Heavy rainfall warning in effect for southern Quebec. Rainfall totals may exceed to 100mm.

The first wave of precipitation has delivered major flooding to parts of the Montreal region Friday morning. Nearly 65mm of rain fell from the remains of hurricane Debby, flooding much of the same area affected by Beryl last month.

Sections of Highway 40, including ramps and service roads were closed at Highway 13 and Cote-Vertu. The result was traffic chaos during the morning commute. If you can work from home today do so. More rain is on the way this afternoon, and totals should easily surpass the all-time August record for the city 85.3mm, set on August 29, 1893.

Several homes and businesses have also been flooded this morning. There are sections of road closed, including Highway 40. 

Waves of tropical moisture will drop heavy rain across the city, with more flash flooding possible.
