The remnants of Tropical Storm Isaias, which was over New England on Tuesday afternoon, will bring tens of millimeters of rain to southern Quebec in the evening.
The rain, which started during the day in Montreal, should last until around midnight in the metropolis and its surroundings. Precipitation should fall more abundantly for two to three hours during the evening, before calm quietly during the night, explained Michèle Fleury, meteorologist at Environment Canada.
By 6 p.m., about 25 mm had already fallen south of the metropolis and about 20 on the island of Montreal. However, the total amount was expected to climb to around 50mm by midnight.
“After that, the rain will decrease, with a few scattered showers Wednesday morning,” said Ms. Michel.
The expected scenario is more or less the same for Quebec. Here again, around fifty mm of rain are expected, both in the Capitale-Nationale and in Charlevoix, with a few hours delay in the metropolis.
The remains of the storm will then cross Saguenay-Lac-Saint-Jean to move towards the North Shore and Labrador. From 20 to 30 mm are expected in these regions.
Gusts of up to 70 km / h are also expected in the eastern part of the province as the storm dissipates.
Quebecers will then have several days to enjoy the sun. “From tomorrow, a high pressure will set in which will bring us good weather,” confirmed Michèle Fleury.
All in all, Isaias should have a much smaller impact in Quebec than in the United States, where hundreds of thousands of people have been deprived of electricity, particularly in New Jersey and in New York State.
Casually, the situation changed greatly between the first and the second half of the summer in Quebec, particularly in Montreal. While June was marked by an intense drought and several heatwaves, the beginning of August was done in the rain.
Nearly 40 mm of rain had already fallen on the metropolis as of Tuesday, excluding the precipitation of the day related to Isaias. If all the expected rain fell as expected, the city would therefore have received about 90 mm in four days.
However, the average precipitation for the whole of August in Montreal is 94 mm, noted Ms. Fleury.
Quebec City received 12.5 mm during the first three days of the month and receives an average of 104.2 mm of rain in August.
