Weather Forecast

Cloudy skies and calm wind are expected over the next few days. On Friday small amounts of precip are expected. Unexpected bursts of solar energy will have a large impact this time of year.

Snowpack Summary

Wind slabs up to 30cm's have been observed at TL and Alpine locations. The mid pack and base of the snowpack is well settled and well bonded overall. Surface crusts exist below 1900m

Avalanche Summary

No natural avalanches have been reported recently.

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.
