The recent storm snow may still be reactive to human triggering, especially in wind-loaded terrain at higher elevations.
Cornices are large and fragile following the recent stormy conditions. Use caution around cornices, particularly during periods of sun.
Storm snow accumulated since Friday is expected to remain reactive to human triggering at higher elevations, particularly in wind-loaded areas or where the new snow has not bonded to an underlying crust.
On Friday, this MIN report includes observations of recent wind slab avalanches on north through east aspects around treeline.
If you are heading into the backcountry, please share your observations by posting a MIN.
Approximately 10 to 30 cm of dry, low-density snow overlies a thin crust in most areas at elevations of 2000 m and below. Below this crust, moist snow may persist, particularly at lower elevations.
A thicker crust buried earlier in March is present 50 to 80 cm below the surface at treeline and below. The early February crust is found at depths of 100 to 160 cm. These deeper layers are not currently a concern.
The remainder of the snowpack is generally well settled and bonded.
