Atlantic Canadians have been dressing in layers as a blast of arctic air engulfs the region.
On Sunday, temperatures dipped into the -20s, feeling closer to -30 with the windchill.
Officials have been warning residents to limit their time spent outdoors as hypothermia and frostbite can happen in a matter of minutes. Drivers are also encouraged to carry an emergency kit in their cars in case they get stranded in the frigid conditions through the winter months.
Several places will continue to feel the cold temperatures on Monday, including Labrador City, where a windchill warning was issued.
According to Environment Canada, strong winds combined with cold temperatures will continue to give bitterly cold windchill through the morning hours. That prompted some schools in Labrador west to cancel classes Monday.
"Starting Tuesday, the Maritimes will see a significant warm-up," says Monica Vaswani, a meteorologist at The Weather Network. "It will be Thursday or Friday before Newfoundland sees temperatures climb."
