National Weather Service issued a Severe Coastal Flood Warning for West Cameron and Lower Jefferson Texas, beginning at 10:16 AM CDT on 31 August 2026 and running until 7:00 PM CDT on 1 September 2026.
Officials highlighted that the overlapping advisories, including an extended Severe Flood Watch amplified the risk of life-threatening inundation along the coast and inland. Ultimo aggiornamento: 1 September 2026.
Why the warnings matter for coastal and inland areas
The consolidated alerts cover coastline locations such as NederlandPort ArthurSabine Pass and Sea Rim State Park where an Extreme Storm Surge Warning was active into 1 September 2026. Forecasts indicated a potential for 3-5 feet of storm surge inundation above ground in surge-prone areas, creating a significant threat to low-lying homes, businesses and transportation corridors.
Wind and rainfall components were included in the update: winds of 25-35 mph with gusts up to 45 mph and additional rainfall of 2-4 inches, with locally higher amounts, raised concerns about drainage capacity and urban flooding in areas named in the watch such as Tyler Southern Jasper, Southern Newton, Upper Jefferson and Northern Orange.
Timing, overlapping watches and operational impact
The Severe Coastal Flood Warning explicitly named West Cameron and Lower Jefferson with the active window starting at 10:16 AM CDT on 31 August 2026 and ending at 7:00 PM CDT on 1 September 2026. An overlapping Severe Flood Watch ran from 10:07 AM on 31 August 2026 until 7:00 AM on 2 September 2026, extending the period of concern into early September 2026.
An Extreme Storm Surge Warning was issued at 3:57 AM CDT on September 1, 2026 and was in effect for portions of the same coastline for the day, with a specified expected end time of 14:00 on September 1, 2026 in some notices and an earlier local expectation through 06:15 on 1 September 2026 in others, creating an extended and partly overlapping threat window.
Local guidance and expected effects
Emergency officials urged residents in affected zones to prepare for possible evacuations, move to higher ground if necessary and avoid flooded roads. They reiterated: “If travel is required, do not drive around barricades or through water of unknown depth.”
Authorities warned of shoreline erosion, road closures and inundation of low-lying properties as likely outcomes. Municipal and emergency services in Jefferson and adjacent counties positioned resources to respond to reported inundation, poor drainage and urban flooding while tracking tide, surge and rainfall trends into 2 September 2026.
