ATLANTA – At least two people have died as thunderstorms rumbling across north Georgia spawned heavy downpours that flooded roads and homes and dumped as much as 20 inches of rain in the area over three days.

Emergency workers in Lawrenceville say they found a woman dead in her vehicle, which was submerged in water after having been swept from the road by flooding.

Dena Brummer of the Georgia Emergency Management Agency says that another person died in Douglas County after a vehicle was washed off the roadway.

The metro Atlanta area was under a flash-flood warning Monday and emergency workers in at least two counties rescued residents from high waters.

The rolling storms shut down school systems in Paulding County, Douglas County, Gwinnett County, Carroll County and Stephens County. It also flooded homes, washed out some roads and left standing water on some busy metro Atlanta highways.

Lisa Janak of the Georgia Emergency Management Agency says the rains caused a mudslide that blocked part of Stone Mountain Freeway. She says motorists should not drive through standing water and residents should stay home if they don’t have to drive.

Trisha Palmer of the National Weather Service says that as much as 20 inches of rain has fallen on the area since Friday as a series of strong storms rumbled through. She says parts of Douglas and Carroll counties have received more than a foot of rain in the last day alone.
