Atmospheric river storm set to hit California this week. What to know about the rain in SoCal
“A stronger atmospheric river is set to hit Northern California on Monday and then hit Los Angeles County on Tuesday, aiding hopes of a more definitive end to a devastating fire weather season for Southern California. The atmospheric river is expected to pack a more powerful punch in Northern California. A flood watch is in effect over a broad swath of Northern California between Monday afternoon through Wednesday morning, and heavy snow is expected for the Sierra Nevada. For Los Angeles County, what initially appeared to be one storm is now separating into two distinct storm systems, said Rose Schoenfeld, a meteorologist with the National Weather Service office in Oxnard. There will still be chances of rain from Tuesday through Friday across L.A. and Ventura counties. … ” Read more from the LA Times. | Read via Yahoo News.
‘Impressive’ atmospheric river set to deliver multiple rounds of rain to Bay Area
“Hang onto your umbrellas: An “impressive” atmospheric river is set to deliver multiple rounds of moderate to heavy rainfall across the Bay Area this week, the National Weather Service said, with minor flooding and gusts of up to 50 mph also expected to sweep through the region. A plume of moisture from the South Pacific, near the vicinity of Hawaii, has been producing steady precipitation since Friday, with scattered showers lingering across the Bay Area Sunday before the next round of heavier rain is slated to arrive by Monday morning. So far, higher elevations in the North Bay have seen 3 to 6 inches of rainfall, while inland portions of the Bay Area have seen roughly 2 to 4 inches, Joe Merchant, a meteorologist for the National Weather Service’s Bay Area office, told SFGATE. … ” Read more from SF Gate.

SoCal wildfires aftermath …
LA wildfires magnify need to rethink infrastructure
“As wildfires continue to wreak havoc on Greater Los Angeles, infrastructure experts are already considering how they can build back better, specifically by creating water management systems that will show improved performance in the face of future fires. In the past, wildfire season in California, which typically affected the region’s wildlands and development at the wildland-urban interface, ran from June through October, facilitated by dry conditions. Yet, as a result of climate change, that season is growing longer. With fires increasing in frequency and moving closer to urban areas, it’s a good time to reassess infrastructure needs. … “We’re seeing a significant increase in the number of large disaster events in Los Angeles County,” said Erik Porse, Ph.D., director of the California Institute of Water Resources. “While it’s becoming more and more clear that the conditions surrounding these fires made fighting them nearly impossible, it’s important that we start to rethink some of our systems from an engineering perspective, as well as the codes and standards we have, so we can understand the level of protection they can provide against fire events.” … ” Read more from The Source.
California should expedite rules that could have helped mitigate L.A. fires, lawmakers say
“California lawmakers are calling on the state to expedite rules that some scientists and fire officials say may have helped mitigate the damage from Los Angeles’ devastating wildfires. The idea is simple: by keeping the first 5 feet around a home clear of flammable vegetation, wooden fencing and debris, homeowners can reduce the risk of embers igniting their property — and, with that, the chances of an urban conflagration, in which flames spread from structure to structure. The California Legislature in 2020 passed a bill requiring property owners in fire-prone areas to maintain so-called ember-resistant zones around their homes. The legislation tasked the Board of Forestry and Fire Protection with writing up rules governing exactly what this should look like by Jan. 1, 2023. But the board still hasn’t done so, and doesn’t yet have a firm timeline for when they’ll be finished. … ” Read more from the LA Times. | Read via AOL News.
California lawmaker calls for changes to help keep fire hydrants working during wildfires
“Assemblymember Steve Bennett, D-Ventura, proposed legislation last week to require local districts to better prepare and protect water supplies for wildfires. The bill, introduced on Thursday, calls for Ventura County water districts in high fire risk areas to top off tanks during fire weather, provide reliable backup power for pumps and make sure areas around those tanks and pumps are hardened against flames. “After every one of these fires, one of the big questions citizens ask is why didn’t the fire hydrants operate,” Bennett said. Hydrants cannot deliver all the water needed during a wildfire when dozens are opened at the same time, but efforts should be made to keep them operating as long as possible, he said. … ” Read more from the Ventura County Star.
Horvath pushes for review of water systems in fire damaged communities
“Los Angeles County Supervisor Lindsey P. Horvath is pushing for multiple initiatives to aid recovery from the devastating 2025 wildfires, including a new county fund for immediate relief and an investigation into water system performance during the crisis. The Board of Supervisors unanimously approved a motion co-authored by Horvath and Board Chair Kathryn Barger to establish the Los Angeles County Fire Recovery Fund, allocating $32.2 million in ARPA funding to provide direct financial assistance to those affected by the fires. “These fires have devastated our communities, destroying thousands of homes, businesses, and livelihoods,” Horvath said. “The LA County Fire Recovery Fund will provide direct financial relief to homeowners, renters, workers, and small business owners, and nonprofits impacted by these disasters, ensuring they have the support they need to begin rebuilding their lives.” … ” Read more from the Santa Monica Daily Press.
Examining the environmental impacts of the LA fires
“Exacerbated by strong, dry Santa Ana winds; low humidity; dry vegetation; and a long period with scarce rainfall, to date, the recent fires in the Los Angeles area of California have resulted in at least 28 fatalities; consumed more than 40,000 acres; and damaged more than 17,000 structures. Approximately 200,000 people were ordered to evacuate, and damages from the fires are estimated to be in the billions in insured losses. “AccuWeather, which also measures the costs of weather events, now estimates total losses at between $250 billion and $275 billion, almost double what it estimated last week,” notes media company Deutsche Welle. The fires, characterized as a worst-case scenario, are predicted to have devastating impacts on the environment, both in the long and the short term. … ” Read more from EHS Advisor.
It was the big one. Just not the one L.A. was expecting.
“Dave Gomberg had been watching the wind, his concern mounting. A veteran fire weather specialist at the National Weather Service, he understood the high and low pressure systems that ginned up the infamous Santa Anas that blew periodically through Southern California. This wasn’t that. High in the upper atmosphere, powerful currents were forecast to align with the fast-moving air off the desert, threatening a rare supercharged windstorm — all this in a region that had seen less than a quarter-inch of rain over the last eight months. The National Weather Service held a conference call with Southern California fire and emergency management officials on Jan. 3, warning that a “truly historic event” was due in four days, with the possibility of fires that would spread with extraordinary speed. Even an amateur weather watcher was worried about the conditions: “Altadena, we have a problem,” he warned his followers. Yet neither days of lead time nor highly specific warnings from weather experts were enough to save Los Angeles from an inferno. … ” Read more from the New York Times.
Trump’s order to release water from dams …
Expert describes Trump-ordered Northern California water release as “dumb”
“After the tragic wildfires in Southern California, President Trump often attributed the disaster to what he said was a lack of water being sent from the northern part of the state, and vowed to fix the problem. On Friday, he posted an announcement showing a photo of a flowing river, calling it the “beautiful water flow that I just opened in California.” By executive order, he directed the Army Corps of Engineers to open the floodgates at two dams on reservoirs in Tulare County. In a statement from Washington D.C., the Corps wrote, “Consistent with the Executive Order…the US Army Corps of Engineers is releasing water from Terminus Dam at Lake Kaweah and Schafer Dam at Lake Success to ensure California has water available to respond to the wildfires.” But there are a few problems with that. … ” Read more from CBS News.

Column: What does Trump know about California’s water system? So much less than he’d ever admit
Columnist George Skelton writes, “Several years ago, after she’d been elected state Assembly speaker, I asked Karen Bass about her views on the water supply — specifically from the troubled Sacramento-San Joaquin River Delta. She was honest in her ignorance. “I’m strictly a city kid,” she replied, smiling. “Coming from L.A., we use [the water]. But we have no concept where it comes from. We get it out of a bottle or the tap.” Until last month, that is, when firefighters opened taps on hydrants in Pacific Palisades, and there wasn’t any water to douse the flames incinerating houses. The water pressure wasn’t strong enough to compete against the catastrophic wildfires fanned by hurricane-force winds. But fingers naturally were pointed at Mayor Bass. Why hadn’t she planned for this disaster? As if anyone could. … ” Read more from the LA Times.

Supervisor Chavez ‘encouraged’ by Trump’s executive action on California water
“Luis Chavez, newly sworn supervisor for Fresno County’s District 3, said Tuesday he was encouraged by President Donald Trump’s executive action on California’s water system. In a memo to the Commerce and Interior secretaries Monday, Trump directed federal agencies to “immediately restart” the work of his first administration on the environmental reviews used to determine the impact of California’s water infrastructure on threatened fish species. The goal is to route more water from the Sacramento-San Joaquin River Delta southward to the Central Valley and Southern California — a cause long championed by the region’s growers and opposed by conservationists. … “At a time when food prices have been steadily increasing, we have an opportunity to help lower food prices for our region and nation, by allowing one of the most fertile agricultural regions in the world to reach its maximum potential,” Chavez said in a statement. … ” Read more from The Business Journal.

Reclamation brings new water management guidelines to Central Valley and State Water Projects
“In December, Governor Gavin Newsom and the Biden-Harris Administration signed off on the U.S. Bureau of Reclamation’s updated framework for the State Water Project and Central Valley Project, focusing on protecting endangered fish species. According to a press release from the Bureau of Reclamation, the new plan for the Long-Term Operation of the Central Valley Project and Delta facilities of the State Water Project includes more predictable actions for endangered fish and a more reliable response to multi-year droughts. This record of decision marks the end of a four-year process to overturn the 2019 biological opinions released under the Trump administration. “The completion of new operating rules for the Central Valley Project is the cornerstone of our efforts to address record drought and changing climate conditions in California,” Reclamation Commissioner Camille Calimlim Touton said in the release. … ” Read more from Valley Ag Voice.
Separating fact from fiction in California’s ag industry
“Two hot-button issues remain at the forefront of discussions about California agriculture — labor and water. In January alone, fear and confusion on these issues came in the form of a U.S. Customs and Border Protection operation in Kern County and deadly wildfires in Los Angeles, stemming from misinformation spread across social media, activist groups, and some news outlets. Misinformation and disinformation about the agricultural industry carry significant social, political, and economic repercussions for regulators, businesses, consumers, and other stakeholders, according to a 2024 study published in the Journal of Food and Water Policy. “Misinformation in food and agriculture can manifest in various forms, such as false labeling, deceptive advertising, or misleading claims about food products,” Jamie Woodside, author of “Misinformation in U.S. Food and Agriculture: A Policy Analysis of Impacts and Recommended Solutions” stated. “Likewise, the food and agricultural sectors have been victim of the politicization of scientific issues—such as climate change—and the weaponization of information related to farming practices, agricultural products, and policies.” … ” Read more from Valley Ag Voice.
Jimmy Carter and floodplain management
“It is the tradition upon the passing of a US President for Federal employees to get a day off in mourning, and later for the President to lie in state in the Capital. Many stories about President Carter will circulate in the coming weeks, but I wanted to briefly share his connection to flood management. One April 1, 1979, President Carter signed EO 12127, which established the Federal Emergency Management Agency (FEMA). Carter recognized that the frequency of natural disasters was increasing and felt passionately that the role of government was to help those in need. The Federal Emergency Management Agency was intended to be the large vehicle to coordinate response at local, state, and Federal levels to emergencies and to address the often neglected task of recovery. FEMA was also chartered with a responsibility to mitigate natural hazards before they occurred. … ” Read more from the California Water Blog.
How much runoff comes from the West’s snowpack?
“Snow is a cornerstone of the American West’s water supply, but just how important is it to the region’s streams, rivers and reservoirs? In the popular press and academic papers, the sizable share of runoff that originates as snowmelt is often cited as a reason why the West’s snowpack is so crucial to both cities and farms, not to mention the region’s wildlife and very way of life. But when a team of researchers set out to study the question, they found a wide range of estimates cited in 27 scientific papers. They concluded that “a detailed study of the contribution of snow to the runoff over the western U.S. has not been conducted.” To clarify the connection between the snowpack and streamflow—and project how climate change is altering the relationship—the scientists used computer simulations and hydrological modeling in a 2017 paper in Geophysical Research Letters to estimate snow’s significance for runoff across the West. … ” Continue reading from the Water Desk.
After wildfires, wet storms and burn scars join forces in elevating landslide risk
“The Feather River Canyon begins just outside of Quincy, California. This corridor is home to Highway 70, one of the few year-round arteries to the many mountain communities. It is known for fishing and notable whitewater rafting, as well as steep canyon walls. The holiday season brought a series of storms to this area as part of an atmospheric river, a long, narrow plume of moisture that can stretch for thousands of miles. Think of it as a rain storm that travels along the jet stream. These events not only bring increased rainfall and provide much-needed precipitation to the American West; they also bring increased risks of landslides, especially in areas affected by wildfires. Since the 2021 Dixie Fire, there have been nearly a dozen reported landslides that have closed Highway 70 along the Feather River Canyon. These slides have ranged from small to major, closing the highway from just a few hours to days or weeks at a time. The trifecta of wildfires, topography, and heavy rainfall work effectively to dislodge the exposed rock and dirt. “When you take away the vegetation, the raindrop goes directly to the soil and that mechanical action of the raindrop on the soil can help dislodge soil particles and start moving material down slope,” said Nina Oakley, Ph.D, an applied meteorologist and climatologist for the California Geological Survey. … ” Read more from the Sierra Nevada Ally.
‘It’s a tool, it’s an ally’: Why an Indigenous-led burning group wants to change California’s relationship to fire
“Kayley Walker is no stranger to fire. It’s a force that’s painted all parts of her life — like as a kid, when she’d watch her grandfather light piles of dried sticks and brush at the family ranch. That’s a good memory for Walker, and one she counts among her first experiences with fire in an Indigenous context. But that relationship became more complex in 2017 when, as a teenager, she saw her home consumed by a blaze during the Tubbs Fire. “At that point, fire was just something to be afraid of,” Walker said. Despite that fear, she felt drawn to work with fire. She’s a tribal member of the Picayune Rancheria of the Chukchansi Indians and says the practice of cultural burning has been an important one to her Tribe for millennia. After some years, she started to explore her relationship with fire and began connecting to Indigenous practitioners. … ” Read more from Cap Radio.

Because, while falsely blaming California and its politicians for devastating fires, you never acknowledge your own culpability: You are the arsonist, and not just politically. Because half of California is yours. In fact, about 46% of the land in this state belongs to the federal government. Just 3% is managed by the state.
