What a tornado warning means

A tornado warning is the most urgent alert the National Weather Service issues for severe storms. It means a tornado is happening or is about to happen, either because a spotter or the public has seen one or because Doppler radar shows strong rotation that can produce one within minutes.

What to do

• Go to a basement or storm shelter right away. If you have none, use a small interior room on the lowest floor, away from windows.
• Protect your head and neck with your arms, a helmet, a mattress or heavy blankets.
• Leave mobile homes and vehicles for a sturdy building if you can reach one safely.
• Keep a phone or weather radio with you to know when the warning ends.
