Begin your day early and steer clear of avalanche terrain while daytime warming and sun effect weaken a supportive surface crust.
Persistent slab avalanches remain possible, especially later in the day as the surface crust deteriorates and surfaces become moist from daytime warming and/or solar effect.
Expect wet loose avalanche activity to increase with daytime warming and solar effect.
These may step down to deeper layers resulting in larger-than-expected avalanches.
Several large natural persistent slab or wet slab avalanches (up to size 3) have been reported since last Friday.
Pinwheeling and loose wet avalanche activity has been reported recently, primarily in steep south-facing terrain.
A widespread melt-freeze crust exists on the surface. Expect the crust to deteriorate, and the surface snow to become moist at lower elevations and south-facing terrain throughout the day.
A layer of weak, faceted crystals over a crust, or surface hoar, remains the primary layer of concern, buried approximately 40 to 80 cm deep.
