Tropical Cyclone Hudah
WTXS21 PGTW 20000324 00:30z
SUBJ/TROPICAL CYCLONE FORMATION ALERT 240021Z MAR 00//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 16.3S0 96.7E2 TO 15.6S2 85.9E2
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 232330Z3 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 16.0S7 95.1E5. THE SYSTEM IS MOVING WESTWARD AT 15 KNOTS.
3. REMARKS: ANIMATED INFRARED SATELLITE IMAGERY INDICATES MODERATE
CONVECTION HAS BEGUN TO BUILD AND WRAP AROUND THE SYSTEM=S LOW LEVEL
CIRCULATION CENTER (LLCC). THOUGH SCATTEROMETER DATA AND SCARCE
SYNOPTIC REPORTS DO NOT YET INDICATE AN INTENSIFYING WIND FIELD,
ANIMATED WATER VAPOR IMAGERY INDICATE IMPROVED OUTFLOW ALOFT AND A
DECREASE IN VERTICAL SHEAR ACROSS THE REGION. THESE IMPROVING
CONDITIONS ARE EXPECTED TO ALLOW FURTHER INTENSIFICATION. SATELLITE
CURRENT INTENSITY ESTIMATES REMAIN AT 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED NEAR 1003 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS
IS NOW GOOD.

REMARKS:
241500Z2 POSITION NEAR 15.2S8 92.5E6.
THE AREA OF CONVECTION SOUTHWEST OF COCOS ISLAND, WHICH WAS THE
SUBJECT OF A TROPICAL CYCLONE FORMATION ALERT, HAS BECOME BETTER
ORGANIZED OVER THE PAST 12 HOURS AND IS EXPECTED TO INTENSIFY INTO A
TROPICAL CYCLONE WITHIN THE NEXT 12 HOURS. THE TROPICAL SYSTEM,
LOCATED APPROXIMATELY 295 NM SOUTHWEST OF COCOS ISLAND, HAS TRACKED
WESTWARD AT 10 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION
IS BASED ON 241130Z1 INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE INTENSITY ESTIMATES OF 30 KNOTS.
ANIMATED VISIBLE AND INFRARED IMAGERY DEPICT A RELATIVELY SMALL (100
NM IN AREAL EXTENT) SYSTEM. IMAGERY ALSO SHOWS A DEVELOPING CENTRAL
DENSE OVERCAST (CDO) OVER THE LOW-LEVEL CIRCULATION CENTER (LLCC)
AND A POSSIBLE BANDING FEATURE OVER THE NORTHWEST QUADRANT. IT
APPEARS THAT THE LLCC IS NEAR THE EASTERN EDGE OF THE CDO. 200 MB
ANALYSIS INDICATES THE UPPER-LEVEL RIDGE AXIS IS SITUATED JUST SOUTH
OF THE SYSTEM. A MID-LEVEL HIGH CENTERED NEAR 30S3 70E7, SHOULD
BUILD EASTWARD THROUGH THE PERIOD TO A POSITION NEAR 30S3 85E3. AS A
RESULT, TC 21S IS EXPECTED TO TRACK GENERALLY WESTWARD WITHIN THE
DOMINANT RIDGE REGION. TC IS EXPECTED TO INTENSIFY AT A NEAR
CLIMATOLOGICAL RATE THROUGH THE FORECAST PERIOD AS THE SYSTEM
CONTINUES TO TRACK EQUATORWARD OF THE UPPER-LEVEL RIDGE AXIS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241200Z9 IS 12 FEET. THIS WARNING

REMARKS:
291500Z7 POSITION NEAR 16.9S6 70.8E5.
TROPICAL CYCLONE (TC) 21S (HUDAH), LOCATED APPROXIMATELY 486 NM
EAST-NORTHEAST OF PORT MATHURIN, HAS TRACKED WEST-SOUTHWESTWARD AT
12 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
291130Z6 VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90
AND 115 KNOTS. ANIMATED VISIBLE AND INFRARED SATELLITE IMAGERY
DEPICT A 10 NM CLOUD-FILLED EYE WITH A BANDING FEATURE SOUTH OF THE
CENTRAL CONVECTION. THE 290438Z6 SPECIAL SENSOR MICROWAVE IMAGER
PASS INDICATES THAT THE STRONGEST CONVECTION IS IN THE SOUTHERN
PORTIONS OF THE EYEWALL. ANIMATED WATER VAPOR IMAGERY SHOWS THAT
OUTFLOW HAS REMAINED GOOD OVERALL EXCEPT IN THE WESTERN QUADRANT.
MODEL DATA CONTINUES TO FORECAST A WEAKENING OF THE MID-LEVEL HIGH,
CURRENTLY CENTERED NEAR 27.0S9 68.5E9, AND SHIFTS IT EASTWARD WITH
THE APPROACH OF A MID-LATITUDE TROUGH FROM SOUTHEAST AFRICA AFTER
THE 36-HOUR POINT. TC 21S IS EXPECTED TO TRACK UNDER THE STEERING
INFLUENCE OF THE AFOREMENTIONED MID-LEVEL RIDGE, WITHIN THE DOMINANT
RIDGE PATTERN (OR TROPICAL EASTERLY PATTERN) FOR THE NEXT 36 HOURS
BEFORE MOVING INTO THE WEAKNESS IN THE SUBTROPICAL RIDGE. THE SYSTEM
IS EXPECTED TO SLOWLY WEAKEN THROUGH THE PERIOD. MAXIMUM SIGNIFICANT

TROPICAL CYCLONE (TC) 21S (HUDAH), LOCATED APPROXIMATELY 560 NM
WEST OF MADAGASCAR, HAS TRACKED WESTWARD AT 11 KNOTS DURING THE PAST
6 HOURS. THE WARNING POSITION IS BASED ON 312330Z2 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 115 AND 127 KNOTS. A 312047Z7 PARTIAL
TROPICAL RAINFALL MEASURING MISSION (TRMM) PASS DEPICTED AN INTENSE,
SYMMETRIC SYSTEM WITH A 24 NM CLOUD FREE EYE. THE 85 GHZ IMAGE SHOWS
THAT THE EYEWALL COMPLETELY SURROUNDS THE LOW-LEVEL CIRCULATION
CENTER. ANIMATED INFRARED IMAGERY REVEALS A CONVECTIVE BANDING
FEATURE EXTENDING OVER THE SOUTHERN HALF OF THE SYSTEM. A MID-LEVEL
RIDGE SITUATED OVER MOZAMBIQUE IS EXPECTED TO BUILD OVER MADAGASCAR
DURING THE NEXT 24 HOURS. TC 21S (HUDAH) WILL THEN TAKE A MORE WEST-
NORTHWESTWARD TRACK THROUGH THE REMAINDER OF THE PERIOD. THE SYSTEM
IS EXPECTED TO INTENSIFY DURING THE NEXT 12 HOURS REACHING A PEAK
INTENSITY OF 125 KNOTS. THE TRMM PASS WAS USED TO ADJUST THE SIZE
(WIND RADII) OF THE SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
010000Z1 IS 30 FEET. NEXT WARNINGS AT 011500Z7 (DTG 011351Z1) AND

TROPICAL CYCLONE (TC) 21S (HUDAH), LOCATED APPROXIMATELY 400 NM EAST
OF ANTANAMBE, MADAGASCAR, HAS TRACKED WEST-NORTHWESTWARD AT 13 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 011130Z6
VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 127 KNOTS.
ANIMATED VISIBLE AND INFRARED IMAGERY REVEAL THAT TC 21S (HUDAH) HAS
STRENGTHENED OVER THE PAST 12 HOURS AND HAS A 21 NM ROUND EYE.
IMAGERY ALSO SHOWS THAT DEEP CONVECTION WITHIN THE EYEWALL HAS
INTENSIFIED, ESPECIALLY IN THE EASTERN QUADRANT OF THE SYSTEM. A
010538Z7 SPECIAL SENSOR MICROWAVE IMAGER PASS DEPICTS A SYMMETRIC
EYEWALL WITH A BANDING FEATURE WRAPPING AROUND THE EASTERN SIDE OF
THE SYSTEM INTO THE SOUTHERN QUADRANT OF THE SYSTEM. TC 21S (HUDAH)
IS FORECAST TO TRACK UNDER THE STEERING INFLUENCE OF THE MID-LEVEL
RIDGE BUILDING OVER MADAGASCAR, AND EXTENDING EAST-SOUTHEASTWARD
SOUTH OF THE SYSTEM. A 010601Z8 ERS2 SCATTEROMETER PASS SUPPORTS THE
INITIAL 35-KNOT WIND RADIUS, AND INDICATES THAT THE STRONGER WINDS
ARE CONFINED TO THE SOUTHERN PORTIONS OF THE SYSTEM. THE SYSTEM IS
EXPECTED TO INTENSIFY SLOWLY UNTIL MAKING LANDFALL NEAR THE 30-HOUR
POINT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011200Z4 IS 30 FEET.

INFRARED SATELLITE IMAGERY DEPICTS THAT THE EYE HAS BECOME CLOUD
FILLED OVER THE PAST 6 HOURS. ALTHOUGH THE CLOUD TOPS HAVE WARMED
SIGNIFICANTLY, THE SYSTEM HAS REMAINED WELL ORGANIZED. OUTFLOW
REMAINS IMPRESSIVE INDICATIVE OF OUTFLOW CHANNELS VISIBLE OVER THE
NORTHERN HALF OF THE SYSTEM. TC 21S IS EXPECTED TO TRACK MORE

TROPICAL CYCLONE (TC) 21S (HUDAH) HAS MOVED OFF THE NORTHWEST COAST
OF MADAGASCAR AND IS LOCATED APPROXIMATELY 34 NM NORTH OF MAJUNGA,
MADAGASCAR. TC 21S HAS TRACKED WEST-SOUTHWESTWARD AT 13 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 031130Z8 VISIBLE
AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 65 AND 77 KNOTS. A 030247Z6
SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS SHOWS THAT THE MAJORITY
OF THE CONVECTION IS SOUTH OF THE CENTER, WRAPPING INTO THE WESTERN
QUADRANT OF TC 21S. ANIMATED VISIBLE SATELLITE IMAGERY INDICATES
THAT THE LOW-LEVEL CIRCULATION CENTER (LLCC) HAS MOVED OFF THE
NORTHWEST COAST OF MADAGASCAR AND REMAINS TIGHTLY WRAPPED. INFRARED
IMAGERY SHOWS THAT THE DEEP CONVECTION HAS WEAKENED SINCE THE SSM/I
PASS, BUT SOME DEEP CONVECTION HAS BEGUN TO RE-DEVELOP OVER THE
LLCC. TC 21S IS EXPECTED TO CONTINUE TRACKING WEST-SOUTHWESTWARD
TOWARD A WEAKNESS IN THE RIDGE CREATED BY A MID-LATITUDE TROUGH
MOVING OFF OF THE SOUTH AFRICA COAST. TC 21S IS EXPECTED TO
INTENSIFY AT A NEAR CLIMATOLOGICAL RATE AS IT TRACKS WITHIN A
FAVORABLE ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031200Z6

070900Z6 POSITION NEAR 18.7S6 38.2E3.
TROPICAL CYCLONE (TC) 21S (HUDAH), LOCATED APPROXIMATELY 210 NM
EAST-NORTHEAST OF BEIRA, MOZAMBIQUE, HAS DRIFTED NORTH-NORTHWESTWARD
AT 03 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED
ON 070530Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 102 KNOTS.
ANIMATED INFRARED SATELLITE IMAGERY AND A 070358Z3 TROPICAL RAINFALL
MEASURING MISSION (TRMM) PASS DEPICT A 20 NM ROUND EYE THAT HAS
BECOME BETTER DEFINED IN THE PAST 6 HOURS. IMAGERY ALSO REVEALS
STRONGER CONVECTION CONFINED PRIMARILY TO THE SOUTHERN HALF OF THE
SYSTEM. ANIMATED WATER VAPOR IMAGERY CONTINUES TO SHOW GOOD OUTFLOW
ALOFT, AND SHOWS THAT THE MIDLATITUDE TROUGH IS LOCATED OFF THE
SOUTH AFRICAN COAST NEAR 35E8. TC 21S (HUDAH) IS CURRENTLY SITUATED
WITHIN A WEAKNESS IN THE SUBTROPICAL RIDGE WITH THE WESTERN HIGH
CENTERED NEAR 16S7 30E3, AND THE EASTERN HIGH CENTERED OVER SOUTHERN
MADAGASCAR. TC 21S IS DRIFTING WITHIN THE WEAKNESS, UNDER THE WEAK
STEERING INFLUENCE OF THE WESTERN HIGH. THE EASTERN RIDGE IS
FORECAST TO BUILD WESTWARD, SOUTH OF TC 21S, AFTER THE 12-24
HOUR POINT AS THE MIDLATITUDE TROUGH PROPAGATES EAST OF THE
MOZAMBIQUE CHANNEL. THIS WILL PROVIDE A MORE WESTWARD TO WEST-
NORTHWESTWARD STEERING INFLUENCE. TC 21S SHOULD INTENSIFY WITHIN A
FAVORABLE ENVIRONMENT UNTIL IT MAKES LANDFALL NEAR THE 36-HOUR
POINT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070600Z3 IS 22 FEET.
