Natural slab avalanches were observed up to size 2.5 in the alpine on Saturday. A natural avalanche cycle up to size 3 likely took place on Sunday into Monday, consisting of storm slabs at upper elevations, with loose wet at lower elevations.
At upper elevations, around 60 cm of snow fell with strong wind over the weekend. In sheltered areas, the new snow may sit over a layer of weak, feathery surface hoar crystals. At lower elevations, the storm concluded with heavy rain on Sunday night, which will harden into a crust as temperatures drop over the day Monday.
Snowpack depths in excess of 300 cm can be found at treeline elevations.
