Lo esencial

Avalanches in wind-drifted snow will be possible on Sunday. At lower elevations, especially near the Santiam Pass, wet snow avalanches will be possible due to rain and warm temperatures. Avoid steep terrain where the wind has blown snow onto the slope, or where snow is becoming saturated with rain. Steer clear of gullies, tight trees, and other terrain traps that can make the consequences of an avalanche worse.

    Although we didn't get the snow totals in this storm for widespread wind slab avalanches, we still had moderate to strong wind speeds and plenty of snow available for transport on Saturday. We could get a few more inches of snow overnight and early Sunday before the temperatures warm up, and we move toward a period of high pressure. Continue to watch for signs of wind loading and the rippled snow surface that indicates a wind slab. You can use your ski pole or dig into the upper snowpack to look for a strong-over-weak snowpack structure. If you're unsure about stability, stick to lower angle or wind-sheltered terrain. I would expect this problem to be most likely at upper elevations on north through southeast aspects.

    On Sunday afternoon, temperatures will rise above freezing and mid and lower elevations will see rain on snow. The combined warming and wet precipitation will increase the loose wet avalanche hazard, especially at the Sanitam Pass, where precipitation will be in the form of rain all day, and day-time highs could exceed 40 degrees Fahrenheit. 

    If you're traveling in wet snow and/or rainy conditions, pay attention to how deep your boots sink into the snow. If you sink in past your ankles, it's time to move to lower angle terrain. Remember that wet snow is heavy and can be difficult to escape once it starts moving. Terrain traps, like gullies, cliffs, rocks, and tight trees, can make the consequences of a small avalanche worse. 

Avalanche Discussion

We're in the midst of a weather pattern that's shifting from cold and stormy to warm and wet. On Saturday at Tam Rim, the snow felt heavy and dense, yet there was light snow falling all day and wind transported snow was easy to observe along ridge tops. I was amazed to see melting snow dripping from trees alongside snow falling from the sky. It seems that Mother Nature is resisting the inevitable pull of Spring. 

Shifting weather conditions are a good reminder to keep your observation skills sharp when you're traveling in the backcountry. Up high, the snow is a little colder and can still be transported by the wind. Down low, snow is becoming wet and slushy will provide different signs of instability. Keep comparing the weather forecast to what you observe on the ground, and remember that public obs are super helpful to the entire backcountry community!
