A national emergency alert will go off today on your phones. Here's what to know
The Federal Emergency Management Agency will be testing its Wireless Emergency Alerts and Emergency Alert System today at 2:20 p.m. The WEA alert will be broadcast across all mobile cell phones across the country, and will sound a tone and vibration "similar to when your phone receives an Amber Alert." Scheduled simultaneously, the EAS portion of the test will last one minute on televisions and radios.
