MAKE IT RAIN — We were doing a great job fending off our editor's queries about whether the massive storms California's been getting over the past month will end its punishing drought ("Ask me again in two months!") Then came a story in the Mercury News last week with an eyebrow-raising assertion from Marty Ralph, director of the Center for Western Weather and Water Extremes at the University of California, San Diego: "If these storms continue to come onshore for the next two or three weeks, that will end the drought." Really? Can two months of storms erase three years of drought? In short, no, according to California's state climatologist, Michael Anderson. "He and I had a conversation about that," Anderson said Monday. Yes, California is getting a ton of water. It's on its fifth atmospheric river since late December, and three more storms are on the way over the next two weeks that could deposit 20 trillion gallons — enough to cover the entire state with a half-foot of water. But the state's main reservoirs are still below average for this time of year. The Colorado River system, which feeds California and six other Western states, is even lower. And 64 percent of the state's groundwater wells are also below normal. "Three years of critical drought takes a long time to recover from," Anderson said. "When you see all this rain come in and you think, 'Wow, that's really going to help that basin,' that's kind of where his mind was." (Ralph didn't respond to requests for comment.) Anderson had to hang up after 5 minutes on the phone ("I am a busy camper here.") But he stressed that it's too early to predict how the rest of the wet season, which runs through April, might turn out. "Our skill in that realm right now isn't very good," he said. Keep in mind that California also had a monster December in 2021, followed by the driest January through April on record. The situation certainly makes messaging difficult: "This really is, I want to say extraordinary, but I actually think it's more focused on yet another climate signal, in that California's experiencing, coincidentally, both a drought emergency and a flood emergency," California Department of Water Resources Director Karla Nemeth told reporters Monday. "We continue to be in a drought state of emergency as our traditionally wet season progresses."
