Summary

After a mild overnight low of 30.9°F and a current snowpack depth of just 11 inches—about 38% below average—Mother Nature is finally delivering the winter magic skiers have been waiting for. Over 10 inches of fresh snow are expected today, with an impressive 34 inches in the five-day forecast, promising a major boost for base conditions. Despite the lean start, today’s softening groomers and a new blanket of powder are setting the stage for some thrilling turns, especially on the steeper terrain Sun Valley is famed for.

The resort is rebounding from recent challenges. While the Warm Springs Lodge continues to assess damage from a major fire, the mountain remains open and poised for a dramatic holiday week. A huge 29-inch single-day snowfall earlier this week sparked excitement and a reminder of the mountain's raw power. With upcoming lift upgrades and Dollar Mountain set to open this weekend, Sun Valley is not only preparing for a strong season turnaround but also reaffirming its status as a premier winter destination. Adventure-seekers, pack your powder skis—Baldy is getting ready to shine.
