Flash floods wreak havoc in Rivière-Rouge
Between 75 and 125 mm of rain fell, causing major flooding on Monday
On Monday, the Rivière-Rouge region in the Laurentians was hit by torrential rains, leading to widespread flooding. Route 117 at Exit 162 was closed due to accumulated water, and several downtown roads were flooded.
In a corridor stretching from Maniwaki to Rivière-Rouge, between 75 and 125 mm of rain fell in less than 24 hours.

A break was also reported on Route 309 at Chemin du Graphite, and a rockfall was reported on the P'tit Train du Nord bike path.
During Monday’s thunderstorms, strong storm cells unleashed significant amounts of rain. The system moved particularly slowly, which contributed to the intensity of the downpour. In fact, a tornado warning was issued late in the afternoon for northeastern Ontario, near Quebec's border.
