10 to 25 cm of recent snow and extreme southwest wind have formed wind slabs in open areas at all elevations. The recent snow overlies a persistent weak layer.
Wind slab formation has been extensive and could extend into openings below treeline.
Avoid slopes that have been wind loaded.
10 to 25 cm of recent snow and extreme southwest wind have formed wind slabs in open areas at all elevations. The recent snow overlies a persistent weak layer.
Rain may trigger wet loose avalanches.
No new avalanches have been reported. However, observations are currently very limited.
15 to 25 cm of recent snow and extreme southwest wind have formed wind slabs in open areas at all elevations. The recent snow overlies a persistent weak layer.
At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.
In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.
The mid/lower snowpack is generally well settled and strong.
Snowpack depth ranges between 100 to 250 cm at treeline elevations.
