Regions

Little Yoho.

Overcast skies and light precipitation will reduce solar induced hazards over the next few days. Spring time hazard ratings in effect. Although not extraordinarily active, cornice failures remain a concern.

Weather Forecast

Wed: 2-5 cm of snow with light winds and freezing levels around 1500m. Thurs: Clear in the morning with a good freeze. Overcast and light precip during the day with freezing levels rising to 1900m. Fri: Weaker overnight freeze and another 5-10 cm of snow above the 1900m freezing level. Rain at lower elevations. Winds remaining light from the S/SW

Snowpack Summary

The snowpack is well settled with no surface instabilities. A supportive melt-freeze crust exists on all aspects to 1900m and higher on south and west aspects. Dry snow exists on N/NE aspects above this. The deep persistent weak layers are dormant, but may awaken if it warms up. Cornices are large this time of year and tend to fall off on warm days

Avalanche Summary

Small loose snow point release avalanche were observed on south facing terrain in the afternoon.

Confidence

Due to the number and quality of field observations

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
