Not sure why MFR has this at 60 knots when it has a cleared out eye.

Of course, neither JTWC, SAB, or MFR can't seem to be getting Dvorak right. Should be T5.5 without constraints,T5.0 with them.

REMARKS:
150900Z POSITION NEAR 17.8S 63.0E.
TROPICAL CYCLONE 06S (BERGUITTA), LOCATED APPROXIMATELY 362 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED NORTHWARD AT
01 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
MULTI-SPECTRAL SATELLITE IMAGERY (MSI) SHOWS INCREASINGLY WELL
ORGANIZED DEEP CONVECTION, WITH A 10 NM WIDE EYE FEATURE DEVELOPING
OVER THE NEARLY STATIONARY LOW LEVEL CIRCULATION CENTER (LLCC). THE
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE
FEATURE VISIBLE IN MULTI-SPECTRAL IMAGERY. A TIGHT HOOK FEATURE
OBSERVED IN THE 150525Z 89 GHZ METOP-B AMSU SSMIS. THE INITIAL
INTENSITY ASSESSMENT OF 75 KNOTS BASED ON MULTI-AGENCY DVORAK
CURRENT INTENSITY ESTIMATES RANGING FROM T4.5 TO T5.0 (77 TO 90
KNOTS), FROM PGTW AND KNES RESPECTIVELY. THE INITIAL INTENSITY IS
ALSO SUPPORTED BY A MULTI-PLATFORM SATELLITE WIND ANALYSIS ESTIMATE
OF 75 KNOTS. ENVIRONMENTAL ANALYSIS REVEALS THAT TC 06S REMAINS IN
AN AREA FAVORABLE FOR FURTHER INTENSIFICATION WITH LOW VERTICAL WIND
SHEAR (5 TO 10 KNOTS) AND WARM (28 CELSIUS) SEA SURFACE
TEMPERATURES. UPPER LEVEL ANALYSIS SHOWS THAT THEY SYSTEM HAS GOOD
EQUATORWARD AND POLEWARD OUTFLOW WITH THE POLEWARD OUTFLOW CHANNEL
TAPPING INTO THE MID-LATITUDE WESTERLIES. TC 06S IS FORECAST TO
REMAIN QUASI-STATIONARY OVER THE NEXT 36 HOURS DUE TO WEAK AND
COMPETING STEERING INFLUENCES OF A SUB-TROPICAL RIDGE (STR) TO THE
SOUTH, AND ANOTHER STR BUILDING OVER EASTERN MADAGASCAR. AFTER TAU
36, THE SYSTEM IS FORECAST TO ACCELERATE TO THE SOUTHWEST DUE TO A
WEAKNESS BEGINS TO DEVELOP BETWEEN THE TWO SUB-TROPICAL RIDGES.
AROUND TAU 48, THE STR LOCATED TO THE SOUTHEAST BEGINS TO BUILD AND
TAKES OVER AS THE PRIMARY STEERING FEATURE FOR THE DURATION OF THE
FORECAST. THE QUASI-STATIONARY (QS) MOTION AND FAVORABLE
ENVIRONMENTAL CONDITIONS ARE FORECAST TO ALLOW FOR A PERIOD OF RAPID
INTENSIFICATION THROUGH TAU 36 AND THE SYSTEM WILL EVENTUALLY REACH
A PEAK OF 105 KNOTS AROUND TAU 48. AFTER TAU 48, THE SYSTEM WILL
BEGIN TO GRADUALLY WEAKEN AS VWS INCREASES AND SEA SURFACE
TEMPERATURES DECREASE. AVAILABLE DYNAMIC MODEL GUIDANCE IS IN
GENERALLY GOOD AGREEMENT THAT THE SYSTEM WILL TRACK TO THE SOUTHWEST
AFTER A PERIOD OF QUASI STATIONARY MOTION. DUE TO VARIATIONS IN THE
TIME AND SHARPNESS OF THE TURN TO THE SOUTHWEST THERE IS A FAIRLY
LARGE SPREAD IN THE MODEL FORECAST TRACK. THE JTWC FORECAST TRACK IS
PLACED ON THE WESTERN SIDE OF THE MULTI- MODEL CONSENSUS. DUE TO THE
DEGREE OF UNCERTAINTY IN THE GUIDANCE, THERE IS OVERALL LOW
CONFIDENCE IN JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 150600Z IS 24 FEET. NEXT WARNINGS AT 151500Z, 152100Z, 160300Z
AND 160900Z.//

A much weaker Berguitta is passing near/over Mauritius island at the moment. A minimal Category 1 Cyclone by the JTWC, while the Meteo France La Reunion has it as a Severe Tropical Storm.
