2.C ADDITIONAL INFORMATION:
T=5.0 CI=5.5-

DURING THE LAST 6 HOURS, THE HABANA EYE PATTERN HAS CONTINUED TO
DEGRADE TO EVOLVE INTO A CDO PATTERN. THE CLOUD TOPS HOWEVER CONTINUE
TO REMAIN VERY COLD IN THE NORTHERN SECTOR OF CDO WHILE THE MICROWAVE
TRANSMITTED DATA FROM 1331UTC SHOWED THAT THE LOW-LEVEL CIRCULATION
WAS STILL QUITE SYMMETRICAL. BY INERTIA AND KEEPING A DVORAK ANALYSIS
OF 5.5-, WE CAN STILL ESTIMATE WINDS OF ABOUT 85KT, LEAVING HABANA AT
THE THRESHOLD OF A TROPICAL CYCLONE.

AS FAR AS THE TRACK FORECAST IS CONCERNED, NO CHANGE. HABANA HAS
STARTED ITS TURN TO THE SOUTH-EAST AND WILL CONTINUE A SOUTHWARD
TRACK DURING THE NEXT 12 HOURS BY SLOWING DOWN. UNDER THE GROWING
INFLUENCE OF THE SUBTROPICAL RIDGE TO THE SOUTHEAST OF THE CYCLONE,
THE TRACK WILL TAKE A GENERAL WESTERLY DIRECTION BY THE END OF THE
DAY ON MONDAY. THERE IS STILL A STRONG DISPERSION OF AVAILABLE MODELS
ON THE EXACT TIMING AND LOCATION OF THE TURN WESTWARD AND AT A LONGER
RANGE. THE RSMC HAS OPTED FOR A SOUTHWARD TURN AT FRIDAY.

THE NORTHERN SHEAR SHOULD START TO WEAKEN SOON WHICH COULD HELP
HABANA TO INTENSIFY AGAIN FROM TUESDAY, ONCE HIS WESTWARD MOVEMENT
HAS STARTED. A PERSISTENT SLOWER DISPLACEMENT COULD AGAIN LIMIT THE
INTENSITY OF THE SYSTEM DUE TO THE LACK OF OCEANIC POTENTIAL. IN THIS
CONTEXT, REINFORCED BY THE POTENTIAL OCCURRENCE OF AN EYE WALL
REPLACEMENT CYCLE AND THE SMALL SIZE OF THE PHENOMENON, THE INTENSITY
FORECAST IS PARTICULARLY UNCERTAIN. ACCORDING TO THE SCENARIO OF NO
MAJOR CONSTRAINTS, THE RSMC OPTS FOR A PRESERVED INTENSIFICATION
POTENTIAL. HABANA IS EXPECTED TO INTENSIFY AGAIN AT THE THRESHOLD OF
AN INTENSE TROPICAL CYCLONE BEFORE WEAKENING MORE MARKEDLY FROM
THURSDAY ONWARDS UNDER THE EFFECT OF THE RISING WESTERLY SHEAR AT THE
FRONT OF A TROUGH.

DURING THE NEXT 5 DAYS, HABANA DO NOT THREATEN ANY INHABITED ISLAND.=

REMARKS:
072100Z POSITION NEAR 17.6S 80.4E.
07MAR21. TROPICAL CYCLONE 24S (HABANA), LOCATED APPROXIMATELY 772
NM SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHEASTWARD AT 04
KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS SITUATED NEAR
A LOW-LEVEL CENTER FEATURE EVIDENT IN A 071637Z METOP-C ASCAT PASS.
THE INTENSITY OF 100 KNOTS IS CONSISTENT WITH AN AVERAGE OF RECENT
SUBJECTIVE DVORAK AND AUTOMATED SATELLITE INTENSITY CONSENSUS
VALUES. TC 24S HAS WEAKENED STEADILY OVER THE PAST TWELVE HOURS, AND
TEMPORARILY LOST ITS EYE, UNDER THE INFLUENCE OF A SHORT-TERM
INCREASE IN VERTICAL WIND SHEAR AND COOLING OCEAN WATER BENEATH THE
SLOW-MOVING SYSTEM. TC 24S IS TURNING POLEWARD UNDER THE INFLUENCE
OF A SHIFTING STEERING PATTERN, WITH SUBTROPICAL RIDGING BUILDING TO
THE EAST. VERTICAL WIND HAS EASED A BIT OVER THE PAST SIX HOURS (10-
15 KTS), SEA SURFACE TEMPERATURES ARE MODERATELY FAVORABLE (26-28C)
AND STRONG POLEWARD OUTFLOW IS EVIDENT IN SATELLITE-DERIVED, UPPER-
LEVEL WIND VECTOR DATA. TC 24S IS EXPECTED TO TURN WESTWARD OVER THE
NEXT 24 TO 36 HOURS AS SUBTROPICAL RIDGING BUILDS TO THE SOUTH AND
TAKES OVER AS THE DOMINANT STEERING MECHANISM. THE SYSTEM WILL
CONTINUE FOLLOWING THE FLOW ASSOCIATED WITH THIS RIDGE, TURNING
POLEWARD BY TAU 120. FURTHER NEAR-TERM WEAKENING IS EXPECTED BEFORE
PASSAGE OVER WARM WATER, ROBUST OUTFLOW AND LOW VERTICAL WIND SHEAR
DRIVE A DISTINCT INTENSIFICATION TREND WITH POSSIBLE RAPID
INTENSIFICATION AFTER TAU 36. WITH THE EXCEPTION OF THE NAVGEM
TRACK, WHICH LIES SLIGHTLY TO THE SOUTH OF THE ENVELOPE, AND THE
ECMWF ENSEMBLE MEAN, WHICH LIES SLIGHTLY TO THE NORTH OF THE MODEL
ENVELOPE, NUMERICAL MODEL GUIDANCE IS IN VERY GOOD AGREEMENT,
LENDING HIGH CONFIDENCE TO THE CURRENT JTWC FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071800Z IS 36 FEET. NEXT WARNINGS AT
080900Z AND 082100Z. REFER TO TROPICAL CYCLONE 25S (IMAN) WARNINGS
(WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
082100Z POSITION NEAR 18.7S 80.5E.
08MAR21. TROPICAL CYCLONE 24S (HABANA), LOCATED APPROXIMATELY 848
NM SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT
04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY INDICATES THAT THE INNER CORE HAS DEGRADED DURING
THE PAST 12 HOURS, WITH A SHRINKING CIRRUS CANOPY AND NO EYE EVIDENT
IN THE LATEST SSMIS MICROWAVE PASS FROM 081319Z. THE CURRENT
WEAKENING TREND IS LIKELY PRIMARILY DUE TO OCEANIC COOLING BENEATH
THE CIRCULATION AS A RESULT OF ITS SLOW FORWARD MOTION. THE INITIAL
POSITION IS BASED ON A SATELLITE FIX FROM METEOSAT-8 WITH MODERATE
CONFIDENCE. THE INITIAL INTENSITY OF 65 KT IS ASSESSED WITH MODERATE
CONFIDENCE BASED ON A BLEND OF DVORAK ESTIMATES OF T4.0 FROM PGTW
AND FMEE, AN OBJECTIVE DVORAK ESTIMATE OF T3.4, AND A SATCON
ESTIMATE OF 69 KT. THE CYCLONE IS NOW BEGINNING ITS TURN TOWARD THE
WEST AS A WEAK SUBTROPICAL RIDGE (STR) BUILDS IN TO THE SOUTH. THIS
IS EXPECTED TO RESULT IN A GENERALLY WESTWARD TRACK THROUGH 72
HOURS. AFTER THIS TIME, A MID-LATITUDE SHORTWAVE TROUGH CURRENTLY
LOCATED SOUTHEAST OF MADAGASCAR IS EXPECTED TO ERODE THE RIDGE SOUTH
OF THE CYCLONE AND RESULT IN A SLOW POLEWARD TURN TOWARD THE SOUTH.
THE TRACK HAS BEEN NUDGED NORTH OF THE PREVIOUS FORECAST THROUGH 72
HOURS, IN BEST AGREEMENT WITH THE MULTI-MODEL CONSENSUS AND ECMWF
ENSEMBLE MEAN, WHICH NOW DEPICTS A SLIGHTLY STRONGER STR SOUTH OF
THE CYCLONE. THE TRACK AT 96-120 HOURS IS SLIGHTLY SLOWER, CLOSE TO
THE MULTI-MODEL CONSENSUS. FORECAST CONFIDENCE IS MODERATE GIVEN
RELATIVELY WEAK STEERING INFLUENCES DURING THE FORECAST PERIOD. THIS
TRACK BRINGS 24S OVER A WARM OCEANIC EDDY TO THE WEST WITH A
SLIGHTLY ACCELERATED SPEED DURING THE FIRST 72 HOURS, WHICH IN
COMBINATION WITH LOW VERTICAL SHEAR, SHOULD RESULT IN
REINTENSIFICATION. GIVEN THE CURRENTLY COMPACT VORTEX STRUCTURE,
THIS INTENSIFICATION COULD BE SWIFT, AND THE CYCLONE IS FORECAST TO
REACH A PEAK INTENSITY OF 115 KT BY 72 HOURS, WHICH IS ABOVE THE
MULTI-MODEL CONSENSUS, IN BEST AGREEMENT WITH HWRF AND COAMPS-TC.
AFTER 96 HOURS, THE APPROACHING MID-LATITUDE TROUGH IS EXPECTED TO
IMPART INCREASING VERTICAL SHEAR, AND THE SOUTHWARD TRACK AT THAT
TIME WILL BEGIN TAKING THE CYCLONE OVER SLIGHTLY COOLER WATERS,
RESULTING IN GRADUAL WEAKENING. CONFIDENCE IN THE INTENSITY FORECAST
IS MODERATE, GIVEN THE SUSCEPTIBILITY OF COMPACT STORMS TO QUICK
INTENSITY CHANGES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081800Z IS 24
FEET. NEXT WARNINGS AT 090900Z AND 092100Z.//

2.C ADDITIONAL INFORMATION:
T=4.0 CI=4.5-

OVER THE PAST 6 HOURS, HABANA'S PATTERN HAD A MIXED EVOLUTION. AFTER
GETTING WARMER TOPS AND LOOSING ITS SMALL EYE, DEEP CONVECTION BURSTS
AGAIN NEAR THE CENTER. 1318Z SSMIS MICROWAVE DATA STILL SHOW THE
EFFECT OF THE NORTH-EASTERLY SHEAR ON THE INNER CORE. HOWEVER ITS
RESOLUTION MAY NOT BE SUFFICIENT TO DISTINGUISH THE SMALL EYE.
FINALLY SMAP AND SMOS AFTERNOON SWATHS SHOW RESPECTIVELY 64 AND 59KT.
THIS SUGGEST THAT HURRICANE FORCE WINDS ARE STILL PRESENT IN HABANA
CIRCULATION.

HABANA IS STARTING TO ACCELERATE WESTWARD, UNDER THE STEERING
INFLUENCE OF THE SUBTROPICAL RIDGE TO ITS SOUTHEAST. TOMORROW, A NEW
RIDGE SETTLING TO THE SOUTHWEST OF THE SYSTEM SHOULD INFLECT THE
TRACK WEST-NORTHWESTWARD. COMPARED TO THE PREVIOUS FORECASTS, THE
LAST AVAILABLE GUIDANCES REINFORCED AGAIN THE NORTHWARD SHIFT WHICH
HAS BEEN TAKEN INTO ACCOUNT. FROM THURSDAY, MOST MODELS SUGGEST A
SOUTHWESTWARD, THEN SOUTHWARD OR EVEN SOUTHEASTWARD DIVE FROM
FRIDAY/SATURDAY. HOWEVER THERE IS STILL A STRONG SPREAD AMONG THE
GUIDANCE ON THIS NEW TURN. THE RSMC'S FORECAST IS BASED ON A
COMPROMISE BETWEEN THE BEST AVAILABLE GUIDANCE.

IN TERMS OF INTENSITY, AFTER THE WEAKENING TREND OBSERVED THIS
MONDAY, THE WESTWARD ACCELERATION OF THE SYSTEM IN THE DIRECTION OF
THE WIND SHEAR (WHICH REMAINS WEAK) SHOULD FREE IT FROM OTHER DRY AIR
INTRUSIONS. IT WILL THEN BENEFIT FROM GOOD UPPER DIVERGENCE AND
FAVORABLE OCEANIC POTENTIAL. INTENSIFICATION SHOULD THUS RESUME AS
FROM TUESDAY AND UNTIL THURSDAY OR FRIDAY. AT THE VERY END OF THE
FORECAST PERIOD, A POSSIBLE INCREASE IN WEST-NORTHWESTERLY WIND SHEAR
AHEAD OF A TROUGH COULD WEAKEN HABANA.
OVER THE NEXT 5 DAYS, HABANA DOES NOT POSE ANY THREAT TO INHABITED
LANDS.=

REMARKS:
092100Z POSITION NEAR 17.8S 77.7E.
09MAR21. TROPICAL CYCLONE 24S (HABANA), LOCATED APPROXIMATELY 726
NM SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-NORTHWESTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. TC 24S SHOWED SIGNIFICANT
DEVELOPMENT OVER THE PAST TWELVE HOURS AS IT MOVED AWAY FROM A COLD
POOL AND INTO WARMER WATERS. A 10NM EYE BEGAN SHOWING OVER
THE LAST THREE HOURS PRIOR THE 091800Z FIX. A MICROWAVE EYE IN A
091750Z GPMI SERIES LENDS EXCELLENT CONFIDENCE TO THE INITIAL
POSITION. CONFIDENCE IN THE CURRENT INTENSITY IS NOT QUITE AS HIGH,
BUT STILL GOOD: THE PGTW DVORAK ESTIMATE CLIMBED TO T5.0 (90 KTS)
AND RAW ADT ESTIMATES JUMPED TO T5.6. ENVIRONMENTAL CONDITIONS HAVE
IMPROVED AND LOOK TO REMAIN FAVORABLE FOR THE NEXT 48 HOURS.
VERTICAL WIND SHEAR IS BELOW 15 KNOTS, SSTS ARE  ABOVE 29C ALONG
TRACK, AND ANIMATED WATER VAPOR IMAGERY SHOWS RADIAL OUTFLOW OVER A
RELATIVELY SMALL AND TIGHTLY WRAPPED SYSTEM. THE SYSTEM IS COCOONED
FROM THE SHEAR ZONE ON THE POLEWARD SIDE, WHILE TOTAL PRECIPITABLE
WATER LOOPS SHOW THE CORE OF THE SYSTEM IS WELL SATURATED WITH DEEP
MOISTURE. SEA SURFACE TEMPERATURE, NOT VERTICAL WIND SHEAR, HAS BEEN
THE PRIMARY INFLUENCE ON INTENSITY ON THIS STORM. THE SUBTROPICAL
RIDGE TO THE SOUTHEAST IS PROVIDING THE STEERING FORCE AND HAS
NUDGED THE LLCC SLIGHTLY EQUATORWARD, WHICH IS CONSISTENT WITH
CURRENT AND PREVIOUS GUIDANCE. THERE IS GOOD CONFIDENCE IN THE
TRACK. THE RIDGE WILL CONTINUE DRIVING THE SYSTEM WEST-NORTHWESTWARD
THROUGH THE NEXT 36 HOURS, WHEN A DEEPENING SHORT WAVE TROUGH
ASSOCIATED WITH THE MID-LATITUDE WESTERLIES WEAKENS THE RIDGE. AFTER
TAU 36, THE SYSTEM WILL LOSE STEERING INFLUENCE FROM THE RIDGE AND
BEGIN A SLOW, GRACEFUL BEND INTO THE MID-LATITUDES, PEAKING IN
INTENSITY NEAR TAU 48. ALTHOUGH MODEL GUIDANCE SPREADS AS TC 24S
TURNS POLEWARD, IT STILL REMAINS IN EXCELLENT AGREEMENT ON THE
OVERALL SCENARIO. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z IS 30
FEET. NEXT WARNINGS AT 100900Z AND 102100Z.//
