A tornado watch is issued when weather conditions are favorable for severe thunderstorms, which can produce tornadoes. A tornado warning is issued when a funnel cloud has been sighted and, then that happens, you should take shelter immediately: go to the basement or lowest floor of a building; if in a mobile home, go to the nearest building or storm shelter; fasten seatbelts while driving and, if outside, lie down in a low, flat area and cover your head with your hands.
