WEA is a public safety alerting system allowing government officials to target emergency information to a specific geographic area using individuals’ cell phones or other mobile devices. WEA allows for targeted and efficient messaging, which is critical during emergencies. Periodic testing of public alerts and warning systems helps local governments assess their systems and identify any needed improvements. Conducting a regional test supports the continued use, training, and improvement of the WEA system.
Jurisdictions participating in the test include the cities of Alexandria, Bowie, College Park, Fairfax, Falls Church, Gaithersburg, Greenbelt, Manassas, Manassas Park, Rockville, and Takoma Park; Arlington, Charles, Fairfax, Frederick, Loudoun, Montgomery, Prince George’s, and Prince William counties; and the District of Columbia.
