Residents throughout much of Southern and Eastern Ontario are expected to face a messy morning commute on Wednesday as a blast of winter weather rolls through beginning on Tuesday night.
Environment Canada has issued snowfall warnings for eastern areas including Kingston, Belleville, Cornwall and also for Ottawa, where as much as 25 centimetres of snow could fall.
The weather agency says a low pressure system southeast of New Orleans is tracking northeast and is expected to intensify into a winter storm.
It says Eastern Ontario will be close enough to the track of the storm to receive a significant snowfall before the system moves into Western Quebec.
A special weather statement has also been issued for the Toronto, Hamilton and Niagara areas, along with Peterborough and Algonquin Park to the east, warning of wet snow associated with the approaching system.
The system is expected to first spread over the southern regions near Lake Erie and Lake Ontario by early Tuesday evening, and the agency says as northerly winds pump in colder air from the Arctic, the precipitation will change to snow by Wednesday morning.
Total snowfall amounts will range from just a couple of centimetres in areas near the shoreline of Lake Ontario in the Toronto to Hamilton areas, to almost 10 centimetres in parts of Niagara and a swath of areas extending east to Algonquin Park.
Airlines have issued travel advisories due to the weather and are recommending passengers check their flight status.
