We once sat out straight line winds of 75+ mph in Wild Blue, on the trailer, attached to the truck. In an RV park. The forecast was for thunderstorms, and we did have the bow pointed into the wind. It was not pleasant. This was not in a hurricane and the winds, at their worst, lasted less than an hour.
Living in a hurricane zone, I have seen the results of boats on stands and trailers with significant winds... toppled like dominoes. If 100 mph winds came from the side, I would certainly think that a 25 would be at risk of tipping over. With the winds in the first paragraph, a couple semi-trucks tipped, as well as an empty train car. Keep the bow into the wind, stay attached to the truck. Ground anchors (screwed in) may help. Keep in mind that as a hurricane passes, the winds will change direction.
The other issue isn't just the wind, it is what is IN the wind. Hurricane Dolly (a Cat 2) passed right over our house. The hurricane shutters kept the house from being breached, but we did find a roof shingle (not ours) that had pierced a piece of our siding. You have a lot of glass on a 25. The safest bet is what Tom suggests: get away from it; once north of Florida, consider going west.
Another issue isn't just getting you and some stuff out of harm's way, it is having a plan for when you return... generator, fuel, a room air conditioner, plenty of water, and food that will keep.
Wishing you a safe journey away from it, and hoping for the best on your return.
