Valley cities started getting a taste Monday morning of the record-breaking rains that flooded highways, caused mudslides, and cut power in the Bay Area and Northern California on Sunday.

The storm arrived later than expected, lingering over the northern region of the drought-stricken state.

The National Weather Service in Hanford said Monday afternoon that thunderstorms developing in Fresno and Madera Counties could produce lightning and hail this afternoon.

In addition, there were reports of flooding in the Fresno County foothills near the Creek Fire burn scar. A Flash Flood Warning will be in effect until 4 p.m. today.

Watch: Atmospheric River Engulfs the West Coast

The Fresno County Sheriff’s Office shared video of runoff surging in the vicinity of Camp Sierra and the Big Creek bridge on Monday.

PG&E Outages at Clovis Unified Schools

A Clovis Unified School District spokeswoman said that five schools lost power this morning, but the lights were all back on by shortly before noon.

The affected schools: Kastner Intermediate, Clark Intermediate, Sierra Vista Elementary, Tarpey Elementary, and CART.

Despite the outages, no classes were canceled as the schools relied on daylight or generators to illuminate classrooms.

Watch: Truck Flips on Its Side

More Than 5 Inches of Rain in Sacramento

Sunday’s drenching rains and strong winds accompanied the weekend arrival of an atmospheric river — a long plume of Pacific moisture.

Sacramento got 5.4 inches of rain, smashing the all-time one-day rainfall record dating to 1880, the weather service said. Interstate 80, the major highway through the Sierra to Reno, Nevada, was shut down by heavy snow early Monday.

In addition, San Francisco experienced one of its wettest days ever, with 4.2 inches of rain, according to records dating to the Gold Rush era.

“It’s been a memorable past 24 hours for the Bay Area as the long talked-about atmospheric river rolled through the region,” the Bay Area weather office said. “We literally have gone from fire/drought conditions to flooding in one storm cycle.”

Mudslides in Dixie Fire Burn Scar

In Northern California, 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.

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.

Officials said mountain areas above 8,000 feet in the Sierra Nevada could get 18 inches of snow or more from Sunday night until Monday morning.

Mammoth Mountain Wind Gust Hits 159 MPH

Mammoth Mountain notched a top wind gust of 159 mph. Lake Tahoe area ski resorts reported gusts of 141 mph at Squaw Mountain and 112 mph at Kirkwood on Sunday as the storm blasted through the region.

California’s 2021 water year, which ended Sept. 30, was the second driest on record. Some of the state’s most vital reservoirs are at record low levels.
