Late reply here too, but unless I was evacuating 24 hours or more before the storm hit and could afford to stay away for two or three days, I wouldn't ride the bike. Many people's jobs don't allow the luxury of leaving that far in advance or waiting for the weather to clear up before returning.
If you are leaving when the evacuation orders are being issued, you're going to be stuck in major stop-and-go traffic as well as almost certainly going to be caught in some very bad weather both on the trip out and the trip back. The thunderstorms and gusty winds often start well in advance of the storm and can persist for a day or so after.
That being said, I'm not sure what I'd do with a bike in a hurricane. If you don't have access to a garage, I guess I'd make the bike as stable as possible with the center stand or front/rear stands on level concrete and hope for the best. If possible, maybe put it between two buildings, facing so that the wind will hit it from the front or rear and not from the sides.
