You probably managed to think of everything. I live in central Georgia, and this last hurricane season we had some pretty bad storms. I did nothing different for my hives, and the bees just stayed in from the rain, and I had no problems. I did loose some roofing on our greenhouse though from the winds. I'm sure our storms aren't as bad, but they were bad enough here that an old building in town blew down, some trees were blown over (roots and all), had flooding, and branches that took down lots of power lines. But the hives I guess are low enough to the ground, and compact, so nothing happened.
