Lo esencial

The snowpack will take some time to recover from the heavy rain on snow event. Wet avalanches should still be at the forefront of your mind, so if you get out steer clear of large slopes, gullies and cirques that could continue to shed snow. Travel conditions may be arduous with a punchy, saturated snowpack.

    As the rain turns to showers, water will still be draining into and out from the snowpack. Wet slabs could be wide and entrain heavy debris as they flow downhill. Aside from wet slabs, avalanches may encompass a variety of all things wet on Wednesday including wet loose slides, glide slabs, and shedding pillows, and debris slides.  Because of the shallow snowpack, any slide is likely to scour to the ground. For glides, they may be more location dependent. Glide slabs may peel off smooth rocks or grassy areas. Often the same areas year after year will produce them, so use that local knowledge. 

    The mid and upper elevation slopes may take longer to change over and stabilize. At lower elevations the snowpack is dwindling, though you could still find an isolated slope with continuous snow cover here to watch out for. If you find yourself sinking deep into wet, unconsolidated snow, than don't go onto, or linger underneath large features. 

    Example large wet avalanche from Liberty Bell 3 path in January of 2021. Though the skies won't look like this tomorrow, the debris could. 

Avalanche Discussion

Freezing levels may have spiked at around 8,500ft Tuesday morning while heavy rain fell. We've lost about 6" of total snowpack depth at Washington Pass, and now temperatures are right around freezing again. 

Previously, professionals found from 2.5-5ft of snow on the ground between eastern and western parts of the Washington Pass corridor. Observers on Monday reported some whumphing collapses as low as 3,000ft near Cutthroat, and some shooting cracks higher up. A recent natural slab beneath the cliff on Hinkhouse Peak (see photo below) was spotted on Monday as well. While the snowpack slowly refreezes, travel may be difficult and may remain dangerous until temperatures cool. 

If you got out, please let us know what you found in the mountains by submitting an observation.
