A continuing influx of sewage-tainted flows from the Tijuana River prompted health officials on Thursday to extend an ocean-pollution warning north to the Silver Strand.
Rain-driven contamination has been entering the surf in the far southern reaches of San Diego since the middle of last month, leading to off-and-on beach closures just north of the international line, according to the county Department of Environmental Health.
On Wednesday, the DEH issued a pollution advisory from the border to the southern reaches of Imperial Beach following a spill of roughly two million gallons of sewage that had entered the Tijuana River in Baja California.
Since then, observations have suggested that northward ocean currents had pushed the contamination as far as the southern reaches of Coronado, according to the county agency.
Signs warning of the hazard will stand in the affected areas until testing deems them safe for human contact.
