BARRIE -- Environment Canada has issued a snow squall warning which could see parts of the region getting up to 25 cm of snow by Tuesday morning.

The warning affects Barrie, Collingwood, Hillsdale, Midland, Coldwater, Orr Lake, Orillia, Lagoon City, and Washago.

According to Environment Canada, whiteout conditions are expected throughout the day, with the worst period this afternoon with possible "blizzard-like conditions" being its biggest concern into the evening.

Parts of the region could see five to ten cm during the day and an additional ten to 15 cm this evening.

Environment Canada says snow squalls can reduce visibility to near zero at times, and it asks drivers to consider postponing non-essential travel until the conditions improve.

Provincial police in Dufferin County are already reporting several crashes as a result of the whiteout conditions.

A wind warning is also in effect for the same areas, which could see wind gusts of up to 80km/h throughout the afternoon, diminishing in the evening.
