THUNDER BAY -- Environment Canada is warning Thunder Bay residents to bundle up.
The government weather agency states a period of very cold wind chills near -40C is expected Friday morning.
Extreme cold puts everyone at risk.
Watch for cold related symptoms such as shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes.
Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.
Frostbite can develop within minutes on exposed skin, especially with wind chill.
If it's too cold for you to stay outside, it's too cold for your pet to stay outside.
