The Emergency Alert System (EAS) is a national public warning system that requires radio and TV broadcasters, cable TV, wireless cable systems, satellite and wireline operators to provide the President with capability to address the American people within 10 minutes during a national emergency.
Broadcast, cable, and satellite operators are the stewards of this important public service in close partnership with state, local, tribal, and territorial authorities.
All stations are on the air 24 hours. Check your cable or satellite provider for your channel lineup and station participation. Stations may change after posted on this page without notice to us.
