    East, south and west facing slopes will all become effected by strong solar radiation, resulting in morning crust and wet snow in the afternoon. Watch for wet avalanches in gullies and other steep terrain feature starting mid-day.

Weather Forecast

Cloudy and windier Friday. Saturday's forecast is for moderate precipitation and more wind.  Windslabs can be expected 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

No new avalanches reported.
