Mammoth Basin Avalanche Advisory

Monday, March 27, 2017 - 6:27am

As of 5AM Monday morning, there are between 1 and 3 inches of new snow in the eastern Sierra, primarily north of Mammoth and at elevations above 7,000’. Southwest winds accompanied this fast moving storm and they will shift more to the north tonight (Monday) and Tuesday as temperatures rebound. Wind slabs will be our primary avalanche concern today at middle and upper elevations. As temperatures climb this afternoon and tomorrow, so will the risk of loose wet avalanches on solar slopes at middle and lower elevations. Natural avalanches will be unlikely, but human triggered avalanches possible. Evaluate the snowpack and terrain carefully to identify features of concern.
