Travel and Terrain Advice
- Avoid sunny slopes when the solar radiation is strong, especially if the snow is moist or wet.
- Use caution above cliffs and terrain traps, where small avalanches may have severe consequences.
- Loose wet avalanches may trigger deeper layers resulting in large avalanches.
Avalanche Summary
Small loose wet avalanches were observed on steep south-facing slopes on Thursday.
Snowpack Summary
Warm air temperatures and clear skies have caused melting of the surface snow on south-facing slopes. Crusts may form overnight but should melt quickly in the mornings. The warm weather has settled the snowpack and may be improving the bond to the 30-50 cm deep rain crust from late November, but there are still limited observations of this layer. Lingering wind slabs may exist at higher elevations but are trending towards being unreactive. Cornices may be weakening with the warm air temperatures.
Weather Forecast
SATURDAY: Sunny with cloudy periods and valley clouds, light westerly winds, freezing level around 3400 m with below-freezing temperatures in the valleys.
SUNDAY: Partly cloudy and valley clouds, light westerly winds, freezing level around 3000 m with below-freezing temperatures in the valleys.
MONDAY: Mostly sunny and valley clouds, light westerly winds, freezing level around 3400 m with below-freezing temperatures in the valleys.
