Continuously assess  conditions as you move through the mountains

Small pockets of wind slab may still remain on high north facing terrain

Confidence

High

Avalanche Summary

No new slab avalanches have been reported in the past 5 days at the time of publishing.

Snowpack Summary

A new crust likely exists on the surface except on high north facing terrain, where up to 20 cm of dense snow overlies a crust from earlier in March. Below this crust is a generally moist upper snowpack.

The mid and lower snowpack contain several crusts that are not concerning.

Weather Summary

Thursday Night

Increasing cloud. 10 to 20 km/h west ridgetop wind. Treeline temperature -1 °C.

Friday

Mostly cloudy with trace amounts of snow in the afternoon. 20 to 40 km/h south ridgetop wind. Treeline temperature -2 °C.

Saturday

Cloudy with 20 to 60 mm of mixed precipitation. 40 to 60 km/h south ridgetop wind. Treeline temperature -1 °C.

Sunday

Cloudy with up to 70 mm of mixed precipitation. 40 to 70 km/h southeast ridgetop wind. Treeline temperature -1 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
