ADAIRSVILLE, Ga. — A massive storm system raked the Southeast on Wednesday, spawning tornadoes and dangerous winds that overturned cars on a major Georgia interstate and demolished homes and businesses. At least two people were killed.

In northwest Georgia, the storm system tossed vehicles on Interstate 75 onto their roofs. The highway was closed for a time, and another main thoroughfare remained closed until crews could safely remove downed trees and power lines from the road.
