Environment Canada has issued a snow squall watch for parts of central Ontario.
The agency says flurries will develop today and intensify into squalls Wednesday night in the Saugeen Shores, Kincardine, Southern Bruce County, Bruce Peninsula, Sauble Beach and Tobermory areas.
The squalls will develop again Thursday morning and continue into Thursday evening.
Up to 15 centimetres of snow is expected today and a similar amount Thursday.
The agency also warns motorists there could be whiteout conditions at times in blowing snow and bursts of heavy snow.
