Sept. 15 @ 7:45 a.m. – Sally Phase 5 Storm in Port, Update 11

Hurricane Sally

Tuesday, September 15, 2020
7:45 a.m.

Port Fourchon currently remains in Storm Phase 5, which is Storm in Port, as Hurricane Sally has slowed significantly but not yet made landfall. Sally, now a slightly weaker Category 1 hurricane, is expected to make landfall near the Mississippi/Alabama border early Wednesday. Impacts now are focused across coastal Mississippi, but Port Fourchon remains under advisory due to coastal flooding concerns as we approach high tide.

Lafourche Parish has issued a mandatory evacuation for all residents and businesses south of the Leon Theriot Lock in Golden Meadow as of 12:00 p.m. on Sunday, September 13, 2020.

Rising water levels have caused some water encroaching on roadways below the Golden Meadow Lock.

Roads are currently open to vehicular traffic, but this will transition to road closure if tides rise and overtop the roadway on low-lying areas of LA 1 below the Golden Meadow Lock. LA DOTD has suspended tolls on the elevated LA 1 Expressway in Leeville.

Port Fourchon Harbor Police will be monitoring the condition of the roadway, and the Port Commission will send out updates as they become available.

A checkpoint manned by Port Fourchon Harbor Police has been put in place at GLPC’s Fourchon Operations Center on LA 3090 to monitor traffic in and out of the port and maintain safety during mandatory evacuation.

After the storm has passed and roadways are cleared for passage, the Port Commission will notify port businesses when limited or full access is given to tenants to return and assess any damage to facilities.

All GLPC offices are on office closure until 6:00 a.m. on Wednesday, September 16, 2020, but GLPC Harbor Police and essential personnel will remain on duty during the storm to monitor conditions and take action as needed. NOTE: Emergency services may not be readily available in areas under mandatory evacuation during extreme weather events. As during any emergency, dial 911.


  • RAINFALL: Potential for heavy rainfall and squalls associated with outer rain bands.
  • TIDES/STORM SURGE: Storm surge of 1-3 feet expected. Tides are elevated below the floodgates.
  • WINDS: Strong, gusty winds possible.
  • ROADWAYS: Roads are currently open to vehicular traffic, but coastal flooding is a concern as always on Hwy 1 between Leon Theriot Flood Gates in Golden Meadow and Elevated Hwy 1 in Leeville. 


WARNINGS, WATCHES, & ADVISORIES (Updated 9/15/2020 @ 5:00 AM):

  • Coastal Flood Advisory in effect for Port Fourchon.
