Hazard remains elevated due to warm temperatures, precipitation, and strong winds.

Moderate

• We are uncertain about how the snowpack will react to the forecast weather.
• We are uncertain due to a limited number of field observations.

On Saturday, a large size 2 avalanche was reported on a southeast face above Nak Bowl, traveling through a terrain trap and continuing down the bowl below. A few small wind slabs and one small wet loose slide from afternoon solar warming were also observed.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Approximately 60 to 100 cm of snow has accumulated over the past week, burying a widespread crust at treeline and below. In alpine terrain, this crust is likely thin or absent. Periods of strong southwesterly wind have redistributed the new snow in exposed areas at higher elevations.

A crust with facets may exist 100 to 200 cm below the surface, primarily on northerly aspects at higher elevations. This layer appears unreactive but continues to be monitored.

The remaining snowpack appears strong and well-bonded.

• Keep in mind that the high density of wet avalanches can make them destructive.
• Loose avalanches may start small, but they can grow and push you into dangerous terrain.
• Be careful as you transition into wind-affected terrain.
