Isolated tornadoes are possible today as a strong line of storms tracks across the forecast area this morning and early afternoon. What to do if caught out driving during a tornado warning: Get off the road. The best option is to drive to a designated shelter, basement or safe room. The next best option is a small, windowless room or hallway on the lowest floor of a sturdy building. 2) What No To Do: Do not seek refuge in a vehicle, outside or under an overpass. A highway overpass does not provide safety from a tornado. Do not seek shelter under an overpass or a tree. This puts you at greater risk of being killed or seriously injured by flying debris from the powerful tornadic winds.
