Environment Canada issued a Winter Weather Travel Advisory on Tuesday.
Heavy snowfall will cross the region resulting in poor visibility at times. Residents in Ottawa can expect around 5 centimetres of snow accumulation. While, Smiths Falls and some areas near Perth towards the St. Lawrence River could see amounts in the 5 to 10 centimetre range.
Travel is expected to be hazardous during the heaviest snowfall due to very poor visibility and rapidly accumulating snow on roadways, in particular, along Highway 401.
