@CooperationIsKey: as someone who didn't grow up here, married to someone who did, i understand your anxiety and frustration. I felt that way myself when i went through my first couple hurricanes. But i quickly learned that while everyone panic buys the water and panic buys everything else, the biggest issue is probably the uncertainty of what's actually going to happen. I always get really anxious about how my car is going to handle the storm, because we don't have a garage that we can park it in. I think you're justified in being worried, but also as someone who's lived in florida her whole life, she's justified in not being too worried. My husband and i aren't too concerned right now, but we're keeping an eye on the storm to see how it's developing and where it's predicted to go. That cone of uncertainty is really no joke because it really could go anywhere within that cone. Bottom line, the best way i'd handle your anxiety is to do what you feel you need to do to be prepared. If that's planning a "hurricane party that could turn into the hurricane didn't hit us party," then so be it. Other wise what spider said is pretty good advice.
Also depending on where you are in florida will also determine just how anxious you really need to be, and also know that just because the broadcast today says it could hit your area, doesn't mean that it will say that tomorrow. The closer the storm is, the better the meteorologists are at predicting where it's going. For example, tuesday and wednesday are when i'm going to really be watching the forecasts because that's when it's currently estimated to hit florida. Yesterday it said it would be Wednesday, but it's a slow moving storm.
