Forecasters are anticipating a historic storm this weekend as up to 200 millimetres of rain is expected to fall on Atlantic Canada and eastern Quebec.

At a news conference Thursday afternoon, Environment Canada meteorologist Bob Robichaud said winds are likely to top those of post-tropical storm Dorian in 2019.

Experts also predict the storm will cause widespread power outages, flooding in coastal and mainland areas and an “all-time” low pressure across the region.

Fiona is expected to reach Nova Scotia waters by Friday night before passing through the eastern mainland part of the province, Cape Breton and Prince Edward Island on Saturday, and on to Quebec’s Lower North Shore and southeastern Labrador early Sunday.

Coastal areas of Nova Scotia and Newfoundland may experience pounding surf, with waves off Nova Scotia expected to build to more than 10 metres, while wave heights could be more than 12 metres in eastern parts of the Gulf of St. Lawrence.
