SUBJ/TROPICAL CYCLONE FORMATION ALERT/170921ZJAN2005//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 8.2S0 84.9E1 TO 10.4S5 81.8E7
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 30 TO 35 KNOTS. METSAT IMAGERY AT
170900Z7 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 8.6S4
84.5E7. THE SYSTEM IS MOVING SOUTHWESTWARD AT 06 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.1S8
85.8E1 IS NOW LOCATED NEAR 8.6S4 84.5E7, APPROXIMATELY 720 NM
EAST OF DIEGO GARCIA. ANIMATED SATELLITE IMAGERY REVEALS INC-
REASING CONVECTION OVER A DEVELOPING LOW LEVEL CIRCULATION CEN-
TER. UPPER LEVEL ANALYSIS INDICATES LOW TO MODERATE VERTICAL
WIND SHEAR AND WEAK POLEWARD OUTFLOW. MAXIMUM SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS EST-
IMATED TO BE NEAR 1002 MB. BASED ON IMPROVING 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
180930Z1.//

THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON 180530Z7 MULTI-
SPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATEL-
LITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS. RECENT ENHANCED
WATER VAPOR IMAGERY REVEALS AN INCREASE IN RADIAL OUTFLOW, HOWEVER
DEEP CONVECTION HAS WEAKENED SLIGHTLY DURING THE PAST FEW HOURS.
ANIMATED MULTISPECTRAL IMAGERY SHOWS THE LOW LEVEL CIRCULATION CENTER
IS LOCATED FURTHER EQUATORWARD THAN PREVIOUSLY FORECAST, AND THIS
WARNING REFLECTS A SLIGHT CHANGE IN THE INITIAL POSITION. TC 11S IS
FORECAST TO CONTINUE TRACKING SOUTHWESTWARD AROUND THE NORTHWEST

SYSTEM WILL INCREASE SLOWLY AS THE OUTFLOW IS EXPECTED TO REMAIN
NEUTRAL TO FAVORABLE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180600Z5 IS

CURRENT INTENSITY ESTIMATES OF 35 AND 45 KNOTS. RECENT ANIMATED WATER
VAPOR IMAGERY REVEALS A STEADY RATE IN THE POLEWARD OUTFLOW CHANNEL,
AND CONVECTION AROUND THE LOW LEVEL CIRCULATION CENTER HAS BECOME

OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON 191730Z1
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 45 KNOTS WITH A 05 KNOT DOWNWARD
ADJUSTMENT TO REFLECT LOWER DVORAK FINAL-T INTENSITY ESTIMATES AND
A WEAKENING TREND. RECENT ANIMATED WATER VAPOR IMAGERY INDICATES
UPPER LEVEL POLEWARD OUTFLOW. TC 11S IS FORECAST TO CONTINUE TRACKING
SOUTHWESTWARD AND MAINTAIN INTENSITY, THEN SLOWLY WEAKEN AS IT MOVES
INTO AN ENVIRONMENT OF INCREASED VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 191800Z9 IS 10 FEET. NEXT WARNINGS AT 200900Z1 AND 202100Z5.//

REMARKS:
200900Z1 POSITION NEAR 16.3S0 71.2E0.
TROPICAL CYCLONE (TC) 11S (DAREN) LOCATED APPROXIMATELY
885 NM EAST-NORTHEAST OF MAURITIUS ISLAND, HAS TRACKED
WEST-SOUTHWESTWARD AT 13 KNOTS OVER THE PAST 06 HOURS.
THE WARNING POSITION IS BASED ON 200530Z0 MULTISPECTRAL
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 35 KNOTS. RE-
CENT MICROWAVE IMAGERY INDICATES THE CONVECTION IS BE-
COMING DECOUPLED FROM THE LOW LEVEL CIRCULATION CENTER
(LLCC) AND IS PARTIALLY EXPOSED TO THE NORTH. ANIMATED
WATER VAPOR IMAGERY AND UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM IS BEGINNING TO ENCOUNTER A HIGHER VERTICAL
WIND SHEAR ENVIRONMENT. TC 11S IS FORECAST TO CONTINUE
TRACKING WEST-SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY
OF THE MID-LEVEL STEERING RIDGE. THE VERTICAL SHEAR AND
POLEWARD OUTFLOW OFFSET EACH OTHER AND TC 11S IS FORE-
CAST TO MAINTAIN INTENSITY FOR THE REMAINDER OF THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
200600Z8 IS 11 FEET. NEXT WARNINGS AT 202100Z5 AND
210900Z2. REFER TO TROPICAL CYCLONE 12S (ERNEST) WARN-
INGS (WTXS32 PGTW) FOR TWELVE HOURLY UPDATES.//
