In my first month on our full-timing trial run I sat through a storm at an rv park in Pacifica CA (outside of SF, on a bluff overlooking the ocean). 60+MPH gusts.
The bad part was, it all started about 4am while I was asleep. I had a dream that a flood came down through the park and was carrying the Airstream towards the bluff. I jumped up and started to remove the screen for the emergency window to get out. While doing that, the window started shrinking until it was too small to fit through, but I could see through it and the Airstream was hanging over the edge of the bluff, water gushing over the edge all around me. That's when I woke up, and realized the storm had started. Felt like I was in a crazy wind tunnel or something, it was definitely rocking, not in a good way.
A couple months later we returned to the park and my wife got to experience storm 2.0 in the same location, same or worse winds.
For those storms, people in smaller trailers were definitely leaving. I think if I ever see a forecast for something worse than that I'd try to get out of the storm path.
