Mike,
You don't have sirens over by you do you?
Think the closest ones are in FM.
I subscribe to Code Red Alert, if your municipality participates it's no charge to you,
ECN - EMERGENCY COMMUNICATIONS NETWORK
You can register your house/cell numbers and they call you with weather alerts 24/7.
My phones were ringing off the hook yesterday.
I like it because I still get notified of weather conditions at the house no matter where I am.
We were in Dallas a few weeks ago when some bad stuff came thru so we were able to call home to the baby sitter and give her a heads up.
