Record rainfall doused Southern California on Christmas Eve, forcing evacuations and leaving some residents in need of rescue amid rising waters.
"At least dozens" of people were rescued overnight amid flooding and mudslides in Wrightwood, California, a community nestled in the San Gabriel Mountains, northeast of Los Angeles, said Christopher Prater, a public information officer for the San Bernardino County Fire Department.
There were no reported deaths in the area, but one child had to be taken to the hospital for a minor injury, Prater said.
More than 120 emergency responders worked overnight to rescue people and perform damage assessments, Prater said. Video shared by the county showed mud and floodwatersrushing past cabins in a pine forest.
"It was pretty dynamic," Prater said on Thursday, adding that officials were still tallying up the number of people rescued. "We still have crews out there. They're providing life-safety first and trying to divert the water and mud and debris flows as best we can to help properties."
