Snow squalls could bring "near-zero" visibility to much of southern Ontario this weekend.

Environment and Climate Change Canada has issued snow squall warnings and special weather advisories for almost all of southern Ontario.

The snow squall warnings have been issued for the areas in and around Barrie, Owen Sound, Tobermory and Point Clark, Ont.

“Scattered snow squalls this afternoon will intensify and become more widespread this evening and continue through Sunday morning,” the federal agency said. “Strong gusty winds will also lead to widespread blowing snow.”

Much of the rest of southern Ontario – from London to Ottawa to North Bay, Ont. – are under special weather advisories.

In Toronto, light snow with wind gusts of up to 44 km/h is forecast for Saturday afternoon. Flurries are expected to continue into Sunday night in the city.

“Scattered bands of heavy snow have developed across the area late this morning,” the advisory issued for the Toronto-area reads. “Snow combined with strong gusty winds will lead to visibilities suddenly reduced to near zero at times.”
