Fairfax County residents, along with the rest of the country, will be getting an emergency alert on their phone a week for today, but it’s just a test.

The Federal Emergency Management Agency will be conducting a nationwide test of the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) at 2:18 p.m. on Wednesday, Oct. 3. The so-called “presidential alert” test, of a system intended for use during national emergencies, was postponed to next week due to the flooding caused by Hurricane Florence.

On social media today, Fairfax County posted a reminded about the wireless alert test and that it shouldn’t be confused with the county’s Fairfax Alerts. Like WEA, Fairfax sends out public safety alerts about severe weather, though the county’s alerts also include traffic alerts and county government closures.
