Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

By Wednesday afternoon, up to 20 cm of new snow is possible, accompanied by strong northeast winds.

Around 10 cm of dry, soft snow from the weekend may linger on shady alpine slopes, while a thick melt-freeze crust dominates elsewhere. This crust may soften during the day and refreeze overnight.

There are no concerning layers in the middle or lower snowpack.

The snowpack is rapidly melting at lower elevations.
