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.
The Louisiana Department of Transportation and Development (DOTD) announced that it is in the process of restaging its busing assets to locations outside of the potential path of the storm and away from flood zones to ensure they are accessible for citizens' future use.
DOTD will maintain 10 coaches, one van and one pet carrier at Zephyr field if an immediate need arises.
Two shelters have opened in St. Tammany Parish as Hurricane Isaac approaches.
Officials of the St. Tammany Parish School Board and the Red Cross said the shelters are at William Pitcher Junior High School, 415 S. Jefferson Ave. in Covington and at Creekside Junior High School, 65434 Louisiana Highway 41, Pearl River.
People going to the shelters are asked to bring food, medicine, bedding and activities for children.
Assumption Parish officials have announced a mandatory evacuation of the parish in advance of Hurricane Isaac's landfall.
The parish has reportedly banned the sale of alcohol, and has announced a curfew.
Assumption has also opened a shelter of last resort, at Belle Rose Middle School (7177 Highway 1). Officials say the school will be running off of generator power; however, all evacuees are required to bring all necessary items with them, including food, water, toiletries, bedding and medicines. No cots will be provided.
The St. Charles Parish President has called for a mandatory evacuation effective at 6 p.m. Sunday for all residents in St. Charles Parish due to Tropical Storm Isaac.
What does this mean? It means that conditions from Hurricane Isaac will be such that widespread damage and flooding are possible. It also means that vital services such as food stores, fuel and medical services may be unavailable for an indefinite period. Accordingly, residents are strongly advised to seek shelter outside of St. Charles Parish.
