• Environment Canada has now issued a snowfall warning for Montreal as an incoming winter storm threatens to dump up to 20 cm on the island.
  • Neighbouring regions are looking at a winter storm warning with the potential for 45 cm of snow.
  • Take a look at the projected trajectory of the low-pressure system here.

Environment Canada forecasts that the winter storm coming for Montreal could bring up to 20 cm of snow, as well as up to 45 cm in surrounding regions like Mauricie, Lachute, and Saint-Jérôme. A snowfall warning was issued early Wednesday morning for Metro Montreal, which was followed by a winter storm warning in neighbouring regions in Southern Quebec. In addition to the snow during the day, a rain/snow combo is expected overnight which is sure to make the Thursday morning commute less than desirable. 

Environment Canada warns that travelling conditions are likely to be poor with "low visibility due to rapidly accumulating snow" on the roads, particularly on Thursday morning.

Commuters should "prepare for quickly changing and deteriorating travel conditions" and be ready for a "significant impact on rush hour traffic in urban areas."

Outside of Montreal, drivers are being told to "consider postponing non-essential travel until conditions improve."

Hopefully, drivers will heed this warning, as the last two big storms to hit Montreal in the past couple weeks both ended in massive pile-ups on Quebec highways with countless injuries and, sadly, even a handful of fatalities.

Below you can see the projected trajectory of the low-pressure system that is expected to travel up from the United States into Southern Quebec before heading to Canada's east coast.

Based on the radar prediction above, it looks like Montreal will mostly be facing snow mixed with rain and will hopefully miss out on most of the freezing rain and ice pellets that appear to target regions north of the St. Lawrence.

As you can see in the map below, several regions in Southern Quebec have now been issued either a snowfall or winter storm warning.

The winter storm warning for Mauricie, Lachute, and Saint-Jérôme notes that this incoming low-pressure system "will bring heavy snow to these regions, with more than 35 to 45 cm over some areas."

Environment Canada has been warning people in Quebec that this storm was en route since this past Sunday, with predicted snow totals only climbing in the time since.
