Pronounced westward wobble in the last few frames should send eyewall onshore soon

this is making an attempt to intensify just a bit more as it makes landfall.

I'd estimate 130 KT now as it has become a bit more symmetrical

Rammasun is the second strongest typhoon to EVER hit China, based on one-minute sustained winds, only behind Saomai 2006.

Saomai was 130 kt at landfall according to JTWC.
According to Chinese data, strongest typhoon ever hit China was 7315 Marge, which made landfall at Wenchang, Hainan. Saomai is the strongest hitting Mainland China.

Lowest measured SLP in both Marge and Saomai was around 935 to 945hPa

If the above observation of 917hPa is confirmed it will make Rammasun much more intense than any of the strongest typhoons to hit mainland China in modern history

Certainly looks thrice as good as it ever was before landfall in Southern Luzon... I'd be surprised if JTWC wouldn't call a STY.. It's interesting that few typhoons in the SCS are recognized as "super typhoons" by JTWC and other asian agencies that also use that term. The only STY in SCS I can remember is Chanchu in 2006.

Here are some clips before and after the storm kicked in... It's more of "after" clips but the first few clips during the storm are just crazy... The wind was crazy obviously but the people trying to go in and out of the building were just as crazy...

this is a landfall over northern Hainan Island

I would agree with a 135 KT landfall intensity based upon the available imagery
