DebJim, I moved here from earthquake country, and earthquakes have no warning at all, so I feel relatively safe living here. The most important thing is that you know the storm is coming. The weather stations have warned you for at least 24 hours that a severe thunderstom is coming, and then you can see the dark sky, and it's raining & windy! Time to pay attention!
After you move in, you need to buy a weather alert radio. You can take it to the fire station to have it programmed for your area. Yes, you can do it yourself, but the guys at the fire station are so danged cute! It's well worth the trip just for the eye candy!
You can also sign up to receive a "Code Red" phone call from the sheriff's department. Here's the link:
Sumter County, FL - Official Website - Code Red Weather Notification System
This is good to have on your cell phone, because you can get alerts while you're golfing, attending art class, etc. On the other hand, you'll also get the alerts after you go back north & you're nowhere near The Villages.
Next, you decide which area of your home is most secure against flying debris.. the bathroom, the walk-in closet, etc...
Stock your emergency supplies in a tote bag, flashlights, batteries, radio, water, wine, cat food, etc... so you can grab them and head for the closet when the television tells you to get in the closet. The television stations here have excellent severe weather coverage. They can pinpoint the path of destruction by streets in a neighborhood!
Then put on your headphones and don't worry about it. These are the things I do when I know a storm is imminent. I'm sure other folks here have more ideas.
