Change to polygon warning system

      The Calhoun County EMA is reminding residents to have a NOAA radio handy as the agency changes to the tornado warning polygon system. {}The EMA in the future will only activate sirens located within the National Weather Service (NWS) tornado warning polygon. {}

      According to an EMA news release, "'Polygon' is the technical term for the outline or box drawn on a map to represent the danger zone or cone path projected for severe storms."

      The Calhoun County EMA suggest these tips for residents who hear the outdoor warning sirens. {}From now on, residents who hear outdoor warning sirens should: {} {} {} Always take the warning seriously - don't waste time trying to look for the tornado. {} {} {} Always assume the threat is real - even though false alarms do occur, every storm for which a tornado warning is issued still has the potential to down trees, damage homes, and cause injuries. {} {} {} Always take immediate action to find safe shelter from the storm - do not delay moving to a safe shelter.

      They also suggest you sign up for Nixle text message alerts by texting CALHOUNEMA to 888777 or visiting{}{}and have access to a TV or battery-powered radio during severe weather.
