Poor - Due to limited field observationsfor the entire period

Friday: Mostly clear with freezing levels at sea level and Alpine temperatures as low as -17 Celcius. Strong Northeasterly outflow winds developing throughout the day.Saturday: Increasing clouds and warming trend as winds shift to westerly, but freezing levels remaining at sea level.Sunday: Light snowfall increasing throughout the day with gradual warming

I suspect there was a decent natural cycle during the storms earlier this week, especially on wind-loaded slopes. The possibility of human-triggered wind and storm slab avalanches is expected to remain for the forecast period.

Another 10-15cm adds to the recent storm snow totals. Varying temperature, precipitation intensity, and wind throughout the recent storms have probably resulted in weaknesses strewn throughout the top metre or so. However, the relatively warm post-storm temperatures on Thursday should favor settlement and strengthening. The mid and lower snowpack is generally well settled and strong, with an old rain crust near the ground.
