WASHINGTON – FEMA, in coordination with the Federal Communications Commission, will conduct a nationwide test of the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) this summer.
The national test will consist of two portions, testing WEA and EAS capabilities. Both tests will begin at 2:20 p.m. ET on Wednesday, Aug. 11.
Oh, I see, it was only on phones and TV.
I DID hear a very scary alert on the car radio. I was nearing when I changed the channel. It was around that time. I came in on it, and they were saying to go your cellar or the lowest place you could immediately! Then all of a sudden it stops and that awful noise comes back on and they are talking about a very severe thunderstorm and possible tornado warning for our county (Mifflin) and several others around it. I was about to get out of the car when the sky went very dark, a huge wind whipped up, bending trees! And hail started banging on the roof of the carport I had just pulled into. Scary! I waited over five minutes for a lull to run the dozen or so yards into the house. The rest of the storm was pretty tame. Maybe the real weather alert interrupted the test?
