Neighbors say the street often floods when it rains.

The water was high enough to cover most of the sidewalks and made its way into some underground parking garages.

Another video showed neighbors kayaking through the flooded neighborhood streets.

According to Long Beach Public Works, there was a power outage on Saturday morning that caused a couple of Los Angeles County-maintained pumps to go offline.

Heavy rain also led to flooding on a stretch of the northbound 710 Freeway near Long Beach Boulevard on Saturday afternoon, prompting a SigAlert and traffic delays, according to the California Highway Patrol.

The flooding in two northbound lanes was reported shortly before 2 p.m. near Long Beach Boulevard, the CHP said.

A large tree fell on top of a white sedan parked in Altadena on Saturday as heavy rain moved through the region.

Video from the scene at Allen Avenue and Meadowbrook Road shows the tree crushing the car.

The tree was so large, it was blocking the entire road.

There are no reports of any injuries.

California Highway Patrol was at the scene, working to clear the roadway.

Flooding was also reported in the area of Naples Lane and Ravenna Drive in the Long Beach neighborhood of Naples.

Meanwhile, the second phase of a major storm was beginning to make its way out of Southern California on Saturday afternoon after soaking the region, though forecasters said scattered rain and possible thunderstorms were still possible later in the day.

Officials were also warning people to stay off the roads if possible since water can rise quickly and carry people away, adding that most flood deaths occur in vehicles.

"Avoid the roads, stay indoors as much as possible, and stay aware of your environment," forecasters said. "If you have to drive, allow extra time as traffic will be increased due to slippery roads, low visibility, and localized flooding. If you are near a burn scar, heed the advice of local officials as they know your area best. Reschedule and avoid outdoor activities. If you are outside and hear thunder, see lightning, experience sudden wind shifts, or a sudden increase in rain intensity, head indoors immediately and stay away from windows. Stay out of, and far away from, any streams, rivers, and canyons -- especially campers. Avoid parking near tall trees. Be ready for sudden power outages. Boaters, please stay in safe harbor. For everyone, stay tuned to your local news outlet and weather.gov for any updates."

A stretch of Topanga Canyon Boulevard remained closed between Pacific Coast Highway and Grand View Drive on Saturday after morning rain resulted in a minor rockfalls and debris flows, officials said.

Caltrans crews evaluating the highway "noted several minor debris flows as well as locations where small-to-medium-sized rocks had fallen onto the highway from slopes throughout the work zone," the agency said in a statement. "Maintenance crews were working to clear the debris."

The section of Topanga Canyon Boulevard was closed Thursday night as a precaution in anticipation of the atmospheric river storm that arrived in Southern California on Friday.

The roadway will reopen after the storms pass and crews have removed all hazards, according to Caltrans. Crews were also monitoring the recovery work zone on nearby Pacific Coast Highway, but there were no major impacts as of Saturday morning.

Motorists are encouraged to avoid unnecessary travel during this storm. If traveling, check local weather alerts before heading out and use headlights and wipers when driving through rainstorms, Caltrans said. Expect delays and never drive through moving water. Remember, standing water may be deeper than it appears.
