California’s eighth and ninth storms since Christmas to hit this weekend, adding to flood fears

Don’t be fooled by Thursday’s lull.

The eighth and ninth storms to target California since Christmas are on the way this holiday weekend, making for volatile and treacherous conditions from the Bay Area to the Sierra.

The storms themselves won’t be as intense as those that devastated communities in the Santa Cruz mountains and along the beaches over the past week, but with rivers running high and soils already saturated, more flooding and mudslides are predicted across California. The Salinas River in southern Monterey County in particular is expected to flood Friday.

“We definitely appreciate the bounty, but we wish it was spread out over a longer period,” Jeff Lorber, meteorologist with the National Weather Service, said Wednesday.

So much snow has fallen already this season that sensors are registering what is considered the “full seasonal snowpack” normally expected by April 1, state climatologist Michael Anderson told reporters during a news briefing Wednesday. It’s still too soon to say whether the snowpack levels will hold until then, but if they do, they could provide ample snowmelt to continue to fill the reservoirs this spring and summer.

Kevin “Coop” Cooper, a longtime Tahoe area ski condition reporter and resort marketing consultant, said the abundant snow is a welcome change after several lean snow years during the state’s drought.

“Right now, I’m looking out of my house and it’s snowing lightly. We’re seeing a nice new amount of snow, temperatures are dropping,” he said Wednesday. “After my 30 years up here, this is one of the best MLK weekends we’ve seen in a long time.”

But that comes with a catch.

With heavy snow and high winds predicted in the Sierra through the weekend, getting to the mountains could be dangerous. Travel in vulnerable areas, especially the Sierra, is not advised from Friday afternoon through Saturday, Lorber said, “when the winds and the rainfall will be at their peak.” The ninth storm is expected to roar in late Sunday through Tuesday.

It’s the kind of warning that weekend warriors amped to hit the Sierra slopes don’t like to heed.

“Fresh snow is like going through butter,” said Andrew Pham, 22, who stopped at Helm of Sun Valley ski shop in San Jose to attach bindings to his new snowboard and is planning to drive up Friday. “When you’re the first one on it, ooh.”

By Wednesday, snowpack levels reached 226% of average for this time of year, beating out 2005 which was 206% of average. All that fresh snow is giving experts reason to feel optimistic that drought conditions that have gripped the Golden State for three years could meaningfully ease by the end of the snowy season.

“The fact that we’re continuing to get this precipitation is just absolutely fantastic,” said Andrew Schwartz, lead scientist at the UC Berkeley Central Sierra Snow Laboratory near Donner Summit. “It’s still unlikely that we’re going to get completely out of this drought in a single year. But if the storm door stays open… we can put a serious dent in it.”

As of Wednesday, major Northern California reservoirs have registered “impressive gains,” Anderson, the state climatologist, said. But there’s still plenty of catching up to do. Lake Don Pedro east of Modesto is at 69% capacity, for instance, and San Luis Reservoir southeast of the Bay Area, which has risen 35 feet since Dec. 1, is 40% full. The Shasta and Oroville reservoirs, the behemoths of California’s water system, are at 42% and 47% respectively. Lake Oroville has risen more than 90 feet since Dec. 1, surpassing its 2021 and 2022 levels.

“We’ve had quite a deficit because of the drought,” said Molly White, principal engineer with the state water board. “So we’re seeing steep inclines right now in storage, and hope that continues.”

In the Bay Area, Mount Umunhum in Santa Cruz County registered the highest rainfall total in the 24 hours leading to 10 a.m. Wednesday — 1.03 inches. Concord recorded 0.97 inches of rain. About six-tenths of an inch fell in Los Gatos; a quarter-inch fell at Ben Lomond, and two-tenths of an inch fell in San Jose and at the San Francisco International Airport.

In Tahoe, business is booming at ski resorts, despite struggles to keep lifts operational as a series of snow storms continues to plow through the Sierras. So much snow has accumulated in the Sierras already that ski resorts are having to keep track of avalanche risk hour-by-hour.

Mark McLaughlin, the so-called “storm king” who keeps track of Sierra conditions, said he listened to the concussive pounding Wednesday morning of cannons pelting the mountain sides of the Palisades Tahoe resort to trigger avalanches to improve safety before skiers arrive.

“I bet you I heard 20 of them this morning, 20 blasts,” McLaughlin said Wednesday.

John O’Connell, spokesman for Caltrans in the Lake Tahoe area, recommended that skiers from the Bay Area hit the road Thursday if they can, as the storm may arrive earlier Friday than initially expected. They should be prepared to put chains on their car tires unless they have four-wheel or all-wheel drive vehicles with tires designed for rain and snow. Either way, if there are chain controls due to ice and snow, vehicles should drive no faster than 30 mph, he said. And temporary road closures are possible during the snowstorms.

“We recommend people bring blankets, bottled water and snacks, have their phone charged up and a full tank of gas,” O’Connell said. “If we do have to hold traffic, you might be stuck up there in traffic that’s not moving for a little bit. We just want people to be prepared.”

Pham, who was tuning up his snowboard in San Jose on Wednesday, is still hoping to hit that fresh snow.

“But Dad called and said the storm is coming and I shouldn’t go,” he said. “So I guess I’m 50/50. But it would probably be worth it.”
