TORNADO WATCH VS. WARNING



A Tornado Watch is issued when conditions are favorable for a tornado. It doesn't mean severe weather is imminent.

A Tornado Warning is issued when either a tornado has been spotted or a radar has picked one up. If you are in an area with a tornado warning, it's time to act immediately. Get to a safe space such as a storm shelter. If you don't have one, the best option is usually in the basement or the middle of a building, away from windows, preferably in an area with reinforced walls.
