The Los Angeles County Public Health Department has issued a warning advising beachgoers to avoid contact with ocean water due to potential contamination from recent rainfall. Effective until Wednesday morning, the advisory highlights risks from bacteria, chemicals, and trash carried into the ocean via street runoff, a common issue after rainstorms, particularly near storm drains, creeks, and rivers. A recent storm system brought scattered showers to Southern California, increasing the likelihood of hazardous conditions.
