Sierra Avalanche forecast
The Sierra Avalanche Center said Saturday's storm did not meet expectations but that there was enough to make triggering avalanches more likely on Sunday.
Avalanches are possible where weak snow sits below the surface or in places where wind-blown snow has piled up.
Experts believe the next storm, moving in Sunday night, will create impacts and the avalanche danger could reach 'high.' They are concerned about large to very large avalanches over the next several days, leading to an Avalanche Watch being placed into effect.
Sunday's backcountry forecast:
Below treeline: Considerable
Near treeline: Considerable
Above treeline: Considerable
Monday's backcountry forecast:
Below treeline: High
Near treeline: High
Above treeline: High
