The remnants of Isaac have left Louisiana behind, but parts of the state will be rebuilding for a while. The storm brought extensive flooding to communities that had been largely spared during earlier hurricanes. NPR's Joel Rose rode along as Louisiana's governor toured one such town on the north shore of Lake Pontchartrain outside New Orleans.
With Tropical Storm Isaac still over much of southeast Louisiana, Jefferson Parish Sheriff Newell Normand has ordered a dusk to dawn curfew for all Jefferson Parish residents. Authorities previously had not implemented a curfew because of the earlier forecasts for the storm.
Normand said Wednesday that deputies patrolling the streets over the past 24 hours have encountered curious pedestrians and motorists out joyriding through flooded roadways.
Residents of unincorporated Jefferson Parish, Kenner, Gretna, Westwego, Lafitte and Harahan are covered by the curfew.
Orleans and Jefferson Parishes are under a dusk-to-dawn curfew. St. Tammany Parish and East Baton Rouge are under curfew from 6 p.m. to 6 a.m.
About 800 homes have gotten significant damage in Plaquemines Parish, from flooding of four to nine feet over 18 miles. Officials say a levee was overtopped and breached.
Grand Isle is also reportedly still under two feet of water, and Crown Point, Barataria, and Lafitte are still battling storm surge. Surge is coming in at a fast pace, according to Jefferson Parish President John Young
Authorities in Plaquemines Parish, where storm surge from Hurricane Isaac caused extensive flooding overnight, have ordered a mandatory evacuation for a portion of the west bank of the Mississippi River.
The evacuation affects people living from Venice north to the Oakville floodgate on Louisiana Highway 23.
A shelter was to open at noon in Belle Chasse.
Officials said the evacuation was ordered out of concern that more storm surge from Isaac would be pushed into the area and levees might be overtopped.
Entergy says Hurricane Isaac has knocked out power to more than 450,000 residential and commercial in southeast Louisiana.
The company's website indicates that those included more than 150,000 in New Orleans, about 160,000 in Jefferson Parish, some 15,700 in St. Bernard, about 10,800 in Plaquemines, 27,300 in Lafourche, 16,000 in St. Charles, 16,700 in St. John the Baptist and 17,700 in Terrebonne Parish.
Officials say crews are not able to start repairs until winds drop below 30 or 35 mph, which is likely to be Thursday at the earliest.
