I think JTWC's estimate of 120 kt for Freddy seems a bit conservative. Maybe 130 kt would be a more reasonable bet based on IR and MW.

Looks like that the 185 mph winds are gusts ...

On the brink of T7.0 eye just needs to warm. Given the strong ridging will keep this west or west north west and annular structure, a ridiculous ACE out of this seems likely.

Looks like JTWC is putting too much trust in the GFS, taking it too much to the south over the next 5 days. GFS has a history of recurving cyclones too soon.

Bulletin of February 15 at 10:41 p.m. local time in Reunion (9.41 p.m. local time in Mayotte):


INTENSE TROPICAL CYCLONE number 7

(FREDDY)

Maximum winds (averaged over 10 minutes) estimated at sea: 205 km/h.

Estimated maximum gusts at sea: 285 km/h.

Estimated pressure at the center: 939 hPa.

Position on February 15 at 10 p.m. local time: 14.7 South / 83.6 East.

Distance from the Reunion coast: 3020 km to the sector: EAST

Distance from Mayotte: 4150 km to sector: EAST

Movement: WEST, at 22 km/h.

System Information:

- Intense tropical cyclone FREDDY remains a particularly powerful and compact tropical system, generating extreme winds near the center. The zone of influence of the cyclone is reduced - few effects felt beyond 200 km from the center.

- It is moving rapidly in a general westerly direction and will reach the western part of the basin at the beginning of next week.

- On this trajectory, FREDDY will be approaching the Mascarenes from the North-East from Sunday with a possible influence of the weather for Rodrigues Island. Given the uncertainty of the trajectiure at this time, it is still too early to comment on the possible expected impacts. The Rodriguans are therefore invited to start monitoring the evolution of the situation.
