I looked at at a few wunderground stations around there — most weren’t reporting wind speeds for Sunday but one did show a max of 80 mph. So I believe 100 MPH gusts were possible in nearby locations.
I just did a search around the current location (27.9N 82.1W) on Weatherunderground PWS and likewise found many haven’t reported in many minutes. Not sure if that is normal in that area. Most PWS use RapidFire and update every few seconds. Mine does. Anyway, the ones that are reporting wind in the area have winds in the 30s and gusts in the 40s and 50s. Lots of hype for nothing. If anyone can’t handle those winds...
I looked at the National Hurricane Center. They reported a maximum sustained wind speed for Sebring of 59 m.p.h. The highest that the NHC reported for anywhere in Florida was 88 m.p.h. at Naples. I don't think reports of 100 m.p.h. winds in Sebring are credible.
