Ongoing snow and wind are forming fresh storm slabs, further stressing weak layers deep in the snowpack. Very dangerous conditions persist, especially during heavy snow or strong winds.
Further snowfall and wind continue to add stress to buried weak layers. Facets, surface hoar, and crusts in the snowpack may become more reactive and have the potential to produce very large, destructive avalanches.
Ongoing snowfall and strong winds continue to produce widespread storm slabs. Expect larger and more reactive slabs in wind-loaded terrain, especially on north through east aspects.
A widespread natural cycle to size 3 occurred recently, with most activity on north through east aspects at treeline and alpine elevations. Avalanches ran within the storm snow and on buried weak layers.
Natural avalanche activity remains likely with ongoing snow and strong winds.
Strong southwest winds and ongoing snowfall continue to build widespread storm and wind slabs, especially at higher elevations.
Since early February, new snow has buried (and continues to load) a variety of old surfaces, including surface hoar, facets, and crusts. This weak layer is most likely in wind-sheltered terrain and is buried roughly 90 to 180 cm deep.
Below this layer, the remaining snowpack is generally well settled and well bonded.
