A thick crust has formed near the snow surface at all elevations with limited new snow above it -- be cautious of poor snow quality and newly-formed wind slabs.

Weather Forecast
The next wave of precipitation is expected to begin Saturday evening and may transition from snow to rain to snow again.SATURDAY: Mostly cloudy with isolated flurries, light to moderate southwesterly winds, freezing levels near 1500 m. Snowfall to begin Saturday evening.SUNDAY: 10-20 mm precipitation throughout the day with snow switching to rain Sunday morning, moderate to strong southerly winds, freezing levels rising to around 2200 m.MONDAY: A mix of sun and cloud, light to moderate westerly winds, freezing level near 1200 m.
Avalanche Summary
Many loose wet avalanches were observed on Thursday. Temperatures cooled down on Friday and wet avalanche activity has quieted down. We currently have very limited observations in this region; please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
The depth of the snowpack varies greatly with elevation. Recent reports suggest the average depth is 150 to 200 cm in the alpine, 100-150cm at treeline, and decreasing rapidly below treeline where the primary hazards are rocks, stumps, and open creeks.10 to 20 cm of new snow and moderate to strong winds may have formed wind slabs at treeline and alpine elevations. The new snow sits on a thick crust formed from the rain that fell to mountain tops on Wednesday and Thursday. The snowpack shrunk with the rain and should be well-settled at all elevations. The major feature in the snowpack is a deeper crust which was formed at the end of October and can be found approximately 100 cm below the snow surface at treeline elevations.We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.
