Reporters who slog through a meadow near Lake Tahoe next week for California’s first manual snow survey of the season will find copious amounts of snow. The state Department of Water Resources’ electronic readings on Dec. 29 showed a statewide snowpack at 156% of normal as a persistent parade of storm clouds has pelted the West Coast in December.
Some western residents are breathing a sigh of relief after recent atmospheric river storms have drenched the drought-parched region, and more are on the way. However, scientists caution that it is too early to celebrate. “At this point in time, we still have another four or five months in our snow season and in our typical rainy season,” said Andrew Schwartz, lead scientist at the Central Sierra Snow Lab.
People don’t eat much alfalfa, at least not directly. But the crop widely grown throughout California and the West to feed cows across the world has become central to discussions about managing a future with limited water. That’s part of the larger debate over what’s being grown and where it goes, and even what people should eat to ease pressure on the water supply and fight climate change.
The grass beneath the palm trees at the Foothills has no function other than to look lush and inviting for people driving up to the gated community’s entrance. The homeowners’ association there, like many that govern such developments dating to the 1980s and 1990s, was still sprinkling Colorado River water on about 50,000 square feet of turf this year.
Eight of the top 10 warmest years on record occurred in the last decade. The snowline where rain turns to powder continues to move uphill. The dry season is longer than ever as wildfires ravage forests and communities. It’s a bleak outlook for the state of the Sierra Nevada snowpack, not to mention our planet as a whole.
Deep uncertainty looms over the Colorado River and the 40 million people who depend on it for their water supply as the basin enters a critical year that could determine its future stability. Plagued by decades of overuse and human-caused climate change, demand for the river’s water has vastly outpaced its supply.
NPR’s Ari Shapiro talks with Andrew Schwartz of the UC Berkeley Central Sierra Snow Lab about how record snowfall in western states could mean a less drought-ridden 2023.
A series of storms bringing much needed rain to the San Diego region is also a reminder for residents and businesses to turn off irrigation systems when wet weather is predicted and for at least a week after significant rainfall.
While a series of atmospheric rivers is boosting Sierra snowpack and easing dry conditions statewide, there is still a long way to go to overcome three extremely dry years. Water-saving actions today can help conserve more of our most precious natural resource for when it’s needed most.
The atmospheric river currently impacting the West Coast, while creating dangerous weather conditions for millions of people, could possibly have a chance of temporarily reversing drought conditions in states that desperately need water, experts say. The National Oceanic and Atmospheric Administration describes atmospheric rivers as “rivers in the sky” because they’re somewhat long and narrow regions in the atmosphere that send most of the water vapor outside the tropics.
It was a mostly dry day Wednesday in San Diego, but another storm is on the way that could dampen New Year’s Eve celebrations. “Precipitation is over for most of San Diego County for the next couple days except for really light rain in spots until Saturday afternoon,” said National Weather Service forecaster Brian Adams, who added the storm Tuesday night dropped a half-inch to an inch of rain over much of the county.
