Environment Canada says the bone-chilling cold sweeping across Canada today will arrive in the Atlantic region early Saturday.
Residents of central and western Labrador will get the worst of it, with the wind making it feel like -50 C overnight and during the early morning hours — and no relief in sight until Wednesday.
Across New Brunswick, the icy winds will make it feel like -30 C, though it will feel colder in the northwestern corner of the province, where the wind will make temperatures feel like -37 C on Saturday and Sunday.

Nova Scotia is expected to get as much as 20 centimetres of snow on Monday.
In Western and Central Canada, orange weather alerts have been issued for all of Saskatchewan and Manitoba, as well as northwestern Ontario, where the extreme cold is likely to cause significant disruptions.
Residents in those areas can expect the wind chill index to reach between -45 C and -50 C, ahead of a slow warming trend this weekend.
“Extreme cold puts everyone at risk,” the federal weather agency says, adding that those outdoor face an elevated risk of frostbite and hypothermia. “Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.”
