Participants will know the difference between flash floods and backwater or stream flooding. Participants will be familiar with typical forecast lead-times and emergency personnel reaction times associated with each type of flood. Participants will be able to use Mesonet data, radar precipitation estimates and stream gauge reports to recognize the precipitation patterns appropriate to each type of flood. Participants will be familiar with, obtain, and be able to interpret forecast products produced by the Storm Prediction Center, the NWS Arkansas-Red River Basin River Forecast Center, and the local National Weather Service Office with warning responsibility. Participants will be aware of, display, and apply WWW flood-related information disseminated by OK-FIRST, the Arkansas-Red River Basin Forecast Center, the Tulsa District of the U.S. Army Corps of Engineers, Oklahoma District of U.S. Geological Survey, area National Weather Service offices, and the Oklahoma Mesonetwork. Participants will understand the weakness of tipping-bucket rain gauges at high rain rates. Participants will understand how the bright-band effect causes abnormally high radar rainfall estimates.
