I have a VHF amateur radio in the truck. Programmed into the memory of the radio are all six NOAA weather radio frequencies. While traveling, I tune into the strongest signal and listen to see if the forecasts are covering the area I am in. It works well enough for me to keep from traveling into a known storm area.
Inside the rig, I have a Midland weather radio with auto search for the strongest NOAA weather radio frequency. I check to see if that signal covers the area I am staying in. If not, I scan until I find the station that does cover the area I am in.
When there was bad weather in the campgrounds I have stayed in, the usual place to take shelter was the campground's bath house. All brick and concrete with very few windows.
