UPDATE at 7:25 p.m.
A three-alarm fire broke out around 2 p.m. Thursday at a single family home at 2813 Lindberg Ave., across from .
Firefighters from neighboring departments helped Western Salisbury and Eastern Salisbury fire departments battle the blaze, which occurred shortly after an intense thunderstorm swept through the area.
There was some speculation the fire was caused by lightning. Neighbors said they saw a flash of light and heard a loud crack.
Western Salisbury Fire Chief Joshua Wells said the cause of the fire is still under investigation.
As the home filled with smoke, firefighters broke windows and climbed latters to get to the second floor. Firefighters stayed on the scene for several hours after the fire was extinguished.
The home is owned by Thomas and Laurel Brown, who have lived there five years. No one was home except a contractor who was inspecting his work in the basement, Thomas Brown said. The contractor smelled smoke and called the fire department.
"It was perfect timing," Brown said. "God was good. No one was hurt."
"We're very fortunate," Laurel Brown said. "We're very thankful it was our house and not our neighbors."
Brown said the house is unhabitable because it is filled with smoke.
Firefighters and emergency workers from South Whitehall, Cetronia Ambulance, Emmaus, Lower Macungie and Alburtis assisted.
