Flash flood warnings issued across Texoma as heavy rain floods roads in Oklahoma, Texas

The National Weather Service issued and extended flash flood warnings across the Texoma region on Tuesday, June 23, 2026, after heavy rain pushed water onto roads in southern Oklahoma and parts of northeast Texas. Forecasters reported flooding that was already underway or expected to develop, and the warnings reached communities on both sides of the state line. The alerts came from three of the weather service's forecast offices.

In Oklahoma, the weather service's Norman office issued a flash flood warning after radar picked up thunderstorms producing heavy rain. The office said flash flooding was occurring or imminent and warned that streets, highways, underpasses and other low-lying ground were the most likely places to flood.

South of the state line, the agency's Shreveport office extended a flash flood warning covering parts of northeast Texas. Radar there showed two to six inches of rain had fallen, and forecasters reported flooding was underway. Extending the warning kept it in effect across those areas as the flooding continued.

The flooding threat was not limited to one area. Warning text from the weather service's Tulsa office listed heavy-rain flash flood warnings across multiple Oklahoma counties, a sign the storm system covered a wide stretch of the region rather than a single town or county.

The warnings also spanned more than a single day. The Tulsa text was dated Monday, June 22, while the Norman and Shreveport warnings went out Tuesday, June 23, a sequence consistent with heavy rain crossing the region over consecutive days.

The Shreveport office's local storm reports documented recent flooding on the ground. That log, the running record of observations that trained spotters and emergency responders send in during active weather, noted water standing over roadways and a dispatch that sent first responders to a vehicle rescue. The weather service gathers such field reports as events unfold, separate from the formal storm data it reviews and finalizes afterward.

The warnings released this week are the live products forecasters put out as storms move through, and they remain part of the public record. The national archive that later confirms severe weather, NOAA's Storm Events Database, currently runs only from January 1950 through February 2026. Because that catalog does not yet extend into the summer of 2026, it holds no final entries for the flooding that hit the region this week. Until federal staff review and add those events, the warnings from the Norman, Shreveport and Tulsa offices remain the official account of the storms.
