SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 200 NM RADIUS OF 13.1S 63.1E 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 270600Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 13.1S 63.2E. THE SYSTEM IS
MOVING NORTH-NORTHWESTWARD AT 10 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.6S
64.0E, IS NOW LOCATED NEAR 13.1S 63.2E, APPROXIMATELY 645 NM WEST
SOUTHWEST OF DIEGO GARCIA. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THAT THE SYSTEM HAS SLIGHTLY CONSOLIDATED OVER THE
LAST 6 HOURS WITH FORMATIVE BANDING BEGINNING TO WRAP INTO THE LOW
LEVEL CIRCULATION CENTER (LLCC). 270308Z SSMIS AND 270500Z METOP-A
MICROWAVE IMAGES DEPICT THE BULK OF THE CONVECTION ON THE NORTHWEST
SIDE OF THE LLCC. UPPER LEVEL ANALYSIS SHOWS A FAVORABLE ENVIRONMENT
FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR AND GOOD OUTFLOW
MECHANISMS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000
MB. DUE TO THE INCREASED CONSOLIDATION OF THE LLCC, THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24
HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
280930Z.//

REMARKS:
272100Z POSITION NEAR 12.8S 63.6E.
TROPICAL CYCLONE (TC) 09S (NINE), LOCATED APPROXIMATELY 639 NM WEST-
SOUTHWEST OF DIEGO GARCIA, HAS TRACKED NORTHEASTWARD AT 03 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
THE SYSTEM HAS DEEPENED AND CONSOLIDATED AFTER IT COMMENCED ON A
CLOCKWISE LOOPING MOTION. THE INITIAL POSITION IS BASED ON THE ABOVE
ANIMATION AND ON RECENT MICROWAVE PASSES WITH FAIR CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON AN OVERALL ASSESSMENT OF DVORAK
ESTIMATES FROM PGTW, KNES, AND FMEE. UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM IS IN THE VICINITY OF THE RIDGE AXIS IN AN AREA OF LIGHT
TO MODERATE (10-20 KNOT) VERTICAL WIND SHEAR (VWS) THAT IS OFFSET BY
EXCELLENT RADIAL OUTFLOW. THE CYCLONE HAS BEGUN TO TRACK UNDER THE
INFLUENCE OF A BUILDING NEAR-EQUATORIAL RIDGE (NER) TO THE NORTH AS
THE PREVIOUS STEERING MECHANISM - THE SUBTROPICAL RIDGE TO THE
SOUTHWEST - HAS WEAKENED AND RECEDED WESTWARD. TC 09S IS EXPECTED TO
SLOWLY GAIN MOMENTUM AND TRACK EAST-NORTHEASTWARD ALONG THE SOUTHERN
PERIPHERY OF THE NER. A FAVORABLE UPPER LEVEL ENVIRONMENT, IN
ADDITION TO WARM ALONG-TRACK SEA SURFACE TEMPERATURES (SSTS), WILL
PROMOTE STEADY INTENSIFICATION. AFTER TAU 36, THE SYSTEM MAY UNDERGO
RAPID INTENSIFICATION AS THE INITIAL EXPOSURE TO THE PREVAILING
WESTERLIES THAT ARE ALSO IN-PHASE WITH THE PROJECTED STORM MOTION,
FURTHER ENHANCES POLEWARD OUTFLOW. AFTER TAU 72, INCREASING VWS AND
COOLING SSTS WILL BEGIN TO ERODE THE SYSTEM. THE AVAILABLE NUMERIC
GUIDANCE IS IN UNUSUALLY GOOD AGREEMENT FOR AN INITIAL FORECAST
CONSIDERING THE TRACK UNCERTAINTY IN THE CYCLONES LOOPING MOTION. IN
VIEW OF THIS, THERE IS LOW CONFIDENCE IN THE INITIAL PORTION OF THE
FORECAST WITH HIGHER CONFIDENCE TOWARDS THE EXTENDED PORTION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 271800Z IS 10 FEET. NEXT WARNINGS AT
280900Z AND 282100Z. REFER TO TROPICAL CYCLONE 08S (DIAMONDRA)
WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
280300Z POSITION NEAR 13.4S 64.2E.

REMARKS:
281500Z POSITION NEAR 14.4S 65.0E.
TROPICAL CYCLONE 09S (EUNICE), LOCATED APPROXIMATELY 622 NM
SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTHEASTWARD AT 04 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL (MSI) SATELLITE
REVEALS THAT TC 09S HAS FURTHER DEEPENED AND DEVELOPED A VISIBLE
12NM EYE. THE INITIAL POSITION IS BASED ON THE ABOVE ANIMATION AND
ON RECENT MICROWAVE PASSES WITH VERY GOOD CONFIDENCE. THE INITIAL
INTENSITY IS SLIGHTLY HIGHER THAN THE AGREEING DVORAK ESTIMATES FROM
PGTW, KNES, AND FMEE WHICH ARE HELD SLIGHTLY LOW DUE TO CONSTRAINTS
IN THE DVORAK TECHNIQUE. OVER THE PAST 24 HOURS, THE SYSTEM HAS
INCREASED IN INTENSITY BY OVER 3O KTS AND 2 DVORAK T-NUMBERS,
SIGNALING THAT TC EUNICE HAS UNDERGONE RAPID INTENSIFICATION. UPPER
LEVEL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA OF LIGHT (10 KNOT)
VERTICAL WIND SHEAR (VWS) AND EXCELLENT OUTFLOW CHANNELS. THE CYCLONE
CONTINUES TO TRACK TO THE SOUTHEAST UNDER THE INFLUENCE OF A
BUILDING NEAR-EQUATORIAL RIDGE (NER) TO THE NORTHWEST. OVER THE NEXT
72 HOURS, EXPECT TC 09S TO CONTINUE TO TRACK TO THE SOUTHEAST DUE TO
THE BUILDING NER. ADDITIONALLY, INTENSIFICATION IS FORECAST AS THE
SYSTEM WILL MOVE IN-PHASE WITH THE VWS AND WILL BE FUELED BY
CONTINUAL GOOD OUTFLOW AND CONDUCIVE WARM WATERS. BEYOND TAU 72,
EXPECT THE SYSTEMS TRACK TO BEGIN TO FLATTEN OUT AND GAIN A MORE
WESTERLY COMPONENT AS THE NER ELONGATES AND REMAINS FAIRLY STRONG.
AS THE SYSTEM TRACKS ALONG 20 DEGREES SOUTH, EXPECT MILD WEAKENING
AS THE OCEAN HEAT CONTENT BEGINS TO WANE WITH TC EUNICE BEGINNING
DISSIPATION BY THE END OF THE FORECAST PERIOD. THE AVAILABLE DYNAMIC
NUMERIC MODEL GUIDANCE IS IN TIGHT AGREEMENT LENDING HIGH CONFIDENCE
TO THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
281200Z IS 25 FEET. NEXT WARNINGS AT 290300Z AND 291500Z. REFER TO

REMARKS:
290300Z POSITION NEAR 15.3S 65.9E.
TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 569 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-
SOUTHEASTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE (EIR) REVEALS PULSATING DEEP CENTRAL CONVECTION
CONSOLIDATING AROUND A SMALL 7NM EYE. A 290000Z SSMIS MICROWAVE PASS
SHOWS THE OVERALL STRUCTURE HAS REMAINED TIGHTLY WRAPPED OVER THE
PAST 12 HOURS WHILE NOT SIGNIFICANTLY INCREASING. THE CURRENT
POSITION IS BASED UPON THE SMALL EYE FEATURE OBSERVED IN THE EIR
LOOP WITH GOOD CONFIDENCE. THE CURRENT INTENSITY OF 90 KNOTS IS
BASED UPON THE CURRENT STRUCTURE OF THE SYSTEM AS WELL AS DVORAK
INTENSITY ESTIMATES OF THE SAME VALUE. UPPER LEVEL ANALYSIS REVEALS
AN OVERALL FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND
SHEAR (VWS) AND STRONG POLEWARD AND EQUATORWARD OUTFLOW. TC EUNICE
IS SLOWLY TRACKING EAST ALONG A NEAR EQUATORIAL RIDGE (NER) TO THE
NORTH OF THE SYSTEM. THE CYCLONE IS FORECAST TO SLOWLY TRACK TO THE
SOUTHEAST THROUGH TAU 48 AS THE NER MODIFIES. AFTER TAU 48, THE NER
IS EXPECTED TO BECOME MORE EAST-WEST ORIENTED ALLOWING FOR THE
SYSTEM TO TAKE A MORE EASTWARD TRACK. FURTHER INTENSIFICATION IS
EXPECTED THROUGH TAU 48 AS A FAVORABLE UPPER-LEVEL ENVIRONMENT AND
WARM SEA SURFACE TEMPERATURES PERSIST. AFTER WHICH, INCREASING SHEAR
AND MARGINAL SEA SURFACE TEMPERATURES WILL INDUCE A SLOW WEAKENING
PROCESS THROUGH THE REMAINDER OF THE FORECAST PERIOD. NUMERIC MODEL
GUIDANCE REMAINS IN GOOD AGREEMENT WITH THE FORECAST TRACK;
THEREFORE, THE FORECAST TRACK IS POSITIONED CLOSE TO MULTI-MODEL
CONSENSUS WITH HIGH CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
290000Z IS 26 FEET. NEXT WARNINGS AT 291500Z AND 300300Z. REFER TO
TROPICAL CYCLONE 08S (DIAMONDRA) WARNINGS (WTXS31 PGTW) FOR TWELVE-

REMARKS:
291500Z POSITION NEAR 16.6S 67.1E.
TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 637 NM
SOUTH-SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 10 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS DEEPENED CENTRAL CONVECTION SURROUNDING A
5 NM EYE. A 291022Z SSMI MICROWAVE IMAGE REVEALS TIGHTLY-CURVED
BANDING WRAPPING INTO A WELL-DEFINED MICROWAVE EYE. THE CURRENT
POSITION IS BASED ON THE EYE FEATURE WITH HIGH CONFIDENCE. THE
INITIAL INTENSITY HAS INCREASED TO 115 KNOTS BASED ON MATCHING
DVORAK INTENSITY ESTIMATES FROM PGTW, KNES AND FMEE. UPPER-LEVEL
ANALYSIS INDICATES TC 09S IS LOCATED IN A FAVORABLE ENVIRONMENT WITH
LOW VERTICAL WIND SHEAR (VWS) AND DUAL OUTFLOW CHANNELS. THE
FAVORABLE CONDITIONS SUPPORT THE SIGNIFICANT INTENSITY INCREASE (25
KNOTS) OVER THE PAST 12 HOURS. TC EUNICE IS SLOWLY TRACKING ALONG A
NEAR EQUATORIAL RIDGE (NER) TO THE NORTHEAST. TC 09S WILL CONTINUE
TO TRACK SOUTH-SOUTHEASTWARD OVER THE NEXT 24 HOURS AND IS EXPECTED
TO SHIFT EAST-SOUTHEASTWARD AS THE NER MODIFIES AND BECOMES MORE
WEST-TO-EAST ORIENTED. FAVORABLE CONDITIONS ARE EXPECTED TO PERSIST
ALLOWING FURTHER INTENSIFICATION LEADING TO A PEAK INTENSITY OF 140
KNOTS. AFTER TAU 36, THE COMBINED EFFECT OF INCREASING VWS AND
MARGINAL SEA SURFACE TEMPERATURES WILL INDUCE A SLOW WEAKENING
PROCESS THROUGH THE REMAINDER OF THE FORECAST PERIOD. AVAILABLE

REMARKS:
300300Z POSITION NEAR 18.0S 68.0E.
TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 608 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS DEEP SYMMETRIC CENTRAL CONVECTION
SURROUNDING A WELL-DEFINED 31NM EYE. A 292311Z GMI 89GHZ IMAGE
REVEALS DEEP CONVECTIVE BANDING WRAPPING INTO THE WESTERN QUADRANT
OF THE WELL DEFINED CENTRAL CORE. THE CURRENT POSITION IS BASED ON
THE AFOREMENTIONED EYE FEATURE WITH HIGH CONFIDENCE. THE INITIAL
INTENSITY IS BASED ON CONCURRING DVORAK INTENSITY ESTIMATES OF 140
KNOTS FROM PGTW AND KNES AS WELL AS THE SHARP CONSOLIDATED NATURE OF
THE CYCLONE. TC EUNICE IS LOCATED IN A FAVORABLE UPPER LEVEL
ENVIRONMENT DIRECTLY BELOW A POINT SOURCE PROVIDING RADIAL OUTFLOW
AND LOW (10 TO 20 KNOTS) VERTICAL WIND SHEAR (VWS). IN ADDITION, TC
09S IS TRACKING PARALLEL TO THE SEA SURFACE TEMPERATURE (SST)
GRADIENT PROLONGING ITS EXPOSURE TO SSTS GREATER THAN 26C. THESE
CONDITIONS ARE EXPECTED TO PERSIST, ENABLING TC EUNICE TO CONTINUE
INTENSIFYING THROUGH TAU 24 TO A MAXIMUM INTENSITY OF 150 KNOTS.
BEYOND TAU 24 TC 09S WILL STEADILY WEAKEN AS IT BEGINS TO ENCOUNTER
INCREASED VWS ASSOCIATED WITH A MID-LATITUDE TROUGH TO THE SOUTH AND
REDUCED OCEAN HEAT CONTENT. THE SYSTEM IS CURRENTLY TRACKING ALONG
THE SOUTHWESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) TO THE
NORTHEAST. THE SYSTEM WILL CONTINUE TO TRACK TO THE SOUTH-SOUTHEAST
BEFORE TURNING TOWARDS THE EAST AS THE NER REORIENTS TO THE NORTH.
BY THE END OF THE FORECAST PERIOD TC 09S WILL TRACK SOUTHEASTWARD AS
IT BECOMES ENTRAINED IN THE MID-LATITUDE WESTERLIES AND BEGINS EXTRA-
TROPICAL TRANSITION (ETT) BY TAU 96. THE SYSTEM IS FORECAST TO
COMPLETE ETT BY TAU 120. AVAILABLE DYNAMIC MODEL GUIDANCE CONTINUES
TO BE IN EXCELLENT AGREEMENT LEADING TO HIGH CONFIDENCE IN THE JTWC
FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 300000Z IS 38 FEET. NEXT

REMARKS:
301500Z POSITION NEAR 19.5S 68.9E.
TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 763 NM
SOUTH-SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS DEEP SYMMETRIC CENTRAL CONVECTION
SURROUNDING A SMALL 6 NM EYE. A SERIES OF MICROWAVE IMAGERY
INCLUDING A 301221Z SSMIS IMAGE REVEALS A PROBABLE EYEWALL
REPLACEMENT CYCLE TAKING PLACE. THE CURRENT POSITION IS BASED ON THE
EYE FEATURE WITH HIGH CONFIDENCE. THE INITIAL INTENSITY REMAINS AT
140 KNOTS BASED ON CONSISTENT DVORAK CURRENT INTENSITY ESTIMATES
FROM ALL REPORTING AGENCIES. UPPER-LEVEL ANALYSIS INDICATES TC 09S
IS LOCATED IN A FAVORABLE ENVIRONMENT WITH LOW TO MODERATE (10 TO 20
KNOTS) VERTICAL WIND SHEAR (VWS) AND RADIAL OUTFLOW AS EVIDENT ON
THE WATER VAPOR IMAGERY. THE CYCLONE IS CURRENTLY TRACKING ALONG THE
SOUTHWESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) TO THE
NORTHEAST. TC 09S WILL CONTINUE TO TRACK SOUTHEASTWARD OVER THE NEXT
12 HOURS BEFORE SLIGHTLY TURNING TOWARDS EAST-SOUTHEASTWARD AS THE
NER REORIENTS TO THE NORTH. FAVORABLE CONDITIONS ARE EXPECTED TO
PERSIST IN THE SHORT TERM ALLOWING THE SYSTEM TO MAINTAIN ITS
CURRENT INTENSITY THROUGH TAU. AFTERWARDS, THE CYCLONE IS EXPECTED
TO STEADILY WEAKEN AS IT BEGINS TO TRACK INTO AN UNFAVORABLE
ENVIRONMENT OF COOLER SEA SURFACE TEMPERATURES, INCREASING VWS AND
LOWER OCEAN HEAT CONTENT. BY TAU 72, TC 09S IS FORECAST TO INTERACT
WITH THE MID-LATITUDE WESTERLIES AND BEGIN EXTRA-TROPICAL
TRANSITION (ETT). TC EUNICE IS EXPECTED TO COMPLETE ETT BY THE END
OF THE FORECAST PERIOD OR POSSIBLY SOONER. AVAILABLE DYNAMIC MODEL
GUIDANCE REMAINS IN TIGHT GROUPING LENDING TO HIGH CONFIDENCE IN THE
JTWC TRACK FORECAST WHICH IS POSITIONED CLOSE TO MULTI-MODEL
CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 301200Z IS 38 FEET.

310300Z POSITION NEAR 20.3S 70.4E.
TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 710 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
AN OVERALL WEAKENING TREND WITH WARMING CONVECTIVE CLOUD TOPS AND AN
EXPANDING 17-NM EYE. A 302335Z SSMIS 91 GHZ IMAGE REVEALS FRAGMENTED
DEEP CONVECTIVE BANDING WRAPPING INTO THE LOW-LEVEL CIRCULATION
CENTER (LLCC), HOWEVER, DEEP CONVECTION OVER THE EASTERN SEMI-CIRCLE
HAS ERODED SIGNIFICANTLY. DESPITE LOW TO MODERATE NORTHEASTERLY
VERTICAL WIND SHEAR (VWS), THE POLEWARD OUTFLOW CHANNEL REMAINS
ROBUST DUE TO THE NORTHWESTERLY SUBTROPICAL JET POSITIONED TO THE
SOUTH. TC 09S IS TRACKING ALONG THE SOUTHERN PERIPHERY OF THE DEPP-
LAYERED STEERING RIDGE AND IS EXPECTED TO CONTINUE TRACKING EAST-
SOUTHEASTWARD THROUGH TAU 48. AFTER TAU 48, TC 09S SHOULD TURN
SOUTHEASTWARD AS IT ACCELERATES BETWEEN THE SUBTROPICAL RIDGE AND A
DEEP SHORTWAVE TROUGH. THE SYSTEM IS EXPECTED TO WEAKEN RAPIDLY
AFTER TAU 36 AS IT ENCOUNTERS INCREASING VWS AND COOLER SST (LESS
THAN 25C). AFTER TAU 48, FURTHER WEAKENING WILL OCCUR AS THE SYSTEM
BEGINS EXTRA-TROPICAL TRANSITION (ETT). TC 09S WILL COMPLETE ETT BY
TAU 72 AS IT BECOMES EMBEDDED IN THE SUBTROPICAL TROUGH AND GAINS
WEAK FRONTAL CHARACTERISTICS. DYNAMIC MODEL GUIDANCE REMAINS IN GOOD

REMARKS:
011500Z POSITION NEAR 22.0S 81.4E.
TROPICAL CYCLONE 09S (EUNICE), LOCATED APPROXIMATELY 986 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED EAST-SOUTHEASTWARD
AT 21 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY INDICATES A SLIGHT WEAKENING OF THE SYSTEM AS BOTH
EASTERN AND WESTERN SIDES HAVE BEGUN TO SLOWLY ERODE. HOWEVER, TC
09S STILL REMAINS WELL-ORGANIZED WITH TIGHTLY-CURVED BANDING
WRAPPING INTO A WELL-DEFINED CENTER. A 011154Z SSMIS IMAGE CLEARLY
DEPICTS AN EYE-LIKE FEATURE AND DECENT WRAPPING, WITH THE MAJORITY
OF THE DEEP CONVECTION LOCATED IN THE SOUTHWESTERN QUADRANT. UPPER
LEVEL ANALYSIS CONCLUDES THAT THE SYSTEM REMAINS IN MARGINAL
CONDITIONS, WITH MODERATE VERTICAL WIND SHEAR (VWS) OFFSET BY GOOD
POLEWARD OUTFLOW. THE CURRENT INTENSITY IS ASSESSED AT 80 KNOTS
BASED ON THE SLIGHTLY WEAKENING OF THE SYSTEM AND AN OVERALL
ANALYSIS OF DVORAK CURRENT INTENSITY ESTIMATES FROM ALL AGENCIES. TC
EUNICE IS TRACKING ALONG THE SOUTHERN PERIPHERY OF THE DEEP NEAR
EQUATORIAL RIDGE AND IS EXPECTED TO CONTINUE TRACKING EAST-
SOUTHEASTWARD OVER THE NEXT 12 HOURS. BEYOND THIS, TC 09S WILL START
TO TURN SOUTHEASTWARD AS IT TRACKS BETWEEN THE SUBTROPICAL RIDGE TO
THE EAST AND AN APPROACHING DEEP SHORTWAVE TROUGH. THE SYSTEM IS
EXPECTED TO WEAKEN RAPIDLY AT THIS POINT AS IT ENCOUNTERS INCREASING
VWS AND COOLER SST (LESS THAN 25C) AND WILL BEGIN EXTRA-TROPICAL
TRANSITION (ETT). TC EUNICE WILL COMPLETE ETT BY TAU 48 AS IT
BECOMES COMPLETELY EMBEDDED IN THE SUBTROPICAL TROUGH. DYNAMIC MODEL
GUIDANCE IS IN VERY GOOD AGREEMENT AND AS SUCH, THERE IS HIGH
CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 011200Z IS 30 FEET. NEXT WARNINGS AT 020300Z AND 021500Z.//

TROPICAL CYCLONE (TC) 09S (EUNICE), LOCATED APPROXIMATELY 945 NM
SOUTHWEST OF COCOS ISLAND, HAS TRACKED EAST-SOUTHEASTWARD AT 29
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY INDICATES A RAPIDLY WEAKENING SYSTEM WITH ERODING DEEP
CONVECTION PERSISTING OVER THE CENTER. A 02/0005Z SSMIS 37 GHZ IMAGE
DEPICTS CURVED BANDING WRAPPING INTO A WELL-DEFINED CENTER,
THEREFORE, THERE IS GOOD CONFIDENCE IN THE CURRENT POSITION. THE
CURRENT INTENSITY IS ASSESSED AT 65 KNOTS BASED ON DVORAK CURRENT
INTENSITY ESTIMATES RANGING FROM 65 TO 77 KNOTS (4.0 TO 4.5). TC 09S
IS TRACKING ALONG THE SOUTHERN PERIPHERY OF THE DEEP-LAYERED
STEERING RIDGE AND IS EXPECTED TO TURN SOUTHEASTWARD THROUGH TAU 36
AS IT ACCELERATES BETWEEN THE SUBTROPICAL RIDGE AND A DEEP SHORTWAVE
TROUGH. THE SYSTEM IS EXPECTED TO WEAKEN RAPIDLY AS IT ENCOUNTERS
INCREASING VERTICAL WIND SHEAR AND COOLER SST (LESS THAN 25C).
FURTHER WEAKENING WILL OCCUR AS THE SYSTEM BEGINS EXTRA-TROPICAL
TRANSITION (ETT). TC 09S WILL COMPLETE ETT BY TAU 36 AS IT BECOMES
EMBEDDED IN THE SUBTROPICAL TROUGH AND GAINS WEAK FRONTAL
CHARACTERISTICS. DYNAMIC MODEL GUIDANCE REMAINS IN GOOD AGREEMENT,
THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 020000Z IS 27 FEET. NEXT WARNINGS

REMARKS:
021500Z POSITION NEAR 30.4S 92.5E.
TROPICAL CYCLONE 09S (EUNICE), LOCATED APPROXIMATELY 1278 NM WEST-
SOUTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 40
KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON
021200Z MULTISPECTRAL SATELLITE IMAGERY AND A CORRESPONDING PGTW
SATELLITE FIX. THE INTENSITY OF 55 KNOTS IS CONSISTENT WITH A RECENT
DVORAK CURRENT INTENSITY ESTIMATE FROM PGTW. TC 09S IS ACCELERATING
RAPIDLY SOUTHEASTWARD IN THE GRADIENT BETWEEN A SUBTROPICAL RIDGE TO
THE NORTHEAST AND A MIDLATITUDE TROUGH TO THE SOUTHWEST. THE SYSTEM
IS ENCOUNTERING INCREASING VERTICAL WIND SHEAR AND COOLER SEA
SURFACE TEMPERATURES AS IT RAPIDLY APPROACHES A BAROCLINIC ZONE.
SATELLITE DATA, INCLUDING AMSU-DERIVED CORE TEMPERATURE ESTIMATES,
INDICATE THAT TC 09S IS WELL INTO THE EXTRATROPICAL TRANSITION
PROCESS. THE CYCLONE WILL COMPLETE THIS TRANSITION WITHIN THE NEXT
FEW HOURS, AND IS EXPECTED TO WEAKEN SLIGHTLY AS THE NEGATIVE
INFLUENCES OF PERISTENT VERTICAL WIND SHEAR AND PASSAGE OVER COOLER
WATER PERSIST. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT
TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED
FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
021200Z IS 20 FEET.//
