Moderate

Avalanche Summary

No new avalanches have been reported since the weekend.

Natural avalanche activity will increase on Wednesday as the sun affects the new snow.

Snowpack Summary

Roughly 10 to 30 cm of new snow has buried a widespread melt-freeze crust, existing on all but north-facing, alpine terrain.

A series of variable melt-freeze crusts exist in the upper snowpack.

The lower snowpack is generally well-bonded and strong.
