Winter weather continues to dog much of Southern Quebec, causing blowing snow and poor driving conditions on many roads.

Transports Québec reported some visibility concerns on highways around Montreal and the Outaouais region, where many roads are covered in snow.

Those conditions improved over the course of Sunday.

Environment Canada said parts of Southern Quebec could expect anywhere between 5 to 40 centimetres of snow as a storm worked its way up the Eastern Seabord.

Winter storm warnings were in effect for much of Southern Quebec, including the Quebec City, Drummondville, Beauce, and Gaspé.

Montrealers woke up to heavy snowfall that blanketed roads and sidewalks across the city, which saw an accumulation of close to 10 centimetres.

Some flights at Montreal's Pierre-Elliott-Trudeau International Airport were delayed or cancelled due to the weather. 

In the Quebec City region, winds of up to 90 km/h caused blowing snow and reduced visibility. The high winds also raised concerns for water levels in the St. Lawrence River.

Environment Canada has a coastal flood warning in effect for Quebec City during high tide between 5 p.m. and 9 p.m.
