The National Weather Service (NWS)(once known as the National Weather Bureau) is one of the six scientific agencies that make up the National Oceanic an Atmospheric Administration (NOAA) of the United States government. It is tasked with providing "weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy." This is done through a collection of national and regional centers, and more than 122 local weather forecast offices (WFOs). Since the NWS is a government agency, most of its products are in the public domain and available free of charge.
