Recently formed storm slabs may still be reactive to human triggers. Use additional caution in shallow, rocky, or wind affected alpine terrain. Please post your observations to the Mountain Information Network.
Weather Forecast

Avalanche Summary
No new avalanches were reported on Sunday, however, there is currently very limited data for this region. Please report your observations to the Mountain Information Network(MIN).
Snowpack Summary
Observations are very limited in this region. Up to 40 cm of recent snow has created storm slabs at alpine and treeline elevations. Expect to find the mid-November crust down 60-80 cm. Average snowpack depths in the alpine are 110-150 cm with generally less snow in the southern parts of the region. Early season hazards such as stumps, rocks, and open creeks remain the primary concern below treeline.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
