Quebec Floods: Weekend Rain Risks Deluge
2 Aug
Summary
- Southern Quebec faces flood risk this weekend due to lingering moisture.
- Over 50 mm of precipitation is expected by Monday morning.
- Previous heavy rain has saturated the ground, increasing flood danger.

Southern Quebec is under a flood watch this weekend as atmospheric moisture streams in from the south. Heavy showers and thunderstorms are anticipated through Sunday, with the potential for torrential rainfall and localized flooding. Some communities may experience 50-75 mm of rain by Monday morning, while areas further northwest could see 75-100+ mm.
This persistent wet pattern follows recent heavy rainfall that has already saturated the ground, limiting its capacity to absorb additional precipitation. The risk of urban flash flooding is particularly noted for the Montreal area. Conditions are expected to begin drying out on Monday afternoon as a cold front passes.
