Take note of this warning. A federally-run test will take place for a national examination of emergency alerts on Wednesday, afternoon.

Test messages are sent to all mobiles as well as televisions and radios. It will be possible to hear, andon phones — vibrate.

The Federal Emergency Management Agency and the Federal Communications Commission are conducting the test in preparation for emergency situations. The purpose for the testing is to make sure the emergency message system is functioning smoothly in the event that Americans are in danger due to natural disasters, terrorist attacks or other threats to the safety of the public.

You’re probably familiar with the jolting sound that accompany National Weather Service alerts and AMBER (America’s Missing Broadcast Emergency Response) alerts. Wednesday’s cell phone alerts will be delivered through the same wireless system.

What time is the test taking place?

The test will start at around 10:30 a.m. Alaska time on Wednesday, October. 4.

The test window lasts for 30 minutes, however you’ll only receive the notification at a single time. If an emergency occurs during the testing time the test might be delayed — the test can be scheduled for the next week.

What does the test message appear to be?

For mobiles the message will be:

“THIS is a test for the National Wireless Emergency Alert System. No action is needed.” Phones set to Spanish will display: “ESTA ES UNA PRUEBA del Sistema Nacional de Alerta de Emergencia. No se necesita accion.”

Radio and TV will announce:

“This is an nationwide testing for the Emergency Alert System, issued by the Federal Emergency Management Agency, that covers The United States from 14:20 to 14:50 ET. This is merely testing. The public is not required to take any action. the public.”

What is the reason for the test to be happening?

FEMA is mandated by law to hold national testing of the Integrated Public Alert & Warning System (IPAWS) at minimum each three years. The last national test took place in 2021.
