Environment Canada has issued snowfall warning for much of Southern Ontario, with total amounts of 15 to 25 cm expected.
Two rounds of snow are expected by Tuesday morning across portions of southern Ontario.
The first one is expected Monday with 5 cm of snow possible.
The snow may become light during the afternoon, however another round of heavier snow will move in this evening and persist into Tuesday morning. An additional 15 to 20 cm is likely.
Environment Canada is advising people to prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
