A blast of Arctic air has settled over southeastern Manitoba, bringing frigid temperatures that are expected to last well into the second week of February.
Meteorologist Natalie Hasell from Environment and Climate Change Canada says the cold snap is a result of an Arctic air mass moving in behind a passing low-pressure system.
"Calmer weather, perhaps, but really difficult weather. Especially for those who are more susceptible."
Tuesday's high is around -18. The wind chill of -25 means there is a risk of frostbite.
Hasell warns that prolonged exposure to extreme cold can be dangerous for everyone, but especially for vulnerable groups such as infants, seniors, people with chronic illnesses and those who work outdoors. The extreme cold can also pose a risk to pets and livestock.
"It's too cold for your pets, so definitely a thing to consider," she says regarding sweaters and boots when taking dogs outside. "People who have livestock—I'm not quite sure what the options are, but certainly worth preparing something for them."
Hasell notes that anyone with cardiovascular conditions should take extra care when heading outside, especially after recent snowfall.
"The cold is stressful, and especially cold following snow, because everyone's going to shovel," she says. "So, if that's your job, do it slowly, in bits at a time. Take breaks. Make sure to rest."
With temperatures expected to remain well below seasonal averages, frostbite and hypothermia become real concerns. Hasell says that in extreme conditions, frostbite can develop quickly on exposed skin.
"There's sometimes where the pain of frostbite has already switched over to numbness," she says. "Well, that numbness is frostbite, because the stuff under your skin is getting frozen, including your nerves."
She advises anyone venturing outside to dress in layers, cover up exposed skin and limit time outdoors when possible. Wind chill values in the region could bring conditions where exposed skin can freeze in as little as 10 minutes.
For those who must travel, Hasell urges preparation. She recommends checking routes ahead of time, dressing appropriately, carrying an emergency kit and ensuring vehicles are in good condition before heading out.
"If you are driving and you are stuck on the highway—be it in snow and blowing snow and reduced visibility or in extreme cold—if your car's intact, stay in your car. It is already offering you shelter," she says. "If your car is not intact, stay close to your car as much as you can."
The meteorologist also reminds people to look out for each other during these frigid conditions, particularly newcomers to the province who may not be familiar with Manitoba winters.
"If you know somebody who's new to the area, make sure to touch base with them to make sure that they're prepared for the cold weather," she says.
Despite the deep freeze, Hasell says Manitoba winters are known for temperature fluctuations and that a brief warm-up could still be on the horizon. For now, though, the cold has settled in, and residents are urged to take precautions to stay safe.
