Be aware of overhead hazards, like cornices and large slopes.
Reduce your exposure during the heat of the day, when it is windy, and when new snow or rain are in the forecast.
As temperatures rise, large cornice falls will become a concern. They can potentially trigger persistent slabs on the slopes below. Evidence of recent cornice falls has been reported in the region.
Facets and/or surface hoar buried 40 to 80 cm deep are most prominent at upper elevations where no surface crust has formed. Surface instabilities or large triggers may step down to these deeper layers.
Several cornice triggered avalanches were reported in the past week.
If you do observe an avalanche, please share your observations on the Mountain Information Network.
Variable wind-affected snow covers open terrain at upper elevations. A crust is found up to 2000 m and higher on solar slopes.
Three layers of concern currently exist in the upper-mid snowpack. Surface hoar and a crust that formed in mid-March can be found 30 to 70 cm below the snow surface. Below this, another layer of surface hoar that formed in early March can be found at a depth of 60 to 100 cm. Additionally, a layer of facets, surface hoar, and/or a crust from mid-February is buried 120 to 200 cm deep.
The remainder of the snowpack is well consolidated, and there are no current concerns.
