Highlights

Heightened avalanche conditions exist at low and middle elevations. Natural and human-triggered avalanches are possible in steep terrain where meltwater from several days of heating has weakened the top 1 to 2 feet of snow.  Evaluate steep slopes carefully and look out for softening snow surfaces and rollerballs as temperatures warm this afternoon. Minimize your time spent on and under very steep slopes.

    Wet snow avalanches remain possible once snow surfaces soften this afternoon. The danger is highest on very steep slopes and around cliffs that will expedite heating. The main concern exists where water has reached crust/facet interfaces in the top portion of the snowpack. There is less of a problem in lower elevation terrain, but specific slopes that harbor more snow and crust interfaces could be affected by remaining meltwater. Avalanches with start zones in middle elevations also have the potential to impact low-elevation areas.  While unlikely, wet avalanches could occur in isolated areas at upper elevations if we get enough heating by this afternoon.

    Wet slab avalanches are hard to predict and can occur naturally. Limit your time traveling in or under large start zones and avalanche paths. Minimize time on steep slopes with softening surfaces and watch for rollerballs. Dig down to determine if there is still wet snow underneath any thin crusts.

    A large natural wind slab yesterday that was most likely cornice-triggered.

    Old wind slabs will have increased sensitivity during peak warming, increasing the likelihood of natural and human triggering.

Avalanche Discussion

Cornices - Cooler temperatures should help stabilize cornices, but after several days of warm temperatures, they could remain a little sensitive today. I would still give them room and minimize my time underneath.

Several bear sightings have been reported this spring. When planning for the day, bear spray, group travel, and appropriate food storage should be considered.

Also, please remember that closed ski areas are now uncontrolled and could have avalanche problems.  Keep this in mind if skinning up or skiing on very steep ski area runs.
