August 22 @ 7:30 p.m. – Phase 4 Mandatory Evacuation, Update 4

Tropical Storms Laura and Marco

Saturday, August 22, 2020
7:30 p.m.

Lafourche Parish officials have issued a mandatory evacuation for 12:00 noon tomorrow, Sunday, August 23, for the area below the lock in Golden Meadow. In anticipation of that evacuation order, GLPC is moving to GLPC Storm Phase 4: Mandatory Evacuation for Port Fourchon to give as much advance notice as possible to port tenants and users before the order goes into effect.

This means that all remaining personnel should evacuate the port in accordance with the Lafourche Parish President’s order.

Please secure hazards and clear non-essential equipment from facility grounds, prepare office areas to minimize water intrusion damage, secure buildings with storm shutters or plywood over windows and doors, secure fuel tanks and storage areas, shut off utilities (water, electricity, etc.) if possible, and remove all small craft that can be hauled or trailered from port facilities and waterways, well away from the effects of possible storm surge and high winds. Remember, all vessels remaining in port must be manned. No new mooring dolphin rentals will be accepted; any unleased dolphins will be considered first come, first served until the storm is over.

Tropical Storm Laura and Tropical Storm Marco are now both forecast to become hurricanes before they make landfall in coastal southeast Louisiana. Coastal flooding, heavy rain, and strong winds are all possible with these two systems. Marco is now expected to bring impacts to the area tomorrow; Laura’s impacts are expected during the Wednesday/Thursday time frame.

After the storms have 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.


  • RAINFALL: Potential for heavy rainfall, possibly beginning tomorrow evening and continuing all next week. Rainfall totals of 3-6 inches are forecast through Thursday, with locally higher amounts possible.
  • TIDES/STORM SURGE: Expected storm surge of 2-5 feet. Elevated tides and coastal flooding possible, with dangerous marine conditions expected through next week.
  • WINDS: Tropical storm force winds expected sometime between Sunday evening and Monday from TS Marco; TS Laura could bring strong, damaging winds Wednesday and Thursday. Short-lived and fast-moving tornadoes can occur in Marco’s outer bands as it moves ashore.
  • 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.

  • HURRICANE WATCH (for coastal areas of SE LA and MS) in effect.
