Southern California recently faced significant coastal flooding due to Tropical Storm Rachel’s impact. This has led fire officials to highlight the risks associated with saltwater exposure and electric vehicles. Saltwater can damage lithium-ion batteries in electric cars, hybrids, e-bikes, and scooters, potentially causing fires long after initial exposure.
On Saturday, October 10, 2026, powerful waves and high tides struck areas such as Long Beach as the storm approached, prompting emergency measures. Homes in Long Beach, Newport Beach, and Malibu experienced widespread flooding and infrastructure damage. Residents from certain areas in Long Beach, deemed unsafe, were ordered to evacuate.
Coastal flood warnings were in place until Sunday afternoon, cautioning of tides up to 8 feet and surf between 5 to 8 feet. These could cause further flooding and beach erosion.
The Laguna Beach Fire Department warns that even vehicles appearing undamaged could become fire hazards if batteries or electrical components were exposed to floodwater. They advise against driving or charging potentially affected vehicles. Residents should contact insurance providers, arrange for professional towing, and ensure inspection by certified mechanics.
Similar warnings apply to electric bicycles and scooters that might have encountered floodwaters. Indications of battery danger include smoke, hissing or popping sounds, and unusual heat. In such cases, residents should avoid the vehicle and call emergency services immediately.
Officials stress that battery fires can occur much later than the initial saltwater exposure. They advise against attempting to move or extinguish a vehicle showing these warning signs, reiterating the importance of caution.
