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.
California made historic investments in climate measures this year, as state leaders warned of current and escalating climate risks. “We’re dealing with such extremes that all our modeling, even updated modeling, needs to be thrown out,” said Gov. Gavin Newsom when he signed more than 40 bills to fight climate change in September. “The hots are just so much hotter. The dries are so much drier.”
A dry Southern California is soaking up rain from a series of storms that has, so far, brought a half-inch to more than an inch of rain to parts of San Diego County. The first storm reached the northern parts of the county Tuesday evening and swept southeast overnight before making its way south by Wednesday morning. A few lingering clouds could bring the occasional shower through the work-week but it’s not likely to be much, NBC 7 Meteorologist Sheena Parveen said.
The Department of the Interior announced $84.7 million in funding for 36 drought resiliency projects in the West. The investment supports the development of innovative drought resilience efforts, such as groundwater storage, rainwater harvesting, aquifer recharge, water reuse, ion exchange treatment, and other methods to stretch existing water supplies.
North Bay farmers, fire agencies and other water stakeholders prepare to enter a new year hoping to avoid a “Groundhog Day” movie-like repeat of events akin to 2022’s. 2022 ended much like 2021, with downpours creating a sense of optimism of more consistent rain. However, if early 2023 weather patterns mimic 2022’s, the fear exists that the North Bay will see more drought in the coming years.
