Avalanche Summary

No new avalanches were observed or reported on Saturday.

Snowpack Summary

There is 5-15 cm of settled HSt over a well developed temperature crust on all aspects and elevations except north facing terrain above 2600m. There is wide spread wind effect and isolated small wind slabs in the surface snow at alpine elevations.

Weather Summary

A ridge of high pressure over the area will produce generally stable conditions through Monday. Some upslope activity may produce cloudy conditions and trace amounts of snow east of the Divide on Saturday night and Sunday.

On Sunday winds will be light and freezing levels will be near valley bottom. Monday will see a gradual warming trend with freezing levels rising to 2000m.

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.
