Rain-on-snow could present fresh risks to California’s snowpack. Here’s why
The gargantuan California snowpack, over twice the normal size for this time of year in some parts of the Sierra, just keeps growing. On Tuesday, yet another storm unloaded several feet of snow in the Lake Tahoe area, completely burying the Sugar Bowl Resort office. Ideally, the snowpack gradually melts during the spring and summer, releasing water when reservoirs aren’t capped by flood control limitations and can maximize storage. All the snow right now is fantastic news for the state’s enduring drought. … But the overabundance also presents potential flood risks. … A spring heat wave, for example, could drive an early melt that results in flooding. A warm atmospheric river aimed at snowcapped mountains could also rapidly melt snow and overload watersheds.
