4:30 p.m.

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

Impacts are diminishing and road conditions on LA 1 between Leon Theriot Lock in Golden Meadow and Leeville are improving, but Port Fourchon remains under advisory due to coastal flooding concerns.

Roads are currently open to all vehicular traffic, but this could transition to road closure if tides rise and overtop the roadway on low-lying areas of LA 1 below the Golden Meadow Lock overnight.

Port Fourchon Harbor Police, Louisiana State Police, and Lafourche Parish Sheriff’s Office will be monitoring the condition of the roadway overnight, and the Port Commission will send out updates as they become available.


  • RAINFALL: Slight risk of excessive rainfall that could lead to flash flooding.
  • TIDES: Elevated tides are affecting low-lying portions of the area, with minor coastal flooding impacts likely near high tide.
  • ROADWAYS: Roads are currently open to vehicular traffic, but coastal flooding is a concern as always on LA 1 between the Leon Theriot Lock in Golden Meadow and the elevated LA 1 Expressway in Leeville.


WARNINGS, WATCHES, & ADVISORIES (Updated 9/22/2020 @ 4:00 PM):

  • Flash Flood Watch in effect for Lafourche Parish through Wednesday evening.
  • Coastal Flood Advisory in effect through 7:00 a.m. Thursday.
