Workers were evacuated from offshore rigs as officials continued to monitor a cluster of thunderstorms in the Gulf of Mexico that could develop into Tropical Storm Debby.
The system, which was off the Yucatan Peninsula Friday night, has an 80 percent chance of developing over the weekend, according to the National Hurricane Center.
Computer forecasts vary on which way the system will go. Some models have it heading into Texas; others predict it will go north for awhile, before going toward Texas.
If it goes east, WWL-TV meteorologist Jonathan Myers said locals can expect a 30 percent chance of rain, highs in the 90s and higher than average tides.
If it goes toward Texas, the 'weekend would be wetter, windier and somewhat cooler,' Meyers says in a news release.
Forecasters say they should have a better idea of the storm's potential by this afternoon.
Local officials said the southern reaches of Terrebonne and Lafourche should prepare for possible flooding.
Floodgates in Larose and Golden Meadow were closed Friday morning. The flood risk in Lafourche depends on the storm's track, said Windell Curole, head of the South Lafourche Levee District.
A path that takes it west of Lafourche could result in flooding that would submerge parts of La. 1, he said.
In Terrebonne, the Humble Canal floodgates closed Friday and will stay closed through the weekend, officials say. 'The gate takes so long to open and close so it will be easier for us to keep them closed all weekend,' said Angela Rains, Terrebonne Levee District manager.
The Bayou Terrebonne and Little Caillou floodgates remained open Friday evening because they closed as the tides change, Rains said.
'We have employees out monitoring the gates and when conditions are favorable they will be opened,' Rains said.
