Sept. 21 @ 10:30 a.m. – TS Beta Phase 1 Storm Watch, Update 5

Tropical Storm Beta

10:30 a.m.

GLPC remains in Storm Watch phase, monitoring the weather associated with Tropical Storm Beta.

Roadway conditions on LA 1 between Leon Theriot Lock in Golden Meadow and Leeville have not been deemed safe for passage by Louisiana State Police as coastal flooding continues in low-lying areas.

Assuming water levels recede enough to allow travel on LA 1 from Golden Meadow sometime midday today near low tide, there is a potential window to allow a onetime limited convoy to and from Port Fourchon for dock facility personnel only to get people and/or supplies in or out of port. Port Fourchon Harbor Police will be monitoring traffic at a checkpoint to ensure that access is limited to port facility personnel only.

Port tenants and dock facility personnel, please be prepared for a short window of time to get in and out, be alert for updates regarding water levels and impending road closures, and prepare any ingoing personnel for several days’ stay in Fourchon. This flooding is expected to stretch over the next few days as we continue to get hit with tropical winds, rain, and storm surge, and we anticipate the road being closed below the floodgates for the next few days.

GLPC is in communications with Louisiana State Police, the Lafourche Parish Sheriff’s Office, and Lafourche Parish President Archie Chaisson III to ensure that LA 1 south of the Leon Theriot Lock in Golden Meadow will reopen when passage is safe and roadways are clear.

GLPC Harbor Police, Lafourche Parish Sheriff’s Office and Louisiana State Police are on scene and will continue to monitor water levels and roadway conditions and will send out updates as they become available.


  • RAINFALL: Potential for prolonged rainfall of 3-5 inches through Wednesday, with locally higher amounts possible. Slow movement of this system could create significant rainfall and associated flooding threats.
  • TIDES: Elevated tides are affecting low-lying portions of the area.
  • WINDS: Strong winds possible.
  • ROADWAYS: Roads are currently closed to vehicular traffic below the Leon Theriot Lock in Golden Meadow.
