(Montreal) The rivers flowing into the St. Lawrence Valley remain under surveillance on Monday as Environment Canada predicts heavy rainfall during the day.

The Charlevoix, Mauricie and Lanaudière regions are subject to a heavy rain warning, issued early Monday morning by Environment Canada.

It is expected that an additional 10 to 15 millimeters of rain could fall within the next 24 hours.

“Heavy rains can cause flash flooding and water accumulation on the roads. Flooding is possible in places in the lowlands.

Earlier Monday morning, the regions of Montérégie, Estrie, Centre-du-Québec and the National Capital were also covered by the heavy rain warning. By mid-morning, this alert had been revoked.

On the flood monitoring site of the Ministry of Public Security, there are average floods in certain waterways and bodies, including the Ouareau River, the North River, the Ottawa River and Lake Maskinongé.

More than fifteen other waterways are considered to be in minor flooding and a dozen others are under close surveillance.

Environment Canada expects the sun to return mid-week.
