What do you guys do with bad weather like tornados with not much warning?
Especially those of you that full time, that is your home-is this a big concern or not ?
Drink Heavily.
But seriously... Having lived in a couple mobile homes in my previous life, you can find two groups of folks. The ones who head to the mall when severe weather is coming, and those of us who will grab a couple beers and stand in the street with their neighbors, looking at the sky and asking each other, "how bad do you think it'll get?"
The weather radio is a must and is always on. I have the local "weather underground" website bookmarked as well, and monitor it anytime there is unsettled weather around. I can say in almost 5 years, full timing in North Carolina and Florida, we've not abandoned ship yet. Campgrounds are generally not very well equipped with facilities for storm shelters. Generally, by the time you know that you should have left your home and property behind, it's too late to leave or it's over with.
The closest call we ever had was in NC during a tropical storm event. The storm actually built in intensity over the course of a day, but kept getting better and worse as the rain bands kept coming. Around 11PM, we had gone to bed and there was a very near lightning strike around 1AM. We both jumped out of bed, dressed, and were checking to see if we were alive. We didn't lose power, but could smell electrical/electronic smoke in the camper. I spent an hour looking for the source of the smell, but couldn't figure it out. Everything worked fine. The storm let up a bit, so we went back to bed after an hour. About 3:30AM, something awoke my wife, and I found a Surge Protector Power Strip under the kitchen table with a 2-foot flame, licking the bottom of the dinette table and producing a very sooty (plastic) smoke. I grabbed it by the cord and tossed in the sink.
When it's your home, your always concerned. Having someplace to seek shelter and being willing to do so can be difficult for some of us. Either way, someone can criticize (would'a, could'a, should'a) but you have take your stand.
