As of this afternoon, Environment Canada has updated its weather statement to a snowfall warning in effect for Newmarket and across York Region, with accumulations of up to 20 centimetres expected Wednesday into Thursday.

Hazards include reduced visibility in heavy snow; rapidly accumulating snow that will make travel difficult; and isolated power outages are possible.

A Texas low tracking northeastward is expected to bring snow to the area early Wednesday afternoon to Thursday morning, with accumulations of 15 cm expected, and locally higher amounts of up to 20 cm likely, the agency advises.

"Be prepared to adjust your driving with changing road conditions. Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow."


Up to 15 centimetres of accumulated snow is possible for Newmarket and York Region beginning Wednesday, according to a special weather statement issued by Environment Canada.

The "significant snowfall" is possible Wednesday afternoon into Thursday morning, with total accumulations of 10 to 15 cm, as a result of a Texas low.

The agency is warning of reduced visibility in heavy snow and rapidly accumulating snow that will make travel difficult.
