Avalanche Forecast

High - Forecast snowfall amounts are uncertain

Convective flurries are expected Monday with accumulations of up to 10cm. However, spring storms are difficult to forecast for precipitation amounts, so it is quite possible to receive significantly more, or less, snowfall then predicted. Winds will be light to moderate from the North. The freezing level is expected to be 1500m with Alpine temperatures near -8 °C. By mid-week warmer temperatures are likely with freezing levels as high as 2300m.

A few avalanches were observed today in very steep Alpine terrain. These were generally small in size and consisted of mostly loose dry avalanches or small cornice chunks rolling down steep cliffs. No new slab avalanches were observed or reported today.

Up to 15cm of new snow fell at Treeline in the past 24hrs. This new snow amount varies from valley to valley, and tends to taper to only a few cm's at lower elevations. Wind slabs are present in Alpine terrain, but are more isolated or absent at Treeline elevations. By early in the afternoon the snow was turning moist at lower elevations and despite the cloudy skies, solar aspects received some heat today. As previously reported the mid-pack remains dense and strong, but the basal layers are very weak consisting of anywhere between 50 and 100cm of facets sitting on the ground. Forecasters still have low confidence for traveling in large Alpine terrain, unless there has been widespread previous avalanching.
