Regions

Glacier.

New snow and strong winds have formed a fresh windslab. Wait for the snow to settle and bond before stepping out onto large terrain features.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

The new snow and wind caused a small natural avalanche cycle up to size 2.5 through the highway corridor on Tuesday. A field team was also able to easily trigger several size 1 storm slabs from steep terrain at treeline.

A widespread, natural avalanche cycle occurred up to size 3.5 on Thursday and Friday of last week during the atmospheric river. Explosive avalanche control also produced results up to size 4.

Check out pics from the recent avalanche cycle in the MIN Reports.

Snowpack Summary

In the alpine, 100 - 150cm of recent snow was redistributed by strong winds.

At treeline and below 20cms sits on a thick crust that has moist snow below. Another crust from early March is buried 70-150 cm deep.

The Feb 9 and Jan 26 surface hoar layers are now buried 150-210 cm deep. These layers have become less active with the colder temperatures.

Weather Summary

Expect a mix of sun & cloud as the dregs of the last system flushes out

Tonight Flurries. Snow 1-2cms. Alpine low -13°C. Winds W 35-50km/h. Freezing level (FZL) valley bottom

Thur Flurries. Snow 1-2cms. Alpine high -11°C. Wind W 30-55km/h. FZL 800m

Fri Mix of Sun/cloud/flurries. Snow 1-2cms. Alpine high -6°C. Wind SW 25-35km/h. FZL 1400m

Sat Mix of Sun/cloud/flurries. Snow 1-2cms. Wind SW 15-30km/h. FZL 1600m

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
