It really depends on a lot of things, and it's impossible to know in advance.
I lived in Florida during the insane 2004 and 2005 storm seasons. I was more or less hit by Frances and Jeanne -- lost a week of school to each one. (We call it hurrication.) But my house never lost power at all during or after those storms.
On the other hand, we got whalloped by Wilma in 2005. My house didn't have power for two weeks (and no school for two weeks again), but I know that we were some of the last people affected to get power back.
Don't believe everything people are saying about electricians. Power companies have emergency response plans to bring power back on after a natural disaster, and they're moving trucks and equipment to strategic locations right now so they're ready after the storm. After all, this isn't going to be too far from what happens when they have to fix power lines after a really large blizzard.
(Plus, many power lines in Florida are buried underground but most aren't around your area. This makes them more vulnerable to storm damage, yes. But it's much, much easier to fix damage to a cable that isn't underground.)
