DANVILLE, CA — A fast building "bomb cyclone" storm system toppled power poles and cut power to 2,540 Danville residents on Sunday. Strong gusts and downpour also knocked out power for some 66,000, according to Pacific Gas & Electric.

The utility warned ahead of the storm that the massive storm would likely bring torrential rain, heavy mountain snow and intense winds, which could cause widespread outages.

As first responders worked to mitigate the damage wrought by the storm, the Danville Police Department was urging residents to avoid Eastbound Camino Tassajara at Lawrence Road due to a power pole that had fallen in the roadway, the department said.

PG&E was assessing the damage and was requiring a detour of traffic likely for the rest of the afternoon.

The storm also prompted community members to end Danville's bustling Fallfest a day early.

In nearby Pleasanton, 3,027 residents had lost power due to the torrential storm.

The North Bay remains hardest hit and as of 11:30 a.m., power was out to 43,319 customers, mostly in Marin and Sonoma counties, PG&E spokesman J.D. Guidi told Bay City News.

About 16,439 customers are affected on the Peninsula; 2,430 in San Francisco, 2,258 in the East Bay, and 1,582 in the South Bay.

The weekend's extreme "atmospheric river" was forecast to effectively end another destructive wildfire season and quell some drought concerns in Northern California, but on Sunday it brought a slew of other dangers such as flooding and mudslide risks in fire-scarred California.

Also dubbed a "bomb cyclone," the powerful storm swirled violently over the state, and had a pressure equivalent to a Category 4 hurricane, according to U.S. StormWatch. The storm was expected to dump a foot of rain in some parts of Northern California and deliver 8 feet of snow over the mountains, USA Today reported.

As the storm barreled through the Bay Area Sunday, PG&E was also warning residents not to touch or get anywhere near downed wires. Downed wires can be reported by calling 911 and PG&E directly at 1-800-743-5002.

"Never touch downed wires: If you see one, assume it is energized and extremely dangerous," PG&E tweeted on Sunday. "Do not touch or try to move it — keep children and animals away."

PG&E started staging crews on Saturday to deal with the storm, with more 3,000 workers available to respond to outages, Guidi said.

On Sunday, emergency crews responded to flooded roads, downed wires and toppled trees all over the Bay Area on Sunday.

"Water levels are on the rise in many of our creeks right now due to the storm," the Santa Rosa Fire Department wrote on Twitter. The department posted video of rushing waters of a rain-swollen waterway at Flat Rock Park, at the confluence of Brush and Santa Rosa creeks. The waterbed was mostly dry just a week ago.

"Please stay away from the edges of these fast-moving waterways," department officials tweeted.

Several homes were flooded in Santa Rosa on Sunday and authorities were urging residents not to attempt to drive through flooded streets in the city.

Evacuation warnings were issued for Santa Cruz and San Mateo counties on Sunday. In San Francisco, the threat of a large tree leaning in the city's Forest Hills neighborhood prompted fire officials to order the evacuation of three homes on Sunday morning, the San Francisco Fire Department said on social media about 11:10 a.m. Residents in the 2176-2178-2184 block of Ninth Avenue were being evacuated.

National Weather Service officials said the rains would persist into the night and were encouraging residents to stay home on Sunday and to avoid travel.

"It's a great day to stay home! Heavy rain across the area will lead to roadway flooding today into tonight," NWS officials in Sacramento tweeted. "Tonight into tomorrow night, snow will impact mountain travel. If you do have to drive, take it slow and leave plenty of time get to your destination."

Flash flood warnings were issued to several reaches of Northern California on Sunday, including where the destructive Dixie Fire left a massive burn scar. Areas where fires impacted the topography become dangerous and ripe for "debris flows" during a storm such as this weekend's bomb cyclone, authorities warned.

Debris flows tend to manifest during copious rainfall, transforming topography into a treacherous river of mud, weather experts said. These mud rivers can flow rapidly, striking with little or no warning at avalanche speeds — faster than a person can run, according to Ready.gov, a website created by the U.S. government to help citizens cope with emergencies.

Ahead of the treacherous storm, Northern Californians were urged to charge up cell phones and battery back ups, tie down outdoor furniture and trash cans. Emergency kits or "go bags" should also be prepared ahead of the story, officials said.

The storm also prompted community leaders to cancel the Alameda County Fair, one of the most popular Bay Area attractions.
