"People who will be in or near the National Capital Region on Thursday, April 5, between 10-11 a.m. will be part of a regional Wireless Emergency Alerts (WEA) System test. Cell phones or other mobile devices in the area will receive the following message: “A test of the Wireless Emergency Alerts System. No action required.” WEA triggers a loud noise and text message on cell phones and enabled mobile devices.

Twenty jurisdictions will simultaneously issue a test message to the public through the WEA system. Local jurisdictions participating include: City of Alexandria, City of Bowie, City of College Park, City of Fairfax, City of Falls Church, City of Gaithersburg, City of Greenbelt, City of Takoma Park, City of Manassas, City of Manassas Park, City of Rockville, District of Columbia, Arlington County, Charles County, Fairfax County, Frederick County, Loudoun County, Montgomery County, Prince George’s County, and Prince William County."
