Highlights

Above freezing temperatures over the last 48 hours with possible rain today will cause wet snow avalanches across all aspects on steep terrain once the snow becomes wet and unstable. Monitor snow surfaces and choose lower angle slopes when you encounter unsupportable and mushy snow.  Be aware that larger avalanches are possible on steeper sustained slopes in confined features, such as gullies, that can entrain large amounts of snow.

    Temperatures remained above freezing for the second consecutive night. Natural and human triggered wet snow avalanches, primarily wet loose, will be possible on steep terrain across all aspects and elevations. Mixed precipitation and rain today up to ~8500 feet will further destabilize snow. Although less likely, wet slab avalanches could occur as free flowing water moves through the snowpack failing on hardness changes. Limit exposure below large sustained slopes or avalanche paths as these avalanches are difficult to predict. Avalanches will be more likely on terrain surrounded by rocks where the sun has heated surrounding snow surfaces.  Pay attention to the snow destabilizing if you sink deep into wet snow or if you encounter roller balls and pinwheels.

    Small wet snow avalanches are possible in lower elevations even during low avalanche danger. 

    Cornices: Large cornice falls are possible with the warmest temperatures all season. Avoid exposure below cornices and give them a wide margin of safety on ridgelines where they can break further back than expected.

    Wet avalanches are more likely around very steep, rocky, and confined terrain.

Avalanche Discussion

Dreary Spring Day

Warm temperatures continued through the night 33-40°F in the mountains. A light superficial refreeze will break down quickly today, starting the process of the snow becoming wet and unstable. Beneath the surface, water has slowly been percolating through the snowpack. Predicting if and when the free flowing water will cause wet slab avalanches can be difficult. For this reason, it’s better to play it safe when dealing with uncertainty. Get up and get out of the mountains early. Possible rain this afternoon certainly won’t help the riding quality or stability. Assess the stability of wet snow as you travel into higher terrain and out of the valley inversions first thing this morning. The good news is that cloudy skies will slow the process of warming. The bad news is those clouds can cause a greenhouse effect and keep the snow warm. You’ll likely find a mixed bag of conditions out there.

Human Factor 2.0 Backcountry Recreation Survey

For years, the avalanche community has worked to understand and address the human factors that influence decision-making in the backcountry. The project's first stage involves interviewing backcountry recreationalists who have been traveling in avalanche terrain for at least one season. All participants will be entered to win amazing raffle prizes (from Jones Snowboards, BCA, and more!). If you’re curious about being involved, please take 1-2 minutes to fill out our basic initial survey.
