The Federal Emergency Management Agency, in coordination with the Federal Communications Commission, announced a nationwide test of the Emergency Alert System and the Wireless Emergency Alerts Wednesday.

The tests will begin around 12:20 p.m. and will go to all consumer cellphones — displaying in English or Spanish depending on the phone’s settings — radios and TVs, according to FEMA’s website.

“The purpose of the Oct. 4 test is to ensure that the systems continue to be effective means of warning the public about emergencies, particularly those on the national level,” the website stated.

The systems are set up to send out Presidential Alerts, Imminent Threat Alerts, Public Safety Alerts, America’s Missing: Broadcast Emergency Response — or AMBER — alerts and Opt-in Test Messages.
