Daily melt-freeze cycles. Solar input will quickly shed recent storm snow (5–20 cm) on sun-exposed aspects. Lingering small wind slabs may persist at higher elevations.

Avalanche Summary

No new avalanches were observed or reported on Sunday.

Snowpack Summary

There is 5-10 cm of settled HST over a well-developed crust on all aspects and elevations except north-facing terrain above 2600m. There is widespread wind effect and isolated small wind slabs in the surface snow at alpine elevations.

Weather Summary

Slight warming on Tuesday. Valley temps near 7, ridge around 4. Freezing level rising to ~2100 m. Light west winds. High pressure brings mostly clear skies, with a chance of afternoon convective buildup.

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.
