Looks like RI has begun. Wrapping up very nicely with strong banding in all quadrants.

Not liking that presentation, that really doesn't bode well for anywhere close to land...

I agree RI may well be starting, can see this ramping up into the 105-115kts range by LF quite easily.

Never 55kts right now though, could easily add 25-30kts to that figure right now IMO.

Yeah thats looking really impressive now Hurakan, I think people in Madagascar need to prepare for a big landfall now, probably got to get ready for a 3/4 landfall IMO....so soon after Yasi!

Its inner core really has come together very quickly which is not a good sign!

06z GFS runs this down Madagascar's east coast briefly going inland before exiting and heading southwards.

That frankly probably is a major hurricane, that presentation is screaming a Major hurricane to be fair!

JWTC going to have to really lift up the intial estimate from 12z...90-100kts sounds probable.

Yeah its got the look of a explosive system, the models have been quite keen on really strengthening this system upto landfall and it seems to be coming off...

No way this is anything below 100kts right now.

That figure of 5.5 sorta backs up what we've been saying here about this likely being in the 95-105kts range, its looking markedly better then it was just 12-18hrs ago, as the comments confirm nicely.

REMARKS:
122100Z POSITION NEAR 15.6S 53.2E.
TROPICAL CYCLONE (TC) 13S (BINGIZA), LOCATED APPROXIMATELY
420 NM EAST-NORTHEAST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED
WEST-SOUTHWESTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. ANIMATED
INFRARED SATELLITE IMAGERY AND A 121716Z 91H SSMIS MICROWAVE
IMAGE SHOW DEEP CONVECTIVE BANDING FEEDING INTO A 28 NM CONCENTRIC
EYE. THE CURRENT INTENSITY OF 85 KNOTS IS BASED ON DVORAK ESTIMATES
RANGING FROM 77 TO 90 KNOTS FROM PGTW, KNES, AND FMEE. ENVIRONMENTAL
ANALYSIS REVEALS THAT FAVORABLE SEA SURFACE TEMPERATURES (>28 DEGREES
CELSIUS) AND AN ENHANCED POLEWARD OUTFLOW CHANNEL, ASSOCIATED WITH A
TRANSITORY MID-LATITUDE TROUGH TO THE SOUTH, HAS ALLOWED FOR RAPID
INTENSIFICATION OVER THE PAST 12 HOURS. TC 13S IS CURRENTLY TRACKING
WESTWARD ALONG THE NORTHERN PERIPHERY OF A WEAK STEERING RIDGE BUILDING
TO THE SOUTH. TC BINGIZA IS FORECAST TO CONTINUE TRACKING IN A
GENERALLY WEST-SOUTHWESTWARD DIRECTION AND CONTINUE TO INTENSIFY BEFORE
MAKING LANDFALL ALONG THE NORTHEASTERN COAST OF MADAGASCAR NEAR TAU
36. THE SYSTEM IS EXPECTED TO DISSIPATE OVER THE RUGGED TERRAIN OF
MADAGASCAR, BUT THERE IS THE POTENTIAL FOR REMNANTS TO RE-DEVELOP IN THE
MOZAMBIQUE CHANNEL IN THE LATER TAUS. NUMERICAL MODEL GUIDANCE IS IN
GOOD AGREEMENT; THEREFORE THIS FORECAST IS CLOSE TO MODEL CONSENSUS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 121800Z IS 23 FEET. NEXT WARNINGS
AT 130900Z AND 132100Z. REFER TO TROPICAL CYCLONE 14S (FOURTEEN) WARNINGS
(WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//
