Atlanta flooding – After an hour of heavy rain backed up traffic along the Atlanta Connector and flooded roads across the metro, a driverless Waymo service suspended operations. Rain gauges also show parts of the northwest—especially Cumberland and Vinings—took the hardest hit o
Floodwater swallowed a self-driving car as drivers tried to get through rush hour on some of Atlanta’s busiest roads—part of a Memorial Day weekend that turned dangerous fast.
Intense rainfall over the past week has followed months of drought in Georgia. triggering power outages. ground stops and flash flooding in and around Atlanta. Last week. multiple inches of rain fell in the metro area within an hour. and the water backed up on major thoroughfares including the Atlanta Connector. where cars and their drivers became stranded.
The rain is not easing as the city heads deeper into May. The outlook for the rest of the week points to continuing instability, with more showers and thunderstorms forecast into early June.
Over the past 7 days, the hardest-hit spots in the Atlanta metro are clustered to the northwest. Vinings has logged 5.12 inches of rain over one week. while Cumberland—just northwest of the city—has recorded 6.98 and 7.35 inches in separate gauges. Further north in Sandy Springs, rain gauges recorded 6.79 inches over Sope Creek.
Just over 6 inches was recorded in Roswell. Multiple readings in northern Marietta and Woodstock also came in over 6 inches.
Elsewhere, the numbers show how uneven the storm’s footprint has been across the metro. Riverside received 4.16 inches of rainfall, and East Point recorded 2.21 inches. More than 3 inches fell across multiple parts of Panthersville and south Decatur.
On the east side of Atlanta, Brookhaven received around 3.5 inches over the week, while Chamblee recorded just below 2 inches.
Between North Druid Hills and Tucker, rainfall ranged from about 1.5 to 2 inches. Farther north into Norcross and Peachtree Corners, rain totals were closer to 3 inches.
Even with this burst of rain, Atlanta is still catching up from drought conditions. The city has received 11.82 inches of rain in 2026 through this point in the year. A year earlier, Atlanta had already recorded 15.31 inches by this time, and in 2024 the city stood at 24.03 inches.
Atlanta’s 30-year average for total rainfall by the end of May is 17.63 inches. That means the city would need nearly 6 more inches of rain over the next four days to get back in line with its typical pace.
The danger has not been limited to roads. The heavy rainfall has put Atlanta’s infrastructure under strain, flooding large sections of roadways and leaving drivers in need of rescue, while also putting driverless vehicles in the path of floodwater.
The car service suspended operations last week because of dangerous conditions, after water surrounded a Waymo vehicle.
The storms have also taken a toll on the natural world—especially in the Chattahoochee River. which runs through the northwestern corner of Atlanta and south of the city. Runoff from Atlanta and a sewer overflow have flooded the river with E. coli and other contaminants, leading to an “unprecedented” fish die-off for as many as 20 miles downstream.
Those impacts are happening on top of months of low river flow driven by drought. Officials and scientists warn that the combination could lead to catastrophic consequences for the Chattahoochee ecosystem.
The flooding comes as the National Weather Service annual data shows Georgia is still working to recover its lost rain, even as the forecast calls for more wet weather. Atlanta’s 10-day forecast includes:
Wednesday, 5/27 — High of 85, low of 68, scattered showers and thunderstorms. Thursday, 5/28 — High of 86, low of 70, partly cloudy. Friday, 5/29 — High of 79, low of 68, thunderstorms in P.M. Saturday, 5/30 — High of 80, low of 68, scattered thunderstorms. Sunday, 5/31 — High of 75, low of 64, scattered thunderstorms. Monday, 6/1 — High of 79, low of 64, A.M. showers. Tuesday, 6/2 — High of 79, low of 62, partly cloudy. Wednesday, 6/3 — High of 80, low of 61, mostly sunny. Thursday, 6/4 — High of 80, low of 63, mostly sunny. Friday, 6/5 — High of 81, low of 66, partly cloudy.
Taken together, the rainfall totals, the continuing forecast, and the river’s contamination all point to the same reality: this isn’t just a weekend storm. It’s a stress test for Atlanta—on roads, on power and on the water systems that keep both residents and ecosystems alive.
