|A strengthening coastal storm will impact southern and eastern Quebec this week. (AccuWeather)|
What is not clear at this time, is how much snow will fall. As is often the case with coastal storms, a difference in the storm track of less than 100km can mean 30cm of snow or just flurries here in Montreal. At this time, guidance suggests 10-15cm for Montreal, with less snow north of the city and over 30cm as you move south into the Townships, Vermont and New York. Travel will be impacted, not just here in Montreal, but also up and down the northeast US coast. A winter storm watch is in effect for Vermont and New York. Watches or warnings may be posted for portions of Quebec by Monday. Along the coast, blizzard conditions are forecast in New York City and Boston, along with very strong winds and potential coastal flooding.
This is a rapidly changing weather situation. I will post further updates on Monday.
