A $20 NOAA weather radio that shrieks outs storm and flash flood warnings would be better. You don't have to monitor it. You only hear it when something wicked this way comes.

Good idea....anything that can be heard and that's distinct.

I have a radio for our winter storms here in Upstate NY.

How about those little horns that women carry for safety. The sound can be a guide, too.
