Impact Level: Moderate

Forecast Confidence: High


A period of very cold wind chills is expected.

What:
Wind chills of minus 30 to minus 35.

When:
Tonight into Sunday morning.
Wind chill values of minus 30 will likely return Sunday night into Monday morning.

Extreme cold puts everyone at risk.

Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter.

Watch for cold related symptoms: 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.

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

Check on older family, friends and neighbours.

Keep emergency supplies in your vehicle such as extra blankets and jumper cables.

If it's too cold for you to stay outside, it's too cold for your pet to stay outside.

Watch for colour changes on fingers and toes, pain, numbness, a tingling sensation, or swelling. If present, move indoors and begin warming.

Outdoor workers should take regularly scheduled breaks to warm up.
