Tropical Storm Barry might be a fairly weak hurricane when it makes landfall in Louisiana late Friday or early Saturday — but people in its path are far more worried about flood risks from its heavy rains and storm surge than the damage its winds could cause.
“Barry is expected to produce total rain accumulations of 10 to 20 inches over southeast Louisiana and southwest Mississippi, with isolated maximum amounts of 25 inches,” the National Hurricane Center says. “These rains are expected to lead to dangerous, life-threatening flooding over portions of the central Gulf Coast into the Lower Mississippi Valley.”
As of 11 a.m. ET Friday, Barry’s maximum sustained winds had strengthened to nearly 65 mph, the hurricane center says, citing data from Hurricane Hunter aircraft. At the time, the storm was about 100 miles southwest of the mouth of the Mississippi River; forecasters say Barry could become a Category 1 hurricane before it makes landfall.
A hurricane warning — meaning hurricane conditions are expected — has been declared for the area from Grand Isle (some 50 miles south of New Orleans) westward to Intracoastal City, which sits along the Vermilion River.
Water levels were already rising along the coast Friday morning; the hurricane center says “peak inundation” won’t occur until Saturday. Images from Grand Isle showed Friday showed streets and yards covered with water near the coast — where most of the houses are perched on pilings.
For the past 24 hours, Barry has crept along at 5 mph, increasing concerns that it will slowly but steadily drench low-lying areas that have already been saturated with water in recent weeks.
Intense rainfall, like Barry is expected to bring, can trigger calamitous flooding. And with many areas along the lower Mississippi River already struggling to cope with huge amounts of rainwater from upriver, people in Louisiana and Mississippi are preparing for the worst.
Officials in New Orleans and nearby parishes have said their levees have room to accommodate 5-6 more feet of floodwaters. On Friday, many of the flood gates near the river were closed.
“Breezy with scattered showers here in New Orleans,” NPR’s Debbie Elliott reported Friday morning, as the city braced for the storm. Tulane and other schools had already planned to be closed Friday, along with government offices and youth programs.
To the west, the Terrebonne Parish Sheriff’s Office said that a flood gate at the small town of Cocodrie was closed Friday to help protect towns inland from Barry’s storm surge, NPR’s Rebecca Hersher says.
“Cocodrie is almost entirely empty this morning,” Hersher reports from Louisiana. She adds, “In Houma, southwest of New Orleans, a shelter opened this morning for people who are voluntarily evacuating from areas that aren’t protected by levees.”
In Terrebonne, neighboring Jefferson Parish, Baton Rouge and other parts of Louisiana, residents have been
Louisiana Gov. John Bel Edwards has declared a state of emergency for the entire state; on Thursday, he said he has also ordered 3,000 National Guard members to be deployed in case they’re needed in rescue and recovery operations.
In New Orleans, Mayor LaToya Cantrell says via Twitter, “High water vehicles and boats are pre-staged around the city should water rescues be necessary.”
