Overview
- A line of intense thunderstorms on July 11 produced rapid urban flash flooding and prompted a National Weather Service flash‑flood warning for parts of the New Orleans metro.
- The Sewerage & Water Board confirmed multiple pump problems, including DPS 7 and reduced capacity at Pritchard, and said the Canal Boulevard station’s pumps were offline for about 45 minutes because of a human error.
- Flooding stranded vehicles and closed roadways across several neighborhoods, forcing closure of the Canal, Carrollton and Broad underpasses and both directions of Carrollton Avenue at I‑10.
- SWBNO says the pump problems were fixed and water has receded in many spots, and the agency announced steps to add staff at affected stations and open an internal investigation into the outage.
- Forecasts call for continued tropical moisture with 1–3 inches common and localized higher totals through Monday and Tuesday, keeping street flooding risk elevated and underscoring warnings to avoid driving through flooded roadways.
