Snowpack Summary
Significant changes happening in the forecast region. New input of snow, wind or sun are having a dramatic effect to the hazard depending on asp, elevation and geographic location. Surface instabilites, like new snow, wind-pressed, transported or temp related will trigger and entrain facets, likely other deep instabilities. Strong caution advised.
