Avalanche Summary

Nothing new today.

Snowpack Summary

Winds have created small isolated windslabs that do not extend far downslope along ridgelines that are overlying a thin melt freeze crust. The snowpack is mainly facetted but generally well settled. Widespread hard windslabs can be found in most open areas at treeline and above. These slabs are stubborn to trigger but if you are in steep thin terrain, you may be able to find a pocket that is reactive.

Weather Summary

Morning low of about -8, with a daytime high of -5. Looks like flurries will carry on throughout the entire day, but amounts will only add up to a few centimeters. Winds will be light from the SW.

The week end will be the start of the cold weather. As the cold air comes in, we are expecting some snow, how much will remain to be seen. Right now up to 14cm, but that could go either way.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.

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.
