After the devastating tornadoes tore through Central Illinois last November, Mclean county officials decided to change how citizens are warned during severe weather.
The new policy allows for sirens to now sound during a severe thunderstorm where winds reach an excess of seventy miles per hour.
These wind speeds are considered "tornado strength."
The director of Mclean County Emergency Management believes it's an important revision to include to help warn residents to be safe.
The first week of March is severe weather awareness week and EMA plans to pass out fliers to notify residents of the new siren policy.
