Marginally cooler weather was predicted Sunday for San Diego County, with an expansive shield of high clouds, the National Weather Service said.
The marine layer should be sufficient to generate some sprinkles across the coastal basin Monday night into early Tuesday, and possibly again Tuesday night, with minimal accumulations expected, the NWS said.
Lack of monsoon rainfall last summer and spotty snowfall this winter combined to worsen the Western drought dramatically in the past year, and spring snowmelt won’t bring much relief. Critical April 1 measurements of snow accumulations from mountain ranges across the region show that most streams and rivers will once again flow well below average levels this year, stressing ecosystems and farms and depleting key reservoirs that are already at dangerously low levels.
As drought deepens in the West and the water used by farms and people alike dwindles, farmers in Arizona and California are bracing for cutbacks in the two major federal systems that supply irrigation and drinking water to millions of people.
Water storage is shrinking with no snowpack to replenish reservoirs managed by the Bureau of Reclamation in California and Arizona. Shasta Lake in northern California is about half full while lakes Mead and Powell, the two giant reservoirs designed to contain more than 50-million-acre feet of water behind Hoover and Glen Canyon dams, respectively, are precariously low with under 20-million-acre feet of total storage combined.
California remains far behind its targets for addressing exposed playa around the Salton Sea, according to data released in the 2021 Salton Sea Management Program annual report. But state officials expressed optimism in a public workshop that they are finally beginning to catch up to those goals.
The state was supposed to implement dust suppression projects or build wetlands habitat across 3,500 acres of exposed playa by the end of 2020 to tamp down dust that’s imbued with a century’s worth of salts, pesticides and other agricultural runoff. Only 755 acres around the mouth of the New River had been completed in that timeframe, although 2020 represented the first year that any state-led dust mitigation projects was finished at the lake.
La Niña, the cooling of the equatorial Pacific that shifts weather patterns the world over, is fading away. But California may still be prone to dryness, and the U.S. Gulf Coast faces the risk of another busy hurricane season. Water temperatures in the Pacific Ocean will likely return to normal in the next few months, the U.S. Climate Prediction Center said in a report Thursday.
Ventura County has moved into severe drought conditions as it wraps up what is typically the rainiest months of the year.
The Central Valley has reached a critical juncture.
On one path, without proactive, collaborative planning, the Valley could become a haphazard patchwork of dusty fields infested with invasive weeds and pests, further impairing already poor air quality, devastating the agricultural economy and putting many farmworkers out of work.
On another path, the Valley can remain a thriving agricultural region amid a mosaic of new land uses, like vibrant habitat corridors for the endangered San Joaquin kit fox or wildlife-friendly groundwater recharge areas for migratory birds or outdoor recreational green spaces for families.
Representatives from three potable reuse projects currently under development in San Diego County will participate in the inaugural “Sustainable Building Week San Diego” at 11 a.m. on Tuesday, April 13.
Hosted by the San Diego Green Building Council, Sustainable Building Week offers free virtual events from April 12 – 16 addressing sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building. All events are free and open to the public.
Scientists have been predicting for years that the Colorado River would continue to deplete due to global warming and increased water demands, but according to new studies it’s looking worse than they thought.
That worries rancher Marsha Daughenbaugh, 68, of Steamboat Springs, who relies on the water from the Colorado River to grow feed for her cattle.
With California in drought conditions amid the third-driest precipitation totals in state history, Valley lawmakers want Gov. Gavin Newsom to take immediate action.
On Wednesday, a bipartisan group asked Newsom to declare a statewide water emergency. The governor’s office responded by saying Newsom will take action “if it becomes necessary.”
