Avalanche Summary

We haven't received any recent reports of avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

A dusting of snow will fall onto a widespread hard melt-freeze crust that is found everywhere except high-elevation northerly aspects, where soft snow may exist. Small wind slabs may be found on northerly alpine slopes from southwest wind.

Two weak layers that formed in February and March are found in the middle of the snowpack. These layers are currently dormant, but they could be triggered with a large load such as a cornice fall.

Weather Summary

Tuesday Night

Cloudy with 1 to 3 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Wednesday

Mostly cloudy with 0 to 1 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

Thursday

Partly cloudy. 20 to 30 km/h southeast ridgetop wind. Treeline temperature +6 °C. Freezing level 2200 m.

Friday

A mix of sun and cloud. 20 to 40 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
