The areas in grey are the areas for which Environment Canada has issued a Special Weather Statement for Wednesday morning into the overnight.

Winter Storm Expected Wednesday Across Newfoundland

Environment and Climate Change Canada has issued a Special Weather Statement for most of Newfoundland as a significant winter storm is set to arrive on Wednesday. This will be a large, messy system capable of producing heavy snow, strong winds, pockets of heavy rain, and areas of reduced visibility.

Who’s Included?

  • St. John’s and vicinity

  • The Avalon Peninsula North

  • The Avalon Peninsula Southeast

  • The Avalon Peninsula Southwest

  • The Burin Peninsula

  • The Bonavista Peninsula

  • Clarenville and vicinity

  • Terra Nova

  • Bonavista North

  • Grander and vicinity

  • Bay of Expolits

  • Grand Falls-Windsor and vicinity

  • Buchans and the Interior

  • Deer Lake - Humber Valley

  • Corner Brook and vicinity

  • Bay St. George

  • Gros Morne

  • Channel-Por aux Basques and vicinity

  • Burgeo - Ramea

  • Connaigre

Timeline

Wednesday morning through overnight Wednesday night.
The storm will move in from southwest to northeast, spreading snow, wind, and for some areas—rain.

What to Expect

Snowfall

  • Widespread 15–30 cm for much of the Island.

  • Local pockets of 30–40 cm possible, though the exact location of the heaviest band remains uncertain.

  • Visibility will drop quickly at times under heavier bursts.

Wind

  • Gusts 80–100 km/h, especially along exposed and coastal areas.

  • Strong northeast to north winds will drive blowing snow—possibly widespread, but confidence on how extensive this becomes depends on temperatures hovering near the freezing mark.

Rain

  • Southeastern Newfoundland, including St. John’s and parts of the Avalon, may see a short period of snow before switching to significant rainfall (30–50 mm).

  • This could lead to minor localized flooding in low-lying or poor-drainage areas.

What Similar Storms Have Caused

  • Very poor driving conditions

  • Travel delays

  • Event cancellations and closures

  • Utility outages

  • Minor wind damage

  • Localized flooding in areas with poor drainage

Forecast Uncertainty

The biggest question mark right now is the rain-snow line and where the heaviest snow sets up. Small track shifts will make a big difference in what falls—and how much. Most of central, western, and northeastern Newfoundland appears likely to stay mainly snow, while the southeast sees more mixing and rain.

Winds are another factor to watch closely. They’ll be strong everywhere, but if temperatures remain just cold enough, blowing snow could become a major issue.

What’s Next

As newer data comes in, we’ll get a clearer idea of:

  • Where the heaviest snow will fall.

  • How much rain southeastern areas will see.

  • How widespread the blowing snow becomes.

I’ll have updated details and a more precise snowfall map as the storm gets closer.

Stay tuned.
