Environment Canada has issued an extreme cold warning for Perth, Wellington and southern Grey counties, with temperatures expected to drop around -30 C Tuesday night and into early Wednesday morning.
Blowing snow will be a problem for some drivers. Winds could gust up to 60 km/h from the southwest Wednesday and Thursday.
Residents are advised to cover up during the cold weather, as frostbite can develop within minutes on exposed skin, especially with the wind chill.
