@3KillerBs has the right of it. Take down anything you can that can act as a sail - tarps, loose pieces of plastic or metal roofing, etc. Stake down everything you can. Earth augurs work great - wire stakes do not.

If you can't get these, you can wrap rope or steel cable around a cinder block, throw the block in a hole, and fill it back up with dirt - basically you are using the weight of the ground as a tie down.
If you are fortunate enough to have a pool (and given your water table, I know that's unlikely), give it a shock treatment, then throw all your loose outdoor furniture in it. Being submerged protects it from wind, and the shock treatment ensures (assuming you don't have major flooding and surface sewage) you at least have clean water for bathing or to use to flush toilets if you lose city water. Your birds can drink it too.
Bottled water for yourself, canned goods that don't require hydration (that is Chunky soup, NOT Campbell's Condensed), try to avoid rice, pasta, other things that require preparation in a pot of boiling water, and fill your freezer with water frozen in ziplocs - not only will the additional thermal mass keep things from defrosting a bit longer, but as they do, you have more drinkable water.
make sure you have a 2 week supply of any medication you take routinely, all your important papers should be gathered up and packed in the back of the car, and a "go bag". If you live on the computer, you should have your master packed in the car as well, work from a laptop or secondary for the next couple days. That way you won't lose important log ins, links, passwords, etc. Chances are, you won't need any of those things - but better to have them and not need them than to try and assemble it in the dark, while its raining, and a storm is bearing down.
I'm in the Panhandle of FL, have been thru a LOT of hurricanes when I lived in Daytona, later Tampa, and Fred missed us by a few dozen miles. We are watching Ida closely. I'm not so generous as to hope the storm track steers our way - we are living in an RV right now, and out eventual house is a bunch styrofoam forms at the bottom of the hill, awaiting concrete. We can't take a Cat 2 or 3 directly, and I've no way to move the RV.
