Conditions Report
A powerful February storm cycle has dramatically reshaped what had been shaping up as a disappointing winter in the Sierra Nevada, dumping huge snowfall totals across the Tahoe region and rapidly boosting the seasonal snowpack.
According to the UC Berkeley Central Sierra Snow Lab, the Tahoe basin is now sitting at 98% of average snowfall for the season, a remarkable turnaround after the region was at just 60 % of normal on February 15 before the latest storms arrived. At Palisades Tahoe, one of the hardest-hit resorts, the snow piled up at an extraordinary pace. The resort reported 94 inches (about 8 feet) of snow over three days, including 21 inches in a single 24-hour period, with additional snowfall still expected.
The surge comes after weeks of concern across California’s mountains about thin snow cover and drought conditions that had left the snowpack weak and below normal for much of the winter. The recent storms reversed that trend in a matter of days, delivering some of the biggest midseason accumulations in years.
The Central Sierra Snow Lab, which tracks snowpack conditions at Donner Pass, said the rapid increase reflects how quickly major atmospheric storm cycles can transform seasonal outlooks in the Sierra, where a large share of winter precipitation can arrive during just a few major events. Palisades Tahoe said the deep new snow has created strong midseason conditions across the mountain, though the resort has also urged caution for visitors traveling into the area during the ongoing storm cycle.
Resort messaging encouraged guests to prepare before heading into Tahoe, noting that services can be limited during major storms. Travelers were advised to fuel vehicles, stock supplies, monitor weather forecasts, and carry proper traction devices due to hazardous road conditions.
For California, the snowpack carries importance beyond recreation. Sierra Nevada snow provides a critical portion of the state’s water supply, meaning large late-season storms can significantly improve outlooks for reservoirs and drought conditions.
While conditions have rapidly improved, forecasters note that the Sierra snowpack typically peaks in April, meaning additional storms in the coming weeks will determine whether this winter ultimately finishes above or below average. In the meantime, avalanche conditions are elevated and dangerous, and backcountry users are advised to exercise extreme caution while recreating in the mountains.
