Update, 2:35 p.m.

A mandatory evacuation has been issued for portions of Plaquemines Parish ahead of Hurricane Nate. 

The order is in effect as of 3 p.m. for the entire eastbank and areas outside the levee protection system. Residents on the westbank from Oakville Floodgate to Venice are also called to evacuate. 

Update 1:30 p.m.

The Gretna City Council has authorized a curfew in advance of Hurricane Nate's expected arrival this weekend, though the times have not been set and Mayor Belinda Constant said tonight's "Back to the River" concert will go on as planned.

Constant said that if a curfew is instituted it would likely be for Saturday and that the planned screening of a movie on the riverfront scheduled that night has been canceled.

She said any curfew would be declared by the Gretna Police Department at some point before then.

At an emergency council meeting called for 1 p.m. Friday, the council passed an ordinance stating a "mandatory curfew is hereby authorized as directed by the Gretna Police Department and when declared by the Gretna Police Department shall remain in effect during the times established by the department until further notice."

The ordinance does state the penalty for violating the curfew is a $500 fine and 60 days in jail.

Nate is expected to arrive in the Gulf Coast overnight Saturday.

Update 11:10 a.m.

Grand Isle Mayor David Camardelle has called for a mandatory evacuation of the island, he said.

The threat of high tides and storm surge from Hurricane Nate is what prompted the call, he said.

Update 10:50 a.m.

Jefferson Parish President Mike Yenni is also encouraging residents in Lower Barataria, Crown Point and any other low lying areas outside the levee protection system.

The Town of Grand Isle issued a volunteer evacuation Thursday.

Original Story:

Mayor Timothy Kerner and the town council have ordered a mandatory evacuation of the Town of Jean Lafitte effective 10 a.m. Friday, according to a news release.

Tides driven by Hurricane Nate may reach as high as eight feet, which could swamp areas of the low-lying town, Kerner said.

"If anyone has vehicles, boats or campers in low areas they should bring them to higher areas until this storm has passed," Kerner said. Town and parish officials are working to make sure the elderly have transportation out of town and that backup generators are available where needed.

The evacuation will be strictly enforced on Saturday evening as Nate approaches, Kerner said.

Hurricane Nate is expected to make landfall along the gulf coast late Saturday or early Sunday, according to the National Weather Service.
