Regions

Long Range Mountains, Corner Brook, Gros Morne, Northern Peninsula.

Watch for changing conditions over the next few days.

Avalanche danger will increase with the arrival of a storm on Monday, avoid avalanche terrain during heavy snowfall.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

Our field team observed a size 1 wind slab avalanche on an east facing alpine feature. This avalanche released naturally on Wednesday. We suspect that more wind slab activity has occurred this week but visibility has been challenging at times.

If you’re heading into the hills please consider filling out a Mountain Information Network report.

Snowpack Summary

Previous storm snow and strong wind has resulted in a variable upper snowpack depending on aspect. On north and east aspects up to 100 cm of dense snow overlies a thick crust from the middle of March. On south and west aspects this crust is on or near the surface. In sheltered features 30 to 40 cm of snow overlies the mid March crust, the snowpack below this layer is well settled and strong.

Looking ahead to early next week we are expecting a significant storm that will ramp up Monday through Tuesday. This storm will bring 25 to 50 cm of snow with strong southwest through west wind, forming deep deposits on north and east aspects.

Weather Summary

Saturday Night
Mostly cloudy. 1 to 2 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -17 °C.

Sunday
Mostly sunny. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -13 °C.

Monday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Tuesday
Mostly cloudy. 20 to 40 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Avoid avalanche terrain during periods of heavy snowfall.
  • Carefully manage your exposure to overhead hazards.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
