The people who complained about being struck by the lightning were either in the water, or very close to it, said LAFD Battalion Chief Armando Hogan.

“I heard this crackle and there was this giant bolt of lightning shooting across the sky and the loudest thunder I’ve ever heard,” said witness Joe Doro.

Los Angeles Mayor Eric Garcetti issued a statement Sunday evening: “Amy’s and my prayers are with the victims of the lightning strike today at Venice Beach. This tragedy reminds us that we can take nothing for granted or underestimate the power of nature.”

Officials didn’t have an estimate on how many people have been affected by the power outage.

A little more than an hour earlier, a 57-year-old man was struck by lightning on Catalina Island after a mid-day thunderstorm touched off at least two brush fires.
