The drought-parched state of California definitely needed a soaking rain event, but all this precipitation has also had negative consequences.

Mudslides, rockslides and sinkholes have all been reported following days of rainfall across the state, leaving some streets flooded and residents in wildfire-scarred areas reaching for sandbags. While much of the event is ending, some areas are still expected to see more rain before the system leaves California.

The San Diego area was struggling with lingering rainfall Thursday morning, where some residents woke up to find flooded streets, partially-submerged cars and even reports of a mudslide or two. San Diego 6 was reporting a 60- to 80-foot-wide mudslide had occurred near the Sycuan reservation, east of San Diego, according to reporter Heather Myers.

Linda Lam , weather.com meteorologist, said the persisting rain showers should be out of San Diego by mid-morning Thursday.

Rain caused problems along the Pacific Coast Highway as early as Sunday, where rockslides were reported, but the Bay Area began seeing the heaviest precipitation on Tuesday. Street flooding was reported Tuesday morning in Mill Valley as vehicles tried to drive through the floodwaters.

Nearly six inches of rain had fallen in parts of Monterey County by midday Wednesday.

Flooded streets were also observed in parts of San Mateo, San Francisco, Alameda and Santa Clara counties Tuesday morning, according to National Weather Service storm reports. Through Wednesday afternoon, San Francisco International Airport had reported 3.71 inches of rain since Sunday, which was more than the hub recorded in all of 2013. The airport received just 3.38 inches of rain last year, according to local records.

Early Thursday, flash flooding washed out a road in Riverside County, prompting the rescue of 14 people, according to NBC Southern California. The passengers were rescued around 1:15 a.m. local time from five vehicles, which were surrounded by almost 4 feet of mud and water.

Wednesday evening, freeway flooding disrupted Sacramento's rush-hour commute, according to the Associated Press. Capital City Freeway, also known as Highway 51, experienced flooding that blocked two of its three lanes, according to the California Highway Patrol. The flooding affected lanes along Interstate 80 farther north, as well.

Another problem plagued coastal residents of Southern California, who experienced problems with trash from city streets, the Associated Press reported. Heavy rainfall washed large tangles of waste into storm drains that emptied onto beaches. Long Beach crews busily worked on cleaning the area, according to lifeguard captain Scott Dixon.

In Southern California, the town of Camarillo was experiencing minor mud flows as the rain fell Tuesday afternoon. According to the Associated Press, authorities issued a mandatory evacuation for about 75 homes in that area, but the evacuation order expired Tuesday night. Still, officials were telling residents to stay away voluntarily.

"It'll be the locusts next," evacuee Rose Martin told the Ventura County Star. "It's that mountain. You never know what it's going to do."

Another town fearful of the disastrous impacts of too much rain in a short time span is Glendora, where a January wildfire only burned 2,000 acres but left lasting impacts. With the town sitting in the shadow of hills torched by that fire, the Los Angeles Times says any rain that falls could loosen the ground in the burn scar , triggering mudslides due to the lack of vegetation that usually keeps the land from falling away.

Glendora residents like Cory Hansen piled sandbags around their homes in anticipation of the worst.

"Hundreds, hundreds of them," he told KABC-TV, speaking about the number of sandbags he'd collected to fortify his home. "We don't know what's going to happen in the next few days."

Due to the fear of heavy rain, voluntary evacuations were issued for the towns of Azusa and Glendora. Another voluntary evacuation notice was issued for about 60 homes in rural Silverado Canyon, the Associated Press noted. Silverado Canyon is located in Orange County.

"We know it's hard to leave your homes behind, but the fact of the matter is when the mountain does cut loose ... it happens so fast that you're already behind," said Steve Martin, acting Deputy Fire Chief for the Glendora Fire Department, in a press conference late Tuesday morning. "You're not going to be able to get out then and you're going to be stuck and stranded, and it's going to be very difficult for us to get to you."

Downtown Los Angeles received 1.15 inches of rain Tuesday, breaking a daily record that stood for 53 years. All that precipitation may have helped create a sinkhole that reportedly formed near West Hollywood overnight Tuesday. In the Bay Area, several additional reports of sinkholes and roof collapses trickled in Wednesday morning.

At least 10 to 15 cars were stranded Sunday along the highway after rain triggered three separate rock and mud slides, some up to three feet deep. At least one of the vehicles stuck in the slides has already been removed, according to the Ventura County Fire Department, and two occupants of vehicles stranded along the highway were able to walk away unharmed.

The slides shut down a stretch of the highway in Ventura County nearly nine miles in length, from 1.5 miles north of the Los Angeles/Ventura County border, to five miles north of Point Mugu, California, the state's Department of Transportation (CalTrans) reported. The highway reopened late Thursday afternoon, according to the Associated Press.

A spokesman for the California Department of Transportation (CalTrans) told The Weather Channel that no one was injured in any of the incidents and that a contracting company has been hired to help remove debris from the highway.

CalTrans originally hoped the highway would be cleared and opened by Tuesday, but CBS Los Angeles reports officials will likely keep it closed as a precaution with more rain in the forecast.

The burn area stretch of the Pacific Coast Highway is one of many additional challenges CalTrans crews could face in the coming days for mudslide impacted areas since more rain is expected, according to Erdman.

"Just over an inch of rain had fallen in Malibu Canyon this weekend," said weather.com senior meteorologist Jon Erdman . "That doesn't sound like much rain, but it fell over the Springs fire burn area from spring 2013. Even just a quarter to half-inch of rain an hour is enough to trigger some debris flows from burn areas."

Roughly 80 percent of the state is in extreme drought due to several abnormally dry years. NBC News reports there have been more than 5,500 wildfires in California this year, which is 1,000 fires above average.
