Water flowing from the Gatineau River (top) into the Ottawa River (foreground) appears muddier after the heavy rains Friday.
At 4:26 p.m. Friday, Environment Canada's weather watchers issued a severe thunderstorm warning for Ottawa, Pontiac and Upper Gatineau. About 100 millimetres of rain fell over the next several hours. Authorities reported that numerous streets, many of them residential, flooded in Aylmer, Gatineau and Hull.
The Gatineau region appears to have been hardest hit by the storm. Highway 148 in Pontiac was closed in and around Eardley and Masham, with some of the four lanes on the highway near Luskville washed away. Notch Road in Chelsea was also reportedly washed out.
