Thousands in N.B. have no power amid extreme cold warnings for parts of the province Outages have an estimated end time between 1 p.m. and 11 p.m. Extreme weather warnings are still in effect for some parts of New Brunswick as nearly 15,000 N.B. Power customers are without power.

After temperatures dropped with wind chills ranging from -33 to -45 Friday night and Saturday morning, some Environment Canada warnings have ended in southern and eastern New Brunswick.

Wind chills currently range from -20 C to -30s with winds gusting between 60 and 80 km/h, according to CBC's Ryan Snoddon.

Strong winds will continue alongside some flurries, creating some whiteout conditions across the Northumberland Shore. An all-time wind chill record was set in Saint John overnight Saturday with a low of -47. The previous record was set on Jan. 18, 1982 at -45.

The risk of frostbite is high and can develop within minutes in areas with wind chills of -28 or below, Environment Canada said in a warning.

"Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes." The outages have an estimated end time between 1 p.m. and 11 p.m.

N.B. Power spokesperson Dominique Couture said in an email to CBC News that the outages were caused by "high winds and tree contact with lines."

"Our crews are currently working safely and efficiently to restore power to impacted customers," said Couture, "Safety is at the heart of everything we do and crews are prepared to work in all types of extreme weather conditions."

Couture said some outages were reported overnight Saturday and new outages continue to be reported Saturday morning.

Thousands of N.S. customers out of power amid strong winds, cold snap Temperatures in Nova Scotia have dropped to -22 C — about -37 with wind chill — as of Saturday morning.

According to Environment Canada, the coldest wind chills could reach -43 in some parts of the province, while maximum wind gusts are forecasted to reach between 70 and 80 kilometres per hour.

The weather agency advises to “cover up.” In its extreme cold warning, it said “frostbite can develop within minutes on exposed skin, especially with wind chill.”

And, “If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.” As strong winds swept through the region overnight, many Nova Scotians were left without electricity. At one point, about 30,000 customers were without power in the province.

Matt Drover, the senior director of transmission and distribution operations at Nova Scotia Power, told Global News the outages are mostly due to the high winds.

“As well, we are having historic temperatures right now… which is leading to situations where electrical equipment isn’t operating due to those cold temperatures.”

Halifax recorded record-breaking wind chill overnight on Saturday. At about 4 a.m., Environment Canada recorded wind chill of -43 at the Halifax Stanfield International Airport, beating the previous 1967 record of -41.

Drover said as temperatures are starting to slowly climb throughout Saturday, which should help with power and restoration equipment. “Out crews are still able to restore power in these cold temperatures,” Drover said, adding there were about 300 crewmembers in the field.

“As winds start to slow down, we’ll be able to restore power more quickly,” he said. He said the utility expect to restore power to the majority of its customers by Saturday night.

“We understand how impactful these outages are when temperatures are this cold… We really appreciate people’s patience,” Drover said.

According to the Nova Scotia Power outage map, about 13,000 customers remain without power as of 1:30 p.m. Saturday.
