A major snowstorm is expected to track across most of southern Ontario starting Sunday (Jan. 16) night.

According to Environment Canada, total snowfall amounts of 15 to 25 cm are possible in the area, with winds gusting up to 60-km/h.

“A low pressure system tracking south of the Great Lakes will bring significant snowfall to the region. Heavy snow will likely significantly impact the Monday morning commute,” reads the warning for Durham and York.

“Local blowing snow is also possible Monday afternoon and evening with gusty northerly to northwesterly winds.”

The rapidly accumulating snow will make travel difficult.

“Visibility may be suddenly reduced at times in heavy snow. There may be a significant impact on rush hour traffic in urban areas,” the warning reads.

“Take frequent breaks and avoid strain when clearing snow.”
