Regions

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

As the weekend ends, rising temperatures and heavy precipitation will rapidly increase avalanche danger.

When the danger rating is High, avoid all avalanche terrain.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to the timing of the incoming weather system.

Avalanche Summary

On Friday near bakers brook in Gros Morne park, a large (size 1.5 to 2) slab avalanche was observed and reported to be between 24 and 48 hours old. This avalanche was on an east aspect and was triggered from rapid wind loading.

Looking forward through the weekend, we think that human and naturally triggered avalanches will become more likely with each storm.

If you are getting out in the hills this weekend, consider sharing a couple photos and a few words on a MIN post.

Snowpack Summary

New snowfall combined with moderate west and north winds, will begin to load east through to south aspect terrain. Expect to find new and reactive wind slabs forming over the weekend.

Beginning late Sunday a forecast storm will bring warm weather including snow and rain. Expect the snowpack to react drastically with the upper snowpack becoming unconsolidated and an avalanche cycle to begin.

60-80 cm deep, there is a thick and strong crust that formed in mid-March. In some places, this crust has a thin layer of weak sugary crystals on top. Generally this snow is well stuck to the crust, and it is not an avalanche problem.

Use caution in hot bog areas where weak new snow bridges may hide hollowed out creek holes.

Weather Summary

A major shift in the weather begins late Sunday. Temperatures rapidly rise and heavy precipitation begins, the danger rating will rise quickly.

Friday Night
Cloudy. 5 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

Saturday
Mix of sun and clouds. 1 cm of snow. 40 km/h north ridgetop wind. Treeline temperature -10 °C.

Sunday
Mix of sun and clouds. 2 to 3 cm of snow. 40 km/h northwest ridgetop wind. Treeline temperature -11 °C.

Monday
Mostly cloudy. 30 to 40 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Approach lee and cross-loaded slopes with caution.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
