Storm and wind slab avalanches remain a lingering concern following stormy conditions earlier this week.
Continue to assess for signs of instability. Isolated storm or wind slabs may linger at higher elevations.
Storm and wind slab avalanches remain a lingering concern following stormy conditions earlier this week.
Numerous, natural loose wet avalanches up to size 2 were reported Wednesday, primarily on steep south-facing terrain and at lower elevations.
On Wednesday a few human-triggered storm or wind slab avalanches were reported throughout the region, occurring at treeline or above, and no larger than size 1.
Approximately 40 cm of recent snow has buried a widespread crust in all but sheltered, north-facing slopes where isolated pockets of surface hoar and/or faceted grains may exist below the new snow.
Previously problematic layers deeper in the snowpack appear to have bonded and strengthened, however, there is a low likelihood that they could remain a risk in steep, north-facing, high alpine terrain.
