THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.4S 79.4E
IS NOW LOCATED NEAR 10.4S 77.7E, APPROXIMATELY 360 NM EAST-SOUTHEAST
OF DIEGO GARCIA. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS SCATTERED DEEP CONVECTION DEVELOPING NEAR AN ELONAGED LOW
LEVEL CIRCULATION CENTER ALSO EVIDENT IN A 161423Z SSMIS PASS. THIS
DISTURBANCE LIES WELL TO THE WEST OF AN UPPER LEVEL ANTICYCLONE
CENTER, IN AN AREA OF MODERATE NORTHEASTERLY VERTICAL WIND SHEAR
AND FAVORABLE POLEWARD AND WESTWARD DIFFLUENCE ALOFT. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. BECAUSE THE
LLCC IS ELONGATED AND UPPER LEVEL CONDITIONS LESS THAN OPTIMAL, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS POOR.

SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 9.8S 77.8E TO 11.4S 87.4E WITH-
IN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY IS-
SUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS
IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT IMAGERY AT
190800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 10.2S
78.4E. THE SYSTEM IS MOVING SOUTHEASTWARD AT 05 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.2S 78.1E
IS NOW LOCATED NEAR 10.2S 78.4E, APPROXIMATELY 400 NM EAST-SOUTHEAST
OF DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES A
VERY SMALL, CONSOLIDATING SYSTEM WITH DEEP CONVECTIVE BANDING WEST
WRAPPING INTO THE NORTHERN QUADRANT. A 190247Z SSMIS IMAGE ALSO
SUPPORTS A TIGHTENING LOW LEVEL CIRCULATION CENTER (LLCC) WITH GOOD
CONVECTIVE BANDING OVER THE WESTERN SEMI-CIRCLE BUT WEAK DEEP CONV-
ECTIVE BANDING OVER THE EASTERN SEMI-CIRCLE. ANIMATED WATER VAPOR
IMAGERY DEPICTS FAIR POLEWARD OUTFLOW ENHANCED BY A MIDLATITUDE
SHORTWAVE TROUGH WITH A GENERALLY FAVORABLE ENVIRONMENT AND THE
OVERALL ENVIRONMENT IS FAVORABLE FOR FURTHER DEVELOPMENT WITH WEAK
VERTICAL WIND SHEAR AND WARM SST. SCATTEROMETER DATA INDICATED A
WELL-DEFINED LLCC WITH 25-30 KNOT WINDS. THEREFORE, MAXIMUM SUST-
AINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE
NEXT 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 200830Z.//

TROPICAL CYCLONE (TC) 03S (THREE), LOCATED APPROXIMATELY 465 NM EAST-
SOUTHEAST OF DIEGO GARCIA HAS TRACKED EASTWARD OVER THE PAST 06
HOURS. ANIMATED INFRARED IMAGERY SHOWS DEEP CONVECTION HAS DEVELOPED
OVER A TIGHTLY WRAPPED LOW LEVEL CIRCULATION CENTER (LLCC). TC 03S
HAS UNDERGONE SIGNIFICANT DEVELOPMENT OVER THE PAST 12 HOURS, WITH
SATELLITE DVORAK INTENSITY ESTIMATES REACHING 2.5/2.5 (PGTW AND FMEE)
AND 2.0/2.0 (KNES). THE TRACK FOR TC 03B HAS BEEN PREDOMINANTLY
INFLUENCED BY LOW TO MID LEVEL TROUGHING TO THE SOUTH AND SOUTHWEST

TROPICAL CYCLONE OUTLOOK FOR THE CENTRAL INDIAN OCEAN
Issued at 12:00pm WDT on Wednesday the 19th of November 2008
For the area south of LATITUDE 10 SOUTH between LONGITUDES 90 - 110 EAST

Cyclone advices are current for TC Anika, please refer to latest advice.

Full details available from Bureau of Meteorology
Ph 1300 659 210 or visit http://www.bom.gov.au

A second low near 10S 80E is expected to move eastwards over the next few days.
Model guidance suggests it could develop into a tropical cyclone in the next 24
to 48 hours and may move east of 90E during Friday.

Potential for a second tropical cyclone [excluding TC Anika] between 90-110 E:
Thursday : Low
Friday : Moderate
Saturday: Moderate

** NOTE: Development potential is an estimate of the probability of **
** tropical cyclone development within a 24 hour period. **
** LOW = 10% or less MODERATE = 20-40% HIGH = 50% or more **
