Buy a better radio that only alerts for your area. Mine is a Midland
model.

In the "old days" one could mistune a TV set and detect tornadoes.



Tornados create an electrical disturbance somewhere in the 55 megahertz
range, close to the frequency band assigned to channel 2. With this
phenomenon in mind, Newton Weller, an electronics technician, has
devised the following method for using your TV set as a tornado warning
device.

Tune to channel 13 and turn the brightness control down to the point
where the image is nearly--not completely--black. Then turn to channel
2. Lightning will register as horizontal streaks on the screen. When the
picture becomes bright enough to be seen, or when the screen glows with
an even light, there's a tornado within 20 miles, and it's time to find
Toto and head for the basement.
