An Ontario winter storm is sweeping across the province today, with heavy snowfall creating dangerous travel conditions.
While the messy conditions will taper off by the afternoon, it's not the last time we'll see snow this week.
According to TWN, another powerful winter storm is forecasted to arrive by Thursday.
The system could bring another 20 centimetres of snow to southern Ontario this week.
The Niagara Falls area could see 15 centimetres by Friday night with an additional 5 centimetres over the weekend.
Meanwhile, Toronto could see an additional 18 centimetres by Sunday.
Currently, Environment Canada is warning residents to postpone all non-essential travel until the roads are cleared.
