Super typhoon Hagibis has now restrengthened back to equivalent-CAT5 after a transient drop in strength due to an eyewall replacement cycle. And the structure on this system is tremendous!

Super Typhoon Hagibis currently packs sustained 160 mph (257 km/h) winds, almost as powerful as Hurricane Dorian in early September. Latest imagery by the Himawari-8 satellite reveals a truly impressive super typhoon:

See the comparison below between the size of Hagibis’ eye late on October 7th (local) and late on October 9th! Tight pinhole eye on Oct 7th, with Hagibis already a CAT5-equivalent super typhoon. The eye tightened to a diameter of less than 10 km, possibly even <5-6 km before an eyewall replacement cycle took place and Hagibis transiently weakened to equivalent-CAT4. A larger (current) eye formed and Hagibis has restrengthened to equivalent-CAT5.

Latest model guidance suggests Super Typhoon Hagibis will retain its full power for at least another 12-18 hours, before weakening slightly.

Hagibis is on track for landfall near Tokyo early on October 12th. By then it will have weakened to an equivalent CAT2 or CAT3 system, still a powerful and potentially extremely dangerous tropical cyclone.
