When a thunderstorm moves through your area, be alert for tornadoes. A tornado watch is issued by the National Weather Service when there is a threat of tornado conditions. You may still have time to take precautions. During a tornado watch, listen to a battery-operated radio or television for weather reports, and be prepared to move to shelter if you hear a tornado warning. A tornado warning is issued when a tornado has been sighted or indicated by weather radar.
Mobile homes are particularly vulnerable to tornado damage, even if securely tied down.
When a tornado warning is issued, take shelter in the lowest level of a building with a strong foundation. If shelter is not available, lie in a ditch or low-lying area a safe distance from the unit. Learn and practice tornado preparedness. The thunderstorm is nearly over, when suddenly, the emergency radio sounds the tornado warning alert. You may have only minutes or seconds to seek shelter.
