Storm‑Wet Southeast Faces New Flood Risk
Southeast United States, Birmingham, Atlanta, Myrtle Beach, Greensboro, Winston-Salem, Knoxville, Durham, USASaturday, July 25, 2026
The tropical storm that once called itself Bertha has faded, but the wet air it left behind remains a danger.
Texas: A Quiet End
- In Texas, the storm concluded with only a few heavy showers, primarily near Houston.
Southeast: Stalled Moisture
- A patch of that moisture has adhered to a slow front moving across the Southeast.
- The front is now stalled, causing rain to linger over the same spot longer.
Friday’s Thunderstorms
- Afternoon thunderstorms swept through northern Alabama and Georgia, dropping 1–2 inches of rain in a short period.
- This triggered flash‑flood warnings in Birmingham and Atlanta.
- While rain is needed to break a long drought, excess rainfall can cause floods.
- If the ground cannot absorb 2 inches per hour, water will accumulate.
- Some areas could see over 4 inches of rain in a day—roughly the amount most cities receive in an entire month.
- Myrtle Beach averages 5.4 inches of rain in July alone.
Widespread Risk
- The risk extends from the coastal Carolinas to inland towns like Sumter, South Carolina and Fayetteville, North Carolina.
- Other parts of the Southeast may also experience heavy rain that could flood on Saturday.
Timeline of Events

Bertha’s Path
- First touched land in southeast Louisiana on Wednesday.
- Wind gusts over 40 mph at New Orleans Lakefront Airport.
- Moved west along the Louisiana coast before making its final landfall near the Texas‑Louisiana border on Thursday.
- Only the second named storm of the Atlantic hurricane season, which has been slower than recent years due to El Niño’s influence on the basin.
