Snow squalls and potentially dangerous driving conditions could impact motorists in the Greater Toronto Area Tuesday.
A snow squall over Lake Ontario is expected to drift north, affecting areas from Ajax to Port Hope through the afternoon hours.
"This could also mean flurries for the city of Toronto with the potential for whiteout conditions as well," says Mark Robinson, a meteorologist at The Weather Network.
According to Environment Canada, visibility in some places may be reduced to 250 metres or less in bursts of heavy snow.
"The heaviest snowfall is expected for areas further east as the band of precipitation sneaks on shore," says Robinson. "Snow squalls are extremely unpredictable, so you can be driving in sunshine one minute and the next minute you may not be able to see the hood of your car."
As a result, drivers are urged to be prepared for suddenly hazardous conditions and adjust travel plans accordingly.
Later in the week, motorists may be testing their winter driving skills once again.
"An Alberta Clipper moving through could bring a "shovelable" amount of snowfall to the region, including the city of Toronto," says Robinson.
