Parts of eastern Ontario are under a rainfall warning with storms expected to move across the region on Saturday.
Environment Canada issued rainfall warnings on Saturday afternoon for cities northeast of Ottawa, including Bancroft, Renfrew, Petawawa, Pembroke and Barry’s Bay.
Special weather statements are in effect for Ottawa and other parts of eastern Ontario with 40 to 80 millimeters of rain forecasted this weekend. Some areas could receive local amounts of up to 100 mm.
“Showers and thunderstorm have developed and are expected to continue through Sunday. The heaviest rainfall is expected late Sunday morning or afternoon. Locally higher amounts in thunderstorms are possible Sunday afternoon and evening,” Environment Canada said.
“This weather pattern typically brings rapidly changing conditions between sunny skies and heavy downpours. Rainfall warnings may be required and issued on short notice to reflect rapidly changing conditions.”
The agency warns that heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.
The rain is expected to taper off on Monday.
