1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 14.0S 67.7E TO 17.9S 64.2E
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
042030Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 14.4S
67.1E. THE SYSTEM IS MOVING SOUTHWESTWARD AT 11 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED
NEAR 13.7S 67.9E, IS NOW LOCATED NEAR 14.4S 67.1E, APPROXIMATELY 645
NM EAST-NORTHEAST OF MAURITIUS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY AND A 041721Z 89GHZ AMSU MICROWAVE IMAGE DEPICT A
CONSOLIDATING SYSTEM WITH DEEP CONVECTIVE BANDING OVER THE NORTHERN
SEMICIRCLE WRAPPING INTO A BROAD LOW LEVEL CIRCULATION CENTER. A
041722Z ASCAT IMAGE SHOWS A DEFINED CIRCULATION WITH 25 TO 30 KNOT
WINDS. THE UPPER LEVEL ENVIRONMENT IS FAVORABLE WITH STRONG
DIVERGENCE ALOFT DUE TO DUAL CHANNEL OUTFLOW AND LOW (10-15KTS)
VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES ARE FAVORABLE (28-
30C). GLOBAL MODELS ARE IN OVERALL AGREEMENT THAT THE SYSTEM WILL
TRACK WEST-SOUTHWESTWARD TO SOUTHWESTWARD OVER THE NEXT TWO DAYS
WITH STEADY INTENSIFICATION. 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 THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY

REMARKS:
051500Z POSITION NEAR 15.8S 64.3E.
TROPICAL CYCLONE (TC) 12S (TWELVE), LOCATED APPROXIMATELY 492 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHWESTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS TIGHTLY WRAPPED BANDING WITH CONVECTION CONTINUING TO
IMPROVE AROUND THE LOW LEVEL CIRCULATION CENTER (LLCC). THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE AND IS BASED ON A 051042Z
37GHZ SSMI MICROWAVE IMAGE. THE INITIAL INTENSITY OF 35 KNOTS IS
BASED ON DVORAK INTENSITY ESTIMATES OF T2.5 (35 KNOTS) FROM PGTW AND
FMEE. ENVIRONMENTAL ANALYSIS SHOWS TC 12S IS EXPERIENCING FAVORABLE
(5 TO 10 KNOT) VERTICAL WIND SHEAR ALONG WITH GOOD RADIAL OUTFLOW
WHICH CONTINUES TO IMPROVE. SEA SURFACE TEMPERATURES ARE ALSO
FAVORABLE FOR DEVELOPMENT, NEAR 30 DEGREES CELSIUS. TC 12S IS
TRACKING SOUTHWESTWARD WHILE UNDER THE INFLUENCE OF A SUBTROPICAL
RIDGE (STR) LOCATED TO THE NORTHEAST. THROUGH TAU 24, THE STR WILL
BUILD TO THE NORTHWEST. AS A RESULT, TC 12S WILL BEGIN TO TRACK
SOUTHEASTWARD BY TAU 24 AS IT INTENSIFIES. FAVORABLE SEA SURFACE
TEMPERATURES AND UPPER LEVEL OUTFLOW WILL ALLOW TC 12S TO REACH A
PEAK INTENSITY OF 105 KNOTS BY TAU 72. TC 12S WILL QUICKLY TRACK
SOUTHEASTWARD AND WILL BEGIN EXTRATROPICAL TRANSITION (ETT) BY TAU 72
AND COMPLETE ETT BY TAU 96. DYNAMIC MODEL GUIDANCE IS IN GOOD
AGREEMENT AND INDICATES A SOUTHWESTWARD TRACK FOLLOWED BY A TURN TO
THE SOUTHEAST. BASED ON GOOD MODEL AGREEMENT THERE IS HIGH CONFIDENCE
IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
051200Z IS 10 FEET. NEXT WARNINGS AT 052100Z, 060300Z, 060900Z AND
061500Z.

REMARKS:
052100Z POSITION NEAR 16.3S 64.2E.
TROPICAL CYCLONE (TC) 12S (FUNANI), LOCATED APPROXIMATELY 463 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS A RAPIDLY CONSOLIDATING SYSTEM
WITH SPIRAL BANDING WRAPPING INTO A CENTRAL DENSE OVERCAST FEATURE.
A 051439Z SSMIS 37GHZ COLOR MICROWAVE IMAGE (MI) SHOWS A MICROWAVE
EYE FEATURE SURROUNDED BY A CYAN RING, WHICH TYPICALLY SIGNALS AN
IMMINENT RAPID INTENSIFICATION PHASE. BASED ON THE MI, THERE IS GOOD
CONFIDENCE IN THE INITIAL POSITION. THE INITIAL INTENSITY IS
ASSESSED AT 45 KNOTS BASED ON THE EXCELLENT CONVECTIVE STRUCTURE,
CONSISTENT WITH A DVORAK INTENSITY ESTIMATE OF T3.0 (45 KNOTS) FROM
FIMP. ENVIRONMENTAL ANALYSIS INDICATES VERY FAVORABLE CONDITIONS
WITH STRONG DIVERGENCE ASSOCIATED WITH RADIAL OUTFLOW, LOW VERTICAL
WIND SHEAR (VWS) AND WARM SST (30C). TC FUNANI IS TRACKING SLOWLY
SOUTH-SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF A SUBTROPICAL
RIDGE (STR) POSITIONED TO THE EAST. AFTER TAU 12, A DEEP MIDLATITUDE
SHORTWAVE TROUGH IS FORECAST TO DEEPEN TO THE SOUTHWEST OF THE
SYSTEM, WHICH WILL REORIENT THE STR AND ALLOW THE SYSTEM TO
ACCELERATE SOUTHEASTWARD TO SOUTH-SOUTHEASTWARD THROUGH THE FORECAST
PERIOD. DUE TO THE EXCELLENT VENTING, TC 12S IS EXPECTED TO RAPIDLY
INTENSIFY THROUGH TAU 48 TO A PEAK INTENSITY OF 110 KNOTS. AFTER TAU
60, TC 12S SHOULD BEGIN EXTRA-TROPICAL TRANSITION (ETT) AS IT
INTERACTS WITH THE MIDLATITUDE WESTERLIES AND ENCOUNTERS INCREASING
VWS. THE SYSTEM IS FORECAST TO COMPLETE ETT BY TAU 96 AS IT BECOMES
EMBEDDED WITHIN THE MIDLATITUDE WESTERLIES AND GAINS FRONTAL
CHARACTERISTICS. AFTER TAU 96, TC FUNANI WILL REMAIN A STRONG COLD-
CORE EXTRATROPICAL LOW WITH STORM-FORCE WINDS. BASED ON GOOD MODEL
AGREEMENT, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051800Z IS 12 FEET. NEXT

REMARKS:
060300Z POSITION NEAR 16.7S 64.0E.
TROPICAL CYCLONE 12S (FUNANI), LOCATED APPROXIMATELY 438 NM EAST-
NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHWESTWARD AT
04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY INDICATES THE SYSTEM CONTINUES TO CONSOLIDATE AND
RAPIDLY INTENSIFY, WITH CONVECTIVE BANDING WRAPPING INTO A TIGHT
CENTRAL DENSE OVERCAST FEATURE. THE INITIAL POSITION IS PLACED WITH
HIGH CONFIDENCE BASED ON A MICROWAVE EYE FEATURE EVIDENT IN A 052332Z
SSMIS 89 GHZ MICROWAVE IMAGE. THE INITIAL INTENSITY IS ASSESSED WITH
MODERATE CONFIDENCE AT 50 KNOTS, HEDGED SLIGHTLY HIGHER THAN THE PGTW
DVORAK INTENSITY ESTIMATE OF T3.0 (45 KNOTS) IN LIGHT OF AUTOMATED
DVORAK ESTIMATES OF T3.5 (55 KNOTS) AND A SATCON ESTIMATE OF 55
KNOTS. ENVIRONMENTAL ANALYSIS REVEALS THE SYSTEM LIES IN AN AREA
HIGHLY FAVORABLE FOR RAPID INTENSIFICATION, WITH LOW (5-10 KNOTS)
VWS, VERY WARM SSTS (30 CELSIUS) AND STRONG RADIAL OUTFLOW BEING
PROVIDED BY AN UPPER LEVEL POINT SOURCE NEARBY. TC FUNANI IS
TRACKING SOUTHWARD ALONG THE WESTERN PERIPHERY OF A DEEP-LAYER
SUBTROPICAL RIDGE (STR) LOCATED TO THE EAST. TC FUNANI IS FORECAST
TO TURN MORE SOUTHEAST AND ACCELERATE OVER THE NEXT 24 HOURS AS THE
STR BEGINS TO REORIENT IN RESPONSE TO THE APPROACH OF AN UPPER LEVEL
TROUGH FROM THE WEST. TC 12S IS EXPECTED TO RAPIDLY INTENSIFY OVER
THE NEXT 48 HOURS AS RADIAL OUTFLOW CONTINUES AND BECOMES ENHANCED
BY A TAP INTO THE POLEWARD FLOW AHEAD OF THE DIVERGENT TROUGH,
PEAKING AT 105 KNOTS AT TAU 48. BEYOND TAU 48, INCREASING VWS AND
DECREASING SSTS WILL COMBINE TO PUT THE SYSTEM ON A WEAKENING TREND.
BY TAU 72, TC FUNANI BEGINS TO INTERACT DIRECTLY WITH THE BAROCLINIC
ZONE AND MID-LATITUDE WESTERLIES ALOFT AND BEGINS EXTRA-TROPICAL
TRANSITION (ETT). THE SYSTEM IS EXPECTED TO COMPLETE ETT BY TAU 96,
AS IT GAINS COLD CORE BAROCLINIC TRAITS. MODEL GUIDANCE IS IN
OVERALL GOOD AGREEMENT, WITH SOME MARGINAL SPREAD AFTER TAU 72, WITH
NAVGEM AND ECMWF DEFINING THE WESTERN AND EASTERN EDGE OF THE
ENVELOPE RESPECTIVELY. THE JTWC FORECAST LIES CLOSE TO THE
MULTIMODEL CONSENUS WITH HIGH CONFIDENCE. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 060000Z IS 14 FEET. NEXT WARNINGS AT 060900Z, 061500Z,
062100Z AND 070300Z. REFER TO TROPICAL CYCLONE 13S (THIRTEEN)

SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED
ENHANCED INFRARED (EIR) SATELLITE IMAGERY SHOWS THE SYSTEM CONTINUED
TO RAPIDLY DEEPEN AS RAIN BANDS WRAPPED TIGHTER INTO A SHARPLY
OUTLINED 12-NM EYE. THE INITIAL POSITION IS PLACED WITH HIGH
CONFIDENCE BASED ON THE EYE FEATURE IN THE EIR LOOP THAT LINED UP
PERFECTLY WITH A MICROWAVE EYE IN THE 1425Z SSMIS PASS. THE INITIAL
INTENSITY IS BASED ON THE DVORAK INTENSITY OF T5.0/90KTS FROM PGTW
AND KNES. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA
WITH LOW (5-10 KNOT) VERTICAL WIND SHEAR (VWS) AND ROBUST RADIAL
OUTFLOW WITH A STRONG POLEWARD BIAS. TC 12S IS TRACKING OVER WARM
WATERS (30 CELSIUS) ALONG THE WESTERN PERIPHERY OF A DEEP-LAYER
SUBTROPICAL RIDGE (STR) TO THE EAST AND IS FORECAST TO ACCELERATE IN
RESPONSE TO AN UPPER LEVEL TROUGH APPROACHING FROM THE SOUTHWEST. THE
FAVORABLE CONDITIONS WILL FUEL FURTHER INTENSIFICATION TO A PEAK OF
110 KNOTS BY TAU 24 AS POLEWARD OUTFLOW FURTHER IMPROVES AHEAD OF THE
MIDLATITUDE TROUGH. AFTERWARD, INCREASING VWS AND DECREASING SSTS
WILL CAUSE GRADUAL WEAKENING. CONCURRENTLY, TC 12S WILL BEGIN
EXTRATROPICAL TRANSITION, EVENTUALLY BECOMING A STRONG STORM-FORCE
COLD CORE LOW WITH AN EXPANDING WIND FIELD BY TAU 96. MODEL GUIDANCE
IS IN OVERALL GOOD AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC
TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061800Z IS 28
FEET. NEXT WARNINGS AT 070300Z, 070900Z, 071500Z AND 072100Z. REFER
TO TROPICAL CYCLONE 13S (GELENA) WARNINGS (WTXS32 PGTW) FOR SIX-

REMARKS:
070900Z POSITION NEAR 19.4S 66.5E.
TROPICAL CYCLONE 12S (FUNANI), LOCATED APPROXIMATELY 502 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS A THICK EYEWALL SURROUNDING A PINHOLE EYE. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE IN THE MSI
IMAGERY. THE INITIAL INTENSITY IS BASED ON A 070455Z SATCON ESTIMATE
OF 107 KTS AND IS BELOW THE PGTW AND KNES DVORAK CURRENT INTENSITY
ESTIMATES OF T6.0 (115 KTS). UPPER LEVEL ANALYSIS INDICATES THE
SYSTEM IS IN AN AREA WITH LOW (5-10 KNOT) VERTICAL WIND SHEAR (VWS)
AND ROBUST RADIAL OUTFLOW WITH A STRONG POLEWARD BIAS THAT IS
ALLOWING FOR CONTINUED INTENSIFICATION. TC 12S IS TRACKING OVER WARM

SOUTHEAST THROUGHOUT THE FORECAST IN RESPONSE TO AN UPPER LEVEL
TROUGH APPROACHING FROM THE SOUTHWEST. POLEWARD OUTFLOW WILL
INCREASE FURTHER AS TC 12S TAPS INTO THE APPROACHING MIDLATITUDE
TROUGH, ALLOWING FOR CONTINUED INTENSIFICATION TO 115 KTS BY TAU 12.
AFTER TAU 24, INCREASING VWS AND DECREASING SSTS WILL CAUSE GRADUAL

REMARKS:
071500Z POSITION NEAR 20.3S 67.1E.
TROPICAL CYCLONE 12S (FUNANI), LOCATED APPROXIMATELY 530 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHEASTWARD AT 11
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS TC 12S HAS MAINTAINED A THICK EYEWALL
SURROUNDING A SMALL EYE. THE INITIAL POSITION IS PLACED WITH HIGH
CONFIDENCE BASED ON THE EYE IN THE MSI IMAGERY. THE INITIAL
INTENSITY AGREES WITH MULTIAGENCY DVORAK CURRENT INTENSITY ESTIMATES
OF T6.0 (115 KTS) AND CLOSE TO A 070916Z SATCON ESTIMATE OF 119 KTS.
UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA WITH LOW (10-
15 KNOT) VERTICAL WIND SHEAR (VWS) AND ROBUST RADIAL OUTFLOW WITH A
STRONG POLEWARD BIAS THAT IS ALLOWING FOR CONTINUED INTENSIFICATION.
TC 12S IS TRACKING OVER WARM WATERS (26-28 DEGREES CELSIUS) ALONG
THE WESTERN PERIPHERY OF A DEEP-LAYER SUBTROPICAL RIDGE (STR) TO THE
EAST. TC 12S WILL ACCELERATE TO THE SOUTHEAST THROUGHOUT THE
FORECAST AS IT IS PULLED BY AN UPPER LEVEL TROUGH APPROACHING FROM
THE WEST. POLEWARD OUTFLOW WILL INITIALLY INCREASE AS TC 12S TAPS
INTO THE APPROACHING MIDLATITUDE TROUGH, ALLOWING FOR NEAR-TERM
INTENSIFICATION TO 120 KTS BY TAU 12. AFTERWARDS, INCREASING VWS,
DECREASING SSTS, AND DECREASING OUTFLOW AS TC 12S MOVES UNDER THE
WESTERLY JET, WILL CAUSE WEAKENING. BY TAU 48, TC 12S WILL BEGIN
EXTRATROPICAL TRANSITION, EVENTUALLY BECOMING A STRONG STORM-FORCE
COLD CORE LOW WITH AN EXPANDING WIND FIELD BY TAU 72. MODEL GUIDANCE
IS IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC TRACK
FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071200Z IS 26 FEET.

REMARKS:
072100Z POSITION NEAR 21.1S 68.2E.
TROPICAL CYCLONE (TC) 12S (FUNANI), LOCATED APPROXIMATELY 586 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD AT 12 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE
IMAGERY SHOWS THE SYSTEM HAS MAINTAINED ITS CONVECTIVE SIGNATURE AND
A SEMI-CLOUD FILLED BUT DEFINED 10-NM EYE. THE INITIAL POSITION IS
PLACED WITH HIGH CONFIDENCE BASED ON THE EYE FEATURE IN THE EIR LOOP
THAT LINED UP WELL WITH A MICROWAVE EYE IN THE 071725Z AMSU IMAGE.
THE INITIAL INTENSITY IS BASED ON THE DVORAK ESTIMATES OF T6.0/115KTS
FROM PGTW, KNES, AND FMEE. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM
IS IN AN AREA WITH LOW TO MODERATE (10-15 KNOT) VERTICAL WIND SHEAR
(VWS) OFFSET BY ROBUST RADIAL OUTFLOW WITH A STRONG POLEWARD BIAS. TC
12S IS TRACKING OVER WARM WATERS (30 CELSIUS) ALONG THE WESTERN
PERIPHERY OF A DEEP-LAYER SUBTROPICAL RIDGE (STR) TO THE EAST AND
WILL REMAIN ON THIS TRACK FOR THE DURATION OF THE FORECAST. THE
FAVORABLE CONDITIONS MAY ALLOW SLIGHT INTENSIFICATION TO A PEAK OF
120 KNOTS BY TAU 12 AS POLEWARD OUTFLOW FURTHER IMPROVES AHEAD OF
A MIDLATITUDE TROUGH APPROACHING FROM THE SOUTHWEST. AFTERWARD,
INCREASING VWS AND DECREASING SSTS WILL CAUSE GRADUAL WEAKENING. BY
TAU 48, TC 12S WILL BEGIN EXTRATROPICAL TRANSITION, EVENTUALLY
BECOMING A STORM-FORCE COLD CORE LOW WITH AN EXPANDING WIND FIELD BY
TAU 72. MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT, LENDING HIGH
CONFIDENCE TO THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 071800Z IS 56 FEET. NEXT WARNINGS AT 080300Z, 080900Z,
081500Z, AND 082100Z. REFER TO TROPICAL CYCLONE 13S (GELENA) WARNINGS

REMARKS:
080300Z POSITION NEAR 22.2S 69.3E.
TROPICAL CYCLONE 12S (FUNANI), LOCATED APPROXIMATELY 646 NM EAST
OF PORT LOUIS, MAURITIU, HAS TRACKED SOUTHEASTWARD AT 14 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (IR) IMAGERY
DEPICTS CURVED BANDING WRAPPING INTO A RAGGED 10 NM DIAMETER EYE,
WITH LITTLE CHANGE OVER THE PAST SIX HOURS. THE INITIAL POSITION IS
PLACED WITH HIGH CONFIDENCE BASED ON MULTI-AGENCY FIXES ON THE IR
EYE. THE INITIAL INTENSITY WAS MAINTAINED AT 115 KNOTS BASED ON
DVORAK CURRENT INTENSITY ESTIMATES OF T6.0 (115 KNOTS) FROM PGTW AND
KNES. THE ENVIRONMENT REMAINS GENERALLY FAVORABLE WITH ROBUST RADIAL
OUTFLOW AND LIGHT TO MODERATE VERTICAL WIND SHEAR (15-20 KNOTS),
HOWEVER, SEA SURFACE TEMPERATURES ARE MODERATING DEVELOPMENT AS
FUNANI CONTINUES TO TRACK POLEWARD. TC 12S IS TRACKING ALONG THE
SOUTHWESTERN PERIPHERY OF A DEEP-LAYER SUBTROPICAL RIDGE TO THE
EAST, AND THERE IS GOOD AGREEMENT AMONG ALL DYNAMICAL MODELS THAT
THIS TRACK MOTION WILL PERSIST THROUGHOUT THE FORECAST. GUIDANCE
INDICATES THERE IS STILL POTENTIAL FOR SLIGHT INTENSIFICATION OVER
THE NEXT 6 TO 12 HOURS, AFTER WHICH VWS WILL BEGIN INCREASING AS A
MID-LATITUDETROUGH APPROACHES AND SEA SURFACE TEMPERATURES CONTINUE
TO COOL. FUNANI IS EXPECTED TO BEGIN EXTRATROPICAL TRANSITION BY TAU
48, AND THIS TRANSITION WILL BE COMPLETE PRIOR TO TAU 72. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 080000Z IS 50 FEET. NEXT WARNINGS AT

082100Z POSITION NEAR 26.3S 73.4E.
TROPICAL CYCLONE (TC) 12S (FUNANI), LOCATED APPROXIMATELY 918 NM
EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD AT
24 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A RAPIDLY WEAKENING SYSTEM WITH DEEP
CONVECTION SHEARED OVER THE SOUTHERN SEMICIRCLE. A 081703Z AMSU
89GHZ MICROWAVE IMAGE SHOWS DEEP CONVECTIVE BANDING OVER THE
SOUTHERN SEMICIRCLE WITH A WELL-DEFINED LOW-LEVEL CIRCULATION
CENTER, WHICH SUPPORTS THE INITIAL POSITION WITH GOOD CONFIDENCE.
BASED ON THE MARKED WEAKENING TREND AND DECAYING STRUCTURE, THE
INITIAL INTENSITY IS ASSESSED AT 75 KNOTS, WHICH IS CONSISTENT WITH
A PGTW DVORAK CURRENT INTENSITY ESTIMATE OF 4.5 (77 KNOTS). TC 12S
IS ACCELERATING SOUTHEASTWARD WITHIN THE ENHANCED FLOW BETWEEN A
SUBTROPICAL RIDGE AND DEEP MIDLATITUDE TROUGH, AND IS FORECAST TO
TRACK SOUTHEASTWARD TO SOUTH-SOUTHEASTWARD THROUGH THE FORECAST
PERIOD WHILE UNDERGOING EXTRA-TROPICAL TRANSITION (ETT). THE SYSTEM
WILL CONTINUE TO RAPIDLY WEAKEN DUE TO STRONG VERTICAL WIND SHEAR
AND COOL SST (LESS THAN 24C) BUT SHOULD MAINTAIN GALE-FORCE WINDS AS
IT COMPLETES ETT AND GAINS FRONTAL CHARACTERISTICS NEAR TAU 36.
NUMERICAL MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT, THEREFORE,
THERE IS HIGH CONFIDENCE IN THE JTWC OFFICIAL FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081800Z IS 45 FEET. NEXT WARNINGS
