Storm snow continues to accumulate atop a widespread crust. Use extra caution around recently wind-loaded terrain.
Several persistent weak layers of surface hoar, facets, or crusts may be buried in the top meter of the snowpack. Storm slabs could step down to these layers, causing larger-than-expected avalanches.
Snow since the weekend continues to accumulate atop a widespread crust. Expect slabs to be larger and more likely in wind-loaded terrain.
On Monday, riders triggered what they suspect was a large wind slab that ran on a crust near Bralone. Check the MIN report for details.
On Sunday, numerous wind slab avalanches (up to size 2) occurred in exposed terrain across various aspects, along with a few cornice failures.
Roughly 20 cm of storm snow has accumulated since the weekend, accompanied by strong, variable winds at higher elevations. A widespread crust, formed by last weekend's rain, lies just below the new snow. At higher elevations, new snow sits atop a generally settled, well-consolidated upper snowpack.
Variable weak layers buried throughout February may persist roughly 40 to 100 cm below the surface, in northerly high elevation terrain. These layers consist of surface hoar, facets, and/or crusts.
The remaining snowpack appears to be strong and well-bonded.
