dude - Seminole middle school shelter is open.. go to Park Blvd to 131st, go north to 86th and should be on the right.

As for sandbagging, I am in Redington on the Intracoastal and my home sits at five and one-half feet above sea level and I have placed 2 sets of bags (high) across my sliding doors toward the bay. My dock faces directly north so I might not be too bad because the surge element will come from the west and sw winds about 10 am they said. Considering high tide in Madeira is at 11:53 (2.53 above seal level), it will be close considering 75 mph gusts throwing water at me. I just throw them down with one corner angeled in, the next bag angeled to it and so on.. it has always worked.
