Tornadoes

What it is

A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. Tornadoes can damage homes, businesses, trees, vehicles, roads, and utilities.

Why it matters in Tennessee

Tornadoes can happen in Tennessee during any season and at any time of day. Tennessee has more nighttime tornadoes than any other state, with more than half of the state’s tornadoes touching down after the sun sets. Nighttime tornadoes are especially dangerous because people may be asleep, unable to see the storm, or less likely to receive a warning. 

Because of this risk, every household should have more than one way to receive weather alerts, including at least one alert method that can wake you up.

What to do before

• Identify your safe place before severe weather happens.
• Choose a small, interior room on the lowest level of a sturdy building.
• Stay away from windows, doors, and outside walls.
• Have more than one way to receive warnings, including alerts that can wake you up.
• Keep shoes, a flashlight, and emergency supplies near your safe place.

What to do during

• Go to your safe place immediately when a tornado warning is issued.
• Cover your head and neck with your arms, a helmet, blanket, or mattress.
• If you are in a mobile home, leave for a sturdier shelter if you can do so safely before the storm arrives.
• Do not try to outrun a tornado in a vehicle.
• Stay sheltered until the warning has expired or officials say it is safe.

What to do after

• Watch for downed power lines, broken glass, debris, and damaged buildings.
• Check yourself and others for injuries.
• Use text messages when possible to keep phone lines open.
• Avoid damaged areas unless officials say it is safe to return.
• Report damage when instructed by local officials.
