A string of recent weather warnings continues as county officials are cautioning beachgoers to stay away from waters close to discharging storm drains, rivers and creeks.
Rainfall this week could potentially contaminate public beaches through those discharge points.
"Bacteria, debris, trash and other public health hazards from city streets and mountain areas are likely to enter ocean waters though these outlets," according to a statement from Los Angeles County Officials.
Meanwhile, the National Weather Service also issued a high surf advisory for Los Angeles County beaches, including Malibu. The advisory expires late Thursday night.
The warning of potentially dirty water for recreational beachgoers is effective until Sat., Dec. 29 but could be extended depending on rainfall.
Despite projected rainfall earlier this week, Malibu's Thursday forecast shows dry weather and temperatures in the high 50s and low 60s.
