On a seemingly ordinary July afternoon in Jacksonville’s Fort Caroline neighborhood, yardwork turned nearly fatal for Joshua Lehmbeck. He was struck by lightning on July 6 while working outside, survived, and was released after three days in a hospital burn unit, relatives told local reporters.
Neighbor Lisa Dunn told Action News Jax it was a sunny afternoon when the quiet was shattered by a “big sonic boom.” The homeowner later found Lehmbeck on the ground with singed clothing and hearing loss. According to Dunn, doctors were surprised he had no cardiac or internal-organ damage, even though he spent three days in the burn unit. The station’s First Alert Weather Team calculated that yardwork accounted for about 3% of U.S. lightning deaths from 2006 through 2025, a reminder of how quickly summer storms can turn dangerous.
How A Strike Can Spare The Worst Damage
Emergency medicine specialists describe a phenomenon called “flashover,” in which lightning travels over the body’s surface instead of boring straight through vital organs. As Core EM explains, flashover helps explain why burned or torn clothing and dramatic skin injuries can coexist with relatively limited internal-organ damage. Even with that bit of luck, clinicians still watch closely for disrupted heart rhythms, hearing loss, and delayed neurologic problems after a lightning strike.
What Local Responders Are Saying
Lieutenant Maxwell Ervanian with Jacksonville Beach Ocean Rescue told Action News Jax, “When the thunder roars, go indoors,” noting that lifeguards clear beaches and warn bathers as storms move in. Local officials say ducking into shelter quickly and putting yardwork or other outdoor jobs on pause at the first rumble of thunder are the simplest ways to avoid ending up in the strike zone.
Simple Safety Rules
The National Weather Service reminds people that “if you can hear thunder, you are close enough to be struck by lightning.” The agency advises heading into an enclosed building or a hard-topped vehicle and waiting 30 minutes after the last thunderclap before going back outside. For lawn crews and contractors, NWS guidance recommends monitoring radar and having an emergency plan so work can stop when storms start to build.
Lehmbeck’s family said they are grateful for his recovery and are urging neighbors to take storms seriously. As Florida’s summer storm season ramps up, local officials continue to press a simple but life saving rule: head inside at the first rumble of thunder.
