Regions

Glacier.

A warming trend is forecast for the next several days. Expect the afternoon avalanche danger to spike higher and higher every day until the end of next week.

Weather Forecast

A gradual warming trend is in the forecast, reaching it's peak late in the week where little to no overnight recovery will be seen.

Sun: Sunny periods, High 3*C, Freezing level (Fzl) 2400m, light S wind

Mon: Cloudy, Low 2*C, High 4*C, Fzl 2700m

Tues: Cloudy. Low 2*C, High 2*C, Fzl 2500m

Snowpack Summary

We have 2 distinct snowpacks.

Below treeline the spring-time melt-freeze snowpack is solid in the morning, and breaks down with daytime warming.

In the Alpine, on N'ly slopes you'll find a more winterlike snowpack with settled dry powder, and variable crusty surfaces on solar aspects.

Cornices are large and looming- give these a wide berth.

Avalanche Summary

Friday, there was a loose wet size 3 from Gunners 3, a South facing highway avalanche path. Several other loose moist avalanches size 1-2 were noted from mainly S-W facing paths.

On Thursday, there was a size 3 cornice failure in the Tractor Shed East highway avalanche path.

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.
