FEMA delays test of presidential alert system until October 3

(WVLT) -- FEMA tweeted on Monday that the test of the presidential alert system will be postponed to October 3, 2018 at 2:18 p.m. Eastern Standard Time.

The delay comes because of severe weather across most of the east coast and ongoing response efforts, according to FEMA.

The wireless emergency alert system sends a message to your phone through a mobile carrier, FEMA says. The messages are different than text messages.

The system allows President Trump to send messages during a national emergency. According to FEMA, you can opt out of general wireless emergency alerts, but not presidential alerts.
