Verification of Severe Local Storm Forecasts Issued by the National Severe Storms Forecast Center: 1989

摘要

The SELS Unit of the National Severe Storms Forecast Center routinely issues convective outlooks and severe local storm watches to delineate areas that are favorable for development of severe local storms. The report summarizes verification of those forecasts that were issued during 1989. The threat of severe local storms was identified well via the second-day outlooks. Prediction of the location of subsequent events improved in the first-day outlooks. During 1989, 88% of the tornado-related fatalities and 85% of the tornado-related injuries occurred within valid severe local storm watches.
