The National Weather Service, part of the National Oceanic and Atmospheric Administration, provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters, and ocean areas.
The Storm Events Database provides archived severe weather events (e.g., hail, high winds, blizzard) for a specified state, county, and date range. Search results can be further refined to include size, wind speed, property damage, crop damage, number of deaths, and number of injuries depending on the selected event.
Decision Support for Public Safety Officials (OK-First) provides information on training, meetings, workshops, real-time data and support services to safety officials.
