Lo esencial

Avalanches are unlikely in the East South Zone. The snowpack is strong but shallow with inconsistent coverage. You may find isolated wet snow conditions high in the alpine and close to the Cascade Crest, but open creeks and challenging travel conditions will be your greatest hazard.

    Friday should be the first clear day following a week of rain, snow, and cloudy skies. As the sunshine thaws recent surface snow on E-S-W aspects, there is a chance for additional wet loose avalanches. Of most concern are areas closer to the Cascade Crest near Chinook Pass and Bumping Lake that received more snow since 2/28. Be on the lookout for fresh rollerballs and pinwheels, especially around rocky outcrops in direct sun.  Use caution if traveling in steep consequential terrain, and be aware of rocks, cliffs, open creeks, and other obstacles that can increase the consequences of being caught in even a small avalanche. If you are sinking deeply into wet, heavy snow, or snow slides easily off of small steep test slopes, it is best to stick to low-angle terrain.

Avalanche Discussion

Most of the east south zone suffers from inconsistent and low snow cover. The prolonged dry and warm weather of January and February really took a toll on the snowpack, and the recent atmospheric river only deteriorated conditions further. Much of the snow melted back to bare ground at lower elevations, making access challenging in some parts of the zone. Similarly, shallow spots in the snowpack on more southerly slopes and near ridges shrunk, exposing rocks, trees, and dirt. You can expect deep, soggy, and challenging travel through wet unconsolidated snow in areas where you find a consistent snowpack. The snowpack increases dramatically as you gain elevation, especially on shady northern aspects. For more information on how our current snowpack compares to seasonal averages, check out the monthly Climatological Snow Depth Report.
