Dangerous Avalanche Conditions.
Beware of overhead and adjacent slopes. Remote triggering is a concern, avalanches have run full path.
Solar input could further weaken the snowpack.
Wind slab could be found on all exposed slopes at treeline and above.
these avalanches could step down to deeper layers.
Solar Input could increase the likelihood of triggering.
A weak layer of faceted grains above a crust buried 60 to 120 cm deep is a recipe for large, high-consequence avalanches. Remote triggering is an ongoing concern.
Avalanches triggered on this layer could run full path.
The wind has come from a variety of directions, wind effect could be found on all exposed terrain at higher elevations. A new crust or moist snow will be found on south and west facing slopes.
40 to 80 cm overlies a layer of surface hoar in wind-sheltered terrain, weak facets, or a hard melt-freeze crust on south and west-facing slopes.
A thick and hard widespread crust that formed in early February is buried about 60 to 120 cm deep. This crust may have a layer of facets above it. The snowpack below this crust is generally not concerning except in shallow alpine terrain.
Check out this MIN for photos of sled triggered avalanches in Allan Creek and this one for a skier triggered avalanche.
Human and naturally triggered avalanche activity continues throughout the region with avalanches ranging in size from 1.5 to 3.5. Some avalanches have run full path to valley bottom. Many human triggered avalanches have been remotely triggered and also resulted in sympathetics.
We expect this type of avalanche activity to continue.
