Storm Watches and Warnings
Watches and warnings for storms and tornadoes can differ. Storm and tornado watches mean that severe weather is possible, within a given amount of time. Watches usually last between four and six hours. Warnings on the other hand, mean severe weather has been detected or observed, and it is moving in a given direction. The Storm Prediction Center in Norman, Oklahoma has the authority to issue watches. Severe thunderstorm and tornado warnings are issued by the local offices of the National Weather Service.
