Moderate to heavy rain fell on the Southland early Thursday, triggering rock and mud slides that blocked a key roadway near Malibu and caused minor roadway flooding and debris flows in other areas, including Burbank.
A mudslide trapped several vehicles and forced the closure of a section of Topanga Canyon Boulevard in Topanga near Malibu. The mudslide was reported around 1:45 a.m. and affected Topanga Canyon Boulevard between Pacific Coast Highway and Grand View Drive — a stretch that could remain blocked through the weekend as crews work to clear the roadway.
About four to five vehicles were stuck in mud and drivers had to be rescued, but there were no reports of any injuries.
In Burbank, overnight rains triggered some minor mud and debris flows in hillside areas below the recent La Tuna Fire burn area. Walnut Avenue was closed for a time at Sunset Canyon, and mud and water flowed briefly along Country Club Drive. But all streets in that area were reopened by mid-morning.
In La Crescenta, a spotter reported heavy rain overnight, with almost an inch of rain in just over a half hour, according to the National Weather Service.
“There have been plenty of minor flooding reports on freeways and low-lying roadways across a wide portion of L.A. County early this morning,” according to a morning alert from the NWS. “The heaviest rain was occurring across the eastern half of the county, with a few heavy showers still moving across the western San Fernando Valley and West Los Angeles.”
The showers tapered off by late morning, but forecasters warned that more rain is on the way.
“A storm will arrive by early Friday and bring precipitation into early Saturday,” according to the NWS. “Then a brief break early next week before another storm is forecast to arrive by early Wednesday, and bring possible precipitation into Thursday.”
In the mountains, snow levels fell to between 4500 and 5000 feet overnight. Light snow accumulations are also possible in the mountains Friday into Saturday morning, creating hazardous driving conditions, according to the NWS.
The NWS forecast mostly cloudy skies in L.A. County Thursday and highs of 46 degrees on Mount Wilson; 56 in Palmdale and Lancaster; 60 in Avalon and Saugus; 62 in Burbank and at LAX; 63 in Long Beach and Pasadena; and 64 in Downtown L.A. and Woodland Hills. Friday’s highs will be about the same but amid rain resulting from what’s expected to be the strongest of the storms that have hit the Southland this week. As of Thursday morning, an extended forecast projects no rain until Wednesday.
Partly cloudy skies were forecast in Orange County amid temperatures virtually as low in inland Orange County as along the coast, which is unusual. The NWS forecast highs of 59 in San Clemente; 62 in Newport Beach and Mission Viejo; 63 in Laguna Beach; 64 in Yorba Linda and Irvine; and 65 in Fullerton and Anaheim. About the same temperatures will prevail Friday amid showers.
