In sintesi

Consider avoiding large, complex, unsupported slopes—especially those with terrain traps below that would amplify the consequences of a slide. Wind-loaded areas are most likely to produce larger, more reactive avalanches, but you there's still a chance you could trigger an avalanche lower down on steep, sheltered slopes.

    Your biggest concern is triggering even a small avalanche in complex terrain. A minor slide could knock you off your feet and carry you over cliffs, across hard crust or rocks just beneath the new snow, through trees, or into a gully where debris can pile up deeply.

    Slopes are gradually stabilizing after about six inches of snow fell before Valentine’s Day. Observers n neighboring zones reported that triggering avalanches became more difficult by Sunday, even in steep, unsupported terrain, with most activity limited to loose dry avalanches.

    Wind slabs remain the most likely place to trigger a larger, more reactive avalanche. However, lingering persistent weak layers could still produce small but surprising avalanches in atypical, non–wind-loaded terrain—such as sheltered, steep areas farther downslope. Snow continues to slide easily on the crust beneath the new snow and at the interface with older, dry snow on shaded aspects.

    A complex array of crown lines and human triggered avalanches in high consequence terrain where getting caught in an avalanche, even if small, could result in hitting trees or getting buried deep in a gully. This is where someone was caught and carried in an avalanche in the West North zone on Saturday.

Avalanche Discussion

Expect overcast skies Monday with maybe an inch of light, fluffy snow. Southerly aspects will have a surface crust beneath this new snow, formed during Sunday’s intense sunshine. On Sunday, dry loose avalanches ran on shaded slopes, while sunlit slopes produced slow-moving moist and wet loose avalanches, in some cases gouging down to the crust. Look for chunky, hard debris piles in these areas on Monday.

The lower elevation band, and even areas with tree canopies in the mid-elevation band, have very little snow cover right now. There may be a few shady, open slopes near the top of the lower elevation band that have enough of an old, smooth snow surface to produce an avalanche.
