Power outages, tree damage possible as strong ice storm impacts southern Quebec

"There will likely be transportation delays and cancellations," says ECCC in the warning. "Prolonged utility outages are likely. Significant damage to property, including some buildings and trees, is likely due to the weight of ice."
Significant ice storm, heavy snow expected to impact parts of Quebec mid-week
A prolonged weather event arriving Tuesday night could bring a significant ice storm to parts of Quebec.
A moisture-laden system from the southern U.S. will intensify early Wednesday across southern Quebec.
Freezing rain and ice pellets are expected much of Wednesday for areas including Montreal, Gatineau, and the Eastern Townships. If warmer air pushes north, freezing rain impacts could shift, introducing some uncertainty regarding ice accumulation.
As the system tracks east, heavy snowfall is forecast for central and eastern Quebec, including Gaspé and the Lower North Shore.
Between Wednesday night and Thursday morning, colder air will filter in, transitioning freezing rain and rain in southern Quebec to a mix of wintry precipitation and snow.
Expected totals include 20-40+ cm of snow for the Outaouais, Laurentians, Quebec City, and Gaspé, 20-30+ mm of rain for the Eastern Townships, and 15-30+ mm of freezing rain, with over 30 mm possible north of Montreal in North Shore communities.
Not all freezing rain will accrete due to factors like wind and precipitation rates.
The ice storm may result in multi-day power outages, broken tree branches, and slick untreated surfaces. Flight delays and cancellations are likely in Montreal.
