As the National Hurricane Center currently has placed landfall for Isaac at Gulfport on Wednesday at 7 a.m. as a Category 2 hurricane, a hurricane watch continues to be posted that includes lower Plaquemines and St. Bernard parishes. Plaquemines Parish President Billy Nungesser this morning declared a state of emergency and St. Bernard Parish President David Peralta is holding off until he has afternoon phones conferences with the Governor's Office of Homeland Security and Emergency Preparedness and the National Weather Service.
Forecasters have warned that confidence in the storm's long-range track forecast "is quite low, and it is too early to determine exactly where and when Isaac will make landfall along the Gulf Coast." More tracking adjustments might be necessary later today.
This morning, Peralta and Bob Turner, regional director of the Southeast Louisiana Flood Protection Authority - East, have been arguing about when to close the flood control structure at Bayou Bienvenue. The Bayou Durpre flood control structure already is closed due to ongoing construction.
The Bayou Bienvenue lock was scheduled to begin closing at about noon. Turner initially wanted to close the structure at 11 a.m., citing already rising water.
Peralta said he wants to push the closure until 3 p.m. so that fishermen still out in the area waters could have more time to return and has been working with Governor's Office. The fishermen could still get back home but it would take them much longer as they'd have to take alternative routes.
"Oyster luggers don't go that fast," Peralta said about the boats still out there. "They are not like a speed boat, a bass boat. It takes them 6 hours from Oakdale to the Bayou Bienvenue lock."
"The water (Bob Turner) is worried about, isn't in the streets yet," Peralta continued. "I need to get my boats in."
Peralta hopes that if the water recedes a bit this evening that the control structure could be temporarily reopened to allow some fishermen to return.
On the east bank of Plaquemines Parish, parish officials are lining newly raised levees with Visqueen, a plastic sheeting material, to protect areas with exposed dirt, according to a recent parish announcement. On the west bank of Plaquemines, additional Hesco baskets, similar to wire trash cans lined with fabric, are being added to close gaps in low lying area of Louisiana 23.
Sandbags are being added to levees that are part of the hurricane protection system in Pointe-a-la-Hache.
Plaquemines Parish officials plan to meet with Army Corps of Engineers officials later today to discuss plans for the barges currently pumping water into intakes in Port Sulphur and Pointe-a-la-Hache to prevent saltwater intrusion into the parish's drinking water supply.
