Ridgetop winds remain light.MONDAY: Cloudy with light snow 5-10 cm. Freezing levels 1700 m and alpine temperatures near -1.
Avalanche Summary
On Thursday, several loose wet avalanches up to size 1 were reported from steep solar terrain at lower elevations. Explosive control produced a size 2.5 loose wet avalanche on a southwest aspect between 1750-2050 m. It ended up triggering three slabs that failed at the ground. Active cornice control using explosives also produced a size 3 cornice failure which did not pull a slab avalanche from the slope below.Natural avalanche activity may start to slowly taper off with cooler temperatures this weekend. Human triggered avalanches are possible especially at lower elevations on southerly aspects due to a lack of re-freeze.
Snowpack Summary
Snow surfaces are variable. On higher North aspects (above 1700 m) you may find some dry, faceted snow. Some of this has been redistributed by southwesterly and northerly winds, potentially creating some isolated wind slabs. On solar aspects (East, South, West) at treeline and in the alpine the upper 10-30 cm will likely sport a firm crust with cooling temperatures. Below treeline the snow could remain moist or wet if it doesn't re-freeze. The snowpack has gone through a lot of change with the hot and sunny weather. The mushy snowpack will start to solidify and lock-up allowing for hard conditions and less avalanche activity, especially on the solar slopes.
