This is basically a HUGE F5 Tornado..since the tornado scale is measured by 3 second wind Gusts...
gusts 215 MPH in Irma
although that’s only possible at/near the coast since the friction of the land which makes F5 tornadoes even more impressive since they have to deal with that friction
I should add the winds a few hundred feet off the ground will be even more fast then surface(ie high rise buildings)
