It has to be getting pretty wild on KW though. If not damaging winds, rain and coastal flooding. I would say this would be a hurricane party night there on Duval, but for that Duval St is probably going to be flooded if it isn't already.


Sloppy Joes seems to be still quite busy based off the cam :)

Though note that swampy areas like you get with the Everglades or coastal Louisiana have less friction than dry land. IIRC, Wilma might have slightly increased wind speed as she crossed the Florida peninsula at the Everglades.



Wilma increased as she crossed Lake Okeechobee.

Doesn’t pressure usually rise during EWRC?

Winds are reduced, pressure can get lower. Remember Ike with super low pressures and 'just' cat 2 winds. One of the epic fails of the saffir simpson scale. Once eyewall recovers winds should start to rise again.
