With temperatures hovering around the -30 C mark and the wind chill making it feel like -45, Environment Canada has issued extreme cold warnings for nearly all of Alberta.

"As the cold air continues slumping south, temperatures have dropped causing wind chill values to fall below minus 40 this morning. Wind chills will remain near minus 40 through early this week," it reads.

"Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes.

"Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill."

The warning adds that when it's too cold outside for people, it's also too cold outside for pets.
