A ridiculous amount of rain is coming to Montreal & there's a weather advisory in effect
Montreal could get about half its average monthly rainfall in just a single day.
According to the advisory, rainfall amounts of 25 to 50 millimetres are expected from Friday through Sunday morning.
After a full work week of sunny weather, high UV, and even a two-day heat wave, Montreal's summer streak is about to get soaked.
Environment Canada issued a special weather statement early Friday morning, warning that a significant amount of rain is expected to fall across the city starting Friday evening, with thunderstorms potentially pushing totals even higher.
According to the advisory, rainfall amounts of 25 to 50 millimetres are expected from Friday through Sunday morning, but some areas could see even more than that depending on thunderstorm activity.
"A weather system will move across Southern Quebec this weekend," the agency said. "This system could produce significant rainfall amounts from Friday to Sunday. The heaviest precipitation is expected from Friday evening to Saturday evening."
If the 50 mm forecast holds, Montreal could get about half its average monthly rainfall in just a single day.
Environment Canada notes the advisory applies to several regions, including Montreal, Montérégie, Outaouais, Laurentians, Lanaudière, the Eastern Townships and more. The agency also warns of water accumulation in low-lying areas, and says some rivers could experience increased flow and water levels.
The good news? Sunday afternoon is looking sunny again, with a mild overnight low of 20 C to wrap up the weekend.
Here's the forecast for Montreal over the next few days:
- Friday, June 27: Cloudy with a high of 26 C, followed by evening showers or thunderstorms and 10 to 20 mm of rain.
- Saturday, June 28: More rain with a high of 23 C and humidex of 30. Showers continue into the evening.
- Sunday, June 29: Finally clearing up with a high of 26 C.
So if you had Saturday patio plans, you might want to swap them for Netflix and takeout — or grab an umbrella and make it an adventure.
