NORTH GEORGIA — A Flood Watch is active through late tonight across north Georgia as another round of very heavy downpours is expected to develop later Monday, May 25, 2026, on top of already saturated ground that has absorbed over 4 inches of rainfall across much of the north metro area in the last 72 hours. Parts of Cobb and Cherokee counties received that much rain in a single storm Sunday evening alone, triggering flash flooding, and the threat for street and small stream flooding continues through tonight as additional heavy rain arrives.
Over 4 Inches in 72 Hours Already Recorded Across North Metro Atlanta Corridor
The 72-hour rainfall total maps show widespread red and yellow signatures blanketing north Georgia, with the heaviest concentrations centered across the north Atlanta metro including Cobb, Cherokee, Woodstock, Acworth, Marietta, Roswell, and Sandy Springs. Some of the most intense totals on the zoomed-in rainfall map show deep red cores across the Woodstock, Acworth, and Roswell corridor indicating the highest accumulations from the multi-day event.
Parts of Cobb and Cherokee counties recorded over 4 inches in a single storm during Sunday evening, a staggering amount that immediately overwhelmed drainage systems and triggered flash flooding across streets and small streams. The ground across the entire north metro zone is now fully saturated with virtually no capacity remaining to absorb any additional rainfall.
