What is a Severe Thunderstorm?
A severe thunderstorm is a storm that produces a tornado, reaching winds of at least 58 mph, and or hail at least ¾ inches in diameter. Structural wind damage may imply the occurrence of a severe thunderstorm. A thunderstorm wind equal to or greater than 40 mph and or hail of at least ½ inches is defined as approaching severe.
Severe Thunderstorm Watch
This is issued by the National Weather Service when conditions are favorable for the development of severe thunderstorms in and close to the watch area. The size of the watch can vary depending on the weather situation. They are usually issued for a duration of 4 to 8 hours. They are normally issued well in advance of the actual occurrence of severe weather. During the watch, people should review safety rules and be prepared to move to a place of safety if threatening weather approaches.
Severe Thunderstorm Warning
This is issued when either a severe thunderstorm is indicated by the WSR 88D radar or a spotter reports a thunderstorm producing hail ¾ inch or larger in diameter and or winds equal or exceed 58 miles an hour; therefore, people in the affected area should seek safe shelter immediately. Severe thunderstorms can produce tornadoes with little or no advance warning. Lightning frequency is not a requirement for issuing a severe thunderstorm warning. They are usually issued for a duration of one hour. They can be issued without a Severe Thunderstorm Watch being already in effect.
