While wind and snow should ease through Thursday, dangerous avalanche conditions may persist. Avoid avalanche terrain during heavy snow or strong wind.
Snow since the weekend continues to accumulate atop a widespread crust or firm wind-affected surfaces. 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 10 to 40 cm of storm snow has accumulated since the weekend, accompanied by strong, southerly 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.
A crust with facets is buried roughly 40 to 100 cm below the surface. While this layer has not produced any recent avalanche activity, it continues to be monitored as new snow accumulates above.
The remaining snowpack appears to be strong and well-bonded.
