Confidence

Low - Due to the number of field observations

Weather Forecast

SATURDAY: Mix of sun and cloud. Alpine temperatures near -2 and freezing levels 1500 m. Ridgetop wind moderate from the west.

SUNDAY: Mainly sunny. Alpine temperatures near -1 and freezing levels 1700 m. Ridgetop wind light northeast.

MONDAY: Mainly sunny. Alpine temperatures near 1 and freezing levels 2000 m. Ridgetop wind light northeast.

Avalanche Summary

No recent avalanche observations have been reported.

Snowpack Summary

In the alpine, up to 10 cm cold wind-affected snow is holding onto northerly aspects. Southerly winds have produced isolated wind slabs around ridges and in the immediate lee of slopes in the alpine. Cornices have been failing recently.

A crust is found on solar alpine slopes and all aspects below. Warm overnight temperatures are preventing strong crust recovery as you lose elevation. Expect thin surface crusts to break down quickly with daytime warming and rain. Below treeline the snowpack is saturated and rapidly melting.

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.
