According to the Maryland Emergency Management Agency, Marylanders who travel into Washington, D.C., or live close to the District may receive a Wireless Emergency Alert test on their cellphone on Saturday, June 22.

In anticipation of the Independence Day celebrations, the District of Columbia’s Homeland Security and Emergency Management Agency will test the Wireless Emergency Alerts system between 11 and 11:30 a.m. The test will evaluate the District’s ability to send information during an emergency to a targeted geographic area — in this case, the National Mall.

The following message will be pushed to phones in the vicinity of the National Mall: “This is a test of the District of Columbia Wireless Emergency Alert System. No action required.”

A loud noise will accompany the test message. Individuals close to the National Mall may also receive the WEA test message.
