SO IT’S SEVERE WEATHER AWARENESS WEEK, and Dave Foulk was on the radio here in Knoxville encouraging people to buy one of those automatic-alert weather radios. I’ve had this model for several years. I turned the audible alerts off except for the highest-level (tornado, tsunami, etc.) and it’s worked fine, letting us know when there’s a tornado warning and not bothering us over trivia. No tsunami warnings for Knox County yet, and frankly, we’d all better hope it stays that way . . . .
