Temperatures down to -50C with wind chill facing Yellowknife and the North Slave have also reached Northern parts of the territory, prompting Environment and Climate Change Canada to extend several extreme weather warnings.

Communities in the Beaufort Delta are now under weather warnings, as is the Sahtu. Tłı̨chǫ regions remain under extreme cold warnings. The warning states these regions should expect “prolonged periods of very cold wind chills” overnight into Wednesday and Thursday.

Temperatures without windchill in Yellowknife are forecast at -38C Wednesday, before staying in the -20Cs for the rest of the week.


The federal environment ministry recommends people cover up as frostbite can develop “within minutes,” especially when wind chill is present. “Dress warmly,” the advisory read. “Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.”

Meanwhile, the Fort Liard region, including Nahanni Butte and Sambaa K’e, should expect heavy snowfall until midnight Tuesday, with lighter snow overnight. An estimated 10 centimetres is expected to accumulate by Wednesday morning.

The region experienced heavy snowfall exactly a week ago, with 20 to 25 centimetres forecast December 9.

Anyone traveling in the region may experience reduced visibility, as well as changing and worsening travel conditions.

The weather has eased up slightly for other regions previously under extreme cold warnings, including South Slave communities.
