Every home should have at least one if not a few portable radios that can be used in the event of a power outage due to severe weather. Of course, there are many different types available — wind up, solar, battery.
At the minimum, you want an emergency radio that will pull in AM/FM signals as well as weather bands.
What I suggest is having one emergency radio in the kitchen or other common area of the home. The idea is to have it out in the open, where you can easily grab it and turn it on if you hear a weather siren or something.
Then, have a second radio stashed in your basement or storm shelter. This way, you’ll always have at least one with you in an emergency.
These radios are very important as they will help keep you informed as the situation develops. Tornadoes in particular can crop up very quickly and learning of their existence and location is critical. You can’t just rely on TV or news broadcasts on your smartphone because there likely will be at least a short delay between when they receive the information and when it gets transmitted out.
You’ll get the information faster from weather spotters who report directly to your local weather service. Minutes, even seconds, count!
