Huntington Beach experienced significant flooding this week due to king tides, damaging 114 structures, including six homes marked with yellow tags for safety concerns. Saltwater intrusion caused a fire in one building after it interacted with a lithium-ion battery. The flooding prompted the city to declare a state of emergency and activate emergency response measures, including deploying sandbags and water pumps. Officials warn that higher tides are expected in late November, which could lead to further flooding and damage. The coastal areas of Sunset Beach and Huntington Harbour were particularly affected, with parts of the Pacific Coast Highway closed due to flooding. This event follows recent damage from Tropical Storm Rachel, raising concerns about the upcoming El Niño storms this winter.
