Watch temperatures during the day as we are expected to be close to threshold. Sudden intense sun could also be problematic.
Summary
Weather Forecast
Light snow, cloudy conditions, and moderate temperatures are expected to continue until the weekend. This is unlikely to reduce the hazard in the short-term.
Snowpack Summary
60-90 cm of recent storm snow overlies a crust. The recent heavy precipitation, wind and warmer temperatures created storm slabs which continue to stress the January 30th crust interface. Isothermal conditions can be encountered below treeline under a varying crust. Winslabs are common in exposed areas at treeline and in the alpine.
Avalanche Summary
Recent avalanche control produced numerous slab avalanches up to size 3. Many of the avalanches started dry and turned wet at lower elevations. Also there was evidence of a widespread cycle up to size 3.5 throughout the forecast region. Some avalanches were running close to full path.
Confidence
Problems
Storm Slabs
50 to 90 cm of storm snow lays over the Jan 30 crust interface. A weak bond exists on this interface and storm snow avalanches are possible.
- Be aware of the potential for wide propagations.
- Minimize overhead exposure during periods of heavy loading from new snow, wind.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Wind Slabs
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
