Snowpack Summary

New snow is gradually accumulating, with heavier snow on Monday expected to bring the storm totals into the 20 to 40 cm range. Surface conditions will be shaped by northeast winds that are forecast to increase throughout the day on Sunday.

Snow depths in Long Range Mountains average about 80 cm in wind-sheltered areas and are much more variable in wind-exposed areas. The snowpack structure is strong and bonded.

Cornices have been forming along northeast-facing ridges.
