West Slopes South

You should find a strong snowpack and generally safe avalanche conditions Monday. Sunshine and warm weather may cause the recent snow to shed from rocks and trees forming very small and inconsequential sluffs. The greatest risk you face may stem difficult and often icy travel conditions.

Observations from around the West-South zone indicate a very strong snowpack in all areas. This should minimize any danger and result in generally safe avalanche conditions. Locations around the region received 1-3” of snow early Sunday morning. You will likely see this snow shed from trees and very steep rocky faces as the sun comes out and temperatures warm. Expect piles of rollerballs and a few very small loose wet avalanches. Due to the minimal amount of snow, we don’t expect these slides to pose any real risk to backcountry travelers. Even though you may see the surface soften during the day, the sun should struggle to fully break down the stout crust. As a result, we anticipate any avalanche activity to remain in the few inches of snow above the most recent crust layer. 

The upper snowpack transformed last week when an atmospheric river brought 3.75-5.75” of water to the zone. Now the upper snowpack consists of several layers of firm crust, refreezing melt-forms, and pockets of rounded grains. Frozen vertical percolation tubes between ice layers can also be found adding a “rebar” like reinforcement to the snow. 

While you may find generally safe avalanche conditions, difficult travel could pose a very real risk. At mid and upper elevations, firm and icy slopes exist. A simple slip may turn into a long and uncontrolled fall. At lower elevations, breakable crusts, frim slopes, frozen tree bombs, and open creeks await you. Make sure you give yourself extra time and bring the tools you need to negotiate these non-avalanche hazards. 

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.
