SAN FRANCISCO (AP) — Across Northern California, crews worked Monday to clear streets of toppled trees and branches and to clean gutters clogged by debris carried by rainwater from a massive storm that caused flooding and rock slides, and knocked out power to hundreds of thousands.
Despite the problems, the rain and mountain snow were welcome in Northern California, which is so dry that nearly all of it is classified as either experiencing extreme or exceptional drought. The wet weather also greatly reduces the chances of additional wildfires in a region that has borne the brunt of another devastating year of blazes in the state.
When the storm arrived during the weekend, people joyfully dusted off rain boots and jackets and children stomped in puddles. Social media filled with pictures that showed windshields splattered with droplets of water and single-word posts: RAIN!!!
Earl Casaclang of San Francisco kept waiting for a break in the rain Sunday to go out and smoke a cigarette.
“It was crazy! I kept thinking it was going to stop, but it just kept going and going,” Casaclang said Monday as he headed to his job as a security guard in the Financial District. “We need it to keep raining, but hopefully not that hard.”
The National Weather Service called preliminary rainfall totals “staggering,” including 11 inches (28 centimeters) at the base of Marin County’s Mount Tamalpais and 4 inches (10 centimeters) in downtown San Francisco, the fourth-wettest day ever for the city.
“It’s been a memorable past 24 hours for the Bay Area as the long talked-about atmospheric river rolled through the region,” the local weather office said. “We literally have gone from fire/drought conditions to flooding in one storm cycle.”
Northeast of the San Francisco Bay Area, 5.44 inches (13.82 centimeters) fell on downtown Sacramento, shattering the one-day record for rainfall that had stood since 1880.
The storm was accompanied by strong winds that knocked down trees and even toppled two big rigs on the Richmond-San Rafael Bridge. Pacific Gas & Electric reported Sunday evening that 380,000 homes and businesses lost power, though most had it back Monday.
Water rose so quickly that two people and a dog needed rescuing from rising creeks in separate incidents early Monday in San Jose. San Jose Fire crews located one person clinging to a tree in the Guadalupe River at 3:30 a.m., but were unable to locate a second person. An hour later, crews rescued an individual and their dog stranded on an island in the middle of Coyote Creek.
As the storm headed south, precipitation levels fell, though a flood warning still was issued Monday afternoon for Los Angeles County.
Interstate 80, the major highway through the Sierra Nevada Mountains to Reno, Nevada, was shut down by heavy snow early Monday. In California’s Colusa and Yolo counties, state highways 16 and 20 were shut for several miles because of mudslides, the state Department of Transportation said.
The same storm system also slammed Oregon and Washington state, causing power outages that affected tens of thousands of people. Two people were killed when a tree fell on a vehicle in the greater Seattle area.
Lake Oroville, a major Northern California reservoir, saw its water levels rise 20 feet (6.10 meters) over the past week, according to the state’s Department of Water Resource. Most of the increase came between Saturday and Monday, during the height of the storm, KHSL-TV reported.
Justin Mankin, a geography professor at Dartmouth College and co-lead of the Drought Task Force at the National Oceanic and Atmospheric Administration, said the cycle of going from years-long drought to record-breaking downpours is something expected to continue due to climate change.
“While this rain is welcome, it comes with these hazards and it won’t necessarily end the drought,” Mankin said. “California still needs more precipitation, and it really needs it in high elevations and spread out over a longer time so it’s not hazardous.”
Christy Brigham, chief of resource management and science at Sequoia and Kings Canyon National Parks, said the rain was a huge relief after the Caldor Fire torched an unknown number of the giant trees in the park, along with thousands of pines and cedars.
“This amount of rainfall is what we call a season-ending event,” Brigham said. “It should end fire season and it should end our need — to a large degree — to fight this fire.”
The Caldor Fire has burned for more than two months and in early September it prompted the unprecedented evacuation of the entire city of South Lake Tahoe. Firefighters now consider it fully contained, a status that — thanks to the rain — also now applies to the Dixie Fire, the second-largest in state history at just under 1 million acres.
During the weekend, the California Highway Patrol closed a stretch of State Route 70 in Butte and Plumas counties because of multiple landslides within the massive Dixie Fire burn scar.
Cal Fire, the state firefighting agency, wasn’t ready to declare the wildfire season over or to cut staffing to winter levels. “We’d like to see some more rain coming our way before we look at reducing staffing,” spokesman Isaac Sanchez said.
Mankin said the long-term forecast for California shows drier-than-normal conditions.
“To end different aspects of the drought, you are going to need a situation where parts of California get precipitation over the next three months that’s about 200% of normal,” he said, adding that “despite this really, really insane rainfall, the winter is probably going to be drier than average.”
