Good to hear you made it home alright.
My prayers go out for those lost in ths storm and their families.
When those type of storms move through here we usually continue doing things as usual, but we always have the TV or radio on and watch or listen to the weather reports. I also have a weather alert radio that I take with us when camping. This time of year a day can be perfect and then before you know it.....
If your campground doesn't have a storm shelter then use the next best thing, such as the bathhouse. Anything is better than an RV. If you have kids, make sure they know the plan.
Here's a link to a thread by fellow FRF member Radio. It has some good info;

Good luck and happy camping.
