Ski Conditions and Weather
The wind storm is over! Mono winds can reach speeds of 50 to over 100 mph. According to the National Weather Service, they are localized winds that typically start east of the central Sierra often near Mono Lake and then travel up and over the mountains to the western foothills gaining speed as they descend, especially once they hit funneling terrain features (like canyons). Weather nerds know them as katabatic, meaning to travel downhill. The Mono Winds are colder and more humid than the Santa Ana Winds but both typically occur between October and April. This week was quite reminiscent of our first winter season when we were welcomed with a sparse snowpack and our first Mono wind storm. That one, which occurred the evening of November 30, 2011 to December 1, 2011, left over 400,000 downed trees in its wake. At the time of this writing, damage is still being assessed and Yosemite National Park remains closed. But, a change in weather is in the air and snow is in the forecast.
The warm temperatures, followed by the high winds, have left a mixed bag of snow surfaces out there. Textured, refrozen, and now littered with debris (pine needles, cones, etc.), even a ski optimist would have a hard time saying anything good about the present conditions. Coverage is still decent and touring opportunities exist in drainages and meadows above 8,600 feet.
Avalanche and Snowpack Conditions
Please refer to the Eastern Sierra Avalanche Center (ESAC) for the avalanche advisory for this part of the Sierra Nevada. There are online educational opportunities on the site too. The most recent was “Introduction to Backcountry Travel-Back to the Basics,” and is excellent.
The avalanche hazard in the Tuolumne Meadows area is low. The primary hazard out there now is the many obstacles that lurk on or below the surface. Now is a good time to get out and cross-country ski and leave the downhill skiing for a time when the snow is deeper.
The American robins have been out and about in rather large numbers congregating peacefully among the western junipers of Lembert Dome. We also saw a few red-breasted nuthatches and brown creepers out looking for insects during the warm spell. And a great horned owl hooted in the distance one calm, quiet evening.
The Tuolumne Meadows Ski Hut is closed for the 2020-2021 season.
