I'm 28` above sea-level, If the projected storm surge is even close to that I'm out, If its not then I'm staying, I was down at Casey key after Charlie doing emergency work, Pretty nasty stuff.
don't forget about the tornadoes. Downed power lines. Trapped in your car trying to leave the area.
If leaving your house what could you rig up to leave a lower head running for a day or two if power does go out?? Is that possible?
Get a battery powered bubbler from the fishing section at walmart they last quite a while and will keep oxygen in your tank. They have saved me from many power outages.
