A record 13 backcountry skiers, climbers and hikers died in Italy’s mountains in the past week, including 10 fatalities from avalanches triggered by an unstable snowpack, prompting warnings to backcountry travelers as Winter Olympic competitions begin and authorities stress that managed Olympic sites remain safe.
Across the U.S. West, an extreme snow drought driven by unusually warm temperatures has yielded record-low snow cover, risking water resources and winter recreation from Utah to Oregon as bare ground becomes common and artificial snow is used in some locations.
California is officially drought-free for the first time in 25 years due to recent heavy rainfall and winter storms, filling reservoirs and alleviating drought conditions, though snowpack levels remain below average, leaving some uncertainty about future water supply.
Summit County in Colorado has recorded its lowest snowpack on record due to an unseasonably warm December, with temperatures among the hottest ever recorded in the state. Despite upcoming storms, the snow levels remain well below normal, exacerbating drought conditions across the region. Climate experts suggest that these warm and dry patterns are part of a broader trend linked to climate change.
A series of December storms has improved California's snowpack, which is crucial for the state's water supply, currently at 71% of average, though it remains below last year's levels. The snowpack acts as a vital reservoir, and its health depends on continued storm activity through winter and spring. Reservoirs are above average, but the overall water situation remains uncertain amid fluctuating weather patterns.
California's snowpack is currently below average at 71%, despite recent storms that temporarily improved conditions. The snowpack, crucial for the state's water supply, remains a concern due to variability influenced by atmospheric rivers and climate change, with the coming months critical for recovery. Reservoir levels are above normal, but the overall season's outcome remains uncertain, emphasizing the importance of continued storm activity.
California is starting 2026 with significantly below-average snowpack levels, at only 50% of the typical snow water content for this time of year, raising concerns about future water availability despite ample reservoir storage, as officials monitor the potential impact on water supplies amid changing precipitation patterns.
Colorado's snowpack is at its lowest level in over 50 years, which could lead to drought conditions and water shortages if the season doesn't improve in the coming months, though there is still potential for recovery in the snow accumulation during February to April.
Colorado's snowpack remains significantly below normal due to dry conditions and warm temperatures, with natural variability and La Niña influences playing roles; climate change may be contributing to the record warmth, but its impact on snowfall is less certain.
Warm weather and low snowpack are negatively impacting Western ski resorts, delaying openings and reducing snow-based attractions, while the Midwest and Northeast experience record snowfall, highlighting regional climate variability and concerns over drought and water supply in the West.
The Department of Ecology has declared a statewide drought emergency for most of Washington due to low snowpack and forecasts for a dry and warm spring and summer, making up to $4.5 million available in drought response grants. The declaration aims to address potential impacts on water users, agriculture, and wildlife, with climate predictions indicating warmer and drier conditions. Some areas, including the Olympic Mountains, Lower Yakima, and north Puget Sound, have significantly lower snowpack, and streamflows in many basins are already below 75% of normal. The drought declaration is a continuation of the 2023 emergency and will continue into next year, excluding limited areas in Seattle, Tacoma, and Everett.
California's above-average snowpack in the Sierra Nevada, while initially seeming like a positive sign, is overshadowed by the grim future of the state's mountain snowpack due to climate change. Rising temperatures will lead to a decrease in snowfall and faster snowmelt, posing risks of flooding and water scarcity. Efforts to address these challenges, such as increasing reservoir capacity, face bureaucratic and financial obstacles. The relationship between snowfall and climate change is complex, with various factors influencing snowfall patterns in different regions.
Despite California's mountain snowpack peaking just above its historic average, Governor Gavin Newsom urges residents to conserve water and not increase their water usage, as the state has endured years of dry weather and may face different conditions next year.
California's water supplies have been significantly boosted by above-average snowpack and rainfall, with the Sierra Nevada snowpack at 105% of average and major reservoirs at 116% of average levels. While this provides some breathing room, experts emphasize the need for continued water conservation and planning for future droughts and climate change impacts. Despite the current healthy water levels, the state still faces complex water management challenges, including fish population struggles and groundwater depletion, prompting ongoing discussions and plans for long-term water management and conservation efforts.
A study led by Northern Arizona University ecologist Andrew Richardson found that even slight increases in temperature in boreal forests can lead to a significant reduction in snowpack, resulting in increased plant stress, mortality, and potential fire risk. The research, published in the Journal of Geophysical Research: Biogeosciences, used long-term warming experimental results to show that less snowpack leads to warmer air temperatures and more snowmelt, with implications for ecosystem functioning and climate modeling. The findings suggest that transitioning to low- or no-snow winters could have major negative impacts on northern ecosystems.
