Up to 20 cm of snow expected for parts of Simcoe County, York Region

Snow blows across a road in Innisfil, Ont.

A Yellow Weather Warning is in effect for parts of Simcoe County and York Region as heavy snow moves through the area Sunday.

Snowfall totals of 10 to 20 centimetres are expected to scatter through the day into the night.

Easterly winds gusting 40 to 50 kilometres an hour may cause blowing snow, especially in open areas. Visibility could be reduced at times, warns the national weather agency.

Travel is expected to be challenging for some communities. Roads and sidewalks may become slippery and hard to navigate as snow builds up throughout the day. Drivers are advised to allow extra time when travelling.

This warning applies to Newmarket, Georgina, and Northern York Region, as well as Innisfil, New Tecumseth, and Angus areas.

A Yellow Weather Warning is issued when hazardous weather may cause damage, disruption, or health impacts. These impacts are moderate, localized, and usually short-term.

Environment Canada states that Yellow alerts are the most common.
