This CRS report discusses the Emergency Alert System (EAS) and All-Hazard Warnings. "The Emergency Alert System (EAS) is built on a structure conceived in the 1950's when over-the-air broadcasting was the best-available technology for widely disseminating emergency alerts. It is one of several federally managed warning systems. The Federal Emergency Management Agency (FEMA) jointly administers EAS with the Federal Communications Commission (FCC), in cooperation with the National Weather Service (NWS), an organization within the National Oceanic and Atmospheric Administration (NOAA). The NOAA/NWS weather radio system has been upgraded to an all-hazard warning capability. Measures to improve the NOAA network and the new Digital Emergency Alert System (DEAS) are ongoing. The Department of Homeland Security (DHS), working with the Association of Public Television Stations, is implementing a program that will disseminate national alert messages over digital broadcast airwaves, using satellite and public TV broadcast towers. This program, referred to as the Integrated Public Alert and Warning System (IPAWS), is part of the Department's response to an Executive Order requiring the Secretary of Homeland Security to meet specific requirements for an alert system as part of U.S. policy."
