Storm snow has settled more than expected but human triggering remains likely.
Avoid consequential terrain and be mindful of your overhead hazard at all elations.
Expect the hazard to rise near the end of the day during peak warming.
A persistent weak layer (PWL), buried March 5th, is now down 60-120cm in the snowpack. Depending on aspect and elevation, this layer may be suncrust, facets and/or surface hoar.
Wet loose or storm slab avalanches may step down to this layer resulting in large avalanches.
Aprrox. 25cm of snow arrived on Sunday with warm temperatures creating a widespread storm slab which will be reactive to human triggers. Storm slabs will be most reactive in terrain exposed to the SW winds or at lower elevations where rain or warm temperatures have created a more cohesive slab.
Wet loose avalanches will be likely at lower elevations during periods of rain or late in the day during peak warming.
Avalanche control using artillery at Rogers pass on Sunday night produced avalanches up to size 3.5.
Natural avalanche activity tapered off as storm intensity eased with no new natural avalanches observed on Monday.
Additional moisture & elevated freezing levels continue until Friday.
