The National Oceanic and Atmospheric Administration’s Weather Radio is a 24-hour-a-day broadcast of weather conditions throughout the United States (about 90 percent of the lower 48 states are covered), including its territories. Working in conjunction with the Emergency Alert System and the Federal Communications Commission, as well as other federal, state, and local officials, Weather Radio also broadcasts warnings about other hazards, such as earthquakes and tsunamis, or environmental accidents (oil or chemical spills, for example), and public service announcements like AMBER Alerts about missing children.
