Although it’s officially still fall, winter weather is making an appearance both north and west of the GTA.

Lake-effect snow was falling in the Barrie and London areas Saturday morning and might also turn up in other areas north of the GTA.

Whiteout conditions were reported in Barrie and Innisfil and on parts of Highway 400.

And Environment Canada has issued a special weather statement for Markham and Vaughan due to possible lake-effect snow on Saturday.

Meteorologist Harold Hosein said cold air across Georgian Bay, along with Saturday’s gusty winds, is to blame.

“If you’re travelling north and northwest of Toronto, watch out for reduced visibilities and several centimetres of fresh snow, making for slippery driving conditions,” Hosein said.

Speaking of winter driving, Michelin Canada’s Sachin Despande says the first step is to get the right tires for the conditions.

“The moment the temperature starts dipping below 7 C, even if it’s bone dry out there and daylight, you need to get your winter tires on,” Despande said.

With December almost here, it’s likely the wintry weather is here to stay.
