The National Weather Service kept a Severe Flood Warning in effect through 4:00 PM CDT on June 25, 2026, for the Navasota River near Normangee, covering Brazos, Grimes and Madison counties in Texas. Moderate flooding is forecast, with the river expected to crest near 18.1 feet late this evening, while flood stage is 15.0 feet and bankfull is 12.0 feet. Last update: June 23, 2026.
The alert matters because low-lying areas and at least one local roadway are expected to be inundated as the river exceeds flood stage. Hydrologic guidance now points to a lower peak than earlier projections, but water levels remain in the moderate flood range and could affect travel and property along vulnerable bottomlands. Officials advised that most flood fatalities occur in vehicles and that conditions can change quickly as upstream runoff works through the channel.
Warning timing and latest crest guidance
The warning remains active until the stated expiration and covers communities along the Navasota from Brazos into Grimes and Madison counties. Forecast guidance has been revised downward in successive updates, from an earlier 19.4 feet projection to 18.5 feet, and now to about 18.1 feet late this evening, reflecting updated river response to upstream runoff and new stage observations. If no additional rainfall alters the recession, officials indicated the river should fall back below flood stage early Thursday morning, ending the immediate threat.
As of the latest report, the observed stage near Normangee was about 17.0 feet, already above the 15.0-foot flood stage and climbing toward moderate flood. At 18.0 feet, moderate lowland flooding begins, with widespread inundation across the floodplain. The crest timing near late evening keeps the period of greatest impact concentrated overnight, when visibility is reduced and risks to motorists increase.
Local impacts near Normangee
Flood impacts include water over Long Trussel Road in northeast Brazos County when levels reach around 18.0 feet, with additional low-lying roads and pastures near the channel also affected. Communities situated along bends and cutoffs should anticipate rapid water spread across adjacent bottomlands as the river briefly peaks. While the projected peak has eased compared with earlier outlooks, sustained flows near the crest can prolong inundation on adjacent lands before recession begins.
Residents in flood-prone zones should monitor official updates and be prepared for short-notice changes as forecast guidance is refined with new data. Emergency officials urged drivers to avoid flooded roads and not to bypass barricades, stating, “Turn around, don’t drown.” In an emergency, people should call 911 and follow directions from local authorities while staying clear of fast-moving water.
