In sintesi

Human triggered avalanches with depths up to 2 feet are possible in very steep, shaded terrain above 8,000’ today. These avalanches may be triggered without warning and break wider than expected. Smaller wind slabs may also be triggered in very steep, upper elevation terrain that has been recently wind-loaded. Clear skies and warming temperatures will cause loose snow shedding in steep, south facing terrain by the afternoon. Evaluate the snowpack carefully for instability and give suspect terrain a wide margin today.

    Weak layers of snow including surface hoar and facets that formed during a month-long dry period in January are buried 1-2 feet below the surface on shaded slopes. Very steep, northerly aspects above 8,000’ are the most dangerous. Triggering an avalanche large enough to bury a person is possible in these locations today. Wind-loaded slopes will produce the largest avalanches, but avalanches are also possible in sheltered terrain. Avalanches involving weak snow from January may break wider than expected and could fail after multiple riders have ridden the slope. Though less likely, remote triggers may still be possible on isolated terrain features. Signs of instability including recent avalanches or collapses in the snowpack may not be present before triggering. Give yourself a wide margin of safety around very steep and shaded slopes today.

    These slabs were triggered by snowmobilers near Grouse Mountain last week.  Similar, but deeper, avalanche activity is possible on very steep, shaded slopes today.

    Moderate winds out of the west and southwest within the past 48 hours have redistributed recent snow and formed slabs up to a foot deep in wind-loaded, upper-elevation terrain. These slabs may be reactive to the weight of a rider on very steep slopes today. Warming temperatures and direct sun could increase the likelihood of triggering a wind slab later this afternoon. Although less likely, surface slabs have the potential to step down to deeper weak layers in very steep, north facing terrain features. If this occurs, avalanches may break deeper and wider than expected.

Avalanche Discussion

Today will be a beautiful day in the mountains. The sun will be strong and temperatures will be the warmest they have been in about a week. Small loose snow avalanches were observed in steep south facing terrain yesterday once the sun came out. Expect more shedding to occur today and adjust your travel plans accordingly. 

Small, recently formed wind slabs exist on loaded features at the highest elevations. Be on the lookout for these slabs and remember that small avalanches in consequential terrain can have a bad outcome.

Avalanches are still being triggered on the January Drought Layer in adjacent forecast zones. While avalanche activity involving this layer has been limited around Togwotee Pass, the upper snowpack structure is concerning and finding unstable snow is not out of the question on steep, north facing slopes. Give very steep and consequential terrain a healthy margin for the time being.

Please consider submitting an observation here if you are out in the mountains today. Recent observations have been excellent and improve our forecasts. Thank you!
