The National Weather Service extended the Severe Flood Warning for Hardin and Jefferson counties in Texas, keeping it in effect until 10:00 AM CDT on June 11, 2026, for areas along Pine Island Bayou near Sour Lake. Minor flooding is occurring and remains forecast in low-lying locations and along roads near the bayou. Last update: June 9, 2026.
The extension matters for residents and commuters because water may continue to inundate low-lying areas and impede travel on flood-prone routes. An active Flood Warning means flooding is imminent or ongoing, requiring continued readiness and adherence to official guidance.
Extended alert window and affected area
Officials now indicate the warning will remain active until the morning of June 11, superseding earlier guidance that cited an expiration at 1:00 AM CDT on June 10. The focus remains the Pine Island Bayou near Sour Lake, where minor flooding has been observed and is expected to persist. Communities in Hardin and Jefferson counties adjacent to the bayou and its tributaries should anticipate periodic water rises where banks are exceeded and drainage is slow.
Residents were previously advised that the river would crest at 25.3 feet “tomorrow morning” before falling below flood stage by early Tuesday afternoon. With the extended warning period now in place, authorities continue to monitor levels and timing closely and may update forecasts as conditions evolve.
River levels and safety guidance
Minor flooding implies water overtopping banks into adjacent low ground, with possible impacts to secondary roads, pastures, and access points. Drivers should avoid flooded roadways, as water depth and current can be deceptive. Those in flood-prone zones should move to higher ground if necessary and keep essential items ready in case access routes become compromised.
Emergency services remain available via 911 for immediate assistance. Residents are urged to follow instructions from local authorities and the National Weather Service, and to monitor trusted local updates for any changes to timing, crest forecasts, or road conditions. As water levels fluctuate along Pine Island Bayoucontinued vigilance is advised until gauges confirm a sustained drop below flood stage and the warning is lifted.
