New snow is overlying a variety of snow surfaces and creating new windslabs in alpine terrain. Its still a young thin snowpack so ski with caution. Watch for winds increasing on saturday making windslabs more reactive.

Avalanche Summary
Visibility limited any new observations on Friday.
Snowpack Summary
10cm of new snow with warm temps and rapid settlement has fallen over the past 24hrs. This new snow is overlying a variety of snow surface from crust on solar aspects, to facets on more northern aspects and hard wind slabs in many areas. Due to the warmer temps during which this snow fell, this snow should bond to the underlying surface fairly well. The hazards that were evident yesterday are now just buried under the snow surface. Watch for windslabs in alpine terrain especially where the new snow is overlying the weaker surface facets. Telling depths are still fairly low for this time of year with only 50-70cm of snow at treeline.
Weather Summary
Another 5-8cm of snow is possible as the cold front continues to push down across the region. Saturday the snowfall should begin to taper off and temps will be cooler (-12) with winds into the moderate range. Later in the weekend we are expecting another 5-10cm of snow.
More details can be found in the Mountain Weather Forecast.
