  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

15 to 25 cm of new snow and strong southwest wind may form wind slabs at treeline and above. 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.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • 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.
