Expect a decent freeze Friday night and a clear morning Saturday with freezing levels rising to 2300 m.

Weather Forecast

Decent refreeze forecasted for Friday night with freezing levels to valley bottom and a clearing trend into Saturday morning. For Saturday, expect light winds, freezing levels to climb to 2300m and clouds to increase mid day. The freeze Saturday night is expected not to be as good with freezing levels only dipping to 1700 m and overcast skies.

Snowpack Summary

Recent storm snow has settled quickly. Where this new snow has not melted away it overlays crusts that exist on all aspects below 2300m and high into the alpine on solar aspects. High N aspects still hold dry powder and some wind effect on lee slopes. Crusts are breaking down and reforming almost daily depending on solar input and freezing levels.

Avalanche Summary

No new avalanches observed or reported today.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
