Looks like this is tightening up again as it approaches landfall, very dangerous situation for Shanghai. Hopefully everyone there is prepared and this doesn't end up being very destructive...

I'm just surprised at how few comments it's getting. It looks like it's going to be more impactful than the last landfalling WPac system...

Like, seriously, I'm pretty sure that the Hangzhou Bay area has not had a storm hit that is as healthy-looking as this one since maybe even that 1950s one that hit Shanghai. Has Shanghai ever even been legitly hit by an eyewall like it's about to be hit? Cursory check sez no, closest calls were Wanda 1956 and Gloria 1949 and Mamie 1985. These were all pretty serious storms...

Reminds me of all the Atlantic hurricanes in 2020 that RI'ed until landfall. Truly horrible situation for Shanghai, which had been relatively lucky in recent years.

Latest wind observations from Zhoushan as of 8:30pm local time (12:30Z). You can actually discern the circulation of the typhoon passing through the area. Cool stuff from China's dense weather observation network!

Muifa has entered Hangzhou Bay and will soon make landfall over Shanghai. The degradation in structure is obvious but doesn't change much of the expected impacts on Shanghai at this point. 15Z CMA estimate: 75kts/965mb.
