ATCO Electric Yukon says a snapped power line caused an outage stretching from Whistle Bend to Deep Creek and the Alaska Highway North.
(8:51 a.m. update)
ATCO Electric Yukon says power will begin to be restored shortly to about 1,000 customers north of Whitehorse.
Manager Jay Massie says about 2,000 customers were initially without power when a main line snapped near the Mayo Road turnoff about 3:30 a.m. knocking out power to areas such as Whistle Bend, Porter Creek North, and Crestview.
"We have about half of them back on, so 1,000 customers have their lights back on, but folks north of the city are going to be awhile longer as we repair the problem." Massie said.
He says the outage extends as far north as Deep Creek.
Massie says as of 7 a.m. the power should be out for another two hours as crews are slowed by the cold temperatures.
"We do understand it is quite cold, and It's not the ideal time to have the power out for sure." Massie said.
"We are working hard to get it back on, and it's unfortunate we're in this spot."
Temperatures in the Whitehorse area were in the minus 36 degree range, and minus 40 in the outlying areas.
Meantime, two areas of Yukon are under an extreme cold warning from Environment Canada Tuesday morning.
The Kluane Lake region, and Beaver Creek are into the minus 40's temperature-wise, and coupled with a 15 kilometre per hour wind, is giving wind chills near minus 50.
Environment Canada says wind chill values will rise to near minus 40 today as the air temperature rises to approximately minus 35 degrees.
You're advised to dress warmly in layers, and watch for cold related symptoms such as shortness of breath, chest and muscle pain, and numbness in fingers and toes.
Carmacks was actually the cold spot in Canada Tuesday morning with a temperature of minus 45.
