You see scenes in those disaster movies that they crank out at a surprisingly rapid rate where everyone's phone starts buzzing and that's when you know it's time to get ready for whatever.

Of course, in a real emergency there will be no head's up like the one I'm giving you now.

According to a WKYT/Lexington report, about 225 million devices will "go off" Wednesday afternoon as the Federal Emergency Management Agency conducts and emergency alert test.

I've been in large groups of people when severe weather alerts or Amber alerts are issued. Man, that is a humbling experience. Your immediate thought is, "Well, this is it."

At 1:18 Central Time Wednesday afternoon, you'll hear the alert and then see "Presidential Alert" followed by "THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed."

Now, seriously, aren't you glad you know that now. Imagine if you didn't and you and your friends' phones go berserk and you see "Presidential alert."

"Cold sweat" would be an understatement.

It's FEMA's first test of the national wireless emergency system. There will be a TV test two minutes later.

These types of alerts, were they real, would only occur in the event of a nationwide emergency.
