Like New Orleans, Jefferson Parish leaders are asking residents to stay inside unless absolutely necessary, and stick to that for a little while even after the storm passes.
"Traffic is actually very light," said Sheriff Joe Lopinto. "Most people are off the roadways. We want to keep it that way."
Lopinto said even after the bad weather moves on, they want people to sit tight for a little while.
"When pumping capacity at our pumps can pump enough water, we can fill the Smoothie King center in six minutes and the Superdome in 46 minutes," said Yenni. "This parish has put three new pumping stations online this past year."
Low-lying areas of Jefferson were told to evacuate Friday. For anyone who remained on Grand Isle. a curfew begins at 10:00 p.m. LA 1 is closed between Grand Isle and Port Fourchon, and the island is already experiencing tropical storm-force wind gusts.
