Listen to local radio and television or NOAA weather radio for additional information. Severe weather is occurring or will occur soon. Be prepared to take action. In a building, an interior hallway on the lowest floor away from windows is usually safest. Never try to outrun a tornado - on foot or in a car.
Lightning kills more people each year than tornadoes.
During a thunderstorm protect yourself by seeking shelter indoors away from windows. Close the windows and doors if you are in a building or car. Turn off heating and cooling systems, including windows and attic fans. Close all doors and windows. Do not use fireplaces.
