Marshall County Emergency Management Director Bill Schwindamann, Jr. would like to remind residents of Marshall County that in the event of a tornado, as was the case last week, that when the tornado siren sounds, it will continue to sound until the threat of severe weather has passed, however there will not be an “all-clear” siren. There was some confusion last week as the sirens continued to sound, that some folks thought that meant the all clear was being given. The sirens will go off whenever the National Weather Service issues a tornado warning or if a trained weather spotter visually confirms a funnel cloud. The sirens may also be sounded in the event of large hail or very strong winds of 60 mph or more. If the tornado sirens sound off several times in a row, that means life threatening danger exists and you need to remain in your shelters. The sirens are designed for outdoor warnings because they can’t always be heard when you’re in your house where having the air conditioner on or other noises make it difficult to hear them. Schwindamann says you need to rely on your radio, television, weather radio, or cell phone for warnings when you’re inside your home.
