A significant late-winter snowstorm is poised to blanket parts of Quebec and Atlantic Canada shortly after the official commencement of spring. The first snowflakes are expected to make an appearance on Sunday, with the forecast indicating nearly 10 centimetres of snow in sections of the Greater Montreal Area, Montérégie, Drummondville, and Estrie.
A Wintry Welcome to Spring
Environment Canada has warned residents in these areas to prepare for snowfall rates that may reach up to two centimetres per hour at times. The weather system, which is set to impact Nova Scotia, will begin late Sunday afternoon, with predictions of 10 to 15 centimetres accumulating from the southwestern shore around Digby to Halifax counties. The Halifax Regional Municipality is expected to feel the effects by Sunday evening.
Snowfall is anticipated to intensify through Sunday night into Monday morning, with Environment Canada indicating the potential for heavier precipitation as the system progresses. The snow is forecasted to be particularly wet and heavy, given that temperatures will linger around the freezing mark.
Impact on Nova Scotia and Newfoundland
Residents of northern Nova Scotia can expect the snow to start early on Monday, with Cape Breton likely to see precipitation by mid-morning. The snowfall is projected to continue into Tuesday, with some areas experiencing a mix of snow and ice pellets on Monday evening, although the exact locations remain uncertain.
Meanwhile, Newfoundland faces the likelihood of even more significant snowfall on Monday, with yellow winter storm watches issued for the island’s southern, central, and northeastern regions, and orange winter storm watches for much of eastern Newfoundland. The majority of the island could see between 20 to 30 centimetres of snow, accompanied by northerly wind gusts of up to 100 km/h starting Monday night.
Caution Advised for Road Users
Visibility on the roads is a major concern, with expectations that conditions could deteriorate to near-zero visibility at times. Eastern Newfoundland is forecasted to receive between 30 to 50 centimetres of snow, starting Monday evening and continuing until Tuesday night. Wind gusts on Tuesday may reach 60 km/h, escalating to between 80 to 100 km/h overnight.
As temperatures begin to rise above zero, Environment Canada warns that the snow is likely to transition to ice pellets and freezing rain, further complicating travel conditions. A second period of reduced visibility is anticipated on Tuesday night due to blowing snow, as temperatures are expected to drop again.
Why it Matters
The impending snowstorm serves as a stark reminder of the unpredictable weather patterns that can accompany seasonal transitions in Canada. As communities brace for significant snowfall and potential travel disruptions, the storm underscores the importance of preparation and awareness during such unpredictable weather events. The impact on daily life, travel, and infrastructure could be profound, highlighting the need for residents to stay informed and vigilant.
