Avalanche Summary

No new avalanches have been reported.

If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

Forecast strong southwesterly winds are expected to blow loose snow into wind slabs on leeward north and east facing slopes near ridgetops.

5 to 20 cm of new snow at upper elevations is covering a variety of surfaces including surface hoar on sheltered features and a sun crust on steep south facing terrain.

We are not tracking any concerning weak layers in the mid or lower snowpack at this time.

Snow depths vary across the region. Currently near Mt.Washington, 135 cm is reported at 1100 m, and 250 cm at 1500 m.
