GWINNETT COUNTY, Ga. -- A 90-year-old woman managed to escape house fire thought to have been caused by lightning Wednesday in Gwinnett County.

The family said they've lived at the home on Trailblazer Way in Lilburn for more than 20 years. They said they were having coffee when they heard an explosion, but had no idea that their home was on fire until they began smelling smoke about 20 minutes later.

"We went outside and looked, and that's when we noticed the ceiling -- the roof was on fire," said the homeowner.

The three people inside, including an elderly woman, were able to get out.

"I've never seen her move that fast," the homeowner said. "She got out really fast."

There were no injuries, but the house appeared to be ruined.
