1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
110 NM EITHER SIDE OF A LINE FROM 10.9S0 62.3E1 TO 12.8S1 58.4E7
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 020716Z6 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 11.1S3 61.8E5. THE SYSTEM IS MOVING WEST-
SOUTHWESTWARD AT 05 KNOTS.
2. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.7S9 62.7E5 IS NOW
LOCATED NEAR 11.1S3 61.8E5, APPROXIMATELY 700 NM EAST-NORTHEAST OF
ANTALAHA, MADAGASCAR. ANIMATED VISIBLE AND INFRARED SATELLITE
IMAGERY DEPICT IMPROVED ORGANIZATION OVER THE PAST 6 HOURS WITH
INCREASED CONVECTIVE BANDING. A 020449Z9 SPECIAL SENSOR MICROWAVE
IMAGER PASS DEPICTS A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC) EAST OF THE DEEP CONVECTION. THE 200 MB ANALYSIS SHOWS THAT
THE AREA IS UNDER THE SUBTROPICAL RIDGE AXIS AND HAS GOOD OUTFLOW.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE
POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS NOW GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
030930Z5.//

022100Z5 POSITION NEAR 11.4S6 60.3E9.
TROPICAL CYCLONE (TC) 04S HAS DEVELOPED APPROXIMATELY 660 NM EAST OF
THE NORTHERN TIP OF MADAGASCAR OVER THE SOUTH INDIAN OCEAN. TROPICAL
CYCLONE (TC) 04S HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 021730Z3 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 35 KNOTS. A 021726Z8 SPECIAL SENSOR
MICROWAVE IMAGER (SSM/I) PASS DEPICTED A PRIMARY BAND WRAPPING IN
TOWARDS THE LOW-LEVEL CIRCULATION CENTER FROM THE NORTHWEST. THE
SOUTH SEMI-CIRCLE, HOWEVER, IS VIRTUALLY DEEP CONVECTION FREE. MID-
LEVEL RIDGE EXTENDING EAST FROM SOUTHERN MADAGASCAR ALONG 25S7
SHOULD WEAKEN BY MID PERIOD WITH AN APPROACH OF A MID-LATITUDE
SYSTEM CURRENTLY OVER SOUTH AFRICA. TC 04S IS FORECAST TO TRACK
SOUTHWESTWARD THROUGH THE PERIOD. THE SYSTEM SHOULD INTENSIFY
AS IT TRACKS BENEATH THE SUBTROPICAL RIDGE. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 021800Z1 IS 12 FEET. THIS WARNING SUPERSEDES AND CANCELS

TROPICAL CYCLONE (TC) 04S (ANDO), LOCATED EAST OF MADAGASCAR IN THE
SOUTH INDIAN OCEAN, HAS TRACKED SOUTH-SOUTHWESTWARD AT 06 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 051730Z6
INFRARED SATELLITE IMAGERY AND A 051716Z0 SPECIAL SENSOR MICROWAVE
IMAGER (SSM/I). THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 115 AND 127 KNOTS. THE SSM/I IMAGE DEPICTS A
PRIMARY BAND OVER THE SOUTHERN QUADRANTS AND A 20 NM CONCENTRIC
EYEWALL. ANIMATED INFRARED SATELLITE IMAGERY CONTINUES TO DEPICT A
WELL-ORGANIZED, SYMMETRIC SYSTEM. TC 04S SHOULD REMAIN IN A WEAKNESS
CREATED BY A QUASI-STATIONARY LONGWAVE TROUGH, SITUATED OVER SOUTH
AFRICA, THROUGH THE FORECAST PERIOD. THEREFORE, TC 04S IS FORECAST
TO TRACK GENERALLY SOUTHWARD THROUGH THE PERIOD. LITTLE CHANGE IN
INTENSITY IS FORECAST OVER THE NEXT 24 HOURS. AFTERWARDS, THE SYSTEM
SHOULD BEGIN A SLOW WEAKENING TREND. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 051800Z4 IS 20 FEET. NEXT WARNINGS AT 060900Z5 (DTG 060752Z0) AND

082100Z1 POSITION NEAR 25.5S2 50.7E2.
TROPICAL CYCLONE (TC) 04S (ANDO), LOCATED APPROXIMATELY 210 NM EAST
OF TOLANARO, MADAGASCAR IN THE SOUTH INDIAN OCEAN, HAS TRACKED
SOUTH-SOUTHWESTWARD AT 04 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 081730Z9 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 55 TO 65 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY DEPICT A
PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
CONVECTION SOUTHEAST. IMAGERY SHOWS THAT TC 04S HAS WEAKENED RAPIDLY
OVER THE PAST 12 HOURS. THE 200 MB ANALYSIS SHOWS A TROUGH WEST OF
THE SYSTEM WITH EASTERLY FLOW OVER THE LLCC. TC 04S (ANDO) SHOULD
TRACK SOUTH-SOUTHWESTWARD WITHIN A WEAKNESS CREATED BY A SLOW MOVING
MID-LATITUDE TROUGH, SITUATED OFF THE SOUTHEAST COAST OF AFRICA,
THROUGH THE FORECAST PERIOD. THE STORM SHOULD CONTINUE TO WEAKEN
UNDER INCREASING VERTICAL WIND SHEAR, AND BEGIN EXTRA-TROPICAL
TRANSITION NEAR THE END OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 081800Z7 IS 20 FEET. REFER TO WWIO31 RJTX FOR
ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 090900Z8 (DTG
090752Z3) AND 092100Z2 (DTG 091952Z6). REFER TO TROPICAL CYCLONE
05S (BINDU) WARNINGS (WTXS32 PGTW)FOR TWELVE-HOURLY UPDATES.
