What is a Tornado?
A tornado is a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes have rotating winds of 250 miles per hour or more. They are capable of causing extreme destruction, including uprooting trees and well made structures, and turning normally harmless objects in deadly missiles. Most tornadoes are just a few dozen yards wide and only briefly touch down.
Why talk about Tornadoes?
Tornadoes have been reported in every state, and though they generally occur during spring and summer, they can happen any time of the day or night, they are most likely to occur between 3:00 and 9:00 p.m.
There are no areas immune to tornadoes; they have been reported in mountains and valleys, over deserts and swamps, from the Gulf Coast into Canada, in Hawaii and even Alaska.
Regardless of the location or time of year, if conditions are right, a tornado can happen.
What can I do to prepare for a Tornado?
In addition to completing the 4 Steps to Safety, do the following:
- Use a NOAA Weather Radio with a tone-alert feature, or a portable, battery-powered radio (or television) for updated emergency information of watches and warnings issued in your area.
- If planning a trip or extended period of time outdoors, listen to the latest forecasts and take necessary action if threatening weather is possible.
Watch for tornado danger signs:
Dark, often greenish sky a phenomenon caused by hail indicating a tornado may develop. Wall cloud, an isolated lowering of the base of a thunderstorm. Large hail. Tornadoes are spawned from powerful thunderstorms and the most powerful thunderstorms produce large hail. Cloud of debris, funnel cloud, roaring noise. Get training – take a first aid class from your local Red Cross chapter.
