Environment Canada has issued a rainfall warning for the Montreal area as Isaias closes in on Quebec.
As of 2:00 p.m. Tuesday, the agency's tropical cyclone information statement also covers the metro area after initially focusing on the province's eastern regions.
The St. Lawrence River valley from Montreal to Quebec City is most likely to be affected with up to 60 mm [of rain].
Given the intensity of the rain and its forecasted short duration, "minor" flooding is possible in some areas.
According to the latest update, "Southeasterly winds gusting to 50 km/h are likely over New Brunswick and parts of Quebec including the Eastern Townships, Quebec City and areas along the St. Lawrence River tonight."
The Gaspé region, meanwhile, "could see gusts up to 70 km/h Wednesday afternoon."
More information is coming from Environment Canada this evening.
