Thunderstorms rolled through North Texas in the early hours Today, April 26, prompting the National Weather Service office in Fort Worth to issue a flash flood warning for Dallas County. The agency confirmed the warning at 1:34 a.m. and kept it in effect until 4:45 a.m., as Doppler radar tracked heavy rainfall building across the region.
Between 1 and 2 inches of rain had already accumulated by the time the warning went out, with forecasters projecting an additional 1 to 2 inches before conditions improved. That combined total was more than enough to overwhelm drainage systems across the county, particularly in urban corridors and low-lying neighborhoods that flood quickly even during moderate rainfall events.
Dozens of communities affected across the region
The warning extended well beyond the Dallas city limits. Communities including Arlington, Grand Prairie, Mesquite, Desoto, Cedar Hill, Duncanville, Lancaster, Balch Springs, Seagoville, Glenn Heights, Hutchins, Cockrell Hill, Wilmer, Ferris, Combine, Sand Branch, and Cockrell Hill all fell within the alert zone. Recreational areas were not spared either, with Cedar Hill State Park, Mountain Creek Lake, and Joe Pool Lake among the impacted locations.
The NWS cautioned that flooding was already underway or expected imminently in small creeks and streams, on highways and surface streets, and in underpasses throughout the warned area.
Flood safety guidance issued alongside the warning
Weather officials repeated their well-worn but critical message to drivers: turn around, do not attempt to cross flooded roads. The agency noted that the majority of flood-related deaths happen inside vehicles, and that nighttime conditions make the danger significantly harder to gauge. Floodwater depth is notoriously difficult to judge in the dark, and even roads that appear passable can conceal fast-moving currents capable of sweeping a vehicle off course…
