Death toll in California storms hits 17 and ‘likely to grow’, says state’s governor


At least 17 people have been killed in California as a relentless string of storms batter the state, turning rivers into gushing flood zones and forcing thousands of people to evacuate from towns with histories of deadly mudslides.

A catastrophic barrage of storms has caused destruction since late December, with the latest hitting in recent days and more storms on the horizon. Heavy rainfall and winds continued on Tuesday, putting entire communities under flood warnings and evacuation orders, knocking out power to tens of thousands and causing hillsides to collapse.

The entire seaside community of Montecito – home to Prince Harry, Oprah Winfrey and other celebrities – was ordered to flee on the fifth anniversary of a mudslide that killed 23 people and destroyed more than 100 homes in the coastal enclave.

State officials confirmed the official death toll in a briefing on Tuesday afternoon with the state’s governor, Gavin Newsom, saying that figure was “likely to grow”. A five-year-old was still missing after being swept away by floodwaters in Paso Robles, Newsom said, asking state residents to “just pray for a miracle” that the child be found alive.

The boy was driving with his mother when their truck became stranded near Paso Robles. A roughly seven-hour search for the missing boy turned up only his shoe before it was called off as water levels were too dangerous for divers, officials said.

Tens of thousands of California residents were under evacuation orders on Tuesday, Newsom said, and more than 100,000 were without power.

At least 17 people have died from storms that began late last month, said Wade Crowfoot, the California natural resources secretary. The deaths included a pickup truck driver and motorcyclist killed on Tuesday morning when a eucalyptus tree fell on them on Highway 99 in the San Joaquin Valley near Visalia, the California highway patrol said.

Elsewhere, a woman died after her vehicle was caught in floodwater in San Luis Obispo on Monday, according to local media reports.

What’s causing the California deluge?

A short glossary of the storms and their elements lashing the state, and how the weather wound up unleashing torrential rain on the previously parched region.

Atmospheric river 
Atmospheric rivers are long streams of moisture, defined by the National Oceanic and Atmospheric Administration as “rivers in the sky“. They transport water vapor from the tropics, after warm water evaporates off the Pacific. Moving with weather systems, ARs carry enough water to rival the average flow at the mouth of the mighty Mississippi River, and can unleash that water wherever they make landfall.

ARs are an incredibly important part of California’s climate, delivering roughly half of the state’s annual precipitation. But they can also be incredibly destructive, often accompanied by strong winds. Rated on a scale of one to five, lighter ARs from one to three are considered more beneficial, filling reservoirs and replenishing desiccated landscapes. Gabrielle Canon

Bomb cyclone Bomb cyclones are low-pressure storm systems that help create atmospheric rivers, eg long streams of moisture in the air. Unlike hurricanes or other storms that are strongest at their center, bomb cyclones can generate the worst weather at their edges.

Bomb cyclones are borne out of “bombogenesis,” a term meteorologists use to measure drops in pressure (that correlate with strengthening) at different latitudes. Bombogenesis occurs when warm air and cold air collide. These so-called “extra-tropical cyclones” can form atmospheric rivers, but they can also be boosted by them.

“It is like a feedback loop,” said Dr Marty Ralph, the director of the Center for Western Weather and Water Extremes and a researcher at Scripps Institution of Oceanography. “When you have an AR already present, the AR can supercharge the new cyclone, which can then strengthen the AR.” These two types of systems have come together to create the series of storms hitting California over the last few weeks. Gabrielle Canon

In Sacramento, the state capital, local residents and family members were mourning the deaths of two unhoused people who were killed over the weekend when trees fell onto the tents where they were sleeping in. Relatives and friends said their deaths highlighted the needs for thousands of more beds in local warming centers to protect unhoused residents during the coming storms, the Sacramento Bee reported.

The latest storm, which began on Monday, dumped more than a foot of rain at higher elevations in central and southern California and buried Sierra Nevada ski resorts in more than 5ft (1.5 meters) of snow. Rockfalls and mudslides shut down roads, and gushing runoff turned sections of freeways into waterways.

This week’s storm has unleashed havoc up and down the state. In Santa Barbara, where schools and public transit systems were shut down in response to the intense weather, a local news station interviewed a man kayaking down a city block.

In Los Angeles, a sinkhole swallowed two cars in the Chatsworth area on Monday night. Two people escaped by themselves and firefighters rescued two others who had minor injuries, authorities said. Union Station, a key transportation hub in downtown LA, was inundated with floodwater following downpours on Tuesday.

In the San Francisco Bay Area, sewers and sewage treatment plants have been overwhelmed by rain, prompting a local officials to warn: “Don’t jump in puddles. Especially in San Francisco – you want to be careful that there (could be) sewage in that,” the San Francisco Chronicle reported.

Nearly 250 trees have also toppled across San Francisco as a result of the storms, the Chronicle reported. Residents of the small town of Planada, a community of 4,000 people in central California, started their Tuesday morning with an order to evacuate their homes from the county sheriff’s office, which said deputies “are going door to door to help residents evacuate”.

After a brief respite, another storm was expected to barrel into the state beginning on Wednesday, adding to the misery and further saturating areas already at risk of flooding and debris flows.

“We’re not out of the woods,” Newsom warned Tuesday afternoon. “We expect these storms to continue at least through the 18th of this month. We expect a minimum three more of these atmospheric rivers.”

Joe Biden issued an emergency declaration on Monday to support storm response and relief efforts in more than a dozen counties. Much of California remains in severe to extreme drought, though the storms have helped fill depleted reservoirs.

The latest atmospheric river – a long plume of moisture stretching out into the Pacific that can drop staggering amounts of rain and snow – began easing in some areas. But flooding and mudslides could follow, even during a brief respite, because the ground remains saturated.

More rain was forecast to arrive Wednesday in northern California, and then a longer storm system was predicted to last from Friday until Tuesday.

In Montecito, Jamie McLeod’s property was under evacuation orders, but she said there was no way for her to “get off the mountain” with a rushing creek on one side and a mudslide on the other. The 60-year-old owner of the Santa Barbara Bird Sanctuary said one of her employees came to make a weekly food delivery and also became stuck.

McLeod said she feels fortunate because her home sits on high ground and the power is still on. But she tires of the frequent evacuation orders since the huge wildfire followed by the deadly landslide five years ago.

“It is not easy to relocate,” McLeod said. “I totally love it, except in catastrophe.”
