Avalanche Summary

The snowpack in this area is consistently more shallow than other areas of the Southern Mountains. You could trigger an avalanche that breaks on weak layers in the top meter of the snowpack. This is most likely near trigger spots like steep convex rollovers, below ridges and cliffs, and near rock outcroppings. Avalanches will be larger on northerly and easterly slopes. Assess each slope you plan to travel individually and identify and avoid shallow trigger points.

After multiple days of warming, loose wet avalanches are less likely, but not out of the question in the afternoon. Avoid traveling on or under slopes where you observe rollerballs, pinwheels, or fan-like point releases.
