Overview
- A line of intense thunderstorms on Saturday dumped several inches of rain in short bursts and prompted National Weather Service flash‑flood warnings across the New Orleans metro.
- The Sewerage & Water Board reported multiple pump problems during the storm and said an employee error prevented all three pumps at the Canal Boulevard (DPS 7) station from coming online for about 45 minutes.
- S&WB says the immediate pump outages have been fixed, the agency will add staff at the DPS 7 site and it has opened an internal investigation into the operational mistake.
- The storms overwhelmed drainage capacity—S&WB designs pumps to handle about 1 inch of rain the first hour and 0.5 inches each additional hour—producing localized totals up to roughly 3–3.5 inches and rapid rises such as 6 feet of water at Canal Boulevard in 20 minutes.
- Neighborhoods including Mid‑City, Lakeview, City Park, Hollygrove and Uptown saw flooded streets, stranded cars and closed underpasses and residents say persistent catch‑basin and deeper drainage limits mean short storms can still cause major street flooding.
