Pay attention to accumulating snowfall - avalanche hazard will increase as the next storm brings more snow and wind.

    Another storm begins Monday. Storm slab size and sensitivity will increase along with accumulating snowfall. At lower elevations, fresh snow may now provide enough coverage to reach the threshold for avalanches.

Moderate

Avalanche Summary

This MIN reports a remotely triggered avalanche on Saturday around the Coq Summit. With more snow and wind forecast, expect to find a more reactive storm slab as snow accumulates.

If you head into the backcountry by any method of travel, please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

Another system of heavy snowfall and wind is forecast to begin Monday.

20-50 cm storm snow and older more, settled snow covers a crust and well-settled snowpack in the alpine and upper treeline. Strong SW wind may have redistributed loose snow to lee features.

Snowpack depths range from 80-160 cm and decrease rapidly at lower elevations.

Terrain and Travel Advice

  • Watch for avalanche hazard to increase throughout the day.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Dial back your terrain choices if you are seeing more than 25cm of new snow.
  • Investigate the bond of the recent snow before committing to your line.
