An extreme cold warning is in place for part of northeastern Manitoba.

The alert comes as a period of very cold wind chills is expected in the province's Churchill and York regions, Environment Canada said in an alert early Tuesday morning.

Temperatures there are anticipated to drop into the low minus 30s, with the frigid conditions being caused by what the weather agency describes as "a bitterly cold air mass." When combined with northwesterly winds of 10 to 15 km/h, those cold temperatures are expected to bring extreme wind chills near -50 to Churchill and the Hudson Bay coast Tuesday morning, the alert said.

Those extreme wind chill values are expected to end later Tuesday morning as temperatures slowly moderate.

Environment Canada also issued a reminder that while extreme cold puts everyone at risk, young children, older adults, people with chronic illnesses, people working or exercising outdoors and those without proper shelter face a greater risk in the cold.

It also reminded people that if it's too cold for them to stay outside, it's also too cold for their pets to stay outside.

The alert urged people to cover up and dress in warm layers that can be removed if needed, including an outer wind-resistant layer.

Environment Canada said it issues extreme cold warnings when very cold temperatures or wind chill creates an elevated risk to health, such as frostbite or hypothermia. It noted frostbite can develop within minutes on exposed skin, especially with wind chill.
