2 Example of consistent wording used within the tornado warning text for East Central Florida Tornado Warning Situation Number 6. The threat is often manifested in families of short-lived F0 or F1 tornadoes that are either spatially or temporally removed from the traditional threats of hurricane wind and surge. Occasionally F2 tornadoes occur which cause the majority of tornado-related casualties and property damage. On average, parent cells do possess mesocyclones but of a compact physical dimension making them more challenging to detect with radar. Wording within the warning text emphasizes a tornado threat that stretches beyond the vicinity of the original warning location or the pathcast of a particular suspect cell due to faster storm motions and the potential for multiple events.
Tornadoes are usually short-lived and occur in families.
In fact, successive tornadoes are possible if organized within a dominant band. Interestingly, on many occasions the tornadic cells are void of electrical activity. If confidence is increased through improved radar sampling or a report is received, more emphatic wording is used and directed at a particular cell for persons in its path. The template structure was designed so that the forecaster, after determining the situation, is guided through a series of options used to compose the warning text. Warngen has the ability to linearly extrapolate storm motion and state where it will be located at certain times during the warning valid period.
