The Weather Network – Multi-day blizzard targets parts of eastern Canada, 40 cm of snow possible

Written by

While many Canadians enjoy a respite from stormy weatherthe same cannot be said of those on parts of the east coast.

A powerful low pressure system swirling in the Labrador Sea in the North Atlantic will bring very strong winds along with heavy snow capable of whiteout conditions at times. The biggest areas of impact will be coastal Labrador, where as much as 40 cm of snow accompanied by wind forecast to reach 120 km/h wind gusts.

This multi-day blizzard began Wednesday night and will continue through Friday morning, with perhaps a few short breaks on Thursday.

According to Environment and Climate Change Canada (ECCC), this can make travel “very difficult or impossible due to near zero visibility.” The Met Office is urging people in the affected areas to consider postponing non-essential travel until conditions improve.

However, the wrath of the storm will not remain contained within the great land. Strong wind and snow will affect far eastern Quebec beginning Thursday morning and push eastward Newfoundland throughout the day and until Friday morning.

This storm comes just a few days after the recent “bomb cyclone” (a storm whose barometric pressure drops at least 24 millibars within 24 hours) which brought similar conditions to parts of Atlantic Canada. While this storm doesn’t have the criteria to ‘bomb out’, it will still pack a big punch in some areas.

As with any severe storm, residents are reminded to plan and prepare in advance in case of any power outages, disruptions in ferry traffic or road closures. Property damage is also possible, so it is recommended that loose outdoor objects are secured ahead of this storm.

While western Newfoundland should experience the bulk of the sustained snow and wind, the combination of heavy showers and strong winds will be felt, at least intermittently, across much of the province.

“Prepare for highly variable winter driving conditions until Friday morning,” the ECCC warns in a weather statement.

There are also storm surge warnings for coastal areas of the Gaspe Peninsula Thursday afternoon. There will be a risk of coastal flooding and erosion due to the high water and large waves.
