Regions

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

Stick to sheltered clearings and meadows where you will find the softest snow, the lowest avalanche danger, and lighter winds.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported, but observations in the windiest parts of the hills have been minimal.

We expect that human triggered avalanches will be likely in wind loaded terrain.

If you are getting out in the hills this weekend, consider making a post on the MIN (Mountain Information Network). You can share riding conditions, snowpack observations, or even just a photo or two.

Snowpack Summary

Sheltered areas may hold up to 140 cm of snow. Before Friday, north and west facing slopes were scoured, and south and east facing slopes may have had up to 300 cm. Generally stormy conditions have prevented high elevation observations, but we suspect that a period of southeast and southwest winds has resulted in varied wind loading and wind scouring across the forecast area.

Fresh, reactive wind slabs will likely continue to form on leeward slopes on Sunday, Monday and Tuesday as the strong winds shift from southwest to northwest.

It continued snowing in the hills even through the warm period on Friday, but you may find a dense or partially frozen layer in the upper snowpack.

Weather Summary

Saturday Night

Cloudy with 3 to 5 cm of snow. Potential for localized heavier snowfall due to streamers off of the Gulf of St Lawrence, 10 cm or more. 40 to 60 km/h southwest ridgetop wind. Alpine temperature -13 °C.

Sunday

Cloudy with 2 to 5 cm of snow. 20 to 40 km/h west ridgetop wind. Alpine temperature -15 °C.

Monday

Mostly cloudy with up to 3 cm of snow. Potential for localized heavier snowsqualls due to streamers off of the Gulf of St Lawrence. 40 to 50 km/h northwest ridgetop wind. Alpine temperature -17 °C.

Tuesday

Mostly cloudy with up to 5 cm of snow. Potential for localized heavier snowsqualls due to streamers off of the Gulf of St Lawrence. 40 to 50 km/h northwest ridgetop wind. Alpine temperature -17 °C.

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be alert to conditions that change with aspect and elevation.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid lee and cross-loaded slopes in the alpine.

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.
