Fire crews say the entire one-story building was fully engulfed in flames when they arrived, and the front of the building was charred. Fire officials say it apparently got so hot inside that the roof started sagging because of the weakening metal.
The smoke and fire expanded for quite some time before crews could knock out the flames.
"The good news is no one is hurt and the fire did not spread beyond this building, even though the buildings right in front of it facing Harrisburg is only two feet apart," said Chief Terry Stone with the Houston Fire Department.
While it's too early to say exactly what started this massive fire, Chief Stone says the intense lightning is likely a factor. Arson investigators are still looking into it.
