Flood risk rises on the East Coast with soaking rains this weekend
A soggy long weekend is expected in Atlantic Canada. A slow-moving system is set to bring heavy rainfall and gusty winds to parts of the Maritimes and Newfoundland, elevating the flood threat for some areas
A rough holiday weekend is in store for much of Atlantic Canada as a stagnant pattern brings widespread heavy rainfall to the region.
Some areas could see more than 100 mm of rain through Monday, which could lead to flooding and road washouts in the hardest-hit communities.

Wet, windy weekend on tap for the East Coast
Heavy rainfall gradually spread back toward the west into Saturday, covering New Brunswick, Prince Edward Island, and Nova Scotia. Expect showers to move back into the Halifax area.
Winds will increase Saturday afternoon as the low-pressure system deepens, with 50-80 km/h east-northeasterly gusts possible in exposed, coastal areas.
Rain engulfs much of southern and central Newfoundland by late Saturday afternoon.
We’ll see the rain taper off from west to east across the Maritimes overnight Saturday into early Sunday.
An axis of steady rainfall sits over central and northern Newfoundland by late Sunday afternoon while scattered showers are possible on the Avalon.
Peristent showers will linger on P.E.I., and in north-central Nova Scotia and eastern Cape Breton.
By the end of the rainfall, gauges could pick up 75-100 mm of rain across P.E.I. and Cape Breton, N.S., with even higher totals, locally, possible. Amounts drop sharply farther west across the Maritimes.
Folks in much of Newfoundland may see 30-50 mm of accumulation by the time the rain ends Monday, from west to east.
As a result, a risk for flooding exists for areas that receive the heaviest rainfall adjacent to the Northumberland Strait in New Brunswick, eastern Nova Scotia, and P.E.I. Road washouts are also possible in spots.
Gusty winds and rough surf may lead to some coastal erosion for areas along the Northumberland Strait and Cape Breton.
