"A limited program was begun in 1979 to develop a measure of watch/warning forecast performance for flash flood, winter storm and high wind. Weather Service forecast offices provide verification logs to national headquarters for this purpose. These logs consist of issue time, valid time, lead time, area, verification for watches and warnings, and events that occur in the absence of a watch or warning. A total of 43b flash flood, 186 winter weather and 111 high wind events were reported on the logs in 1982. Collectively, 10 percent of those events occurred without a watch or warning being issued. Of the total warnings disseminated 78 percent showed positive verification, but 41 percent of those were issued with an event in progress. In 1983 a total of 414 flash floods, 147 winter weather and 80 high wind events were reported on the logs. Collectively, 11 percent of those events occurred without a watch or warning being issued. Of the total warnings disseminated 79 percent showed positive verification, but 36 percent of those were issued with an event in progress."
