The test message was originally scheduled for 2:18 p.m. EDT (1818 GMT)on Thursday but is being pushed back to the same time on Oct. 3 because of response efforts to Tropical Depression Florence, the Federal Emergency Management Agency (FEMA) said in a statement. FEMA, which will send the alert, said last week that the messages would bear the headline “Presidential Alert,” and that phones will make a loud tone and have a special vibration. The test has been scheduled to ensure that the alert system would work in the event of a national emergency, and U.S. cellphone users will not be able to opt out.
