IN SUCH A CONFIGURATION, OBJECTIVE ANALYSES SEEM A LITTLE LOW, AND THE REUNION RSMC OPTS FOR A SLIGHTLY LOWER T OF 3.5, ALTHOUGH THE ASCAT PASS OF 1713UTC LEAVES MAXIMUM VALUES OF 40KT. CANDICE'S MAXIMUM WINDS ARE THEN ESTIMATED AT 45KT AT 18UTC, LEAVING THE SYSTEM STILL IN THE MODERATE TROPICAL STORM STAGE. THE MARKED ACCELERATION OVER THE LAST FEW HOURS HAS SLIGHTLY ALTERED THE TRACK, WITH THE SYSTEM MOVING FURTHER SOUTH-SOUTHEAST UNTIL FRIDAY MORNING AS A RIDGE OF HIGH PRESSURE STRENGTHENS TO THE EAST AND A TROUGH ARRIVES TO THE SOUTHWEST. BETWEEN FRIDAY AND SATURDAY, THE SYSTEM BEGINS A SOUTHWESTERLY TURN, WITH THE TEMPORARY WITHDRAWAL OF THE RIDGE TO THE EAST, WHICH GIVES RISE TO A NORTHEASTERLY FLOW ALOFT. FROM SUNDAY ONWARDS, AS THE SYSTEM WEAKENS, THE MAIN FLOWS RETURN TO LOWER LEVELS. THE SYSTEM RESUMES A SOUTH-EASTERLY DIRECTION ALONG THE SOUTH-WESTERN EDGE OF THE RIDGE TO THE EAST, WHICH SWELLS TO THE NORTH OF THE SYSTEM. IN TERMS OF INTENSITY, LITTLE CHANGE FROM THE PREVIOUS FORECAST. DESPITE CANDICE'S ARRIVAL OVER LESS ENERGETIC WATERS, THE SHORT WINDOW OF INTENSIFICATION SHOULD PERSIST UNTIL MID-DAY FRIDAY, THANKS TO A FAVORABLE ENVIRONMENT (LOW VERTICAL WIND SHEAR AND INCREASING UPPER LEVEL DIVERGENCE). CANDICE COULD THEN REACH THE STAGE OF A STRONG TROPICAL STORM ON FRIDAY MORNING. TOWARDS THE END OF THE WEEK, THE STRENGTHENING OF THE NORTH TO NORTH-WESTERLY SHEAR AND THE DEFINITIVE LOSS OF WARM TROPICAL WATERS SOUTH OF 25AOS SHOULD ENCOURAGE CANDICE TO EVOLVE INTO A POST-TROPICAL SYSTEM ON SATURDAY, THEN INTO AN EXTRATROPICAL DEPRESSION AS IT FILLS IN FROM SUNDAY. WITH CANDICE NOW FURTHER AWAY, THE IMPACT ON THE MASCAREIGNES IS REDUCED AND CANDICE NO LONGER POSES A RISK TO INHABITED LAND.=

NIL
2.C ADDITIONAL INFORMATION:
AFTER A PHASE OF CONVECTIVE ACTIVITY AROUND 00UTC, THE CONVECTION
AROUND CANDICE HAS WEAKEN OVER THE LAST 6 HOURS. A BAND OF DRY AIR
HAS GRADUALLY WRAPPED AROUND THE CENTER FROM THE WEST. THE ASCAT
PASS AT 0430Z SHOWS A GENERALLY ASYMMETRICAL STRUCTURE, WITH A GALE
EXTENDING FAR TO THE SOUTH AND RESTRICTED TO THE NORTH. MAXIMUM
WINDS ARE AROUND 45KT, WITH A FEW STORM-FORCE VALUES, BUT FAR FROM THE
CENTER. CANDICE REMAINS A MODERATE TROPICAL STORM WITH WINDS OF 45KT.
AS CANDICE BEGAN TO TURN SOUTH, IT SLOWED DOWN A LITTLE. NO REAL
CHANGE IN PHILOSOPHY ON THE OVERALL TRACK, BUT THIS SLOWDOWN
SLIGHTLY MODIFIES THE PREVIOUS TRACK FORECAST BY MOVING A LITTLE
FURTHER WEST. CANDICE'S MOVEMENT IS ESSENTIALLY DRIVEN BY A RIDGE OF
HIGH PRESSURE TO THE EAST OF THE SYSTEM. THIS WILL FORCE IT TO MOVE
SOUTHWARDS AND THEN SOUTH-SOUTH-WESTWARDS TODAY. FROM SUNDAY
ONWARDS, AS THE SYSTEM WEAKENS, THE DIRECTING FLOWS RESUME AT LOWER
LEVELS. THE SYSTEM RESUMES SOUTHEASTWARD MOVEMENT ALONG THE
SOUTHWESTERN EDGE OF THE RIDGE.
IN TERMS OF INTENSITY, LITTLE CHANGE FROM THE PREVIOUS FORECAST. THE
SHORT WINDOW OF INTENSIFICATION THANKS TO A FAVORABLE ENVIRONMENT
(LOW VERTICAL WIND SHEAR AND INCREASING UPPER LEVEL DIVERGENCE) SEEMS
TO BE COMING TO AN END, AND THE POSSIBILITY OF REACHING THE STRONG
TROPICAL STORM STAGE IS RECEDING. IN THE NEXT 24 HOURS, NORTH TO
NORTH-WEST SEGMENT SHEARING WILL STRENGTHEN, THE INTRUSION OF DRY AIR
INTO THE CENTER AND THE DEFINITIVE LOSS OF WARM TROPICAL WATERS SOUTH
OF 25°S SHOULD FAVOR THE DEVELOPMENT OF A POST-TROPICAL SYSTEM ON
SATURDAY, THEN AN EXTRATROPICAL DEPRESSION AS IT FILLS IN FROM SUNDAY.
NO IMPACT ON LAND.

THE BEST-TRACK HAS THEREFORE BEEN MODIFIED TO A SEVERE TROPICAL STORM WITH MAXIMUM WINDS OF 50KT IN THE SOUTH-WEST QUADRANT OF THE SYSTEM AT 00 AND 06Z. OVER THE PAST 6 HOURS, THERE HAS BEEN LITTLE CHANGE IN THE CLOUD STRUCTURE OF SEVERE TROPICAL STORM CANDICE. CONVECTIVE ACTIVITY IS LIMITED TO A PERIMETER VERY CLOSE TO THE CENTER, NOTABLY IN THE WESTERN SEMICIRCLE. THE RSMC THEREFORE MAINTAINS THE SYSTEM AS A SEVERE TROPICAL STORM WITH WINDS OF 50KT. IN TERMS OF TRACK, LITTLE HAS CHANGED FROM PREVIOUS FORECASTS. CANDICE'S MOVEMENT IS ESSENTIALLY DRIVEN BY A RIDGE OF HIGH PRESSURE TO THE EAST OF THE SYSTEM. THIS WILL FORCE IT TO MOVE SOUTHWARDS AND THEN SOUTH-SOUTH-WESTWARDS OVERNIGHT AND TOMORROW. FROM SUNDAY ONWARDS, AS THE SYSTEM WEAKENS, THE MAIN FLOWS RESUME AT LOWER LEVELS. THE SYSTEM RESUMES A SOUTH-EASTERLY MOVEMENT ALONG THE SOUTH-WESTERN EDGE OF THE RIDGE. IN TERMS OF INTENSITY, AFTER ITS SHORT PASSAGE TO THE STRONG TROPICAL STORM STAGE TODAY, CANDICE IS EXPERIENCING A STRENGTHENING OF THE NORTH TO NORTH-WESTERLY WIND SHEAR AND AN INTRUSION OF DRY AIR APPROACHING THE CENTER OF THE SYSTEM. IN ADDITION, THE ARRIVAL OF COLDER WATERS TO THE SOUTH MEANS THAT CANDICE WILL WEAKEN OVER THE NEXT 24 HOURS, THEN EVOLVE INTO AN EXTRATROPICAL DEPRESSION AS IT FILLS IN FROM SUNDAY ONWARDS.

TROPICAL CYCLONE 08S (CANDICE), LOCATED APPROXIMATELY 547 NM SOUTHEAST OF ST DENIS, HAS TRACKED SOUTHEASTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MINIMUM CENTRAL PRESSURE AT 261200Z IS 988 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 261200Z IS 20 FEET. NEXT WARNINGS AT 270300Z AND 271500Z. REFER TO TROPICAL CYCLONE 06S (ANGGREK) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES. // NNNN
WDXS31 PGTW 261500 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/PROGNOSTIC REASONING FOR TROPICAL CYCLONE 08S (CANDICE) WARNING NR 004// RMKS/ 1. FOR METEOROLOGISTS. 2. 6 HOUR SUMMARY AND ANALYSIS. SUMMARY: INITIAL POSITION: 26.8S 62.5E INITIAL INTENSITY: 45 KTS GEOGRAPHIC REFERENCE: 547 NM SOUTHEAST OF ST DENIS MOVEMENT PAST 6 HOURS: SOUTHEASTWARD AT 10 KTS SIGNIFICANT WAVE HEIGHT: 20 FEET SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION: ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS TROPICAL CYCLONE (TC) 08S (CANDICE) TRANSITING SOUTHEAST AT 10KTS. THE SYSTEM APPEARS TO BE TRANSITING ON THE NORTHWESTERN PERIPHERY OF A MID-LEVEL RIDGE TO THE SOUTHEAST THAT HAS BEGUN TO INFLUENCE THE STORM AS TC 08S HAS BECOME INCREASINGLY SHALLOW OVER THE LAST TWELVE HOURS. THE PRIMARY HINDRANCE FOR INTENSIFICATION IS LOW SEA SURFACE TEMPERATURES (SST) OF 24-25C, DESPITE FAVORABLE OUTFLOW ALOFT AND LOW LEVELS OF VERTICAL WIND SHEAR. DRY AIR ENTRAINMENT IS APPARENT IN THE CLEARER SKIES TO THE NORTH. THE INITIAL POSITION OF 26.8S 62.5E WAS ASSESSED WITH LOW CONFIDENCE BASED ON ANIMATED IMAGERY AND AN EWSG-2 262215Z PASS DEPICTING AN ASYMMETRICAL SYSTEM WITH A SWATH OF DEEP LAYERS OF CONVECTION IN THE SOUTHERN HEMISPHERE OF THE CYCLONE. THE INITIAL INTENSITY OF 45KTS WAS ASSESSED WITH LOW CONFIDENCE BASED ON PERSISTENCE AND AGENCY AND OBJECTIVE FIXES BELOW. INITIAL WIND RADII BASIS: PERSISTENCE CURRENT STEERING MECHANISM: THE NORTHWESTERN PERIPHERY OF A MID LEVEL RIDGE TO THE SOUTHEAST. AGENCY DVORAK AND AUTOMATED FIXES: PGTW: T3.5 - 55 KTS KNES: T3.0 - 45 KTS FMEE: T3.5 - 55 KTS CIMSS ADT: 45 KTS AT 261130Z FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: UNFAVORABLE VWS: 25-30 KTS SST: 25-26 CELSIUS OUTFLOW: STRONG POLEWARD ANALYSIS CONFIDENCE: INITIAL POSITION: LOW INITIAL INTENSITY: LOW INITIAL WIND RADII: LOW 3. FORECAST REASONING. SIGNIFICANT FORECAST CHANGES: THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST FROM THE PREVIOUS WARNING. FORECAST DISCUSSION: TC 08S IS FORECAST TO CONTINUE ON A SOUTHWESTWARD TRACK THROUGH THE END OF THE FORECAST PERIOD (TAU 36) AS IT CONTINUES DOWN THE WESTERN PERIPHERY OF THE MID-LEVEL RIDGE TO THE EAST. SST WILL CONTINUE TO BE UNFAVORABLE THROUGH THE END OF THE FORECAST PERIOD, REMAINING BELOW 25C. SIGNIFICANT WIND SHEAR (20-30KTS) AND DRY AIR ENTRAINMENT, WHICH WILL FULLY ENGULF THE SYSTEM IN THE SHORT-TERM, WILL CONTRIBUTE TO THE RAPID WEAKENING OF TC 08S, LEADING TO FULL DISSIPATION BY TAU 36. MODEL DISCUSSION: DETERMINISTIC MODEL GUIDANCE IS IN GOOD AGREEMENT THAT TC 08S WILL CONTINUE TO TRACK SOUTHWEST THROUGH THE REMAINDER OF THE FORECAST PERIOD. THE AGREEMENT IS FURTHER JUSTIFIED WITH A MINIMAL CROSS-TRACK DIFFERENTIAL OF 110NM BY TAU 36. MODEL GUIDANCE IS ALSO IN AGREEMENT THAT THE SYSTEM WILL RAPIDLY AND CONSISTENTLY WEAKEN TO DISSIPATION AT 30KTS BY TAU 36. FORECAST CONFIDENCE: TRACK 0 - 72 HR: HIGH INTENSITY 0 - 72 HR: HIGH// NNNN

IN FACT, THE METEOR HAS JUST BEEN DOWNGRADED TO A MODERATE TROPICAL STORM DUE TO INCREASINGLY HOSTILE ENVIRONMENTAL CONDITIONS, CAUSED BY DETRIMENTAL HIGH-LEVEL VERTICAL WIND SHEAR AND THE PRESENCE OF UNDERLYING FRESH WATER. THE CONVECTIVE ACTIVITY OBSERVED IN THE SOUTH-EAST QUADRANT DURING THE PREVIOUS NETWORK IS NOW NON-EXISTENT, AND THEREFORE NO LONGER ALLOWS FOR CLASSIC DVORAK ANALYSIS. IN THIS CONFIGURATION AND IN THE ABSENCE OF MICROWAVE DATA, PRECISE IDENTIFICATION OF THE LOW-LEVEL CENTER IS COMPLICATED. IN TERMS OF TRACK, LITTLE HAS CHANGED FROM PREVIOUS FORECASTS. CANDICE'S MOVEMENT IS ESSENTIALLY DRIVEN BY A RIDGE OF HIGH PRESSURE TO THE EAST OF THE SYSTEM. THIS WILL FORCE IT TO MOVE SOUTHWARDS AND THEN SOUTH-SOUTH-WESTWARDS OVERNIGHT AND TOMORROW. FROM SUNDAY ONWARDS, AS THE SYSTEM WEAKENS, THE MAIN FLOWS RESUME AT LOWER LEVELS. THE SYSTEM RESUMES A SOUTH-EASTERLY MOVEMENT ALONG THE SOUTH-WESTERN EDGE OF THE RIDGE. IN TERMS OF INTENSITY, CANDICE WILL CONTINUE TO EXPERIENCE STRENGTHENING NORTH TO NORTH-WESTERLY WIND SHEAR ALOFT, AS WELL AS AN INTRUSION OF DRY AIR APPROACHING THE CENTER OF THE SYSTEM. IN ADDITION, THE ARRIVAL OF COLDER WATERS TO THE SOUTH MEANS THAT CANDICE WILL WEAKEN OVER THE NEXT 24 HOURS, BEFORE BECOMING AN EXTRATROPICAL DEPRESSION AS IT FILLS IN FROM SUNDAY ONWARDS. NO IMPACT ON LAND.=

DEPRESSION
2.B LONGER-RANGE OUTLOOK:
NIL
2.C ADDITIONAL INFORMATION:
MODERATE TROPICAL STORM CANDICE IS CONTINUING ITS PHASE OF SUSTAINED
WEAKENING DUE TO INCREASINGLY HOSTILE ENVIRONMENTAL CONDITIONS, WITH
DETRIMENTAL HIGH-LEVEL SHEAR FOR ITS STRUCTURE, AND THE PRESENCE OF
UNDERLYING COOL WATERS. CONVECTIVE ACTIVITY IS INSIGNIFICANT. THE 2135Z
AMSR-2 PASS REVEALS A BROAD, EXPOSED LOW-LEVEL STRUCTURE, WITH
ASYMMETRICAL STRONG WINDS IN THE SYSTEM'S SOUTHERN SEMICIRCLE.
CANDICE SHOULD STABILIZE AS A TROPICAL STORM FOR A FEW MORE HOURS
BEFORE DEFINITIVELY LOSING ITS TROPICAL ATTRIBUTES.
IN TERMS OF TRACK, LITTLE CHANGE FROM PREVIOUS FORECASTS. CANDICE'S
MOVEMENT IS ESSENTIALLY DRIVEN BY A RIDGE OF HIGH PRESSURE TO THE EAST
OF THE SYSTEM. THIS WILL FORCE IT TO MOVE SOUTH-SOUTHEAST DURING THE
DAY. FROM SUNDAY ONWARDS, AS THE SYSTEM WEAKENED, THE STEERING FLOWS
RESUMED AT LOWER LEVELS. THE SYSTEM RESUMES SOUTHEASTWARD
MOVEMENT ALONG THE SOUTHWESTERN EDGE OF THE RIDGE.
IN TERMS OF INTENSITY, CANDICE WILL CONTINUE TO EXPERIENCE
STRENGTHENING NORTH TO NORTH-WESTERLY WINDSHEAR ALOFT, AS WELL AS
DRY AIR INTRUSION. IN ADDITION, THE PRESENCE OF COLDER WATERS IS HELPING
TO WEAKEN CANDICE OVER THE NEXT FEW HOURS, AS IT BEGINS ITS
EXTRATROPICALIZATION PHASE. ON SUNDAY, IT WILL EVOLVE INTO AN
EXTRATROPICAL DEPRESSION AS IT FILLS IN.
NO IMPACT ON LAND.
