Watch for daytime heating, especially adjacent to rocky areas. Expect new windslabs to develop in the alpine Friday and Saturday.

Weather Forecast

windier and cloudier conditions are forecast for Friday. Snow and SW winds are forecast for Saturday. Expect windslabs to develop in the alpine.

Snowpack Summary

On north aspects, 15-20 of loose facets overlies strong melt-freeze crusts up to 2300m. All other aspects have sun crust in the morning and moist snow in the afternoon, also overlying a strong melt-freeze crust just below the surface. This buried crust provides a bridge over the facets which continue to remain dormant at the base of the snowpack.

Avalanche Summary

Some small loose wet avalanches from steep rocky terrain were noted.

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.
