Long Beach City Health Officer Dr. Anissa Davis issued an advisory Tuesday cautioning people in Long Beach to avoid swimming areas for at least three days due to the recent rainstorm.

The advisory is standard after any significant rainfall in the city, as the rain can create unhealthy conditions due to increased runoff from storm drain outlets and rivers, which eventually reach the city’s beaches, according to the Long Beach Health Department.

Data from the National Oceanic and Atmospheric Administration shows that Long Beach received 1.36 inches of rain Saturday through Monday, bringing the total since Oct. 1 to 2.6 inches. According to the agency, that puts Long Beach’s rainfall total at 131% of what would be considered normal at this point in the season.
