Weather dictates daily patrol priorities, particularly regarding safety and terrain access:

Ski Patrol relies on a dense network of over 20 weather stations providing 15-minute real-time updates. Key stations include: The Summit at Mammoth 3-star hotel Mammoth Lakes, CA

Acts as a mid-mountain benchmark for temperature and humidity. Mammoth Mountain Main Lodge Ski resort Mammoth Lakes, CA

High winds frequently trigger "weather holds" for upper-mountain lifts like Chair 23 and the Gondolas. Only a few chairs, such as 8, 17, and 21, are relatively protected and remain operational during moderate wind events.

Monitors base-level accumulation and freeze-thaw cycles that impact lower-mountain grooming.

The "Top" (Summit) often remains closed until patrol can verify stability after high winds and heavy snowfall (e.g., 75+ inches in 48 hours) create highly unstable snowpacks. Safety & Real-Time Reporting
