    Recent moderate to strong wind and heavy precipitation has formed storm slabs that increase in depth and reactivity with elevation. Expect deeper slabs and touchier conditions on the lee side of wind exposed terrain features.

    With the potential of extended sun exposure on Thursday, expect the snow surface to stay wet below tree line

Confidence

Moderate - Timing or intensity of solar radiation is uncertain on Friday

Weather Forecast

FRIDAY: Mix of sun and cloud / Light south wind / Alpine temperature 1 / Freezing level 1300mSATURDAY: Flurries, accumulation 5-10cm / Moderate west wind / Alpine temperature 1 / Freezing level 1300mSUNDAY: Mix of sun and cloud / Light to moderate northwest wind / Alpine temperature -1 / Freezing level 1000m

Avalanche Summary

On Friday expect human triggering of storm and wind slabs to still be possible in the alpine and tree line elevation bands where the recent precipitation has fallen as snow.

Snowpack Summary

Tuesday and Wednesday saw very heavy amounts of precipitation. The freezing level hovered around tree line during that time, however it can be expected that 70-100cm of snow fell at upper elevations. The new snow would have been redistributed by moderate to strong southwest wind and is sitting on a well settled lower snowpack. Rain below tree line has soaked an already moist and/or wet lower snowpack.
