1. get a weather radio with S.A.M.E.
2. when you arrive at your destination, find out what county you are in and get an Atlas and look at your location and what towns are adjacent, especially the ones south and west of where you are.
3. Ask the office where the storm shelter is in the campground. If they don't have one in the campground, ask where the nearest shelter is located.
4. when you arrive at a campground, search for the weather station that is the best reception. (you do not have to program the county if you don't want to.
5. Know the difference between a tornado watch and tornado warning.
6. Keep your cell phone charged and put your wallets near the exit of the RV in case you need to go to a shelter.
7. If you hear a severe thunderstorm warning or a tornado warning, don't hesitate, go to the shelter! Better be safe than sorry.
We have had to evacuate 3 times: once in Florida, once in Kansas City (for 2 nights) and once in Cincinnati (for 2 nights).
We watch the weather a week in advance where we're headed and will change our travel plans if the weather looks bad there or on the route.
Just use common sense and don't get caught unaware of the weather.
My son lives in Oklahoma. He said at work they told them that most of the time (not 100%) a tornado will move from the southwest toward the northeast. Once in Illinois, we hopped in the toad and drove due south to avoid a storm. Went to dinner, waited it out and drove back to the RV.
