Mammoth Mountain Ski Patrol manages some of the most complex weather-driven terrain in North America, where conditions can shift from 300 days of annual sunshine to extreme "thunder snow" and blizzard conditions with winds exceeding 100 mph.
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
