Regions

Glacier.

Heed caution near ridgetops in the alpine for freshly buried wind slabs. Despite warmer temperatures, this instability will need a couple more days to heal.

Thanks to folks for the up-tick in MIN reports!

Confidence

High

Avalanche Summary

Riders are still finding pockets of reactive wind slab mostly in alpine lee features. Good photos in this Min Report

The field team observed a rider triggering a small slab in a steep unsupported feature on Thursday. The rider was unharmed but was pushed a short ways through rocky terrain

Weather Summary

A weak low pressure system to our south competes with high pressure to our north. The result will be a mix of sun and cloud with some scattered flurries over the next few days.

Overnight: Trace of precip. South wind: 10-20km/hr, Freezing Level(FZL) 600m

Mon: Cloudy with flurries. Snow: trace. Alpine high -7°C. Wind SW 20 km/hr, FZL 1400m

Tues: Snowfall: Trace. Alpine high -8°C, Light west winds, 900m FZL

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Carefully evaluate steep lines for wind slabs.

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.
