Temperatures and danger ratings are falling.
Watch for changing conditions as you gain elevation, dry snow may be found in the alpine and large cornices are fragile.
Large, fragile cornices exist. Be aware of overhead hazard, and stay back from overhanging cornices on ridgelines.
Cornice falls may trigger slab avalanches on slopes below.
On Sunday, wet loose activity was reported at all elevations to size 2. In addition, several wind slab avalanches were reported.
As temperatures cool, wet loose activity is unlikely. If you are heading into the backcountry, consider sharing your observations and posting a MIN.
Overnight cooling will likely form a widespread surface crust. Beneath the crust, the upper snowpack will remain moist, gradually refreezing as temperatures drop.
Dry snow remains on the highest, north facing slopes spared from the warming. This sits over a hard crust below about 1900 m, and old wind-affected snow at upper elevations.
Two older crusts exist 1-1.5 m deep. While these are not a concern under cooler tempeatures, large cornice falls or the next wave of heat may wake these layers up.
