A flood watch is in effect for Los Angeles County mountains through Monday night, impacting the Antelope Valley, Palmdale, Acton, Mount Pinos, Mount Wilson, Lockwood Valley and Lancaster.
Video from San Dimas shows there was flooding after the area received lots of rain on Sunday evening.
Meanwhile, health officials issued a warning Saturday urging caution to anyone planning to visit Los Angeles County beaches over the weekend due to the rainfall that hit the region overnight Friday.
The Los Angeles County Department of Public Health said people should be careful of swimming, surfing, and playing in ocean waters due to possible contamination caused by storm drain discharge.
"Ocean and bay recreational waters, especially near discharging storm drains, creeks and rivers can be contaminated with bacteria, chemicals, debris, trash, and other public health hazards from city streets and mountain areas after a rain fall," the department said. "Individuals who enter the water in these areas could become ill. Rain advisories remain in effect for 72 hours after the rainfall ends."
The advisory is in effect until 10:30 a.m. Tuesday.
