INCOMING STORMS

Level 5 atmospheric river to unleash flooding across drought-stricken California

After nearly a year without rain, a series of potent Pacific storms are directed at Northern California this week, potentially bringing as much as a foot of rainfall and up to three feet of snow in the Sierra Nevada.  Supercharged by a classic atmospheric river pattern, the storms could lead to flash floods and dangerous debris flows in a wide swath of the region already devastated by recent wildfires.  With each successive storm, the moisture potential increases, peaking with possibly a rare category 5 atmospheric river event on Sunday. … ”  Read more from CNN here: Level 5 atmospheric river to unleash flooding across drought-stricken California

Cw3E AR update: Multiple atmospheric rivers to bring heavy precipitation to Northern California

A series of landfalling atmospheric rivers (ARs) will impact the western US this week into early next week.  AR 4/AR 5 conditions (based on the Ralph et al. 2019 AR Scale) are expected in coastal southern Oregon in association with the first and second ARs today through Friday.  The strongest AR is forecasted to make landfall across Central and Northern California on Saturday, potentially bringing AR 4/AR 5 conditions to the San Francisco Bay Area.  Inland penetration of this AR may bring AR 2/AR 3 conditions to portions of the interior western US.  Yet another landfalling AR is forecasted to impact the US West Coast on 26–27 Oct. … ”  Read more from the Center for Western Weather & Water Extremes here: Multiple atmospheric rivers to bring heavy precipitation to Northern California

Extreme atmospheric rivers to bombard California with beneficial precipitation

California and parts of the West Coast have been dealing with extreme drought, but a waterlogged weather pattern is on the way. A series of atmospheric rivers, carrying a tremendous amount of moisture from the Pacific Ocean toward the coastline, will drench parts of the moisture-starved Golden State into early next week.  Parts of the Sierra Nevada will see more than five feet of snow, with up to ten inches of rainfall likely in the lower elevations. Mudslides, debris flows and pockets of flash flooding are possible, the rains in some places arriving after more than half a year without a drop of water. High winds are also anticipated, with some coastal and high-elevation areas seeing gusts to 60 mph. ... ”  Read more from the Washington Post here: Extreme atmospheric rivers to bombard California with beneficial precipitation

What is a ‘bomb cyclone’ or bombogenesis? One is headed to Northern California

Over the weekend and during the start of next week, Northern California can expect some storms — and a “bomb cyclone.” But what exactly does that mean?

8 feet of snow? Storm train could deal deathblow to wildfire season

A beast of a bomb cyclone will take shape just off the coast of the northwestern United States and western Canada later this week, and AccuWeather forecasters say it will rival, in some aspects, the intensity of strong hurricanes from the Atlantic this season. The powerful storm will bring dangerous and damaging impacts up and down the West Coast, but the precipitation it will deliver to parts of California, Oregon and Washington is greatly needed.  The storm will have some tropical origins. … ”  Read more from AccuWeather here: 8 feet of snow?

Top expert on California’s atmospheric rivers: ‘It can break the drought’

A moisture-rich atmospheric river is forecast to hit California on Sunday and Monday, delivering a much needed drenching of rain to a drought-plagued state at a time of year when big storms are unusual.  It’s unclear at this point where the bull’s-eye of the storm will dump the most rain, but forecasters agree it will likely be anywhere from far Northern California to Central California, with the San Francisco Bay Area being impacted. The wettest spots could see up to a foot of rain. To answer questions about what an atmospheric river is and how this storm event might unfold, we checked in with Marty Ralph, the director of the Center for Western Weather and Water Extremes with the Scripps Institution of Oceanography in San Diego who is recognized as the pioneer of research on atmospheric rivers impacting the Western United States. … ”  Read more from SF Gate here: Top expert on California’s atmospheric rivers: ‘It can break the drought’

First atmospheric storm a ‘letdown’

The first of three wet-weather systems expected to roll through the Bay Area left its mark Tuesday, and it was much less notable than National Weather Service forecasters expected it to be.  They anticipate the next two will be much more significant.  “That was a bit of a letdown,” National Weather Service meteorologist Jeff Lorber said of a storm that soaked Sonoma County but left the the rest of the Bay Area with little rain. Areas of Marin County measured four-hundredths of an inch, while downtown San Francisco had .03 inches — the most rain measured outside of Sonoma County. … ”  Read more from the Vallejo Times-Herald here: First atmospheric storm a ‘letdown’

Consortium launches new online water data platform to transform water management in the Western United States as droughts intensify

OpenET, a new online platform that uses satellites to estimate water consumed by crops and other plants, launched today, making critical data for water management widely available in 17 western states for the first time amid record drought.  OpenET fills a major information gap in water management in the West. Although water is essential to the health of our communities, wildlife and food supply, access to accurate, timely data on the amount of water used to grow food has been fragmented and often expensive, keeping it out of the hands of many farmers and decision-makers. OpenET allows users to easily view and download this important water data for the current year and previous five years at no charge. … ”  Read more from the Environmental Defense Fund here: Consortium launches new online water data platform to transform water management in the Western United States as droughts intensify

Newsom expands Calif. drought emergency

After two of nearly the driest months in California history, Gov. Gavin Newsom yesterday expanded his emergency drought declaration, directing regulators to take more aggressive steps to curtail water use.  “As the western U.S. faces a potential third year of drought, it’s critical that Californians across the state redouble our efforts to save water in every way possible,” the Democratic governor said in a statement.  Newsom’s proclamation comes as California has near record low water storage in its largest reservoirs and as residents largely failed to meet the governor’s previous call to conserve. In July, he asked Californians to cut their urban water use by 15 percent, but the state only reduced water consumption by 5 percent or less compared with 2020.  Newsom added eight counties not previously included in his drought emergency orders, including many of the state’s most populous, like Los Angeles, San Diego and San Francisco. ... ”  Read more from E&E News here: Newsom expands Calif. drought emergency

This year is one of the driest and hottest in California in records dating back to 1895.  The entire state is now in a drought emergency, farmers are being paid not to grow crops, reservoirs are going dry, salmon are dying and intense drought-fueled wildfires are destroying homes and land and lives in their path.  So what happens if relief doesn’t materialize during the upcoming wet season? … ”  Read more from The Weather Channel here: California drought: What happens next?

California just declared a drought emergency. What does that mean and how will it affect your life?

As the state experiences its second-driest year on record and Gov. Gavin Newsom declares a statewide drought emergency, some Californians may be wondering: How will this shortage impact the Sacramento region and what does it mean for our everyday lives and water supply?  The declaration comes after a summer of record-high temperatures alongside plummeting water levels in reservoirs. With his announcement, Newsom cited these factors as more reason to “redouble our efforts” toward water conservation.  Experts agree. “It sounds a little bit odd at first to have a drought declaration declared at the beginning of the rainy season,” said Jay Lund, co-director of UC Davis’ Center for Watershed Sciences. “But given the state of the reservoirs and the likelihood of the drought continuing next year, I think it’s prudent to help people get prepared.”  … ”  Read more from Capital Public Radio here: California just declared a drought emergency.

Climate change makes drought recovery tougher in U.S. West

Californians rejoiced this week when big drops of water started falling from the sky for the first time in any measurable way since the spring, an annual soaking that heralds the start of the rainy season following some of the hottest and driest months on record. But as the rain was beginning to fall on Tuesday night, Gov. Gavin Newsom did a curious thing: He issued a statewide drought emergency and gave regulators permission to enact mandatory statewide water restrictions if they choose. Newsom’s order might seem jarring, especially as forecasters predict up to 7 inches (18 centimeters) of rain could fall on parts of the Northern California mountains and Central Valley this week. But experts say it makes sense if you think of drought as something caused not by the weather, but by climate change. … ”  Continue reading from the AP via the Kansas City Star here: Climate change makes drought recovery tougher in U.S. West

If you’re having a salad for lunch today, chances are it comes from the “Salad Bowl of the World,” the lush farmland that stretches for some 90 miles across California’s Salinas Valley. Lettuce, spinach, tomatoes, broccoli, strawberries, celery, cauliflower and more grow in abundance there, a source of pride and profits for farmers who work the land.  But none of it would be possible without water, and that’s the problem. The Salinas Valley is at the epicenter of a multi-year drought that’s as bad as it has ever been. Vegetables are a commodity, and as water grows scarce, price shocks could follow. … What can be done?

California, Hoopa Valley Tribe try to save salmon and a way of life

California Department of Fish and Wildlife officials are completing an unprecedented effort to save more than 1 million Chinook salmon, a campaign that also may help preserve a way of life for a Native American tribe.  In June, salmon hatched at the Klamath River’s Iron Gate hatchery were temporarily trucked to a Trinity River hatchery in Northern California. The finger-length fish were held back from a scheduled release to the Pacific Ocean out of concern the river was too warm and too full of parasites for them to survive.  Over the past two weeks, they have been released as six-inch (150 mm) yearlings, when their natural mortality is lower and when the water is a little colder and to their liking. … ”  Read more from Reuters News here: California, Hoopa Valley Tribe try to save salmon and a way of life

Photo story: Berkeley Lab mobilizes to predict how Caldor Fire may lead to floods and land movement

The Cosumnes River watershed is representative of many in California in that it extends from the Sierra Nevada mountain range to the Central Valley, providing water and recharging aquifers for municipal and agricultural regions, but unique in that it’s one of the last major rivers without a large-scale dam, enabling the study of natural rivers flows. In 2017 Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Erica Siirila-Woodburn, a hydrologist by training, decided it would be an excellent place to study how climate extremes affect mountain water cycles. Working with colleagues, she built an advanced hydrologic model to investigate how events such as drought and wildfire would affect things like groundwater levels and streamflow.Fast forward four years, and the Caldor Fire erupted in the headwater forests of the Cosumnes River basin, growing to become the 16th largest fire in California state history. Berkeley Lab scientists mobilized quickly to collect data from the burned area. … ”  Read more from Berkeley Labs here: Berkeley Lab mobilizes to predict how Caldor Fire may lead to floods and land movement 

Wildfire scars near Tahoe could see landslides as storms approach

A spell of significant rainfall — spurred by the first atmospheric river of the season — appears on its way to the Bay Area, with downpours expected to coat most of the region through the end of the week and into the weekend. … Recent wildfires, particularly in areas around the Caldor and Dixie fires, have seen large stretches of burned vegetation, plant matter that holds the soil together, Lorber said.  “As the water falls, it carries down the dirt, and all of that comes down,” he said. “With this third system, there’s a greater potential for debris flow, so we’re going to be looking at that closely, especially the areas that have those burn scars.” … ”  Read more from the San Francisco Chronicle here: Wildfire scars near Tahoe could see landslides as storms approach

Rain unlikely to reach drought-starved reservoirs that supply Sonoma County

A series of cold fronts expected to hit the North Bay beginning late Tuesday night could drop 6-to-8 inches of precipitation in the wettest mountain areas through early next week — enough to bring an end to the fire season, forecasters said.  But as rich in water as the rain makes us feel, it doesn’t mean the drought is over. Though welcomed and beneficial, much more precipitation is needed to make even a dent in what’s needed to restore supplies, forecasters and water managers say.  The ground is so parched after two years of critically low rainfall, most of the rain will just be absorbed, leaving little, if any, to accumulate as runoff and feed into streams, rivers and reservoirs, Sonoma Water engineer Don Seymour said. … ”  Read more from the Santa Rosa Press Democrat here: Rain unlikely to reach drought-starved reservoirs that supply Sonoma County

California vineyards use owls instead of pesticides

Winemakers must pay close attention to their soil, the rain, the heat, and the sunlight. But rodents like gophers and mice can wreak havoc on a vineyard. Rather than turning to rodenticides to deter pests, graduate students at Humboldt State University in California are testing a more natural approach by using owls.  The experiment is part of a long-term research study under the direction of professor Matt Johnson of the university’s Department of Wildlife.

Turlock Irrigation District: Past 2 years the fourth driest in century

The 2020-21 water year came to an end on Sept. 30 as the sixth driest year for the Tuolumne River Watershed and the fourth driest two-year period dating back to 1897. Full natural flow for the water year was 619,099 acre-feet – only 32.4 percent of the more than 1.9 million acre-feet average for the watershed.  This is a stark contrast from just two years ago when the state declared California drought-free for the first time in nearly a decade, thanks to a surging snowpack that was 152 percent of its historical average at the time.  The new water year began on Oct. 1 and will run through Sept. 30, 2022. Turlock Irrigation District is hoping the winter is wetter than in recent years. … ” Read more from the Ceres Courier here: Turlock Irrigation District: Past 2 years the fourth driest in century

‘Strongest storm system’ in 2 years headed to Fresno area. What to expect

A Pacific weather front heading for the central San Joaquin Valley is likely to be the biggest rainfall producer in at least two years —prompting Fresno County officials to brace for problems, including mud slides where the Creek Fire burned in 2020. The front is likely to bring one to two inches of rainfall to the Valley floor, and three to five feet of snow above 10,000 feet in the Sierra Nevada. “The bottom line,” the National Weather Service forecast Wednesday, “is that this storm system could potentially be the strongest storm system to impact Central California in the past two years.” … ”  Read more from the Fresno Bee here: ‘Strongest storm system’ in 2 years headed to Fresno area.

Initial treatment fails; noxious smell in Carson now expected to linger into the weekend

The noxious smell plaguing Carson residents would dissipate by the middle of this week, Los Angeles County officials said.  But Wednesday — right about when the smell was supposed to go away — the officials revised their timeline.  Efforts to combat the odor have been hampered by low supplies of a biodegradable neutralizer. And workers initially sprayed at high tide, causing much of the neutralizer to wash away.  The odor is now expected to linger until the weekend, as residents remain under public health advisement to avoid prolonged outdoor exercise at night and in the early morning. … ”  Read more from the LA Times here:  Initial treatment fails; noxious smell in Carson now expected to linger into the weekend

Reclamation releases updated projections of Colorado River system conditions

The Bureau of Reclamation has released its October 24-Month Study and 2-year projections of major reservoir levels within the Colorado River system. These projections detail hydrologic conditions and projected operations for Colorado River system reservoirs and are used by Reclamation and water users in the basin for future water management planning.  The October projections are the first to include inflow forecasts developed by the National Oceanic and Atmospheric Administration’s (NOAA) Colorado Basin River Forecast Center (CBRFC) that incorporate updated climate conditions and data sets known as the “U.S. Climate Normals.” … As a result of this update, the median water year 2022 inflow forecast into Lake Powell decreased by 800,000 acre-feet and Reclamation’s October projections show lower Lake Powell elevations compared to the September projections. … ”  Read more from the Bureau of Reclamation here: Reclamation releases updated projections of Colorado River system conditions

Drought-stricken Southwest could experience another dry La Nina winter

Cool conditions that have developed in the Pacific Ocean are pointing to increased potential for another dry winter in the drought-stricken Southwest.  Last week, the National Oceanic and Atmospheric Administration said a La Nina system has developed and is expected to last into the spring, marking a second winter of such conditions.  The weather patterns typically created by La Nina are of no help to the parched Southwest, which needs multiple wet years to bounce back from a historically dry period that has been driven by warmer temperatures and decreased precipitation.  “And when you see a precipitation forecast like this that isn’t favorable for above-average precipitation, it highlights a low likelihood of drought recovery widespread across the Southwest,” said Andrew Hoell, a meteorologist for the climate agency. … ”  Read more from the Las Vegas Review Journal here: Drought-stricken Southwest could experience another dry La Nina winter

S&P: Falling water levels could lead to higher utility bills in western states

A rating agency is warning water shortages in western states reliant on the Colorado River could lead to rate hikes that would be unaffordable for some.  S&P Global Ratings released a report examining the effect of climate change and population growth on utilities in California, Arizona, Utah, Nevada and Colorado.  The report, which was released Monday, stressed water shortages across the region will persist and continued conservation will be crucial in staving off reductions and cost increases for consumers.  “S&P Global Ratings expects water scarcity and hydrological volatility to eventually affect nearly all the issuers in the western region served by the Colorado River,” the report said. … ”  Read more from KPVI here: S&P: Falling water levels could lead to higher utility bills in western states
