Avalanche Summary

While no significant avalanche activity has been reported this week, wind slab avalanches probably occurred during the height of Thursday’s storm.

Snowpack Summary

Up to 30 cm of new snow is possible in higher terrain, and it’s likely to be heavily wind-affected. Amounts will taper off quickly below treeline, though the exact rain-snow line remains uncertain.

The new snow is expected to bond well to the strong and settled snowpack.

Lower elevations continue to melt out rapidly.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
