Avalanche Summary

You could trigger a large avalanche in weak snow close to the ground on northerly and easterly aspects without any warning signs. A storm this weekend adds additional snow. You may not see widespread natural avalanches, but you can easily trigger an avalanche from below or from a distance, and the size might surprise you. On aspects with a buried weak layer, you can find safer riding on slopes less than 30 degrees unconnected to steeper terrain.

On other aspects, look for signs of storm instability, such as cracking and collapsing in new and wind-drifted snow. If you observe these behaviors, head to slopes sheltered from the wind or lower-angle slopes.
