    Recent new snow and winds will likely have formed reactive wind slabs, especially in wind affected areas.

Avalanche Summary

It is likely that a natural avalanche cycle occurred throughout the day, and overnight on Monday. 

Natural avalanche activity is expected to taper off somewhat throughout the day on Tuesday, however human triggered avalanches remain likely, especially in wind affected areas.

Snowpack Summary

20-40 cm of new snow is likely sitting on a mix of hard wind slabs, sugary faceted snow, and feathery surface hoar crystals, depending on location. Recent strong winds will have likely formed reactive storm slabs throughout the region. Total snowpack amounts are likely in the 60-120 cm range, tapering quickly at lower elevations.

Confidence

Moderate - Forecast snowfall amounts are uncertain.
