Tornadoes are one of nature's most violent storms. In an average year, 800 tornadoes are reported across the United States, resulting in 80 deaths and over 1,500 injuries. A tornado is as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long.

Tornadoes come in all shapes and sizes and can occur anywhere in the U.S at any time of the year. In the southern states, peak tornado season is March through May, while peak months in the northern states are during the summer.

The National Oceanic and Atmospheric Administration issues tornado watches and warnings and conducts research to better understand these powerful storms and improve forecast techniques. Tornado watches are issued by NOAA's Storm Prediction Center, located in Norman, Oklahoma. Warnings are issued by local National Weather Service forecast offices. Meteorologists rely on weather radar to provide information on developing storms. The network of Doppler radars that blankets the nation detects strong rotation within the storm. Forecasters use this valuable data to determine the likelihood of a tornado and issue the appropriate watches and warnings.

Tornado safety and preparedness are key to protecting your loved ones during a tornado. Be sure to stay tuned to NOAA Weather Radio for warning instructions; take cover immediately if a tornado is imminent; go to a designated shelter in a basement or interior room such as a closet or bathroom; if you are in an automobile, mobile home or in the open, seek shelter in a sturdy structure or get down in a ditch or depression; always protect your head and body from flying debris.
