Authorization Basis: The National Weather Service Organic Act of 1890, currently codified as amended in section 313 of title 15 of the federal statutory code (called the United States Code) authorizes the National Weather Service to issue and distribute warnings of environmental hazards. The authority is summarized as: The National Weather Service (NWS) provides 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. NWS data and products form a national information database and infrastructure which can be used by other governmental agencies, the private sector, the public, and the global community. In addition, the National Weather Service supports the Emergency Alert System and provides, in coordination with the Federal Emergency Management Agency, public dissemination of critical pre-event and post-event information of all hazards, including natural disasters and terrorist events. The National Weather Service all-hazards support authority emanates primarily from the National Response Framework as authorized by The Homeland Security Act of 2002, codified predominantly as amended in sections 101 to 557 of title 6 of the United States Code, and The Robert T. Stafford Disaster Relief and Emergency Assistance Act, codified as amended sections 5121 to 5206 of title 42 of the United States Code.
