As Canadians gear up for the May long weekend — often seen as the unofficial start to summer — residents in parts of northern Quebec are bracing for a powerful blizzard, with up to 25 cm of snow expected and whiteout conditions making travel nearly impossible.

This rare May snowstorm serves as a dramatic contrast to the heat waves recently experienced in southern parts of the country, reinforcing Canada’s reputation for unpredictable spring weather.
Where the Blizzard Warning Is in Effect
Environment and Climate Change Canada (ECCC) issued the blizzard warning on Friday, May 16, 2025, for the following regions in northern Quebec:
- Kangiqsujuaq – Raglan Lake
- Quaqtaq
The warning comes as a deepening low-pressure system near Hudson Bay clashes with cold Arctic air locked in place over the region, creating ideal conditions for blizzard-level snowfall and intense wind gusts.
What to Expect: Snowfall, Winds, and Travel Hazards
According to ECCC, residents in affected areas can expect:
- Snowfall accumulation of up to 25 cm
- Wind speeds exceeding 40 km/h
- Visibility reduced to less than 400 metres for at least four consecutive hours
“Rapidly accumulating snow will make travel difficult. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow,” the official weather statement warned.
Such conditions meet the criteria for a blizzard, defined by sustained winds of 40 km/h or more, combined with heavy snowfall that significantly reduces visibility for extended periods.
Northern Quebec Hit with Third Blizzard in May
This is the fourth blizzard warning issued in Canada this month and the third for this region of northern Quebec since May 8, 2025. The affected communities, home to more than 1,000 residents collectively, are no strangers to harsh weather — but even by their standards, this is an unusually persistent cold pattern for late spring.
Summer Starts Elsewhere, But Winter Holds On Here
While snow continues to bury parts of northern Quebec, much of southern Canada is seeing the early signs of summer:
- Southern Quebec recently experienced a heat wave.
- Emerson, Manitoba, recorded 37.8°C on May 11, the hottest May temperature ever documented so early in the year in Canada.
The contrast between sweltering southern temperatures and snowy northern conditions underscores Canada’s vast and varied climate zones — a country where blizzards and heat waves can happen at the same time.
Final Thoughts: Prepare for the Unexpected
The May long weekend, also known as Victoria Day weekend, is typically marked by gardening, camping, and outdoor gatherings. But for residents in northern Quebec, snow boots and shovels will replace flip-flops and lawn chairs — at least for now.
Canadians planning travel or outdoor activities this weekend are urged to check local forecasts and alerts, especially in northern regions where blizzard conditions could pose serious safety risks.
