Hopefully it will stay a just a tropical depression. Pray hard.
I have lived through tropical storms in our Seagrove house, no big deal, just lots of wind and rain. We never even lost power in those. We did have a lot of wind driven rain, the house moaned and groaned at about 2:00 a.m. when I was there by myself during one.
* Make sure everything outdoors is secure, garbage cans, furniture, anything that can get blown around.
* Watch windows and doors for wind driven rain intrusion.
(We had water come in around our third floor french doors that faced the gulf, we had those re-stripped and they are fine now.)
Hang on tight! It can be interesting.
Oh, just ask Bobby J, now is a grayt time to go look at property during/after an event to see what it does, you will know if it floods.
