Those are definately legitimate concerns in the midwest near a river during a flood, or even here during a hurricane if you live near the ocean. Fortunately they have mandatory evacuations of everyone out by the beaches so we hope no one will drown.
Orlando is inland so we expect about two feet of water or so on the ground around here so we can at least mark drowning off the list of problems tomorrow. Pissed off Gators, Snakes and Fire Ant Floaties are about as bad as the water part should be here.
If anyone is goofy enough to NOT evacuate in the beach areas where the hurricane is expected to make land fall then I would say they are pretty much toast. They tell us that storm surge of about 14 feet is expected but could be higher. Imagine a two story tall wall of water coming at you at 110 Mph…. Not too appealing.
