Officials in Laval are keeping a close watch on the Rivière des Milles Îles and the Rivière des Prairies as water levels remain high for both rivers due to heavy rain.
A weather system earlier in the week dumped between 15- and 35 mm of rain over the region, with another 15- to 40 mm expected for Thursday and Friday.
According to Hydro Météo, an agency specializing in hydrology and meteorology research, heavy rain combined with recent snow melt could lead to potential flooding.
