Environment Canada has issued a special weather statement for Toronto and the GTA ahead of a system that could dump 5 to 10 centimetres of snow on the region, beginning tonight.

The snow is expected to begin in the late evening hours and persist into the early morning, creating the potential for a messy morning commute.

“Motorists should exercise caution when driving around then Golden Horseshoe as hazardous driving conditions could develop due to accumulating snow and poor driving visibility,” the special weather statement from Environment Canada reads. “The public is advised to monitor future forecasts and warnings as further warnings may be required.”

The anticipated snowfall comes as the city remains under an extreme cold weather alert with the temperature expected to drop to – 18 C overnight.

According to Environment Canada, a snow squall warning may need to be issued if the system remains stationary for longer than expected.
