SUBJ/TROPICAL CYCLONE FORMATION ALERT 100521ZFEB2003//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
170 NM EITHER SIDE OF A LINE FROM 12.6S9 64.7E7 TO 17.4S2 66.4E6
WITHIN THE NEXT 03 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF A NUMBERED TROPICAL CYCLONE WARNING AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 100230Z6 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 13.7S1 65.0E1. THE SYSTEM IS MOVING SOUTHWARD AT 04
KNOTS.
3. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.6S9
65.3E4 IS NOW LOCATED NEAR 13.7S1 65.0E1, APPROXIMATELY 580 NM
SOUTHWEST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY REVEALS PERSISTENT DEEP CONVECTION ASSOCIATED WITH A SMALL
LOW LEVEL CIRCULATION CENTER (LLCC). A RECENT QUIKSCAT PASS
INDICATES THAT THE SYSTEM REMAINS VERY SMALL. 200 MB ANALYSIS
INDICATES THAT THE DISTURBANCE CONTINUES TO MOVE UNDER FAVORABLE
OUTFLOW CONDITIONS ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. 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 UPGRADED TO GOOD.
4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
110530Z0.//

102100Z4 POSITION NEAR 16.0S7 64.1E1.
TROPICAL CYCLONE (TC) 17S, LOCATED APPROXIMATELY 460 NM EAST-
NORTHEAST OF MAURITIUS, HAS TRACKED SOUTH AT 11 KNOTS OVER THE PAST
6 HOURS. THE WARNING POSITION IS BASED ON 101730Z2 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 35 AND 45 KNOTS. A 101741Z4 SSM/I
PASS DEPICTS A WELL-DEFINED CIRCULATION WITH A DEEP CONVECTIVE BAND
IN THE NORTHERN SEMI-CIRCLE. TC 17S IS EXPECTED TO TRACK SOUTH-
SOUTHWESTWARD THROUGH 48 HOURS AS IT BEGINS TO INTERACT WITH TC 16S
(GERRY). THE AVAILABLE DYNAMIC AIDS, INCLUDING NGPS, UKMET (EGRR),
AND NCEP AVIATION (AVN) ARE IN POOR AGREEMENT WITH THIS SCENARIO.
AVN AND NOGAPS TRACK THE SYSTEM TO THE WEST, INDICATING NO
INTERACTION WITH TC 16S. BASED ON THE CLOSE PROXIMITY TO THE TWO
CYCLONES, OUR FORECAST IS BASED ON PERSISTENCE AND THE EGRR. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 101800Z0 IS 11 FEET. THIS WARNING

REMARKS:
130900Z3 POSITION NEAR 14.9S4 71.3E1.
TROPICAL CYCLONE (TC) 17S (HAPE), LOCATED APPROXIMATELY 475 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED NORTHEASTWARD AT 07 KNOTS OVER
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 130530Z2 VISIBLE
AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 77 KNOTS. RECENT MICROWAVE
IMAGERY REVEALED A WEAK BANDING EYE FEATURE ASSOCIATED WITH A SMALL
SYSTEM. TC 17S IS CURRENTLY TRACKING EQUATORWARD TOWARDS A WEAKNESS
IN THE LOW TO MID-LEVEL RIDGE NORTH OF THE SYSTEM. IN 12 TO 24
HOURS, THE SUB-TROPICAL RIDGE IS EXPECTED TO BUILD EAST-NORTHEAST OF
THE SYSTEM RESULTING IN A POLEWARD TRACK. TC 17S IS FORECAST TO
SLOWLY INTENSIFY THROUGH THE PERIOD AS OUTFLOW REMAINS MARGINAL. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF TLAPS, AFWA MM5, NOGAPS, GFDN,
UKMET (EGRR) AND THE NCEP AVIATION (AVN) MODELS ARE IN GOOD
AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON A BLEND OF
PERSISTENCE AND ALL AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 130600Z0 IS 20 FEET. NEXT WARNINGS AT 132100Z7 AND
140900Z4. REFER TO TROPICAL CYCLONE 14S (FIONA) WARNINGS (WTXS31
PGTW) FOR THE FINAL WARNING. REFER TO TROPICAL CYCLONE 16S (GERRY)
WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO TROPICAL
CYCLONE 18S (ISHA) WARNINGS (WTXS34 PGTW) FOR TWELVE-HOURLY

TROPICAL CYCLONE (TC) 17S (HAPE), LOCATED IN THE SOUTH INDIAN OCEAN,
HAS TRACKED EASTWARD AT 06 KNOTS OVER THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 131730Z5 INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 77 AND 90 KNOTS. TC 17S IS CURRENTLY TRACKING
EQUATORWARD TOWARDS A WEAKNESS IN THE LOW TO MID-LEVEL RIDGE NORTH
OF THE SYSTEM. IN THE NEXT 12 HOURS, THE SUB-TROPICAL RIDGE IS
EXPECTED TO BUILD EAST-NORTHEAST OF THE SYSTEM RESULTING IN A
POLEWARD TRACK. TC 17S IS FORECAST TO INTENSIFY SLIGHTLY IN THE
EARLY PERIOD AS IT TRACKS INTO THE RIDGE WEAKNESS AND ENCOUNTERS
FAVORABLE UPPER LEVEL OUTFLOW, AFTERWARDS THE SYSTEM IS EXPECTED TO
WEAKEN AS IT MOVES INTO A REGION OF HIGHER VERTICAL WIND SHEAR. THE

REMARKS:
140900Z4 POSITION NEAR 15.7S3 73.4E4.
TROPICAL CYCLONE (TC) 17S (HAPE), LOCATED IN THE SOUTH INDIAN OCEAN,
HAS TRACKED SOUTHEASTWARD AT 07 KNOTS OVER THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 140530Z3 INFRARED AND VISIBLE SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 65 KNOTS. ANIMATED SATELLITE IMAGERY REVEALS
UNFAVORABLE OUTFLOW OVER THE SYSTEM DUE TO ITS INTERACTION WITH TC
16S (GERRY). A RECENT MICROWAVE IMAGE SHOWS THAT THE DEEP CONVECTION
HAS DISSIPATED OVER THE CENTER, WHILE THERE CONTINUES TO BE A WELL-
DEVELOPED LOW LEVEL CIRCULATION CENTER. TC 17S IS CURRENTLY TRACKING
POLEWARD UNDER THE INFLUENCE OF THE SUB-TROPICAL RIDGE BUILDING
EAST-NORTHEAST OF THE SYSTEM. TC 17S IS FORECAST TO CONTINUE TO
WEAKEN THROUGH THE PERIOD AS IT INTERACTS WITH TC 16S AND ENCOUNTERS
UNFAVORABLE CONDITIONS. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
TLAPS, AFWA MM5, NOGAPS, GFDN, UKMET (EGRR) AND THE NCEP AVIATION
(AVN) MODELS ARE IN AGREEMENT WITH THIS SCENARIO, BUT DIFFER
SLIGHTLY ON THE DEGREE OF INTERACTION WITH TC 16S. OUR FORECAST IS

REMARKS:
150900Z5 POSITION NEAR 21.1S4 76.9E2.
TROPICAL CYCLONE (TC) 17S (HAPE), LOCATED APPROXIMATELY 800 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS ACCELERATED RAPIDLY DURING THE
PAST 12 HOURS AND IS FURTHER SOUTH AND EAST THAN FORECASTED
PREVIOUSLY. TC 17S HAS TRACKED SOUTHEASTWARD AT 23 KNOTS OVER THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 150530Z4 VISIBLE
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON A SATELLITE
CURRENT INTENSITY ESTIMATE OF 35 KNOTS AND A 150117Z5 QUIKSCAT PASS.
ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS A COMPLETELY EXPOSED LOW
LEVEL CIRCULATION CENTER. TC 17S IS FORECAST TO DISSIPATE AS A
SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 12 HOURS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 150600Z2 IS 16 FEET. THIS IS THE FINAL
WARNING ON THIS SYSTEM BY THE ALTERNATE JOINT TYPHOON WARNING CENTER
(FLENUMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION. REFER TO TROPICAL CYCLONE 16S (GERRY) WARNINGS (WTXS32
