LOS ANGELES—One of the wettest storms in Southern California history unleashed at least 475 mudslides in the Los Angeles area after dumping more than half the amount of rainfall the city typically gets in a season in just two days, and officials warned Tuesday that the threat was not over yet.
“Our hillsides are already saturated. So even not-very-heavy rains could still lead to additional mudslides,” Mayor Karen Bass said during an evening news conference. “Even when the rain stops, the ground may continue to shift.”
