With multiple powerful storms continuing to bear down on California, state officials have warned that rural areas are the most at risk of flooding because the levees that protect them aren’t built to the same standards as others that shield more populated cities.

These rural levees – many of which are owned and maintained by private land owners – mostly protect farmland from flooding and pose minimal risk to most homes. But failures can cause major thoroughfares to flood, as happened on New Year’s Eve when a major highway in Sacramento County flooded and one person was killed.

The main highway from Los Angeles to Phoenix was damaged by a flash flood that washed out part of the road through the Southern California desert in the latest bout of punishing monsoonal thunderstorms that have hit the region this summer.

The newest round of flooding started Wednesday evening, damaging a roadway that was part of a detour past a repair project along eastbound Interstate 10 near the small community of Desert Center, about 165 miles east of Los Angeles.

Traffic in both directions was halted initially, but westbound lanes for motorists heading from Arizona to California reopened later.

Between vast almond orchards and dairy pastures in the heart of California’s farm country sits a property being redesigned to look like it did 150 years ago, before levees restricted the flow of rivers that weave across the landscape.

The 2,100 acres at the confluence of the Tuolumne and San Joaquin rivers in the state’s Central Valley are being reverted to a floodplain. That means when heavy rains cause the rivers to go over their banks, water will run onto the land, allowing traditional ecosystems to flourish and lowering flood risk downstream.

(TNS) - Margaret Mangan didn’t sleep well in the weeks following the Ridgecrest, Calif., earthquakes. The July shaking triggered a swarm of smaller tremors in the nearby Coso Volcanic Field, a cluster of lava domes and cinder cones at the northern end of the Mojave Desert. And it was Mangan’s job to watch for a possible eruption.

“We were pretty much on 24-7 vigilance,” said Mangan, the longtime scientist-in-charge of the U.S. Geological Survey’s California Volcano Observatory.

(TNS) - Oroville Dam’s massive flood-control spillway will be deployed Tuesday for the first time since it was rebuilt for $1.1 billion after a near-catastrophe forced the evacuation of 188,000 people in 2017.

In a brief statement Sunday, the California Department of Water Resources’ deputy director Joel Ledesma said the agency has “restored full functionality to the Oroville main spillway and is operating the reservoir to ensure public safety of those downstream. The Oroville main spillway was designed and constructed using 21st century engineering practices and under the oversight and guidance from state and federal regulators and independent experts.”

(TNS) - In the most extensive study to date on sea level rise in California, researchers say damage by the end of the century could be far more devastating than the worst earthquakes and wildfires in state history.

A team of U.S. Geological Survey scientists concluded that even a modest amount of sea level rise — often dismissed as a creeping, slow-moving disaster — could overwhelm communities when a storm hits at the same time.

The study combines sea level rise and storms for the first time, as well as wave action, cliff erosion, beach loss and other coastal threats across California. These factors have been studied extensively but rarely together in the same model.

(TNS) — The strongest and potentially wettest storm of the winter season is bearing down on Southern California this week, threatening to unleash debris flows in burn areas in Orange and Riverside counties as the region’s wild winter continues.

The atmospheric river-fueled storm, packed with subtropical moisture, will take aim at large swaths of the already-soaked state beginning early Wednesday and lasting through Thursday.

(TNS) - A storm over Southern California dumped rain and snow on the area Monday, heightening the threat of mud and debris flows in areas scarred by recent wildfires, prompting evacuation orders, and closing a stretch of Pacific Coast Highway in Malibu and the Grapevine section of the 5 Freeway.

The National Weather Service issued a flood advisory for western Los Angeles County and Ventura County, warning that roads, streams and highways could pool with rain as showers are expected through the week.

As rain pelted the state Monday, setting new rainfall records in Burbank and Sandberg, a town near the Grapevine, officials began to close roads that were too dangerous for traffic.

(TNS) - Brent Larson awoke at 4 a.m. to the shake and rumble of what felt like a freight train rolling down the hill toward his Santa Barbara County home.

He leaped from his bed and woke his two sons. In seconds, a wall of water, mud and rock slammed into his house, smashing through one window, then the next, then a third, pouring in as the trio sprinted to the safety of the chimney at the home’s far corner.

“It was like out of ‘Indiana Jones,’” he said, nine months later, still shaken.

In the wake of hurricanes Florence and Michael and myriad other devastating storms and wildfires stacking up during the last decade, an updated assessment of California’s changing climate offers the projection of more of the same.

The assessment said Californians can expect more heat and more extreme weather, which would lead to more wildfires, floods, drought and public health issues. California’s Fourth Climate Change Assessment was produced as part of a volunteer initiative by climate experts. The assessment updates the third one issued in 2012.
