Confidence
Fair - Timing or intensity of solar radiation is uncertain
Weather Forecast
Broken cloud is forecast for Monday with the possibility of light rain in the afternoon, particularly in the north of the region. Ridgetop winds are expected to be moderate from the southwest with freezing levels sitting at about 3000m.
Avalanche Summary
Widespread wet snow avalanches to size 2 were reported from the region over the weekend. Large cornice fall at 2400m was also reported releasing a size 2 slab. Continued wet avalanche activity is expected on Monday with forecast high freezing levels.
Snowpack Summary
On Thursday night, light to locally moderate amounts of snow fell forming wind slabs that have settled considerably or turned to wet slabs with warming over the weekend. The recently fallen snow overlies melt-freeze crust sandwiches and wet grains at treeline and in the alpine while warm temperatures continue to penetrate and weaken the isothermal snowpack at lower elevations. The mid-February buried surface hoar layer is down about 140-220 cm. The likelihood of avalanches failing on this layer has been very low due to cooler temperatures, however it may wake up with warming and the consequence continues to be very large destructive avalanches. Cornices in the region are very large and have may become weak with spring temperatures.
