YELLOW WARNING - COLD

Impact Level: Moderate

Forecast Confidence: High

A prolonged period of very cold wind chills is expected. What: Wind chills near minus 30. When: Tonight into Saturday morning. Wind chills near minus 30 may return Saturday night into Sunday 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. 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. Please continue to monitor alerts and forecasts issued by Environment Canada.

Forecast Confidence: High

Poor visibility in snow and blowing snow continues tonight. What: Significantly reduced visibility in blowing snow. Strong wind gusts of 70 to 80 km/h possible.
