Although shallow, the wind slabs will be increasingly reactive throughout the day on Sunday.
Continue to practice good travel and group management habits by skiing the committing lines one at a time and regrouping in safe areas.
The wind slabs will develop throughout the day, Sunday, and could reach up to 20 cm deep by the end of the day. On solar aspects, and below 600m, these slabs will rest on a thin melt-freeze crust, due to the mild temperatures and the sun of Saturday.
A few wet loose avalanches of size 0.5 were observed directly below rocks, on sunny slopes.

The top of the snowpack consists of 10 to 25 cm of new snow with surprisingly little wind effect from Thursday's storm, other than very soft waves of snow on the SW-S-SE aspects. Below 600m and at all elevations on the solar slopes, this new snow is moist on the surface, and should freeze overnight Saturday into Sunday. The mid-snowpack is well consolidated, and right-side up, interspersed with several melt-freeze freezing crusts from the last few weeks.
