December 7, 2010 — A powerful system stalled over Quebec on Tuesday, bringing over 20 cm of snow to Montreal.
The first significant snowfall of the season has Montrealers digging out.
Around 25 cm of snow has fallen, making the commute a tedious one. Several residents faced long lineups for trains and buses on Monday evening and throughout the day on Tuesday as strong winds and blowing snow lead to dangerous travel conditions.
Plows have been clearing city streets and sidewalks since Monday, but officials say it could take up to five days to remove all of the snow and get things back to normal.
An unusual weather pattern is what lead to the onset of the stormy conditions. Most systems move from west to east, but this time the snow was coming in from the east towards the west.
“It was the same low that brought heavy rain and strong winds to the Maritimes on Monday,” says Gerald Cheng a meteorologist at The Weather Network. “And because it stalled over Quebec, it continued to bring snow throughout the day on Tuesday.” The heavy snow is tapering, but light flurries are expected to continue on Wednesday.
Strong winds from this system produced high tides in eastern regions including the Gaspe and Quebec's North Shore. Severe damage to coastal homes have been reported. Some basements were flooded with up to 90 mm of water and one regional road was completely washed out.
On Wednesday, Environment Canada admitted that this storm brought more snow than originally forecasted. Here at The Weather Nework, meteorologists say this was a tricky system.
“The models couldn't pick up the intensity of the disturbance, so as a result we got more snow than we were expecting,” says Cheng.
