People who visit beaches in Los Angeles County were urged Saturday to avoid contact with the water through the holiday weekend due to the potential for higher bacteria levels from runoff from the week's rainstorms.
The Los Angeles County Department of Public Health said the beach contamination from bacteria, chemicals, debris, trash and other public health hazards could persist through Monday night, especially near storm drains, creeks and rivers.
Rain advisories remain in effect 72 hours after rainfall ends, officials said.

In addition, the area of coastline from Victory Beach to Goff Island Beach in Laguna Beach is closed to swimmers, surfers and divers due to a sewage spill.
