The high tides and coastal erosion are threatening homes, public infrastructure, and transportation routes in Huntington Beach and surrounding areas. Flooded roadways and damaged cliffs have led to closures on PCH and other streets, disrupting daily commutes. Electric vehicles submerged in salt water pose a fire risk, even after drying out, due to potential battery damage. Residents and visitors are advised to exercise caution, as more rain and storms are expected over the Halloween weekend, increasing the risk of further flooding and erosion.
