continue to assess conditions as you move through terrain. Rider triggerable wind slab could still be found in exposed terrain from southerly winds. When the sun comes out , small wet loose avalanches will become possible.

Avalanche Summary

No new avalanches were reported in the past couple days.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

A thick crust can be found at or near the surface below 1000m. above this elevation up to 45cm overlies another crust formed in late December. Moist snow can likely still be found below these crusts. As the sun comes out Wednesday afternoon the snow surface could become moist on sun exposed slopes.

Treeline snow depths are roughly 150 to 200 cm.

Weather Summary

Tuesday night

Around 5cm of new snow expected. Light to moderate southerly winds and a low of -3 at 1500m.

Wednesday

A mix of sun and cloud with the possibility of light flurries bringing trace amounts of new snow. Moderate to strong easterly winds and freezing levels around 800m.

Thursday

Stormy with 10 to 20cm of new snow at higher elevations. Moderate to strong southeast winds and freezing levels rising to 1600m.

Friday

Stormy with 40 to 70cm of new snow at higher elevations. Strong southeast winds in the morning and light to moderate southwest in the afternoon. Freezing level around 1500m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be alert to conditions that change with elevation and sun exposure.

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.
