Rainfall warnings, thunderstorm watches issued across the region
Some parts of western Quebec could get 100 mm of rain by Monday
A rainfall warning has been issued for a wide swath of the Outaouais to the north and west of Gatineau, Que., while thunderstorm watches are in place elsewhere in the region.
Bands of heavy rain will begin falling Sunday night and Monday morning, according to the warning issued by Environment Canada just after 1 p.m. on Sunday.
Accompanying thunderstorms mean that up to 100 millimetres could come down by Monday afternoon in communities like Cantley, Wakefield, Shawville and Maniwaki, Environment Canada said.
The rain could cause flash floods and localized flooding in low-lying areas, Environment Canada said. People should be on the lookout for washouts near rivers, creeks and culverts.
Storm watches in eastern Ontario
Much of the wider Ottawa-Gatineau area, meanwhile, is under a severe thunderstorm watch.
As of 8 p.m. Sunday, that advisory covers an area stretching from Renfrew in the west to Cornwall in the east, and as far south as the Perth area. It also covers the city of Gatineau and parts of the Outaouais to the northeast.
An earlier warning issued for parts of Prescott-Russell has been lifted.
Thunderstorm watches are issued when a severe storm is possible. A warning means one is happening or likely about to happen.
