California has finally broken its 25-year drought streak, marking the first time in a quarter-century that no part of the state is experiencing abnormally dry conditions. The respite comes as a welcome relief to residents who have endured two of the worst droughts on record, devastating wildfires, and the most destructive blazes ever.
The latest bout of extreme weather brought much-needed rain, filling reservoirs and leaving the state unusually wet for this time of year. In fact, California's 14 major water supply reservoirs are now at a healthy 70% capacity, according to the California Department of Water Resources. The news has sent shockwaves of optimism through Golden State communities.
The recent precipitation has also led to an end to the drought conditions that plagued California for over 1,300 days. Last seen in February 2020 and lasting until October 2023, this was followed by another severe drought from 2012-2016. However, it's been a while since the state experienced zero drought conditions.
"We're seeing a welcome respite from the worst of the droughts," said University of California climate scientist Daniel Swain. "This is certainly a less destructive weather winter than last year was and many of the drought years were." He cautioned that in the long run, however, residents can expect to see more extreme swings in weather patterns due to climate change.
Climate scientists have coined a term for this phenomenon, known as the atmospheric sponge effect, which describes how warming leads to deeper droughts and the release of moisture in fewer but more intense rainstorms. This pattern is becoming increasingly prevalent across the state, contributing to the cyclical nature of wildfires.
Last year's devastating Palisades and Eaton fires serve as a prime example of this effect. The area experienced an extreme shift from very wet conditions during the winter months to prolonged drought periods later in the year, ultimately exacerbating the risk of catastrophic wildfires.
The latest set of storms has brought snow to the Sierra Nevada mountains but left the state's snowpack below average. Furthermore, much of the Western United States has seen warmer-than-average temperatures and relatively little snow so far this winter. The strain on the already over-tapped Colorado River adds another layer of complexity.
While California is currently clear of water supply risks and wildfire danger for several months to come, scientists warn that residents should expect more extreme weather whiplash in the long term. As Swain noted, "We don't even have to be in a notable multi-year drought to see these kinds of sequences lead us to catastrophic fire conditions."
