A light show filled the Lowcountry sky Monday night as a thunderstorm passed over, and at least one home was damaged by a lightning strike.

An estimated 1,200 lightning strikes were documented between 8 p.m. and 10 p.m., according to Vern Beaver, a meteorologist with the National Weather Service in Charleston.

Neighbors said they heard a loud boom before a fire was reported in a townhouse at 1201 Circle Oaks Drive on Daniel Island, Charleston Fire Marshal Mike Julazadeh said. Charleston and North Charleston firefighters were dispatched at 9:24 p.m. The first firefighters arrived at 9:37 p.m. to see heavy fire near the roof of the three-townhome building. The fire was largely extinguished by 10:01 p.m., Julazadeh said.

The fire started in the attic and was consistent with a lightning strike, he said.

The townhouse that caught on fire sustained fire, heat and water damage throughout, and the adjacent townhome was also damaged by the fire.

A Charleston firefighter sprained a shoulder and a North Charleston firefighter was treated on scene for heat stress, Julazadeh said.
