Summary
The current snowpack stands at 39 inches, though it's just 58% of the seasonal average, indicating a slower start to winter. However, conditions are expected to change dramatically, with a significant storm system forecasted to deliver up to 8 inches of fresh snow over the next five days. While the 72-hour outlook only calls for a modest 0.49 inches, anticipation is building for powder days ahead as the Sierra braces for a much-needed snow boost.
Despite an early season avalanche that tragically claimed the life of a ski patroller, Mammoth Mountain is pressing forward with continued vigilance and strong safety protocols. The resort is fully operational, drawing excited crowds eager for the new snowfall and extended ski season, which is already slated to stretch into June 2026. With the newly opened D-Line Chairlift and bluebird conditions expected to follow the upcoming storm, skiers and riders can look forward to refreshed terrain and expanding access across the mountain. A mix of solemn remembrance and renewed energy defines the slopes today.
