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. A publication of the NOAA Home Page Design and Construction Team.
