dpATLANTA – The remnants of Tropical Storm Arthur are moving into Georgia, setting the stage for a wet and potentially hazardous end to the workweek.
The FOX 5 Storm Team has declared Thursday a Storm Alert Day as tropical moisture spreads across metro Atlanta and North Georgia. While flooding remains the primary concern, forecasters are also increasingly concerned about isolated severe thunderstorms and brief tornadoes developing later in the day.
Rain was already moving through parts of metro Atlanta and North Georgia late Thursday morning, but meteorologists say the most significant impacts are expected this afternoon and evening.

Severe weather risk upgraded
The Storm Prediction Center upgraded much of metro Atlanta and areas along and south of the Interstate 85 corridor to a Level 2 of 5, or slight risk, for severe weather.
What they’re saying:
The risk area includes Atlanta, LaGrange, Newnan, Griffin, McDonough, Covington, Conyers, Lawrenceville, Athens, Commerce and numerous surrounding communities.
The greatest severe weather threat will be from brief spin-up tornadoes that can develop quickly within tropical rain bands. The window for those storms is expected to be between 3 p.m. and midnight.
“The threats will exist,” FOX 5 Storm Team meteorologist Alex Forbes said. While the tornado threat remains relatively low, he noted that a handful of tropical tornadoes cannot be ruled out.
In addition to tornadoes, isolated damaging wind gusts and scattered power outages are possible.
Rising flood dangers
What we know:
Heavy rainfall continues to be the primary threat across much of Georgia.
A Flood Watch remains in effect for dozens of counties across north, central and west-central Georgia, including much of metro Atlanta.
Forecasters expect widespread rainfall totals of 2 to 4 inches, with some communities potentially receiving more than 5 inches before the system moves out.
The Weather Prediction Center has also placed parts of metro Atlanta and North Georgia under a Level 3 of 4 risk for excessive rainfall, signaling an elevated threat for flash flooding.
Because the ground is already saturated from recent rain, creeks, streams and low-lying roads could flood quickly.
A Flood Watch is in effect from Thursday morning through late Friday morning for Baldwin, Bibb, Bleckley, Butts, Crawford, Crisp, Dooly, Houston, Jasper, Jones, Monroe, Peach, Pulaski, Putnam, Twiggs, Wilkinson, Greene, Hancock, Washington, Barrow, Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Forsyth, Gwinnett, Henry, Morgan, Newton, Rockdale, Fulton, Walton, Oconee, Bartow, Carroll, Haralson, Paulding, Polk, Chattahoochee, Coweta, Harris, Heard, Lamar, Macon, Marion, Meriwether, Muscogee, Pike, Schley, Spalding, Stewart, Sumter, Talbot, Taylor, Troup, Upson and Webster.
Evening commute could be messy
The heaviest rain is expected to arrive during the afternoon and evening hours, creating the potential for dangerous travel conditions.
FOX 5 Atlanta Meteorologist Greg Majesky said rain and storms will increase throughout the afternoon before peaking during the evening commute and continuing into the overnight hours.
“This is just the warm-up act,” Majesky said while tracking developing rain bands Thursday morning. He warned that the combination of heavy rain and isolated severe storms could create a “problematic rush hour.”
Drivers are encouraged to avoid flooded roadways and allow extra travel time Thursday afternoon and evening.
Atmospheric vacuum effect
Big picture view:
A tropical disturbance moving inland from the Gulf Coast is interacting with a cold front pushing down from Canada. This setup forms a atmospheric conveyor belt that streams highly unstable, moisture-packed air directly into Georgia. The system will slowly push east, but the tropical ingredients will linger long enough to keep weather conditions active through the end of the week.
Heavy local downpours
Local perspective:
This incoming tropical wave brings a high potential for torrential downpours rather than scattered summer showers. Localized downpours will dump heavy amounts of rain over short periods, which will quickly fill up creeks and low-lying roads. The highest rain totals are expected to target the southern suburbs of metro Atlanta and central Georgia.
Georgia Power says it’s ready
What they’re saying:
Georgia Power said crews are prepared to respond to storm-related outages as conditions safely allow. The utility warned that saturated ground, heavy rain and gusty winds could bring down trees and damage power lines, leading to scattered outages. Customers are encouraged to charge devices, monitor weather updates and avoid downed power lines, which should always be treated as energized and dangerous. Click here for safety tips.
Looking ahead
What we know:
Conditions should gradually improve after midnight as the heaviest rain shifts east.
Showers and storms will remain possible Friday, but forecasters expect the flood threat to diminish heading into the weekend.
Historic June chill

Father’s Day sunshine
What’s next:
The bulk of the tropical energy will push east of Georgia by early Saturday morning, allowing the flash flood threat to expire. A weak cold front moving in from the north will shunt the deep moisture further south into central and southern Georgia. This brings a brief return to drier weather for most of north Georgia this weekend before typical summer humidity returns next week.
