    Continued solar radiation may increase the likelihood of a cornice failure or loose wet avalanches on sun-exposed slopes. Be alert to conditions that change throughout the day.

Weather Forecast

Expect mainly sunny skies for Monday and Tuesday as the current ridge of high pressure remains parked over the region. By Tuesday evening, the ridge is expected to "flatten-out" allowing for a Pacific moisture stream to bring moderate snowfall to the region. Ridge top winds are forecast to be moderate from the west on Monday and Tuesday, switching to strong and southwesterly with Wednesday's system. Freezing levels should hover around 1800m for Monday and Tuesday, and then drop to about 1600m on Wednesday.

Avalanche Summary

No new avalanches have been reported. Forecast sunny skies may increase the likelihood of loose wet avalanches and cornice failures.

Snowpack Summary

Snow surfaces can best be described as variable. Melt-freeze conditions can be found on solar aspects in the alpine, and on all aspects at lower elevations. On high north-facing terrain, you'll likely find stubborn old wind slabs and surface facets. The snowpack is generally strong and well settled. However, large cornices may become weak with daytime warming.
