From wind gusts to rain, these graphics show Fiona's power | CBC News

Hundreds of thousands of people in the Maritimes remained without power Sunday following post-tropical storm Fiona, which brought fierce gusts of wind, heavy rain and serious infrastructure damage across Atlantic Canada. .

After surging north from the Caribbean, Fiona came ashore before dawn Saturday as a post-tropical cyclone, battering Nova Scotia, Prince Edward Island, Newfoundland, New Brunswick and Quebec with hurricane-strength winds, heavy rains and huge waves.

As of Sunday morning, more than 256,000 Nova Scotia Power customers and over 82,000 Maritime Electric customers in Prince Edward Island — about 95 per cent of the total — remained in the dark.

More than 415,000 Nova Scotia Power customers — about 80 per cent of the province — had been affected by outages Saturday.

The storm brought nearly 200 millimetres of rain to parts of Nova Scotia and up to 150 mm in parts of New Brunswick, according to Environment Canada.

Fierce winds caused much of the damage brought on by the storm, including downed power lines and trees.

In Nova Scotia, Peter MacKay, a former foreign and defence minister, said he had never seen anything to match Fiona, with winds raging through the night and into the afternoon.

In Newfoundland and Labrador, winds whipped up to 177 km/h in Green Island and 134 km/h in Port aux Basques, a community devastated by Fiona.
