Data from some Chinese-built weather stations in the Spratly Islands would be really useful now.

Rai now has a radial outflow.

Interesting what would the 2nd peak be, eye temp for the very first time has went to + from ADT.

2021DEC18 084000 6.7 933 132 6.7 7.0 7.3 1.3T/6hr OFF OFF OFF OFF 4.45 -79.07 EYE 17 IR 19.1 11.59 -113.98 ARCHER HIM-8 33.7

Would be amazed if it went to cat 5 again especially this sea has only 3 cat 5s on record or even beat the 1st peak.

I still remember the shock when I saw Rammasun intensifying into a cat.5 (operationally 135kt) before making landfall over Hainan. I didn’t expect I’d see that again, not to mention in December.

Are there any other stations in the Spratlys other than Song Tu Tay (48892)?

Don't expect data to be publicly available, but China opened three meteorological stations there in 2018 (in Yongshu, Zhubi, and Meiji reefs). The article says there's even a weather radar there. Might be politically controversial but I think it's cool from a meteorological standpoint!

Hey uh, what's everyone's intensity estimate for Rai's (first) peak and do you agree with the JTWC's/JMA's estimate?

There's absolutely a weather radar on those islands. I've seen a lot of radomes on those reclaimed island when I was browsing google earth pro.

140kts/105kts from JTWC/JMA sound okay to me. It could've been higher if not for the unrelenting shear (which Rai had surprisingly overcome) and the EWRC prior to landfall. Still its intensity was enough to pack a punch. People in the Visayas and Mindanao are saying that Rai was more intense than Mike.

[mrbagyo]

5 knots increase. Lol
