People across the U.S. will receive a test emergency alert message on their cellphones Wednesday morning.
Most cellphone holders will receive the messages at 11:18 a.m. PST. The messages will say, “This is a test of the National Wireless Emergency Alert System. No action is needed,” with a header saying “Presidential Alert.”
Two minutes after the phone messages, another message will be sent via radio and TV.
The phone messages are part of the first-ever nationwide test of the Wireless Emergency Alerts system. The system is meant to warn about dangerous weather, missing children and other critical situations. Certain wireless providers also allow customers to receive localized alerts of imminent safety threats.
