED ENHANCED WATER VAPOR
IMAGERY REVEALS A DECREASE IN POLEWARD OUTFLOW AND A WEAKENING OF
DEEP CONVECTION. DURING THE FORECAST PERIOD, TC 24S SHOULD CONTINUE
TRACKING POLEWARD AND SLOWLY WEAKEN AS IT MOVES INTO AN ENVIRONMENT
OF LESS FAVORABLE OUTFLOW AND INCREASED VERTICAL WIND SHEAR. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 240600Z2 IS 19 FEET. NEXT WARNINGS AT
242100Z9 AND 250900Z6.//
