JTWC still awkwardly high at 956 mb/low at 90 kt given MF's estimation.

It could be upwelling. This storm hasn't moved a whole lot over the past few days. Fanele may have just reached her peak.

The JTWC only updates every 12 hours though?

My guess for peak 1-min winds was 120 kt (at 1200Z) based on all the data out there. It has probably weakened some since then, I am guessing about 110 kt now. My guess for the current pressure is 944mb.

JTWC best-track is, as per DOD requirements, six-hourly.

And of course as it gets closer to landfall, the weakening begins. Based solely on that last UV image, I would estimate 80-85 knots 1-minute. It's amazing how quickly small circulations can explode and then weaken - just 48 hours ago Fanele was barely a tropical depression.

IR almost appears to show a double eyewall. Microwave doesn't really show it though.

Definitely weakening now.

EXTREME CONDITION COULD BE START BEFORE THE END OF THE NIGHT.

PRESENT TC WAVE ARRIVED IS JUST UNDER 3.5M (MAX. 7M HIGH) BUT IN FEW TIME FROM THE WEST SIDE ON ALL COAST POSITION, SPECIALLY FROM REHARAKA TO MOROMBE AND FEZA TO TOLIARA, TC WAVE BEGIN EXTREMLY DANGEROUS AS PROBABLY MORE THAN 6M HIGH (MAX.>12M HIGH).

WIND EXPECTING MORE THAN 150KM/H (UPTO 200KM/H).

FLOOD IS EXPECTING ON SEVERALS DISTRICTS: ANTSALOVA, BELO-TSIBIHIRINA, MAHAVO, MORONDAVA AND MOROMBE.

ORANGE CONDITION ON ZONE MPSvc5:

TC FANELE COULD BE TAKE A DIFFERENT ROAD THAN PREVIOUS FORECAST AND CROSS SOUTH MADAGASCAR AXIS BASED FROM NORTH OF MORONDAVA (AMPATAKA) TO TOLAGNARO.

12 meter (40 foot) waves? What would the storm surge be for a typical Category 3 storm approaching from that side of Madagascar?

It still looks quite solid on microwave images. I would guess the 1-min winds are around 100-105 kt.

For this basin, JTWC forecasts every 12 hours, but the intensity and position is updated every six hours. Most of the time you can see the new intensity and position on the NRLMRY imagery shortly after the beginning of each forecast cycle (00Z, 06Z, 12Z, 18Z).
