    Thin, old, hard wind slabs may be lurking on lee and cross-loaded alpine terrain, and fresher ones from recent gusty northwesterly winds. Cornices are also large, undermined, and weak, and could be strained by rapid cooling.

Weather Forecast

Increasing cloud cover throughout the day on Wednesday with light snow possible. Continued light snowfall for Thursday and Friday with a trace to 2 cm expected each day. Freezing levels hovering around 1500 m for the forecast period with generally light but gusty southwest through northwesterly winds.

Avalanche Summary

Reports from Monday include a few wet loose sluffs from steep sun-exposed rocky terrain, which was surprisingly little activity considering the high temperatures and solar radiation.

Snowpack Summary

A variable snow surface generally includes light amounts of wind-distributed fresh snow on a supportive crust with surface hoar or surface facets, all breaking down to corn snow on south aspects in the afternoon. But in general the snowpack is strong.

Confidence

Good
