Well I've got three answers to that.

The most severe weather I sheltered in place from was hurricane Fran. Fortunately it didn't rearrange my family's own chunk of the forest too bad but some trees were thrown on a few houses.

The most severe weather I've experienced unsheltered was Hurricane Noel. The dumbfuck 20 year old I used to be decided to ride a motorcycle from Daytona to West Palm Beach for no particular reason. I got my giblets rinsed. That wasn't the most unpleasant weather I've ever been in though, I rode that same motorcycle through a freezing rain storm about 3 years later. I kept having to pound my fist into my visor to de-ice it.

The worst aftermath of weather I've seen but wasn't personally in was an EF-3 tornado. It was on the ground for over an hour, it cut a path a thousand feet wide and easily 50 miles long, tearing through forest, neighborhoods and commercial districts. I worked as a flight instructor at a nearby airport, so afterward I got a fairly good look at the damage path from the air. It looked kind of like a logging operation, you know how they'll take a parcel of land and clear cut it either for development or for the timber? Except smeared across the landscape crossing roads and taking houses and buildings with the trees.
