Mawar looking less "typhoony" at present, with Dvorak numbers dropping below 4.0. Should steadily weaken as it passes east of Taiwan and the Ryukyu Islands.

Dvorak is now 2.9/43 kts (CIMSS) and 3.5 NOAA. With very little moisture left of the center, Okinawa may not get much rainfall as it passes to the east.

That estimate doesn't agree with the official RSMC (JMA). JMA has 70 kt 10-min winds in their advisory issued at 0050Z. They are often very slow to downgrade any storm near land.

Latest SAR data looks closer to the JMA estimate with a 1 minute wind estimate of 72 kt. Looks like the west side is rather mild though.

Amy is split into April but May ACE is 35.8725 so it should be on that list.

Now that Mawar is nearing its end, I think it's safe to assess that GFS nailed the forecast, both in intensity and track.

Most guidance has done pretty well for Mawar, but the GFS (here in its interpolated AVNI version) was a to performer out to tau 96, on par with and even sometimes better than the multi-model consensuses. Definitely an impressive performance. In the extended taus, the European suite ended up taking the win, but those are taus that don't show up on a 5 day forecast.

Mawar is moving so slowly right now. The whole of South China is expected to suffer from extreme high heat for a few days due to sinking air associated with the storm.

It's starting to merge with the cold front now. Won't be tropical for much longer.

Drifting buoy "5103534" south of Ishigakijima recorded an SLP of 963.9 mb near the eye of Typhoon Mawar on May 31, 08Z. Central pressure estimate by JTWC and JMA at that time was 975mb and 965mb, respectively.

Lowest pressue in Okinawa looks like it was 972.2 at Naha.

Highest gust I saw was 32.7 m/s at Miyagijima.
