[Updated 11:11 p.m. ET] Hurricane Isaac is "producing a dangerous storm surge" along the northern Gulf Coast, the National Hurricane Center said in its 11 p.m. ET update. Flooding from heavy rainfall will follow the storm surge, the NHC said.
At 11 p.m. ET, the storm's center of circulation was about 75 southeast of Houma, Louisiana, or 75 miles south-southeast of New Orleans, still moving at 8 mph with 80 mph maximum sustained winds.
[Updated 11:01 p.m. ET] Designer John Nelson created this fascinating and oddly beautiful visualization of every hurricane recorded since 1851. It's reproduced by Fast Company.
The image takes some getting used to, as it employs a southern polar projection; that is, Antarctica is in the center of the picture, with the other continents extending away from it. Hovering your mouse over the map enlarges an area so you can see greater detail.
Nelson created the map using data from NASA Visible Earth and NOAA International Best Track Archive, according to Fast Company.
[Updated 10:45 p.m. ET] Tropical Depression 11 rapidly intensified Tuesday evening and became the 11th named storm of the 2012 Atlantic hurricane season, Tropical Storm Kirk, the National Hurricane Center said. Kirk is located in the middle Atlantic and is not likely to become a threat to land.

[Updated 10:08 p.m. ET] CNNWeather meteorologist Jim Hennen says that unlike many other hurricanes that move inland and weaken quickly, Isaac could actually strengthen over the Louisiana bayou and hold its intensity as a hurricane through much of the night. It should begin to slowly lose intensity later tonight as it moves farther inland.
Storm surge will continue to be a threat through the night, and flooding is likely to be a major problem as the storm slows as it tracks inland, Hennen says. Up to 20 inches of rain will fall over the Gulf Coast region in the coming days.
Storm surge flooding of up to 12 feet will continue through evening, before diminishing overnight. The peak storm surge and winds will occur in New Orleans from now until daybreak tomorrow, and than will begin to slowly subside.
The storm will also make a direct hit on Baton Rouge late Tuesday and into Wednesday.
Expect power outages to spread overnight as the storm knocks down trees and utility lines.
Rain from the storm extends over 1,200 miles from the Texas-Louisiana line all the way to the Carolinas.
Over the next several days the remnants of Isaac will move slowly northward, bringing widespread heavy rains of 4 to 6 inches to the exceptional drought areas from Arkansas into Missouri, Illinois, Indiana, and Ohio.

[Updated 8:05 p.m. ET] Isaac has made landfall in southeastern Louisiana, the National Hurricane Center said.
[Updated 7:45 p.m. ET] The Army Corps of Engineers said it has closed the Bayou Verret floodgate in Louisiana and will close floodgates on Bayou Segnette on Wednesday morning because of strong wind and high tides associated with Hurricane Isaac, CNN affiliate WDSU reports.
The gates are closed when water in the canal reaches two feet above sea level and is rising, preventing surges from entering the canals. The Army Corps said the gates will remain closed until the threat from Isaac has passed.
Earlier, the Corps closed the Seabrook Floodgate Complex for the first time due to a storm event. The closure follows the closing of gates at the Inner Harbor Navigation Canal (also known as the Industrial Canal) and Bayou Bienvenue earlier today.
The Seabrook Floodgate Complex is located at the north end of the Industrial Canal, just south of Lake Pontchartrain.
[Updated 7:16 p.m. ET] At 7 p.m. ET, the National Hurricane Center reported Hurricane Isaac was about 15 miles south-southwest of the mouth of the Mississippi River and 95 miles southeast of New Orleans. It was moving to the northwest at 8 mph and had maximum sustained winds of 80 mph. Winds of 74 mph or greater extend up to 60 miles out from the storm's eye.
Winds are significantly stronger at higher levels. A wind gust of 106 mph was reported at an oil rig off the Louisiana coast at an elevation of 279 feet - the equivalent of the 28th floor of a building, the NHC said.
Isaac is expected to strengthen slightly before making landfall sometime in the next few hours, then lose strength as it moves over land.

“The few vessels that are still underway need to reach safe moorings as soon as possible,” said Capt. Peter Gautier, commanding officer of Sector New Orleans. “This storm should not be taken lightly."
During the weekend, the Coast Guard required ships, tugboats, and barges to move upriver to more secure mooring locations and began the evacuation of canals adjacent to New Orleans.
Coast Guard helicopters and small boats have been moved to safe locations and will be positioned for post-storm operations.
[Updated 6:18 p.m. ET] Alabama Gov. Robert Bentley reminds folks that during high-volume periods, it's easier to get a text through than a voice call:

[Updated 2:56 p.m. ET] An outer rain band of Isaac has been sheared from the northeastern flank of the circulation and is moving very slowly over the Carolinas, hundreds of miles from the storm's center. As much as 3.5 inches of rain fell in just 90 minutes in Charleston, South Carolina, and is causing major flooding in some locations.
"We were stranded and had to be rescued ourselves," said Tracy Amick, spokesperson for Charleston County. "Our car had water coming through the doors. It's ridiculous right now. There are trash cans floating down the street, cars stuck, people trying to get through these flooded streets on bicycles ..."
A flash flood warning for Charleston has been extended until 5:30 p.m. ET as some roads have become impassible and flood waters will be very slow to recede with high tide approaching.
[Updated 2:42 p.m. ET] Extensive efforts have been made in the past seven years to better protect the New Orleans area from hurricane damage.

The men are sought in connection with the looting of several boats that were docked in Slidell on Monday night, the paper reported.
"If someone loots a business or home in St. Tammany Parish, the full force of this sheriff's office will be dedicated to finding them, putting them in jail, and making sure they are charged to the full extent of the law," Sheriff Jack Strain said in a news release.
[Updated at 1:50 p.m. ET Tuesday] The National Hurricane Center's 2 p.m. ET update says Isaac looks much the same as it did at 11:20 a.m. It remains a hurricane with winds of 75 mph.
It is now about about 55 miles south-southeast of the mouth of the Mississippi River and about 135 miles southeast of New Orleans. It continues to move northwest at 10 mph.
A hurricane remains in effect from east of Morgan City, Louisiana, to the Mississippi-Alabama border, and a hurricane watch is in effect between Morgan City and Intracoastal City, Louisiana, the hurricane center says.

[Updated 1:42 p.m. ET Tuesday] The U.S. Coast Guard is searching the coast of Pensacola, Florida, for a missing jet skier whose wife reported him missing Monday night.
As Hurricane Isaac builds, "the increasing winds and seas make search conditions extremely difficult and unsafe for aircrews," Coast Guard spokesman Timothy Williams says. "As Isaac approaches, Coast Guard aircrews will temporarily suspend their search efforts until the storm passes and weather conditions become safe enough to resume the search."
[Updated 1:38 p.m. ET Tuesday] Alabama Attorney General Luther Strange has a succinct warning for those who might try to capitalize on the storm: Don't even think about it.
A state of emergency has been declared, and the state's price-gouging and looting laws are in full effect, Strange told CNN affiliate WKRG-TV.
Gougers can be fined up to $1,000 and risk losing their business licenses, while looters could be slapped with a Class C felony, up to 10 years in prison and a fine of up to $15,000, WKRG reports.
“I urge our citizens to be cautious of those who would prey upon them through crimes such as price gouging, looting and home repair fraud. I warn the criminals that if they do so, they will be punished," Strange said.
[Updated 1:15 p.m. ET Tuesday] Angela Young, a resident of New Orleans East, which was hit particularly hard by Katrina and is still struggling to recover, says she has plenty of supplies - including food, batteries and non-perishable food - and intends to stay at home during Isaac.
She's paying special attention to announcements from parish officials and the mayor.
"They're saying that we're going to be OK, so I trust that we're going to be fine," she said.
[Updated 1:09 p.m. ET Tuesday] Harrison County, Mississippi, which already has issued a curfew from this evening through Wednesday morning, is now ordering evacuations in low-lying areas, CNN affiliate WLOX-TV reports.
"Our first priority is the safety of our citizens. We are concerned about anyone who might be stranded without access to any help," Harrison Emergency Management Director Rupert Lacy told the station.
"Please realize that if you choose to remain in an area that's under a mandatory evacuation, our responders may not be able to reach you in case of a medical emergency or unexpected flooding," he added. "Please take the safest course for the duration of this storm."

[Updated 12:46 p.m. ET Tuesday] Richard Knabb, director of the National Hurricane Center, reminds Gulf Coast residents that despite concerns about the Isaac's winds, a storm's "water components are often the more deadly and sometimes the more damaging."
With potential storm surge of 6 to 12 feet in some areas and Isaac threatening to dump up to 20 inches of rain as it slows down over land, there is an increased threat of inland flooding in the next few days, Knabb said.
"It's not just going to be a coastal event," he said.
[Updated 12:38 a.m. ET Tuesday] Tropical storm-force winds are already battering areas as far out as 185 miles from Isaac's eye, including the coastal areas of Louisiana, Mississippi and Alabama, the National Hurricane Center says.
The storm, which is presently moving at 10 mph, is expected to slow down, which could mean bad news in some areas, as it will allow Isaac to dump heavier rains.
The hurricane center says 14 inches of rain could fall on some locales, while parts of southeast Louisiana, southern Mississippi, southern Alabama and the Florida Panhandle could see up to 20 inches.
[Updated 12:31 p.m. ET Tuesday] According to an updated statement from the National Hurricane Center, issued at 12:20 p.m. ET, reports from an Air Force craft indicate Isaac's winds have surpassed the 74-mph threshold necessary to classify a storm as a hurricane.
The storm remained about 160 miles southeast of New Orleans and was moving northwest at about 10 mph, according to the updated statement. The central pressure had lowered to 975 mb, slightly below the 11 a.m. ET reading of 976 mb. Lower pressure means stronger winds.
[Updated 12:26 p.m. ET Tuesday] Isaac is now a Category 1 hurricane, with maximum sustained winds of 75 miles an hour, the National Hurricane Center says.
[Updated 12:24 p.m. ET Tuesday] In Biloxi, Mississippi, the nasty memories of destruction seven years ago is prompting many residents to evacuate, despite projections that Isaac will not be nearly as strong as Katrina.
Residents are packing up and leaving town, schools and government offices are closed until Thursday and police and emergency responders are out"in full force," according to CNN affiliate WPLG-TV. Many houses have already been boarded up, and some residents were seen sawing wood and drilling down boards over their windows, the station said.
David Wallis, who lived through Katrina, picked up his and his wife's prescriptions before leaving town. He recalled how difficult it was to obtain the most basic of goods after Katrina.
“That was a big issue last time: water and ice. There was no water and ice for days. You can do without the electricity and stuff for a few days, but gotta have that water," he told WPLG.
[Updated at 12:12 p.m. ET Tuesday] In case you missed it earlier, CNN has updated its checklist of things you should have on hand as you prepare for the storm.

[Updated 11:53 a.m. ET Tuesday] Shrimper Dean Blanchard says he will ride out Isaac from his specially built home in Grand Isle, Louisiana, which has been through a few hurricanes in the past.
He says it's easier to stay put than to leave and try to come back when police are working to protect residents not only from the aftereffects of the storm but also looters.
"We expect a little wind today, and we'll probably get a little rain late on and get ready for tonight, see what Mother Nature got ins store for us," he said.
[Updated 11:43 a.m. ET Tuesday] Alabama Emergency Management Agency Director Art Faulkner says the state has been preparing for Isaac for a week, and officials will be on the coast later Tuesday to make sure first responders have everything they need to keep residents safe.

[Updated 11:06 a.m. ET Tuesday] The National Hurricane Center says Isaac is about 165 miles southeast of New Orleans and about 80 miles south-southeast of the mouth of the Mississippi River. It is moving northwest at about 10 mph, and the storm's center is on track to hit Southeastern Louisiana on Tuesday evening.
The storm should be a hurricane by then, the center says, and will slowly weaken after making landfall. As of 11 a.m. ET, the central pressure remained at 976 mb, the same as it was at 8 a.m. ET.
[Updated 11 a.m. ET Tuesday] Tropical Storm Isaac has yet to reach hurricane strength, according to the National Hurricane Center's 11 a.m. ET advisory. The storm has winds of about 70 mph.
[Updated 10:49 a.m. ET Tuesday] President Barack Obama called on Gulf Coast residents to prepare for Tropical Storm Isaac, which is close to hurricane status as it heads toward land.
"Now's not the time to tempt fate," he said. "Now's not the time to dismiss official warnings. You need to take this seriously."
[Updated 10:38 a.m. ET Tuesday] Are you awaiting Isaac's arrival? If so, please send your photos, videos and stories to iReport and let us know what you're seeing. Thanks!
[Updated 10:31 a.m. ET Tuesday] iReporter Eileen Romero is staying put in New Orleans for Isaac, just as she did for Katrina seven years ago. She shot several photos Monday of people boarding up their businesses and homes and said Tuesday that there were long lines at the gas stations that still had gas to sell.
Anxiety is high in the Crescent City as some prepare to stay and others attempt to evacuate, she said. The Wednesday anniversary of Katrina's landfall doesn't help.
"At the forefront of people's minds is the damage sustained during the catastrophic flooding after the levee failures following Hurricane Katrina," she said. "Talk about PTSD."
While the Corps of Engineers insists the levees are stronger than they were seven years ago, Romero has her doubts given that "inherent engineering flaws and governmental incompetence is what led to the levee failures in the first place."
Despite her lack of faith in its leaders, she loves her city, she said.
"NOLA is home, and there is no place like it in the world," she said.
[Updated 10:17 a.m. ET Tuesday] The Mississippi Gaming Commission has notified Biloxi and Gulfport casinos that they need to get gamblers off the floor within the next 45 minutes. Gaming floors should be shut down by 4 p.m. CT, the commission says.

James Kaplan told CNN affiliate WSVN-TV that he was headed to work when the tree - which is estimated to be about 50 years old - hit the driver's side roof of his car, just above the windshield.
The tree smashed the windows, broke a mirror and buckled the frame of the car, but Kaplan's only apparent injuries were scratches on his left ear, even though he said the roof of the car made contact with his head.
Kaplan joked with the WSVN crew that came to his house: "I kind of thought when you were at the door with the camera at the door, it was Mercedes wanting to do a commercial."
[Updated 9:58 a.m. ET Tuesday] The New Orleans Saints have already left town ahead of their midweek preseason game, their last before the regular season begins. According to the team's website, the Saints left at 5:30 p.m. CT Monday for Cincinnati, Ohio, where they will practice Tuesday before heading to Nashville, Tennessee, on Wednesday.
The Saints play the Tennessee Titans on Thursday evening and will depart for New Orleans following the game, the team said.
[Updated 9:53 a.m. ET Tuesday] As the Southeast United States deals with Isaac, Typhoon Bolaven is bringing high winds and torrential rains to the Korean Peninsula. Already, several people are missing, fishermen have been killed, scores of flights have been canceled and almost 200,000 homes are without power.
[Updated 9:38 a.m. ET Tuesday] To elaborate on the mayor's remarks, New Orleans' levees have seen $10 billion in improvements since 2005, and the pump stations have backup generators in case of power outages. One station is the biggest in the world, capable of moving 150,000 gallons of floodwater per second.
"This is the best system that the greater New Orleans area has ever seen," said Col. Ed Fleming of the Army Corps of Engineers.
For more specifics, here is a detailed explanation of how the system works.
[Updated 9:27 a.m. ET Tuesday] As of Tuesday morning, it was too late to evacuate New Orleans, Mayor Mitch Landrieu said, but many residents are expressing confidence that Isaac will not bring the destruction that Katrina's 125-mph winds wrought years ago. Plus, residents said, law and order in the city has improved.
"We're confident that the work we've done in the last few years makes us fully capable of handling this type of storm," the mayor said.
Jackie Grosch had to rebuild her home in Louisiana after Hurricane Katrina, but the St. Bernard Parish resident said she was going to wait Isaac out. She and her family had a generator, weather radio and life jackets on hand "just in case."
She expressed confidence in the new levees near her home.
"I don't know if it's going to be a true test because they're saying it's not going to be that bad. But you never know what bad is. We didn't think Katrina was going to be bad, either," she said.
[Updated 9:06 a.m. ET Tuesday] Isaac's center was located about 105 miles south-southeast of the mouth of the Mississippi River, according to the National Hurricane Center's last advisory at 8 a.m. ET. The central pressure was 976 mb, just slightly lower than it was at 7 a.m. ET. The lower the pressure, the stronger the winds around the eye of the storm.
The hurricane center is predicting storm surges of 6 to 12 feet in Southeast Louisiana and Mississippi, 4 to 8 feet in Alabama, 3 to 6 feet in south-central Louisiana and along the Florida Panhandle and 1 to 3 feet along Florida's west coast to the Apalachee Bay.

[Updated 7:53 a.m. ET Tuesday] Isaac has yet to reach hurricane strength, the National Hurricane Center said in its 8 a.m. ET advisory. The storm's maximum sustained winds were at 70 mph, just below the Category 1 hurricane speed of 74 mph.
[Updated 7:25 a.m. ET Tuesday] A survey for the motorist group AAA showed that the national price for a gallon of regular gas crept up 0.6 cent to $3.756 overnight as Gulf coast oil and refining facilities were closed in anticipation of Isaac's landfall, CNNMoney reports.
Steeper prices increases were recorded in the Gulf states preparing for the storm, with gas jumping 2.5 cents to $3.642 a gallon in Louisiana, a little more than 2 cents to $3.563 in Mississippi, and 1.3 cents to $3.581 in Alabama.
[Updated 7:09 a.m. ET Tuesday] Some inland areas could see as much as 20 inches of rain from Isaac, said Richard Knabb, director of the National Hurricane Center. The storm's slow movement could make the rainfall worse and increase chances for flooding, he said.
[Updated 7:01 a.m. ET Tuesday] Isaac has developed an eye in the last few hours, indicating the storm is becoming more organized, and the central pressure is now down to 977 mb, which is the lowest pressure that has been recorded during Isaac’s life cycle. The latest intensity forecast indicates Isaac could become a Category 1 hurricane this afternoon with winds sustained at 80 mph.
[Updated 6:48 a.m. ET Tuesday] Isaac is threatening Louisiana agriculture, including a record corn harvest, according to the LSU AgCenter.
One third of that crop is still in the fields, said LSU AgCenter feed grain and cotton specialist John Kruse, because drought conditions have brought down Mississippi River water levels, meaning barges that transport the grain can't be fully loaded.
“Everyone was bringing in more corn than normal, and there was just nowhere to put it,” Kruse said in a press release. “So things slowed down dramatically.”
Cotton is also under threat, Kruse said in the release, with much of the crop two weeks to a month away from picking.
“This storm could really tear up our cotton crop," Kruse said.
Losses are also expected in the state's soybean and sugarcane crops, the center said.
[Updated 6:30 a.m. ET Tuesday] Isaac has closed at least six casinos in Louisiana, CNN affiliate WDSU reports.
[Updated 6:22 a.m. ET Tuesday] Tropical Storm Isaac is curtailing oil production along the Gulf of Mexico and threatening refineries, which could send gasoline prices up another 10 cents in the coming week, CNNMoney reports.
[Updated 6:15 a.m. ET Tuesday] Louis Armstrong New Orleans International Airport is closed Tuesday with no flights scheduled.
The airport said on its website it will not be open as an evacuation shelter and only passengers with tickets will be allowed to use parking garages on Tuesday.

Who's trying to wake me up.
It's a good thing our honorable commander in chief, Mr. Barrack Obama, is handling this one. The last one was during that other guy's administration, the head of FEMA was crying that he didn't feel like going to work anymore. Mr. Obama sir, we salute you!!
You can go back to sleep. Everything is under control. Our commander in chief, Mr. Barrack Obama,has everything under control.

That is one of the longest articles I've seen in a long time. After a while I found it incredibly irritating that all the "updates" were printed in reverse order, and, as we begin at the top, this would require us to zoom down to the bottom before beginning our perusal of this immense collection of updates in a hard-to-read format.
Well done, CNN. I found it easier to shoot right to the bottom and leave a snarky complaint/comment than read the whole bs.
I mean, really!!
What is your major malfunction here?

I was schocked to read several comments last week wishing that the hurricane would wipe out Haitians. What a heartless thing to wish for other human beings! Well, for those who were hoping that Isaac would just be another punishment sent from God JUST for emporished Haiti, God is also God for the needy: Isaac was not event a hurricane yet when it passed over Haiti. There is never anything to rejoice about when others are hurt by natural disasters: they happen anywhere, to any nations, no matter how rich, poor, developed or under-developed. We should all pray for those affected.
Im going to build a house on top of a volcano! And when my house is destroyed and i am badly burned, i am going to demand that all you people and the government come bail me out! Then i will collect my money from the insurance companys and government (tax payers) and i will rebuild in the same location. And I Will be expecting you all to be helping me next year as well!! ect... ect... ect... p.s. i hope George W. Bush will not torture me with his weather machine while i am living on this volcano
Many thanks for the information.
