Avalanche Summary

Consecutive nights of weak or non-freezing temperatures followed by warm and sunny weather increase wet avalanche hazard. If you sink into wet snow deeper than your boot tops, move to colder slopes or exit the mountains. Start and end your day early to limit exposure. Remember, even a small avalanche can have a dangerous outcome if triggered in consequential terrain above cliffs or exposed rocks. Cornices in the alpine are also weakening. Give cornices a large berth while traveling along ridges and limit exposure with cornices overhead.

Thursday afternoon, a storm system moves in from the Great Basin, bringing cooling temperatures and light snowfall. As the snowpack refreezes, the hazard of wet avalanches will decrease.
