Flood damaged EVs pose fire risk in Laguna Beach after storm

Emergency crews in Laguna Beach warn that floodwaters can cause delayed battery blazes in submerged vehicles. Damaged cells can ignite days or weeks later, creating serious hazards for coastal residents. The warning follows severe coastal flooding across Southern California this week.

The Laguna Beach Fire Department said saltwater corrodes lithium-ion cells in electric vehicles, hybrids, bicycles and scooters. This water contact triggers fires long after exposure ends. The risk remains even after water recedes.

Flash flood warnings covered parts of Orange, Riverside and Imperial counties. Post-Tropical Storm Rachel brought heavy flooding to the region. High ocean tides worsened street conditions.

The storm damaged coastal areas, including Long Beach, Newport Beach and Malibu. Strong waves flooded streets and battered vital community infrastructure. Several towns enacted emergency safety measures.

In Long Beach, emergency teams ordered mandatory evacuations along portions of Seaside Walk. Building inspectors deemed several damaged residences unsafe to occupy. High waters reached numerous properties.

Along the Los Angeles County coastline, a coastal flood warning remained active until 3 p.m. Sunday. Forecasters warned that tides near 8 feet and surf between 5 and 8 feet threatened beaches.

Laguna Beach emergency personnel warned that normal-looking vehicles still carry hidden ignition risks. Any saltwater touching internal battery components can spark fires. The danger is not always immediately apparent.

Fire officials urged drivers never to operate or charge flood-damaged transportation. They advise motorists to call their insurance carrier immediately. Owners should arrange professional towing to an experienced mechanic.

The safety advisory also covers smaller transport, including electric bicycles and scooters. Dangerous battery signs include smoke, hissing, popping sounds and sudden heat. Anyone seeing those signs must move away and call 911 immediately.

Officials cautioned residents against moving hazardous vehicles or extinguishing battery blazes alone. Fire departments regularly issue public safety guidance during severe coastal flooding events. Firefighters secure flooded zones and inspect electrical hazards after major storms.

Owners in Laguna Beach must let certified technicians inspect submerged equipment before use. Electric components require specialized tools to confirm proper safety.
