Blizzard and Snow Squall Warnings Issued for Ontario; Up to 80 cm of Snow Expected

A blizzard warning has been issued for parts of Grey and Bruce counties due to hazardous lake-effect snow squalls that could deliver up to 80 centimeters of snow, according to Environment Canada.

The agency warned of “the worst blizzard conditions” late Wednesday night and into Thursday morning. Areas under the blizzard warning include Hanover, Dundalk, Southern Grey County, Owen Sound, Blue Mountains, Northern Grey County, Saugeen Shores, Kincardine, Southern Bruce County, Wingham, Blyth, and Northern Huron County.

“Lake-effect snow squalls off Lake Huron are expected to intensify as the night progresses,” Environment Canada said. “Strong westerly winds gusting up to 80 km/h will develop late overnight into Thursday morning, resulting in widespread blowing snow and near-zero visibility.”

Although winds are anticipated to ease by Thursday afternoon, heavy snowfall is projected to continue into Friday.

“Travel conditions will range from difficult to nearly impossible,” the agency cautioned, advising motorists to avoid unnecessary travel.

Snowfall accumulations of 40 to 80 centimeters are forecast by Friday, with peak snowfall rates of 5 to 10 centimeters per hour. Environment Canada noted that localized totals exceeding 80 centimeters are possible if a strong snow squall band lingers over one area.

Surrounding regions, including Barrie and Collingwood, are under snow squall warnings.

Meanwhile, the Greater Toronto Area is not under any weather advisories. Toronto is expected to see a mix of sun and clouds on Thursday, with a chance of morning flurries and a high of -4°C.
