Stevens Pass

On Monday, expect mild temperatures, partly cloudy skies, and generally safe avalanche conditions. Travel will be variable with firm snow surfaces on southerly aspects and shallow coverage below 4000ft. Track where weak snow surfaces exist as a small storm approaches on Tuesday.

Overall, avalanches are unlikely on Monday. 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. While temperatures will warm on Monday with some sun, I don't expect related avalanches. Low elevation and sun-exposed slopes have undergone numerous days of melting in the past week. Keep an eye on the surface of shaded slopes for weak snow, especially above 4,500ft. Observers have reported widespread surface hoar and faceting on the surface. A storm on Tuesday may start with rain and wet these grains at low elevations, but they could persist and get buried later in the week.

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), early-season conditions still exist. Watch for open creeks, rock, buried logs, and small trees. These obstacles can make travel challenging or even cause injury if you run into them.

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.
