Highlights

Keep an eye out for conditions that change with elevation and over time.

New snow and southerly winds will continue to build storm slabs over a recently formed melt-freeze crust.

    New snow accompanied by southerly wind will form storm and wind slabs throughout the day.

    At low elevations wet slabs or wet avalanches are possible.

Snowpack Summary

Light to moderate snowfall continues, gradually accumulating above a widespread melt-freeze crust found at all elevations. This snow is being redistributed by southerly winds. Recent warm temperatures have rapidly settled the snow and created moist, heavy surface conditions at lower elevations.

A layer of facets down 40 to 70 formed during the period of arctic air, is reactive in snowpack tests.

The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.

Avalanche Summary

Small wind slabs have been triggered by skiers in the region over the past couple days. These avalanches have run on a crust in the upper snowpack. Check out this MIN.
