California was slammed by yet another atmospheric river on Sunday night, bringing heavy rains and damaging winds to areas that have already seen heavy precipitation over the past weeks.
In the face of yet more fierce storms predicted for this week that could lead to more flooding, landslides and power failures, Gov. Gavin Newsom asked President Biden to declare an emergency to help with California’s storm response. The combination of runoff from the New Year’s Eve storm and Wednesday’s bomb cyclone has saturated soils across the region, as burn scars in the Santa Cruz Mountains, North Bay highlands and coastal region south of Big Sur struggle to absorb the excess moisture.
The National Weather Service has issued a flood watch lasting through Tuesday that covers the entire Bay Area, Sacramento Valley and Monterey Bay to account for the upcoming storms. A high wind warning was issued for the Bay Area and Central Coast, from Cloverdale in northern Sonoma County to the southern Monterey County border, until 4 p.m. Monday. The entire Bay Area and Central Coast are at moderate risk of excessive rainfall Monday, the weather service said.

Santa Cruz forecast: More rain, 50 mph winds expected tonight | 11:16 a.m.
Moderate rain bands will gradually clear out by 2 p.m. this afternoon, giving a brief break for residents dealing with floodwaters from the San Lorenzo river and nearby streams that are filled to the brim. Water levels will likely continue to rise as runoff from nearby roads and Highway 17 filters into the Santa Cruz Mountains.
Another round of rain will then begin rolling in tonight after 8 p.m. This round will host isolated thunderstorms that will bring brief bursts of strong winds gusting to 50 mph and downpours between half an inch to three quarters of an inch. Because of their isolated nature, these thunderstorms will bring on-and-off rain to residents in the Santa Cruz Mountains, with dry-periods between each storm lasting anywhere from a few minutes to a couple of hours. These “garden-variety” thunderstorms will last through Tuesday morning.

Flood ravages Santa Cruz County bridge
Heavy floods caused the Via del Sol Bridge to collapse, cutting off one pathway to Browns Valley Road, a private, one-lane artery linking small neighborhoods in the Santa Cruz Mountains. As of 10:30 a.m. Monday morning crews were headed out to a backup bridge, Las Colinas, a small span over a creek that also feeds into the Browns Valley area. Last week workers cleared debris from the channel to prevent it from flooding the banks, county spokesperson Jason Hoppin said, noting that crews will resume that cleanup effort today to protect surrounding homes.

San Lorenzo River floods Santa Cruz homes and roads
Several homes and roads were under water in the Felton Grove area of the Santa Cruz Mountains as the San Lorenzo River spilled its banks Monday morning, inundated by relentless rain showers over the weekend.
Intense rains had caused the river that runs through the mountains into the city of Santa Cruz to flood earlier than anticipated. It continued to rise as of 8 a.m. Monday. Hoods of cars and the upper halves of garages peered over pools of muddy water, which had submerged trees to the point that only their branches stuck out.

Daniel Swain: Central Coast, SoCal at greatest risk of flooding today, Tuesday
Parts of southern California and the central coast will be at the greatest risk of flooding, with one or two more significant storms between now and the end of the week, said UCLA climate scientist Daniel Swain at a live office hours event Monday morning. Though the storms aren’t “extremely strong,” saturated soils mean that moderate storms can still cause significant runoff and flooding, Swain said.
The current wet spell is “remarkable in its intensity, but certainly not the most extreme we’ve seen historically,” Swain said. California is susceptible to occasional but severe flood events, Swain said.
“In this drought era, a lot of folks in California may have forgotten just how significant the storms can get at times, how much water can fall from the sky over a relatively short period of time,” Swain said.
It can be difficult to talk about the risk of severe flooding in the midst of severe drought, Swain said. But there is potential to “fight droughts with floods” such as by redirecting some of these flood flows as they occasionally occur to recharge depleted Central Valley groundwater,” Swain said.
Swain and co-researcher Xingying Huang have found that climate change is increasing the risk of a California megaflood, what they’ve dubbed “Arkstorm 2.0.” But the current storm, though severe, “is not at the top end of the range of what is plausible in this part of the world, especially in a warming climate,” Swain said Monday.
“This is neither as intense nor as long in duration nor as widespread as the kind of events that we are talking about, although it certainly gives us a taste of what things (could) look like as we head a little bit more in that direction,” Swain said.
Pajaro Valley Unified School District schools closed Monday
All Pajaro Valley Unified School District schools in Santa Cruz County are closed Monday due to a flash flood watch, according to a notice from the Watsonville district.

Northern California forecast: After brief lull, rain resumes Tuesday
Heavy downpours are set to persist through 10 a.m. in the South Bay and Santa Cruz Mountains as the atmospheric river dips south into the Central Coast. This system will continue its march into the Big Sur coast this afternoon, giving a chance for Bay Area residents to pick up from wind damage last night and for water levels to stabilize in rivers and streams in the region.
This includes the high water levels in the Santa Cruz Mountains, where extreme flooding from high rainfall rates overnight caused the San Lorenzo River.
More heavy rain will arrive to the Bay Area after midnight and into early Tuesday morning. raising the risk for moderate downpours and additional strains on burn scars and rivers in the region that are already filled to the brim with water. These rain bands will persist through late Tuesday morning and hang over the Santa Cruz Mountains until the early afternoon hours before finally exiting Northern California and the Central Coast by mid-afternoon.

Slight risk for Northern California tornadoes as atmospheric river heads south
Episodic bursts of isolated thunderstorms be possible on the coast from the Peninsula into Monterey Bay this morning, with instability raising the risk for isolated landspouts and weak tornadoes. The high energy off this storm’s strong winds and instability will remain mostly off the coast as it dips south into Monterey Bay and the Big Sur Coast this afternoon, but that will translate into a slight risk for waterspouts that could briefly come ashore. This risk will drop off on the Peninsula by the early afternoon and clear out by Monday night on the Central Coast.

FEMA approves California disaster aid
President Biden has approved federal disaster assistance for California, the Federal Emergency Management Agency announced Monday. Gov. Gavin Newsom had requested the aid Sunday, saying an emergency declaration would unlock the “full support of the federal government” for the state as it faces major storms this week bringing more flooding, landslides and power failures after last week’s deadly bomb cyclone deluge. The aid will supplement state, local and tribal response efforts to emergency conditions resulting from the winter storms, flooding and mudslides starting Jan. 8 and going forward, FEMA officials said in a news release.
FEMA is authorized to coordinate disaster relief and prevention efforts in El Dorado, Los Angeles, Mariposa, Mendocino, Merced, Monterey, Napa, Placer, Riverside, Sacramento, San Bernardino, San Mateo, Santa Clara, Santa Cruz, Sonoma, Stanislaus and Ventura counties.

What’s the difference between an atmospheric river and a bomb cyclone?
An atmospheric river is a band of moisture that transports large amounts of water through the atmosphere, producing heavy rain and snow. A bomb cyclone is a storm that rapidly intensifies over a 24-hour period and can produce strong winds, intense rain and snowfall. Such a storm made landfall last week. The current system is an atmospheric river storm, which being propelled by an extensive plume of sub-tropical moisture streaming in from the Pacific.
