Downpour in Atlantic Canada leads to flooding, power outages

HALIFAX — Much of Atlantic Canada was pummelled with heavy winds and a downpour on Saturday, swamping some areas with extensive flooding and causing two Newfoundland towns to declare a state of emergency.

Environment Canada said a low-pressure system slowly tracked across the East Coast, drenching the region in heavy rains.

In southern New Brunswick, total rainfall amounts had exceeded 50 millimetres in some areas by Saturday afternoon, with isolated reports of more than 100 millimetres, according to the weather agency.

Forecasters said southwestern Nova Scotia and Newfoundland’s south coast could be hit with up to 50 millimetres of rain.

The weather agency said the frozen ground has a reduced ability to absorb the deluge, which, combined with unseasonably mild conditions in some areas, could lead to substantial snowmelt and runoff.

Two Newfoundland towns declared states of emergency.

The mayor of Corner Brook, N.L., declared a state of emergency on Saturday afternoon due to heavy rainfall and snow melting, infrastructure damage and an “overwhelmed” municipal drainage system.

“We are dealing with a very severe rainfall event,” Jim Parsons said in a statement. “All available personnel are working to try and mitigate further damage. For the time being, we ask residents to stay off the streets in affected areas, if possible.”

The town of Humber Arm South in Newfoundland’s Bay of Islands posted to Facebook on Saturday evening saying a state of emergency had been declared from Frenchman’s Cove to Halfway Point and a fire backup plan was put in place.

Newfoundland and Labrador Premier Dwight Ball tweeted photos from crews tending to a washed-out stretch of the Trans-Canada Highway, two gaping holes flanking one of the lanes on either side as muddy water rushed underneath.

“Thank you to all of the contractors and crew for the incredible hard work today,” Ball said.

Several routes were closed due to severe flooding, plugged ditches, lost guardrails and asphalt and an “underground hole area.”

Newfoundland and Labrador Hydro tweeted that some communities on the Northern Peninsula were without power because of an outage caused by a landslide near Woody Point, which they estimated would be restored by Saturday evening. The utility said that restoration efforts had been delayed due to high winds and road closures.

More than 20,000 Maritimers were without power on Saturday morning. By about 7 p.m., Nova Scotia Power said electricity to nearly 1,800 customers had been affected by outages, and New Brunswick’s power utility said about 5,300 people were in the dark.

Greg MacCallum of the New Brunswick Emergency Measures Organization told reporters on Saturday afternoon the rains have caused localized flooding and damaged roads as well as the roofing of some houses.

Several rivers are at risk of overflowing and were being monitored, MacCallum said, adding that people should be on alert for signs of ice jams.

Town officials in Sussex, N.B., advised residents on a few streets to evacuate their homes due to the risk of flooding, but MacCallum said that by Saturday afternoon it appeared the river had crested and people would likely be able to return home soon.

He said Hoyt, N.B., had seen significant flooding, and boats would be made available to the local fire department in the event people weren’t able to leave.

He said an “extensive” list of roads had been closed in the southern part of the province, and warned drivers to avoid any road covered in water, because there could be sinkholes and washouts.

NB Power spokesman Marc Belliveau told reporters forceful gusts have been the primary cause of the outages, with trees knocking out power lines in some areas.
