Lingering wind slabs may still be reactive on lee features below alpine ridgetops.

Avoid steep, rocky, and wind affected areas where triggering slabs is more likely.

Moderate

Avalanche Summary

A naturally triggered size 1 storm slab avalanche was reported on a southeast aspect in the alpine on Friday.

A few naturally triggered wind slab avalanches up to size 2 were reported on northerly aspects below ridgecrests on Thursday.

If you are getting out into the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network).

Snowpack Summary

Strong solar radiation has created moist snow on sunny aspects at all elevations.

Up to 30 cm of recent snow sits on a thin crust everywhere except north facing aspects at upper elevations where the recent snow remained dry.

Lingering wind slabs may still be reactive on lee features below alpine ridgetops.

A series of crusts exist in the upper snowpack.

Expect difficult travel at lower elevations with thin snow coverage.
