Snowpack Discussion

Dry snow may linger on shady north slopes in the alpine above 2200 m.

The snowpack is generally strong, with a typical spring diurnal pattern: daytime warming moistens the upper snowpack, then overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are experiencing an all-melt, no freezescenario and melting out quickly. Isothermal snow conditions exist below 1500 m.

Dormant weak layers may still exist in isolated alpine terrain, but likely require a very heavy trigger, such as a cornice fall. This should be on your radar with forecast high freezing levels, solar radiation, and a limited overnight refreeze.

Avalanche Activity

On Tuesday, a large cornice was triggered using explosives. This entrained wet snow on the slope below up to size 2.

Avalanche activity, such as wet loose and cornice falls, may increase with solar radiation, high freezing levels, and a limited overnight refreeze.
