WTXS21 PGTW 20150127 09:30z MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// 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.// ========================================================================= WTXS32 PGTW 20150127 21:00z MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/TROPICAL CYCLONE 09S (NINE) WARNING NR 001// RMKS/ 1.

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.

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.

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.

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.

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).

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.//
