ANGGREK WILL CONTINUE TO WEAKEN AND BEGIN ITS EXTRATROPICALIZATION PHASE IN THE VERY NEAR FUTURE, DRIVEN BY BAROCLINIC PROCESSES. HOWEVER, IT SHOULD MAINTAIN SIGNIFICANT INTENSITY, BECOMING A POWERFUL EXTRATROPICAL STORM OVER THE NEXT 24 HOURS, WITH WINDS REMAINING ABOVE STORM STRENGTH. ANGGREK DOES NOT THREAT INHABITED LANDS. THIS IS THE LAST BULLETIN FOR THIS SYSTEM, WHICH IS NEVERTHELESS CONTINUING TO EVOLVE IN TEMPERATE LATITUDES.

WDXS32 PGTW 302100 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/PROGNOSTIC REASONING FOR TROPICAL CYCLONE 06S (ANGGREK) WARNING NR 032// RMKS/ 1. FOR METEOROLOGISTS. 2. 6 HOUR SUMMARY AND ANALYSIS. SUMMARY: INITIAL POSITION: 30.6S 76.1E INITIAL INTENSITY: 90 KTS GEOGRAPHIC REFERENCE: 1196 NM SOUTHEAST OF PORT LOUIS, MAURITIUS MOVEMENT PAST 6 HOURS: EAST-SOUTHEASTWARD AT 15 KTS SIGNIFICANT WAVE HEIGHT: 43 FEET SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION: ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS THAT TROPICAL CYCLONE (TC) 06S (ANGGREK) IS CONTINUING TO GIVE WAY TO STRONG (40 KTS) NORTHWESTERLY VERTICAL WIND SHEAR (VWS). OVER THE LAST TWELVE HOURS, TC 06S LOW-LEVEL CIRCULATION (LLC) HAS BECOME DISLOCATED AND PARTIALLY EXPOSED NORTHWEST OF THE OUTFLOW SUPPORT ALOFT, AWAY FROM THE SOUTHWESTWARD PROGRESSION OF THE UPPER-LEVEL CONVECTIVE SUPPORT FEATURES. THE INITIAL POSITION IS ASSESSED WITH MEDIUM CONFIDENCE DUE TO CONTINUED FLARING CONVECTION JUST DOWNSTREAM OF THE LLC OBSCURING THE AFOREMENTIONED PARTIALLY EXPOSED EYE FEATURE AROUND THE TIGHTEST AREA OF CYCLONIC TURNING. THE INITIAL INTENSITY IS SET AT 90 KTS WITH MEDIUM CONFIDENCE. THE INTENSITY IS ASSESSED FROM A 301340Z SYNTHETIC APERTURE RADAR (SAR) IMAGE INDICATING SWATHS OF 90 KTS ALONG THE WESTERN AND EASTERN PERIPHERIES OF THE LLCC. THE INTENSITY ESTIMATE IS EVALUATED ABOVE THE MAJORITY OF THE OBJECTIVE AND SUBJECTIVE FIXES AS A DECREASE IN CONVECTIVE STRUCTURES HAS MOVED DVORAK ESTIMATES LOWER THAN OBSERVED FROM SAR AND ASCAT DATA THROUGHOUT THE LAST 12 HRS. INITIAL WIND RADII BASIS: SAR DATA CURRENT STEERING MECHANISM: SOUTHWESTERN PERIPHERY OF A DEEP-LAYER SUBTROPICAL RIDGE (STR) TO THE NORTHEAST. AGENCY DVORAK AND AUTOMATED FIXES: PGTW: T4.5 - 77 KTS DEMS: T4.5 - 77 KTS FIMP: T4.5 - 77 KTS CIMSS ADT: 59 KTS AT 301500Z FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: HIGHLY UNFAVORABLE VWS: 30+ KTS SST: 23-24 CELSIUS OUTFLOW: STRONG POLEWARD ANALYSIS CONFIDENCE: INITIAL POSITION: MEDIUM INITIAL INTENSITY: MEDIUM INITIAL WIND RADII: MEDIUM 3. FORECAST REASONING. SIGNIFICANT FORECAST CHANGES: THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST FROM THE PREVIOUS WARNING. FORECAST DISCUSSION: TC 06S IS FORECAST TO CONTINUE TRACKING SOUTHEASTWARD ALONG THE OUTER PERIPHERY OF THE SUBTROPICAL RIDGE TO THE NORTHEAST AND TRAILING EDGE OF A STRONG FRONTAL BOUNDARY TO THE SOUTH-SOUTHEAST. THE CYCLONE CONTINUES TO BE SHEARED APART BY 40 KTS OF NORTHWESTERLY SHEAR AND SUPPRESSED BY A DEEP LAYER OF DRY AIR FROM THE IMMEDIATE WEST. TC PHASE SPACE DIAGRAM GUIDANCE SHOWS TC 06S CURRENTLY TRANSITIONING INTO AN ASYMMETRIC WARM-CORE SYSTEM THROUGH THE EXTRA-TROPICAL TRANSITION, AND EXPECTED TO BECOME COMPLETELY EXTRA-TROPICAL BY TAU 24 AS THE SYSTEM BECOMES SUPER-IMPOSED UNDER A WESTERLY JET MAX AND INTO MUCH COOLER SEA SURFACE TEMPERATURES (20C) NEAR THE END OF THE FORECAST PERIOD. MODEL DISCUSSION: DETERMINISTIC MODEL GUIDANCE REMAINS IN VERY GOOD AGREEMENT ON A SOUTHEASTWARD TRACK THROUGH THE REMAINDER OF THE FORECAST PERIOD, WITH A CROSS-TRACK SPREAD OF JUST 70NM BY TAU 24. THE JTWC TRACK IS CONSISTENT WITH THE CONSENSUS MEAN AS TC 06S CONTINUES THROUGH ITS EXTRA-TROPICAL TRANSITION. INTENSITY GUIDANCE REMAINS IN MEDIUM AGREEMENT, WHILE A RAPID WEAKENING PHASE IS FORECAST INTO TAU 24, INTENSITY GUIDANCE VARIES MODERATELY PAST TAU 12; HOWEVER, THE JTWC FORECAST IS CONSISTENT WITH THE CONSENSUS, AND A CONTINUED RAPID DECREASE TO 50 KTS IS EXPECTED BY TAU 24.

TROPICAL CYCLONE 06S (ANGGREK), LOCATED APPROXIMATELY 1767 NM WEST-SOUTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED EAST- SOUTHEASTWARD AT 35 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A RAPIDLY DETERIORATING LOW LEVEL CIRCULATION CENTER (LLCC), WHICH IS BECOMING INCREASINGLY ELONGATED. THE CIRCULATION IS DEVOID OF ANY SIGNIFICANT CONVECTION AT THIS POINT, WHICH IS DRIVING SUBJECTIVE AND OBJECTIVE DVORAK-BASED INTENSITY ESTIMATES DOWN TO THE 35 KNOT RANGE. HOWEVER, A SERIES OF SAR AND ULTRA-HIGH RESOLUTION ASCAT PASSES OVER THE LAST COUPLE OF DAYS HAVE CONFIRMED THAT THE WIND FIELD REMAINS SIGNIFICANTLY STRONGER THAN THE SATELLITE ESTIMATES WOULD SUGGEST. SO, WHILE STILL WEAKENING, THE SYSTEM REMAINS A STRONG TYPHOON STRENGTH SYSTEM. PHASE SPACE DIAGRAMS AND JTWC PHASE ANALYSIS SHOWS THE SYSTEM IS ALREADY MAKING THE TRANSITION TO AN EXTRA-TROPICAL LOW PRESSURE SYSTEM AND IT IS EXPECTED TO COMPLETE THIS ETT PROCESS WITHIN THE NEXT 12 HOURS AS THE SYSTEM RACES SOUTHEASTWARD ALONG THE TIGHT GRADIENT BETWEEN A ROBUST UPPER-LEVEL TROUGH TO THE SOUTHWEST AND A STRONG STR TO THE NORTHEAST. 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. MINIMUM CENTRAL PRESSURE AT 310600Z IS 983 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 310600Z IS 40 FEET. REFER TO TROPICAL CYCLONE 09S (NINE) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. // NNNN
