The first national test of the Emergency Alert System is activated in the United States at 2:00 p.m. EST.

The Emergency Alert System (EAS) is a national warning system in the United States designed to allow authorized officials to broadcast emergency alerts and warning messages to the public via cable, satellite and broadcast television and AM, FM and satellite radio. Informally, Emergency Alert System is sometimes conflated with its mobile phone counterpart Wireless Emergency Alerts (WEA), a different but related system. However, both the EAS and WEA, among other systems, are coordinated under the Integrated Public Alert and Warning System (IPAWS).

November 9 is the 313th day of the year in the Gregorian calendar; 52 days remain until the end of the year.
