Heavy rainfall Tuesday will boomerang back Thursday, says Environment Canada
About 20 millimetres fell on Montreal by Tuesday afternoon, another 10 to 15 millimetres expected overnight
Many parts of southern Quebec remain under special weather warnings due to a system that will continue to bring heavy rain, Environment Canada says.
In some areas of southern Quebec, including the Montreal area, about 20 millimetres of rain fell by Tuesday afternoon, with another 10 to 15 millimetres of rain expected overnight.
The rain will taper off a bit Wednesday, but then another system is moving in on Thursday and Friday which will continue to soak the province. That system is expected to bring another 15 to 25 millimetres of rain.
"It's going to be a grey week, a rainy week, but it won't be raining heavy for all the days of the week," said Environment Canada meteorologist Simon Legault.
The sun is expected to be back on Sunday with a high of 14 C.
Forecast:
- Tonight: Breezy, more rain. Low near 3 C.
- Wednesday: Light rain until about mid-morning, then cloudy skies. High near 7 C.
- Thursday: Cloudy with more rain. High near 6 C.
- Friday: Scattered showers. High near 7 C.
- Saturday: Cloudy with sunny breaks. High near 9 C.
- Sunday: Mostly sunny, mild. High near 14 C.
Possible flooding
Most of southern Quebec could be in for high water levels this week, says Hydro Météo, a non-governmental agency that monitors water levels.
"We recommend people living near the river to be aware of changes and stay away," said Fanny Payette, a meteorologist with the agency.
She said Hydro Météo is particularly concerned about possible overflows of the Châteauguay River, which flows from the Saint Lawrence River down to northern New York, and the Rivière des Anglais which branches off from the Châteauguay just south of Montreal.
The Acadia River, which runs over 82 kilometres from Hemmingford to Carignan in southwestern Quebec, is also at risk of overflowing.
Environment Canada has issued its own warning that flooding is possible during the downpour.
Legault said the problem is that the frozen ground isn't able to absorb all the rain and snow.
