Any overnight crust should soften quickly with daytime warming.
Wet loose avalanches become possible on steep slopes once the surface snow becomes wet.
Wet loose avalanches are possible in steep or extreme terrain when the snow surface is wet. Rocky outcrops are likely trigger points as they amplify warming.
Wet loose avalanches continue to be reported with strong sunshine and warm temperatures, primarily on south and east facing slopes.
Cornice falls have been reported. While they haven’t been triggering slabs on slopes below, they remain a significant hazard.
A thin surface crust may exist early in the morning, but we expect it to break down quickly on sun exposed slopes, and at low elevations with sunshine and warming. The snow below is likely moist or wet. Dry snow may still exist on the highest north-facing slopes.
A thick crust, with possible facets above it, exists 10–50 cm deep at treeline and above. Previous winds may have scoured exposed features down to this crust.
The mid and lower snowpack is well settled and strong. At low elevations, the snowpack is disappearing quickly.
