About 80% of Nova Scotia without power after Dorian slams Atlantic Canada

More than 400,000Nova Scotia Power customers were left without electricity asDorian sweptthroughthe region.

As of 12:39a.m.,the power utility reported therewere 402,103customers without electricity roughly 80per cent of the province.Most of the outages were caused by high winds that downed treesand heavy rain, something that wasexpected to continue through the night after the storm made landfall shortly after 7 p.m.

Power for most customers is expected to be restored by late Sunday night, but Nova Scotia Power announced at 9:15 p.m. that as winds lowered in Yarmouth, N.S., they were able to put crews back on the road there.

Ralph Goodale, Minister of Public Safety and Emergency Preparedness, tweeted on Saturday afternoonthe Canadian Armed Forces are mobilizing to deploy to assist with recovery after the storm moves through.

About 700 military personnel could deploy to Nova Scotia starting Sunday morning to help clear major arteries in order to restore power, the Department of Defence said in a press release.

Dorian approached Nova Scotia as a Category 2 hurricane, but it is now a post-tropical storm.

What's happening out there

Across the province, strong winds uprootedtrees and pulled down power lines.

A crane on South Park Street a busy roadway in downtown Halifax snapped in several places from the power of the wind.

A roof on a building on nearby Queen Street blew off and landed on several cars.

In the water, some boats have been damaged as large waves push them against the rocky shore.

Flooding in other areas hasdamaged cars.

Safety officials were warning storm watchers they are taking a chance getting close to the shoreline to capture images of Dorian.

Nova Scotia Powersaid crews had been out patrolling the lines, but were called down in most of the province as wind gusts started climbing above 90 km/h.

"If it's unsafe for them to be out there, absolutely," said Andrea Anderson, a spokeswoman for the power utility.

Anderson said extra crews have been called in from New Brunswick, Ontario and Quebec to help with more anticipated outages from the storm.

"We've been watching the storm for a number of days and for a number of days we've been getting ready," Anderson said.

Anderson said there are more than 1,000 personnel staged across Nova Scotia, including linesmen, forestry crew, damage assessors, engineers, supervisors, communications staff and customer care representatives.

The utility said later Saturday that they have also called in extra staff from other provinces to get power back more quickly.

If the power goes out during the storm, power customers can expect a wait if conditions are considered unsafe for service crews.

"As soon as the winds end up in the 90 km/h zonewe don't want them out there," she said. "It's not safe."

Nova Scotia emergency officials advised people not to drive in the storm.

"Safety is the primary concern here, stay off the roads, listen to the public officials and their instructions," said Insp. Dustine Rodier, operational support and communications for RCMP.

Emergency officials in Halifax said flying debris flower pots, umbrellas, patio furniture, kids toys was a big concern with the high winds.

"In Category 1 force winds, those items can become very dangerous ... things are going to go flying pretty quickly in 140-150 kilometre per hour winds," Erica Fleck of Halifax Regional Fire and Emergency said Saturday at noon.

Where to go if you need to leave home

The Halifax municipality issued a voluntary evacuation notice to residents who live in some communities along the shore.

A generic water boil advisory is in effect for people drawing drinking water from surface water sources, like lakes. If residents have questions about this advisory, call 1-800-565-1633.

The Canadian Red Cross opened shelters at noon on Saturdayat the Canadian Games Centre, the Dartmouth East Community Centre, and the St. Margaret's Centre. About 150 people were staying at those centres as the day wore on.

The MacKay and Macdonald bridges closed at 4 p.m.
