GLPC is in Storm Watch phase and monitoring the development of Tropical Storm Sally. Businesses and coastal residents should be alert for new updates and warnings and need to be prepared to take quick action if necessary.

Tropical Storm Sally is forecast to become a hurricane in the Gulf of Mexico and make landfall somewhere between Grand Isle, LA, and the Alabama/Florida line on Tuesday. Although Sally is not currently forecast to impact Port Fourchon directly, the storm track remains somewhat uncertain. Coastal flooding, heavy rain, and strong/damaging winds will all be possible.

Please review your facility’s hurricane plan, be thoughtful of stockpiling any loose material or excess items that could fly away or be damaged if Port Fourchon is affected by a storm, and make sure the Port Commission has your facility’s updated contact information so that you can receive timely storm-related information.


  • RAINFALL: Rainfall totals of 5 to 10 inches are forecast through Tuesday, with locally higher amounts possible. Slow movement of this system could create significant rainfall and associated flooding threats.
  • TIDES: Elevated tides could affect portions of the area. Storm surge could begin as early as Monday morning.
  • WINDS: Increased probability of sustained tropical force winds. Strong winds possible late Sunday into Monday.
  • ROADWAYS: No closures at this time.


WARNINGS, WATCHES, & ADVISORIES (Updated 9/12/2020 @ 4:00 PM):

  • Flash Flood Watch in effect for Lafourche Parish from Sunday evening through late Wednesday night.
