A system moving into northwestern Ontario is expected to bring significant snowfall beginning tonight.
Environment Canada has issued a special weather statement for several areas, including Thunder Bay, Dryden, Kenora and Fort Frances.
Forecasters say total snowfall amounts of 10 to 15 centimetres are possible, with lower amounts expected closer to the Minnesota border. Periods of heavy snow could also reduce visibility.
The snow is expected to begin tonight and continue through Tuesday evening.
Environment Canada says the system is being driven by a Colorado Low, which could shift in track, meaning snowfall amounts may vary depending on how the system develops.
Travel conditions are expected to deteriorate as snow accumulates, with roads and walkways becoming difficult to navigate. Untreated surfaces may become icy and slippery.
