Several parts of southern Ontario are under a snowsquall warning as blast of winter weather moves into the region.

In the Greater Toronto Area, Environment Canada issued the snow squall warning for Newmarket, Georgina, Northern York Region, Uxbridge, Beaverton, and Northern Durham Region.

The agency says snow squalls from Georgian Bay will move into the region this evening and have the potential to cause "rapidly accumulating snowfall."

In these areas, snowfall amounts of five to 10 centimetres can be expected by Tuesday morning.

Meanwhile, north of the Greater Toronto Area could see up to 25 cm of snow by Tuesday morning.

Environment Canada said 15 to 25 cm of snow is possible in Barrie, Collingwood, Hillsdale, Midland, Coldwater, Orr Lake, Orillia, Lagoon City, and Washago.

Hanover, Dundalk, Southern Grey County, Saugeen Shores, Kincardine, and Southern Bruce County could also get 25 cm of snow, Environment Canada says.

A snow squall warning is also in effect for the Lindsay adn Southern Kawartha Lakes area, with five to 10 cm of snow possible Monday night.

Listowel, Milverton, Northern Perth County, Wingham, Blyth, Northern Huron County are forecast to get 10 to 20 cm of snow by Tuesday morning. Environment Canada says areas that see more persistent snow squalls could get up to 30 cm of snow.

Environment Canada says travel will be difficult and motorists are advised to exercise caution.

Strong northwesterly winds will also cause reduced visibilities at times due to blowing snow.

No weather warnings have been issued for Toronto.
