Dangerous avalanche conditions exist in steep terrain where wet loose avalanches remain reactive to human triggering.
Minimize exposure to overhead hazard wherever possible.
Loose wet and wet slab avalanches are expected as warming continues, with no overnight cooling. Warming is amplified on sun affected slopes, particularly near rock outcrops.
No new avalanches were reported on Sunday.
On Saturday, loose wet avalanche activity, up to size 2, was concentrated to steep sun affected slopes in the heat of the day.
We expect natural solar-triggered wet loose avalanche activity and cornice failures to continue until temperatures return to below-freezing.
The upper 30 to 60 cm of the snowpack is wet from prolonged warm temperatures and strong sunshine. Saturated snow is struggling to bond to a thin melt-freeze crust or the dry snow found below it.
The mid and lower snowpack is well settled and dense, however, buried crusts may make sliding surfaces for avalanche activity as the warming affects deeper into the snowpack.
