An extreme cold warning is back for the Cochrane Region.

Environment Canada says wind chill values near or below minus 40 will continue for the rest of the week. The weather agency says you should keep dry, dress warm and cover up any exposed skin. It says frostbite can develop within minutes if skin is exposed.

Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
