Stevens Pass

On Sunday, clouds move in with a chance for light precipitation.  While avalanche conditions are generally safe, remember that wind slab avalanches were a concern earlier in the week. Travel will be variable with firm snow surfaces on southerly aspects and shallow coverage below 4000ft.

Overall, avalanches are unlikely on Sunday. If you're traveling to upper elevations or wind-exposed terrain, keep the recent wind slab avalanches in mind. There's still a bit of uncertainty around wind slabs, especially on the east end of the zone. Cooler temperatures and clouds will keep southerly aspects firm. While we don't expect much precipitation, any that falls on Sunday may be rain below about 5,000ft. Keep an eye on the surface of shaded slopes, especially above 5,000ft, for weak snow that could be buried by the next storm. Observers have reported widespread surface hoar and faceting on the surface.

Observers reported avalanches in wind-loaded terrain on Jove Peak and on the eastern edge of the range in the Chiwaukum Mountains as recently as Thursday. Strong east winds drifted snow in open terrain Wednesday, especially at upper elevations. This followed a storm on the 30th which brought 8-10 inches of snow and may have buried surface hoar. While we've found these weak grains in isolated locations, they haven't proven to be a problematic layer.

While the snowpack around the Pass is impressive for the beginning of December (40-60”/105-150cm), plenty of early-season obstacles still exist. Watch for open creeks, buried logs, and numerous small trees that may block your path.

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
