Jim Stefkovich, meteorologist in charge of the Birmingham National Weather Service office, talked about a lot of aspects of weather at the Blount County-Oneonta Chamber breakfast last week. Some of the discussion was esoteric for laypersons, but two main points came through loud and clear. One: know the difference between a severe weather watch and a severe weather warning. The first requires you to pay close attention to possible weather developments for the next 12 hours. The second may require you (and whoever’s with you) to move rapidly to a place of safety within minutes – or less. That’s one point. The second: buy a weather radio – and USE it. Weather sirens are nice, but don’t bet your life on them. Get a weather radio – NOW, if you don’t have one. Emergency management director Max Armstrong seconds the motion.
