SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 10.6S 94.2E TO 12.2S 85.0E 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 082130Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 10.4S 93.3E. THE
SYSTEM IS MOVING WESTWARD AT 13 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.2S
94.3E, IS NOW LOCATED NEAR 10.4S 93.3E, APPROXIMATELY 245 NM
WEST-NORTHWEST OF COCOS ISLANDS. RECENT ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS CONSOLIDATING CONVECTION SHEARED OVER THE WESTERN
SEMI-CIRCLE OF A PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC). A 081731Z TRMM 85 GHZ MICROWAVE IMAGE REVEALS A DEFINED LLCC
WITH DEEP CONVECTIVE BANDING WRAPPING INTO THE CENTER. A 081455Z
ASCAT IMAGE DEPICTS A WELL-DEFINED CIRCULATION WITH 25 TO 30 KNOT
WINDS OVER THE SOUTHERN SEMI-CIRCLE. THE DISTURBANCE IS CURRENTLY
LOCATED EQUATORWARD OF THE UPPER-LEVEL SUBTROPICAL RIDGE UNDER LOW
TO MODERATE (10 TO 20 KT) VERTICAL WIND SHEAR WITH STRONG DIFFLUENCE
ALOFT. SEA SURFACE TEMPERATURES ARE ALSO FAVORABLE AT GREATER THAN
28 DEGREES CELSIUS. DYNAMIC MODEL GUIDANCE CONTINUES TO INDICATE THE
DEVELOPMENT OF A WEAK TROPICAL CYCLONE WITHIN THE NEXT 24 TO 36
HOURS. 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
092200Z.//

REMARKS:
092100Z POSITION NEAR 12.2S 85.7E.
TROPICAL CYCLONE (TC) 08S (EIGHT), LOCATED APPROXIMATELY 866 NM EAST-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE
IMAGERY DEPICTS CONSOLIDATING DEEP CONVECTION WITH SPIRAL BANDING
WRAPPING INTO A DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A
091614Z METOP-A 89 GHZ MICROWAVE IMAGE REVEALS IMPROVED CONVECTIVE
BANDING OVER THE NORTHERN SEMI-CIRCLE WRAPPING INTO THE CENTER. A
091615Z ASCAT PASS SHOWS A WELL-DEFINED CIRCULATION WITH 35 TO 40
KNOT WINDS IN THE CORE, WHICH SUPPORTS THE INITIAL INTENSITY
ASSESSMENT. THE CURRENT POSITION IS BASED ON THE AFOREMENTIONED
MICROWAVE IMAGE AND A TIGHT GROUPING OF AGENCY POSITION FIXES WITH
HIGH CONFIDENCE. UPPER-LEVEL ANALYSIS INDICATES A FAVORABLE
ENVIRONMENT WITH MODERATE TO STRONG VERTICAL WIND SHEAR (VWS), WHICH
IS BEING OFFSET BY THE SYSTEM'S EASTERLY MOTION AND INCREASING
OUTFLOW. TC 08S IS CURRENTLY TRACKING WEST-SOUTHWESTWARD UNDER THE
STEERING INFLUENCE OF THE SUBTROPICAL RIDGE (STR) TO THE SOUTH. BY
TAU 24, THE WESTERN EXTENSION OF THE STR IS FORECAST TO WEAKEN,
ALLOWING TC 08S TO TURN SLIGHTLY SOUTHWESTWARD. MODEL GUIDANCE
INDICATES A MID-LATITUDE TROUGH WILL MOVE IN TO THE SOUTH OF THE
SYSTEM NEAR TAU 36, WHICH WILL ENHANCE POLEWARD OUTFLOW ALLOWING FOR
RAPID INTENSIFICATION. THE COMBINED EFFECTS OF FAVORABLE UPPER LEVEL
CONDITIONS AND WARM SEA SURFACE TEMPERATURE WILL FURTHER SUPPORT A
PEAK INTENSITY OF 110 KNOTS BY TAU 96. THE STR WILL REORIENT IN THE
LATER TAUS AS THE MID-LATITUDE TROUGH MOVES EASTWARD, CAUSING TC 08S
TO TRACK SOUTHWARD. DUE TO THE GOOD AGREEMENT IN THE MODEL TRACKERS,
THERE IS HIGH CONFIDENCE IN THE OFFICIAL FORECAST TRACK, WHICH IS
POSITIONED CLOSE TO CONSENSUS AND FAVORS GFS AND ECMWF SOLUTIONS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z IS 10 FEET. NEXT WARNINGS

REMARKS:
100900Z POSITION NEAR 12.7S 83.1E.
TROPICAL CYCLONE 08S (COLIN), LOCATED APPROXIMATELY 737 NM EAST-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
SHOWS CENTRAL CONVECTION HAS STRUGGLED TO PERSIST OVER A WELL-
DEFINED LOW LEVEL CIRCULATION CENTER (LLCC). A DEEP BAND OF
CONVECTION REMAINS ALONG THE WESTERN AND NORTHERN PERIPHERY OF THE
LLCC, BUT HAS BEEN SLOWLY WEAKENING OVER THE PAST SIX HOURS. UPPER
LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH MODERATE TO
STRONG VERTICAL WIND SHEAR (VWS), WHICH IS BEING OFFSET BY THE
SYSTEM'S EASTERLY MOTION AND INCREASING OUTFLOW. TC 08S IS CURRENTLY
TRACKING WEST-SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF THE

REMARKS:
102100Z POSITION NEAR 14.3S 81.5E.
TROPICAL CYCLONE 08S (COLIN), LOCATED APPROXIMATELY 696 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 10
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE
IMAGERY DEPICTS STEADILY IMPROVING CENTRAL CONVECTION OVER A WELL-
DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 101652Z SSMIS
MICROWAVE IMAGE REVEALS SEVERAL FEEDER BANDS SPIRALING OUT FROM THE
SYSTEM CENTER AS WELL AS A LARGE BAND OF DEEP CONVECTION LOOSELY
WRAPPED ALONG THE WESTERN AND NORTHERN PERIPHERY OF THE LLCC. THE
INITIAL POSITION IS BASED ON THE IR ANIMATION AND EXTRAPOLATED FROM
THE SSMIS IMAGE WITH GOOD CONFIDENCE. THE INITIAL INTENSITY HAS BEEN
ASSESSED AT 45 KNOTS BASED ON CONGRUENT DVORAK INTENSITY ESTIMATES
FROM PGTW, KNES, FMEE, AND FIMP. UPPER LEVEL ANALYSIS INDICATES A
FAVORABLE ENVIRONMENT WITH LOW TO MODERATE (10-15 KNOTS) VERTICAL
WIND SHEAR (VWS), WHICH IS OFFSET BY IMPROVING UPPER LEVEL OUTFLOW.
TC 08S IS CURRENTLY TRACKING WEST-SOUTHWESTWARD UNDER THE STEERING
INFLUENCE OF THE SUBTROPICAL RIDGE (STR) TO THE SOUTH. BY TAU 24,
THE WESTERN EXTENSION OF THE STR IS FORECAST TO WEAKEN, ALLOWING TC
08S TO TURN SLIGHTLY MORE SOUTHWESTWARD. GRADUAL INTENSIFICATION IS
EXPECTED THROUGH TAU 48 DUE TO FAVORABLE UPPER LEVEL CONDITIONS AND
WARM SEA SURFACE TEMPERATURES. A TRANSITORY MID-LATITUDE TROUGH IS
EXPECTED TO PASS SOUTH OF THE SYSTEM NEAR TAU 72, WEAKENING THE STR
AND ALLOWING FOR TC 08S TO RECURVE BACK TO THE SOUTHEAST. DUE TO THE
GOOD AGREEMENT IN THE MODEL TRACKERS, THERE IS HIGH CONFIDENCE IN
THE OFFICIAL FORECAST TRACK, WHICH IS POSITIONED CLOSE TO THE MULTI-
MODEL CONSENSUS AND FAVORS THE ECMWF SOLUTION. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 101800Z IS 12 FEET. NEXT WARNINGS AT 110900Z AND

REMARKS:
110900Z POSITION NEAR 16.6S 80.0E.
TROPICAL CYCLONE (TC) 08S (COLIN), LOCATED APPROXIMATELY 721 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 10 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS
THE SYSTEM HAS BECOME MORE SYMMETRICAL AND HAS DEVELOPED A PINHOLE
10-NM EYE. THE INITIAL POSITION IS BASED ON THE EYE FIX WITH HIGH
CONFIDENCE. THE INITIAL INTENSITY IS BASED ON THE DVORAK ESTIMATE OF
65 KNOTS FROM PGTW. UPPER LEVEL ANALYSIS INDICATES A
FAVORABLE ENVIRONMENT WITH LOW TO MODERATE (10-15 KNOTS) VERTICAL
WIND SHEAR (VWS), WHICH IS OFFSET BY IMPROVING RADIAL OUTFLOW.
TC 08S IS CURRENTLY TRACKING WEST-SOUTHWESTWARD UNDER THE STEERING
INFLUENCE OF THE SUBTROPICAL RIDGE (STR) TO THE SOUTHEAST. IT IS
EXPECTED TO CREST THE RIDGE AROUND TAU 72 BEFORE RECURVING
SOUTHEASTWARD TOWARDS EXTRA TROPICAL TRANSITION BY TAU 120. GRADUAL
INTENSIFICATION IS EXPECTED THROUGH TAU 48 DUE TO FAVORABLE UPPER
LEVEL CONDITIONS AND WARM SEA SURFACE TEMPERATURES. A TRANSITORY
MID-LATITUDE TROUGH IS EXPECTED TO PASS SOUTH OF THE SYSTEM NEAR TAU
72, WEAKENING THE STR AND ALLOWING THE AFOREMENTIONED RECURVATURE.
DUE TO THE GOOD AGREEMENT IN THE MODEL TRACKERS, THERE IS HIGH
CONFIDENCE IN THE JTWC FORECAST TRACK, WHICH IS POSITIONED CLOSE TO
THE MULTI-MODEL CONSENSUS WITH SLIGHT BIAS TOWARDS THE ECMWF
SOLUTION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 110600Z IS 15 FEET. NEXT
WARNINGS AT 112100Z AND 120900Z. //

REMARKS:
112100Z POSITION NEAR 17.4S 78.8E.
TROPICAL CYCLONE 08S (COLIN), LOCATED APPROXIMATELY 717 NM SOUTH-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
DEPICTS A RAPIDLY INTENSIFYING SYSTEM WITH SEVERAL TIGHTLY WRAPPED
DEEP CONVECTIVE BANDS SPIRALING OUT FROM A 12-NM PINHOLE EYE. THE
INITIAL POSITION IS BASED ON THE EYE FIX WITH HIGH CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON CONGRUENT DVORAK INTENSITY ESTIMATES OF
115 KNOTS FROM PGTW AND FMEE. UPPER LEVEL ANALYSIS INDICATES A
FAVORABLE ENVIRONMENT WITH LOW TO MODERATE (10-15 KNOTS) VERTICAL
WIND SHEAR (VWS), WHICH IS OFFSET BY STRONG DUAL CHANNEL OUTFLOW
EVIDENT IN ANIMATED WATER VAPOR IMAGERY. TC 08S IS CURRENTLY

THE RIDGE AROUND TAU 48 BEFORE RECURVING SOUTHEASTWARD TOWARDS EXTRA-
TROPICAL TRANSITION BY TAU 120. FURTHER INTENSIFICATION IS EXPECTED
OVER THE NEXT 12 HOURS, BUT COOLING SEA SURFACE TEMPERATURES
THEREAFTER ARE EXPECTED TO GRADUALLY WEAKEN THE SYSTEM. A TRANSITORY

REMARKS:
120900Z POSITION NEAR 18.6S 77.8E.
TROPICAL CYCLONE (TC) 08S (COLIN), LOCATED APPROXIMATELY 745 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS THE SYSTEM HAS MAINTAINED SYMMETRY AND A
WELL-DEFINED EYE AS IT CONTINUES TO TRACK AROUND A DEEP-LAYERED
SUBTROPICAL RIDGE (STR) TO THE SOUTHEAST. THE MSI LOOP ALSO SHOWS
GOOD UPPER LEVEL DIVERGENCE WITH A VERY STRONG POLEWARD OUTFLOW
CHANNEL. THE INITIAL POSITION IS BASED WITH HIGH CONFIDENCE ON THE
15-NM EYE FEATURE. THE INITIAL INTENSITY IS BASED ON THE 120600Z
DVORAK ESTIMATE FROM PGTW. TC 08S IS EXPECTED TO CREST THE RIDGE
AROUND TAU 48 BEFORE RECURVING SOUTHEASTWARD AND TRANSITIONING INTO
AN EXTRA-TROPICAL LOW. THE CYCLONE IS EXPECTED TO MAINTAIN ITS
CURRENT INTENSITY OVER THE NEXT 12 HOURS AS LOW VERTICAL WIND SHEAR
(VWS) AND GOOD OUTFLOW PERSIST. AFTERWARDS, COOLING SEA SURFACE
TEMPERATURES AND INCREASING VWS ARE EXPECTED TO GRADUALLY WEAKEN THE
SYSTEM. A TRANSITORY MID-LATITUDE TROUGH IS EXPECTED TO PASS SOUTH OF
THE SYSTEM BEFORE TAU 48, WEAKENING THE STR AND ALLOWING THE
AFOREMENTIONED RECURVATURE. DUE TO THE GOOD AGREEMENT IN THE MODEL
TRACKERS, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK, WHICH
IS POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS WITH A SLIGHT BIAS
TOWARDS THE ECMWF SOLUTION RESULTING IN A TIGHTER RECURVATURE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120600Z IS 23 FEET. NEXT WARNINGS

REMARKS:
130900Z POSITION NEAR 23.1S 75.0E.
TROPICAL CYCLONE (TC) 08S (COLIN), LOCATED APPROXIMATELY 938 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT 14 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS THE SYSTEM CONTINUES TO DETERIORATE DUE TO COOLING SEA SURFACE
TEMPERATURES (SSTS) AND INCREASING VERTICAL WIND SHEAR (VWS). THE
INITIAL POSITION IS BASED ON THE ABOVE ANIMATION AND ON
CLOSELY-GROUPED AGENCY FIXES WITH FAIR CONFIDENCE. THE INITIAL
INTENSITY IS BASED ON CONGRUENT DVORAK ESTIMATES FROM PGTW AND KNES.
UPPER LEVEL ANALYSIS INDICATES TC 08S CONTINUES TO TRACK AROUND A
DEEP-LAYERED SUBTROPICAL RIDGE (STR) TO THE EAST. IT IS EXPECTED TO
CREST THE STR AROUND TAU 24 BEFORE RECURVING SOUTHEASTWARD AND
TRANSITIONING INTO AN EXTRA-TROPICAL LOW. THE SYSTEM IS EXPECTED TO
CONTINUE A GRADUAL WEAKENING TREND DUE TO THE COOLING SSTS AND
INCREASING VWS. A TRANSITORY MID-LATITUDE TROUGH IS EXPECTED TO PASS
SOUTH OF THE SYSTEM BEFORE TAU 24, WEAKENING THE STR AND ALLOWING THE
AFOREMENTIONED RECURVATURE. THERE IS TIGHT AGREEMENT AMONG THE MODEL
TRACKERS, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 130600Z IS 22 FEET. NEXT WARNINGS AT
132100Z AND 140900Z. //

140900Z POSITION NEAR 27.2S 73.3E.
TROPICAL CYCLONE 08S (COLIN), LOCATED APPROXIMATELY 1171 NM SOUTH OF
DIEGO GARCIA, HAS TRACKED SOUTHWARD AT 09 KNOTS OVER THE PAST SIX
HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A
FULLY EXPOSED LOW LEVEL CIRCULATION CENTER WITH A NEARLY COMPLETE
LOSS OF DEEP CONVECTION. MSI SHOWS THE OVERALL LOW LEVEL STRUCTURE
BECOMING LESS TIGHTLY WRAPPED IN THE PAST TWELVE HOURS AS THE SYSTEM
PROGRESSES OVER UNFAVORABLE SEA SURFACE TEMPERATURES (SSTS) (24
DEGREES CELSIUS). CURRENT MICROWAVE CROSS SECTIONS FOR TC 08S
INDICATE THE SYSTEM REMAINS A WARM CORE CIRCULATION, BUT MODEL
GUIDANCE INDICATES A SHIFT TO A SUBTROPICAL COLD CORE CIRCULATION IN
THE NEXT 12 TO 24 HOURS AS THE SYSTEM REMAINS OVER DIMINISHING SSTS.
THE MID-LATITUDE TROUGH TRACKING EASTWARD, TO THE SOUTH OF TC 08S,
HAS CAUSED THE SUBTROPICAL RIDGE (STR) TO SHIFT, BRINGING THE TRACK
MORE SOUTHWARD IN THE PAST FEW HOURS. AS THE TROUGH CONTINUES
EASTWARD, THE STR WILL FURTHER ADJUST CAUSING THE TRACK TO SHIFT TO
THE SOUTHEAST. ADDITIONALLY, THE UPPER LEVEL ENVIRONMENT WILL
DETERIORATE AS VERTICAL WIND SHEAR INCREASES ASSOCIATED WITH THE MID-
LATITUDE WESTERLIES. EXTRATROPICAL TRANSITION IS EXPECTED TO BE
COMPLETE BY TAU 24. BASED ON THE TIGHT GROUPING OF MODEL GUIDANCE,
THERE IS HIGH CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 140600Z IS 18 FEET. NEXT WARNINGS AT 142100Z.//
