Ski Conditions and Weather
As of this writing, the Sierra Nevada is in the midst of an unprecedented heat wave. Temperatures are forecast to hit 70°F over the next four days! Although this winter started with average precipitation amounts, we are now entering a warm (vs. "dry") snow drought (https://www.drought.gov/topics/snow-drought). For perhaps one of the first times since 1926, snow surveyors such as us have been requested to perform mid-month snow surveys in attempt to capture how quickly this snowpack is disappearing. As drought.gov states, "Every major river basin in the West experienced its first or second warmest winter (December, January, and February) on record."
That said, it feels rather absurd to state that "ski conditions were good this week in Tuolumne Meadows." But mental health is important too. And groups like the Yosemite Winter Club have been coming out here since 1928! Recreation and tourism are crucial to gateway communities.
Avalanche and Snowpack Conditions
Snow Creek Cabin has closed early due to lack of snow. Snowline in that zone is just below Tioga Road in this area. The road corridor still has ample snow to ski east of Tioga Pass to the Warren Fork. Last week, overnight lows resulted in a decent freeze of the snow surface here in the Tuolumne Meadows zone. The remote weather stations in the area, however, have been reporting above-freezing temperatures at the higher elevations for the past couple of nights. Vogelsang, for example, has been reading overnight lows in the 40s. Due to solar effects and hot temperatures, snow surfaces are rapidly becoming more textured (or non-existent!) as this water percolates towards the bottom of the snowpack. The Tuolumne River gage is now potentially peaking around four feet.
Normally, time of day and thawing play the biggest roles in the avalanche hazard in "springtime." But things are not "normal," so be vigilant no matter when or where you are travelling in the mountains until conditions stabilize. If you're lucky enough to find a snow bridge, do not trust its integrity. And it may be gone when you return. Dry logs may become submerged as well. Don't anticipate crossing frozen lakes on ski tours. Have contingency plans. Maybe it's time to relax and do a bird count.
