Impressive given how it relatively weakened, makes you think it peaked at or just below 900mb.

That eastern eyewall brutalizing Itbayat, will probably destroy what Meranti didn't few years ago..

Re: WPAC: CHANTHU - Typhoon
935 lines up with CKZ if you assume an intensity of around 125 knots.

Re: WPAC: CHANTHU - Typhoon
Can we use radar velocities from Taiwan radar to estimate winds in Itbayat? The dBZ is off the charts.

Are Taiwan's NTU buoys near Orchid island still working?

But it needs to go or else East Asia will be in bigger trouble
If I may guess, the reason for Chanthu's degredation is the steep drop in SSTs

Re: WPAC: CHANTHU - Typhoon
So the JTWC drops it down 5 kt when it’s clearly strengthening, but then keeps it as a Cat 5 when it’s clearly weakening?! What is up with them?

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Did you read the discussion? At the time of the analysis, it was actually looking better, as noted by others on this site who noted the eye was clearing out again. But it didn't last long. Also it takes time for a system to spin down, just because the satellite presentation degrades does not equal an instantaneous reduction in the wind speed.
