A powerful weekend storm that caused heavy mud flows, traffic collisions, and a rare tornado warning Saturday in Southern California was finally winding down, according to the National Weather Service.
The heavy rainfall had increased fears of possible mudslides, particularly in foothill communities affected by last month’s Colby Fire.
As of Saturday night, 1,000 homes remained under mandatory evacuation orders in Glendora, officials said.
However, mandatory evacuations were set to be lifted in the area Sunday morning, according to officials.
A mandatory evacuation order remained in effect in Azusa, according to a news release from the Azusa Police Department.
The evacuation order in Azusa was for all residents on Ridge View Drive.
While mandatory evacuations remained in effect for Glendora and Asuza Saturday evening, evacuation orders were lifted for Monrovia residents living in the Madison Fire burn area, authorities announced Saturday night. The mandatory evacuation order was downgraded to an advisory evacuation.
Elsewhere in L.A. County, rain-slicked roads contributed to a series of traffic collisions, including a head-on crash in Beverly Hills that left two people seriously injured.
The crash occurred around 2:40 am. when a driver lost control, veered into oncoming lanes, and collided with another car near the corner of Sunset Boulevard and Greenway Drive (map), according to the Beverly Hills Police Department.
The impact of the crash sent both cars onto the front lawn of a home, and forced the closure of the westbound direction of Sunset Boulevard for about five hours.
While Sunset Boulevard was eventually reopened, a number of roads were closed throughout Southern California as a result of the powerful storm.
Several stretches of Southern California freeway connectors were closed early Saturday evening because of flooding, including the 110 Freeway at the 405 Freeway in Carson — which was shut down briefly — and the southbound 710 Freeway connector to the southbound 5 Freeway connector, according to Caltrans.
Late Saturday afternoon, the Ventura County Sheriff’s Office released a statement announcing a number of closures in the area “due to hazards caused by flooding and debris from rainfall over the past several days.”
The closures included: 5th street between Las Posas Road and Pleasant Valley Road in Camarillo; McNell Road closed at fairweather crossing in Ojai; the 600 block of Arnold Road in Oxnard; and Crooked Palm Road closed between North Ventura Avenue and Highway 33 in Ventura.
Additionally, Highway 39 in Asuza remained closed, according to authorities.
Also in Azusa, the National Weather Service issued a tornado warning for the area that remained in place until 4 a.m.
The forecast called for more heavy rainfall across Southern California throughout the day, with a chance of thunderstorms, according to the National Weather Service.
The weather service also issued a flash flood warning for the recent burn areas in L.A. County. The warning expired at 6:15 p.m.
A flash flood watch remained in effect for parts of L.A. and Ventura counties until 9 p.m.
High surf was also an issue on Saturday along the Southern California coast. In Santa Barbara County, Goleta Beach was closed “due to large surf affecting the coastline,” according to a tweet from the weather service.
A high surf advisory that was issued along the coast was set to expire
The heavy rain and cold temperatures also prompted the Los Angeles Homeless Services Authority to keep winter shelters open this weekend.
“Despite the lack of fiscal resources available in our continuum, I’m extremely pleased at the efforts and cooperation of LAHSA and our dedicated service providers to extend our winter shelter services through this life-threatening situation we face with the weather this weekend,” LAHSA Chairman Larry Adamson said in an emailed statement.
As of 10 p.m. Saturday, 3.29 inches of rain had fallen in downtown Los Angeles, 3.62 in Bel Air, 4.38 inches in Pasadena and 2.75 inches in Ventura, the weather service reported.
Scattered showers were forecast to replace heavy rains in Southern California through Sunday morning, according to the weather service. The storm was expected to taper off completely by Sunday evening.
Previously, the rain had threatened to dampen Sunday’s red carpet arrivals at the Academy Awards.
