    Forecast light snowfall and strong southwest winds will create fresh wind slabs. Watch for triggering behind ridgecrests and in gullies.

    A mixed bag of weak interfaces is buried about 15-30 cm down. The nature of these weaknesses varies greatly from valley to valley.

Snowpack Summary

The snow surface is a combination of wind slab at higher elevations, settled storm snow and spotty surface hoar in more sheltered terrain, and a crust on previously sun-exposed slopes. A variable interface buried on Jan 23 is down about 15-35cm. In most locations it appears to be well bonded; however, buried surface hoar (up to 20mm) has been found in some locations. This will be something to watch as the overlying slab develops. The lower snowpack is generally well-settled.
