Light snow Sunday will help refresh skiing. Expect cool and snowy conditions in the alpine. At lower elevations, expect a weak freeze (or none if it rains) in the AM which may break down through the afternoon—watch for changing conditions.

Confidence

Low

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches were observed or recorded on Saturday.

Snowpack Summary

Sun/temperature crusts exist on all aspects to 2300 m, and to ridge tops on solar aspects. These crusts will break down quickly with daytime heating and high freezing levels. True north aspects hold dry, settled snow above 2300 m. The January 24 persistent weak layer (facets over crust) is down 70–160+ cm and has been unreactive this week. Below this, the snowpack is generally strong with no significant weaknesses.

Weather Summary

Sunday: Trace–10 cm (and possibly rain) with possible upslope (more to the East). Expect light winds, and freezing levels rising from valley bottom to ~2100m by afternoon. Minimal solar input.

Monday: Slightly cooler overnight with freezing levels to 2000m, light winds and mainly cloudy with sunny breaks.

Tuesday: Light snow, increasing winds, but decreasing temperatures to keep things cool.

Terrain and Travel Advice

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.

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.
