A tree came crashing down near the intersection of Bolton Rd and Moores Mill Rd NW late Wednesday morning.
The tree struck two vehicles and knocked down power lines.
Atlanta Police said the occupants of the vehicles were not injured and no one was trapped.
A worker in a nearby air conditioning truck told 11Alive News that he helped the driver of one of the cars, a Mercedes, to escape once the tree landed on it.
