Environment Canada is warning of an “impactful winter storm” that’s likely to hit late Tuesday and into Wednesday.

Hazards –15 to 30 cm of snow. Poor visibility in areas of heavy snow and blowing snow. Hazardous travel conditions.

Timing – Tuesday afternoon through Wednesday.

Heavy snowfall and blowing snow associated with a major winter storm are expected to begin affecting Northeastern Ontario Tuesday, with the worst conditions most likely Tuesday night into Wednesday morning. Total snowfall amounts of 15 to 30 cm will be possible.

Northeast winds gusting up to 60 km/h will result in areas of blowing snow giving poor visibility at times.

The exact track of this weather system is still somewhat uncertain, and as a result, expected snowfall amounts may change. Warnings may be issued as this event draws nearer.

Travel is expected to be hazardous due to reduced visibility in some locations. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Poor weather conditions may contribute to transportation delays.
