Weather Forecast

Tonight and Sunday:  A weak disturbance is forecasted to bring partly cloudy skies, a possibility of a trace of precipitation with light NE winds, surface freezing levels and alpine temperatures around -10 C.Monday: A ridge is keeping the region dry and cold. Expect moderate NE winds, partly cloudy skies and surface freezing levels. Tuesday: The ridge is gaining strength bringing even more dry and cold temperatures.

Avalanche Summary

Skier triggered size 1 slab avalanches were reported yesterday in steep lee features in the Northern part of the region. No new natural avalanches were reported.

Snowpack Summary

5-10 cm of light dry snow now sits above a solid melt-freeze crust at all elevations and all aspects except some very sheltered North aspects. The thin layer of light dry snow is also sitting on a buried the surface hoar layer in isolated areas, but at this time, there is not enough snow above this weak layer to create an avalanche danger. The deep persistent layer of weak facets continues to be a concern in shallow snowpack areas, however the re-frozen upper snowpack may make triggering less likely.

Avalanche Problems

Deep Persistent Slabs

Avoid convexities or areas with a thin, rocky or variable snowpack.>Be aware of the potential for large, deep avalanches.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 3 - 6
