Structure appears to be quickly improving upon approach to Taiwan.

Northerly Wind Shear combined with Dry Air?

Looked like the eye kept moving north while the system's overall envelope stalled. Don't know if I've ever seen anything quite like that before.

Re: WPAC: CHANTHU - Typhoon
Man Taiwan has the luck of the devil to have avoided a direct hit like that. As for the Batanes they're still getting hammered by the trailing bands specially Itbayat.

Re: WPAC: CHANTHU - Typhoon
The current organization/intensification might be being aided by the topography of Taiwan combined with the TC's poleward motion just offshore.

T6.5. Probably 125 is the most reasonable estimate.
What a strange looking storm — and what a close call for Taiwan. It’s just a few dozen miles from a 120-130 kt landfall near Tapei.

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.

Re: WPAC: CHANTHU - Typhoon
It’s precisely because it won’t make landfall over Taiwan that it can intensify. If Chanthu drifts west, dry air from the Central Mountain Range will be wrapped into the core before landfall. This effect is more significant on small TCs. Nepartak’s central pressure rises from 910mb (recorded by NTU buoy) to 940mb (recorded by Taiwan AWS) at landfall.

Re: WPAC: CHANTHU - Typhoon
Taiwan dodges another direct typhoon hit, interesting, isn't this the longest typhoon drought for them?

Re: WPAC: CHANTHU - Typhoon
Very close call for Taiwan. The eye passed just ~30km (and eyewall just ~20km) from the country's northeastern tip. The drought of typhoon-strength landfall there that started in 2018 is remarkably long for such a typhoon-prone location!

Re: WPAC: CHANTHU - Typhoon
Didn't go through obs for Taiwan, but looks like Chanthu brought a maximum gust of 88 kt with a minimum pressure of 989.4 mb to Yonaguni as the system passed a good deal to the west of the island.
