Wind slab formation has been extensive and could extend into openings below treeline.

Seek out sheltered terrain where new snow hasn't been affected by wind.

Moderate

• We are uncertain due to a limited number of field observations.

No recent avalanches have been reported.

15 to 25 cm of new snow and extreme southwest wind have formed wind slabs in open areas at all elevations. The recent snow overlies a persistent weak layer.

At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.

In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 100 to 250 cm at treeline elevations.

• Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
• Be alert to conditions that change with elevation and sun exposure.
• Use ridges or ribs to avoid areas of wind-loaded snow.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
