Powerful swells from Pacific storms have caused havoc on the California coast, with a rogue wave in Pierpont, Ventura injuring eight people and causing widespread flooding. The wave, which overran beaches and flooded streets, led to authorities closing beaches, piers, and harbours until 31 December. Onlookers watched as bulldozers erected giant sand berms to shield beachfront properties. The National Weather Service warns of additional waves up to 25 feet high this weekend, stating that it is an exceptional high-surf and coastal flooding event not seen in many years.
