Avalanche Summary

No new avalanches observed.

Snowpack Summary

Generally about 15cm of recent snow overlying the March 19 interface with isolated wind effect. Carefully evaluate the bond with the new snow and the March 19th crust on the solar aspects where the bond is the most susceptible to fast sluffing. This is Spring, so conditions and weather forecasts are all over the map. Be prepared for fast changing conditions with snowfall amounts, wind and solar radiation. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Closely monitor how the new snow is bonding to the crust.

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.
