The levee system played an important role during Isaac's visit to New Orleans - learn more about the project that restored the system after Katrina and also get real-time updates of the operations in progress to respond to Hurricane Isaac:
Update: August 30th
Tropical Storm Isaac continued to batter the Louisiana / Mississippi region today as it moved so slowly. It has finally become a Tropical Depression and picked up some speed, up to 12 MPH.
Isaac is still impacting cruise schedules with Carnival Elation being the latest victim. It was originally scheduled to sail out of New Orleans on a 4-day itinerary August 30th. That was changed to a 3-day from Mobile, Alabama on August 31st. Even that is at risk because both ports remain closed. Carnival Cruise Line is monitoring the situation and advising passengers via text and posts on their website. We have the link for updates below.
Cruise Impact
Cruise lines continue to monitor the progress of Isaac which is expected to become a hurricane this weekend. Several cruise itineraries have been impacted as well as ports have announced closures.
We will attempt to keep this site updated as additional changes are made to cruise ship itineraries. For the absolute latest published information see the cruise line links directly.
All changes are being made with the interest in safety of the ships, crew, and passengers. Please be certain that you cruise specialist, cruise line, and airlines have your contact information. Monitor the internet and other news media for updates.

Tropical Storm Isaac made landfall along the southern coast of Haiti early
Saturday morning, and has begun to move away from Haiti and towards southeastern
Cuba, with its circulation relatively intact.
Isaac is expected to make
landfall in southeastern Cuba this afternoon, then skirt the northeastern coast
of Cuba through the overnight hours tonight.
Once off the northern coast of Cuba, Isaac is expected to strengthen into
a hurricane over the warmer waters of the Florida Straits and cross the Florida
Keys sometime Sunday night or early Monday morning, then head into the very warm
waters of the eastern Gulf of Mexico.

Hurricane warnings have been issued for portions of the northern Gulf Coast as
Tropical Storm Isaac continues its west-northwestward march into the Gulf of
Mexico.
Isaac will continue to affect southern Florida with heavy rain, gusty
winds and a tornado threat as it moves through the Florida Keys and into the
Gulf Sunday evening. Isaac poses a potential serious threat to portions of the
northern Gulf Coast Tuesday into Wednesday. All interests from Louisiana to
Mississippi, Alabama and the Florida Panhandle should watch the progress of
Isaac closely and begin to make preparations. Even areas as far west as extreme
southeast Texas should continue to monitor Isaac's progress in case a farther
west track materializes.
1120 AM CDT TUE AUG 28 2012
...RECONNAISSANCE DATA INDICATE ISAAC FINALLY ACHIEVES HURRICANE
STATUS...
(UPDATE: August 28th)
Hurricane Isaac is impacting travelers and the transportation industry causing
hundreds of flight cancellations and delays.
Isaac's
peak impacts are bearing down on the Gulf Coast beginning today.
Hurricane warnings continue for portions of the northern Gulf Coast,
including New Orleans, Biloxi and Gulf Shores as Isaac continues its
northwestward march. Hurricane watches are posted as far west as Morgan
City, La.
In
addition, a number of tropical storm warnings are in effect. A tropical
storm warning is in effect for the Florida Panhandle.
Even
as Isaac's center of circulation moves by, locally heavy rainbands can
be expected. Rainfall amounts over 10" are likely as Isaac slows down
immediately prior to, and after landfall, in southeast Louisiana,
southern Alabama, Mississippi and the western Florida Panhandle. In a
few cases, amounts exceeding 20" are possible. We have already seen in
excess of 9" of rain in some parts of the Florida east coast.
Expect
business closures and air, maritime, and ground transport disruptions
throughout the region. Prolonged power and telecommunications outages
are also possible.

(Update: August 29)
Hurricane
Isaac made landfall in Southeast Louisiana at 6:45 PM local time on
Tuesday. It made a second landfall overnight around 3 AM. This slow
moving storm is dumping rain on the entire area, knocking out power to
half a million people as 80 MPH winds continue to pound Louisiana.
Damage
is expected to be much higher than normal for this category hurricane,
it is still a Category One, because of the slow movement. In addition
to the storm surge, heavy rains, and flooding, there is a potential for
tornadoes to be spawned from the storm.
