The National Weather Service has a Severe Flood Warning in effect for Hardin and Jefferson counties in Texas, covering the Pine Island Bayou near Sour Lake and currently set to remain in force until 10:00 AM CDT on June 11, 2026. Minor flooding is occurring and forecast to continue in the warned area.
The alert matters because low-lying areas, roads, and locations near the bayou may see water overbank and rapid changes in depth. The warning signals that flooding is imminent or ongoingand that conditions can deteriorate quickly for motorists and residents in flood-prone zones.
Updated timing and river behavior at Pine Island Bayou
Officials indicated that minor flooding would persist along Pine Island Bayou near Sour Lake, with levels expected to fluctuate around flood stage. Earlier guidance placed the warning window through 1:00 AM CDT on June 10, with the river anticipated to crest near 25.3 feet tomorrow morning and then fall below flood stage early Tuesday afternoon. The advisory window has since been updated to extend through 10:00 AM CDT on June 11 to account for continued minor flooding and to keep protective measures in place while levels recede.
Impacts and safety guidance for residents
Minor flooding typically affects low-lying roads, access points, and areas adjacent to the channel, where water may cover surfaces and obscure hazards. Residents should avoid walking or driving through flooded areas, as water can be deeper and faster than it appears. If conditions worsen, move to higher ground and call 911 in emergencies. Officials urge the public to follow local instructions, monitor neighborhood impacts, and stay alert for any changes in the flood warning and river level updates.
Travel disruptions are possible where water crosses roadways near the bayou, and barricades or closures may be implemented to protect drivers. Those in frequently affected neighborhoods should secure belongings, check drainage, and prepare for short-notice adjustments. Continued monitoring of the Pine Island Bayou gauge and local announcements will determine when it is safe to return to normal routines. Last update: June 9, 2026.
