After reaching Louisiana late Tuesday evening, Hurricane Isaac moved back out to sea - only to return to Louisiana shores around 2 am.

Isaac is slated to hit near Grand Isle, Louisiana, with winds of up to 100 mph, snapping trees and tearing down power lines.

The category 1 hurricane has already left nearly 165,000 homes and business thorough throughout Mississippi, Louisiana and Alabama without power.

At midnight Tuesday, the hurricane had slowed to a forward speed of 7 mph. It was forecast to slow even further over the next day or two as it drifts over the southeastern coast of Louisiana before heading inland, according to an advisory from the U.S. National Hurricane Center in Miami.

While much less powerful than Katrina in 2005, the storm drew intense scrutiny because of its timing - just before the anniversary of the hurricane that devastated that city, while the first major speeches of the Republican National Convention went on in Tampa, Fla., already delayed and tempered by the storm.

While many residents stayed put, evacuations were ordered in low-lying areas of Louisiana and Mississippi, where officials closed 12 shorefront casinos. One of the main concerns along the shoreline was storm surge, which occurs when hurricane winds raise sea levels off the coast, causing flooding on land.

A storm surge of 10.3 feet was reported at Shell Beach, Louisiana late Tuesday while a surge of 6.7 feet was reported in Waveland, Mississippi, the Hurricane Center said.

Ed Rappaport, the center's deputy director, said Isaac's core would pass west of New Orleans with winds close to 80 mph and head for Baton Rouge.

‘On this course, the hurricane will gradually weaken,’ Rappaport said. He said gusts could reach about 100 mph at times, especially at higher levels, which could damage high-rise buildings in New Orleans.

As Isaac neared the city, there was little fear or panic. With New Orleans' airport closed, tourists retreated to hotels and most denizens of a coastline that has witnessed countless hurricanes decided to ride out the storm.

‘Isaac is the son of Abraham,’ said Margaret Thomas, who was trapped for a week in her home in New Orleans' Broadmoor neighborhood by Katrina's floodwaters, yet chose to stay put this time. ‘It's a special name that means `God will protect us'.’

Officials, chastened by memories and experience, advised caution.

‘We don't expect a Katrina-like event, but remember there are things about a Category 1 storm that can kill you,’ New Orleans Mayor Mitch Landrieu said, urging people to use common sense and to stay off any streets that may flood.

Tens of thousands of people were told to leave low-lying areas, including 700 patients of Louisiana nursing homes, but officials decided not to call for mass evacuations like those that preceded Katrina, which packed 135 mph winds in 2005.

Isaac also promised to test a New Orleans levee system bolstered after the catastrophic failures during Hurricane Katrina. But in a city that has already weathered Hurricane Gustav in 2008, calm prevailed.

‘I feel safe,’ said Pamela Young, who settled in to her home in the Lower 9th Ward - a neighborhood devastated by Katrina - with dog Princess and her television. ‘Everybody's talking `going, going,' but the thing is, when you go, there's no telling what will happen. The storm isn't going to just hit here.’

Young, who lives in a new, two-story home built to replace the one destroyed by Katrina, said she wasn't worried about the levees.

‘Just so you all know, the hurricane has hit landfall and I think we should take this moment and recognize that fellow Americans are in its path and just hope and pray that all remain safe and no life is lost and no property is lost.'

Ann Romney

‘If the wind isn't too rough, I can stay right here,’ she said, tapping on her wooden living room coffee table. ‘If the water comes up, I can go upstairs.’

While far less powerful than Katrina, Isaac posed similar political challenges, a reminder of how the storm seven years ago became a symbol of government ignorance and ineptitude.

Political fallout was already simmering. Republican Gov. Bobby Jindal, who canceled his trip to the convention, said the Obama administration's disaster declaration fell short of the federal help he had requested, and asked for a promise to be reimbursed for storm preparation costs.

‘We learned from past experiences, you can't just wait. You've got to push the federal bureaucracy,’ Jindal said.

FEMA Administrator Craig Fugate said such requests would be addressed after the storm.

Obama promised that Americans will help each other recover, ‘no matter what this storm brings.’

‘When disaster strikes, we're not Democrats or Republicans first, we are Americans first,’ Obama said at a campaign rally at Iowa State University. ‘We're one family. We help our neighbors in need.’

In Tampa, the storm's landfall did not appear to affect prime-time coverage or the Republican National Convention speeches. One of the few mentions of the storm came in the opening remarks by Ann Romney, wife of the Republican nominee.

Outside, though, the streets of downtown Tampa were eerily deserted, a result of nasty weather from Isaac's outer bands, tight securities that blocked off streets and a delay in convention events because of fears the storm might target that side of the Gulf.

While politicians from both parties were careful to show their concern for those in the storm's path, Gulf residents and visitors tried to make the best of the situation on the ground.

In New Orleans' French Quarter, Hyatt hotel employee Nazareth Joseph braced for a busy week and fat overtime paychecks. Joseph said he was trapped in the city for several days after Katrina and helped neighbors escape the floodwaters.

‘We made it through Katrina; we can definitely make it through this. It's going to take a lot more to run me. I know how to survive,’ he said.

Maureen McDonald of Long Beach, Ind., strolled the French Quarter on her 80th birthday wearing a poncho, accompanied by family who traveled from three different cities to meet her in New Orleans to celebrate.

‘The storm hasn't slowed us down. We're having the best time,’ she said.

But farther east along the Gulf, veterans of past hurricanes made sure to take precautions.

At a highway rest stop along Alabama's I-10, Bonnie Schertler, 54, of Waveland, Miss., said she left her coastal home for her father's place in Alabama ‘because of the `coulds.'‘

Stock Up: Brigette Mooney shops for two-for-one frozen items at Seal's Marketplace on August 28, 2012 in Kiln, Mississippi. Store owner Michael Seal said he put all his frozen items on sale, both for the benefit of his local clients and also to reduce his stock ahead of the arrival of Hurricane Isaac to the Gulf Coast area and possible power outages

‘I just feel like the storm may stay for a few days and that wind might just pound and pound and pound and pound,’ said Schertler, whose former home in Waveland was destroyed by Hurricane Katrina. A slow storm is more dangerous, she said, ‘'cause it can knock down just virtually everything if it just hovers forever.’

Local officials, who imposed curfews in Mississippi's Harrison, Hancock and Jackson counties. And in Theodore, Ala., 148 people took refuge in a shelter at the town's high school by midday Tuesday, with minds focused as much on the past as on the present storm.

Charlotte McCrary, 41, at the shelter with husband, Bryan, and their two sons, 3-year-old Tristan and 1-year-old Gabriel, recalled the year she spent living in a FEMA trailer after Katrina destroyed her home.

Seven years later, the storm reminds her that she still hasn't gotten back to same place.

‘I think what it is,’ Bryan McCrary said, ‘is it brings back a lot of bad memories.’

The U.S. National Hurricane Center says the storm's center reached land at 6:45 p.m. in Plaquemines Parish, about 90 miles southeast of New Orleans.

Brandishing automatic assault rifles to ward off any threat of looting, the troops in military vehicles took up positions on mostly deserted streets. Their arrival came as driving rain and stiff winds battered the city's famous tourist district, The French Quarter, and its boarded-up storefronts.

White-capped waves formed in Lake Pontchartrain.

Earlier, the Army Corps of Engineers closed for the first time the massive new floodgate on the largest storm-surge barrier in the world, at Lake Borgne, east of New Orleans. In other preparations, oil production in the U.S. Gulf of Mexico nearly ground to a halt, and ports and coastal refineries curtailed operations as Isaac neared.

At 5 p.m. CDT (2200 GMT), the Hurricane Center said Isaac was centered about 105 miles southeast of New Orleans with top sustained winds of 80 miles per hour.

The storm, becoming better organized as it nears land, was traveling at a relatively slow 8 mph. That pace is a concern for people in its path since slow-moving cyclones can bring higher rainfall totals.

Isaac was about 370 miles wide and due to make landfall at the mouth of the Mississippi River within the hour. Heavy rains and big storm surges were also forecast for parts of Mississippi, Alabama and the Florida Panhandle.

Isaac spared Tampa, Florida, where the Republican National Convention began on Monday. But it forced party leaders to revamp their schedule. They may have to make further revisions so as not to be seen celebrating Mitt Romney's presidential nomination while Gulf Coast residents struggle through the storm.

President Barack Obama urged Gulf Coast residents to take cover and heed warning, saying, Now was 'not the time to tempt fate.' He issued emergency declarations for Louisiana and Mississippi earlier this week because of Isaac.

The president's stern warning comes as terrified New Orleans residents fear a repeat of the devastation inflicted by Hurricane Katrina after Isaac, which has now been declared a Category 1 hurricane, veers towards the Louisiana city.

Shop owners last night boarded up their businesses and the streets of the normally-bustling French Quarter are now eerily empty amid preparations for winds of over 100mph, which are predicted to hit the Gulf coast either this evening or tomorrow morning.

Although, the storm is currently generating surface gusts of 75mph, forecasters believe Isaac could pick up wind speed before it hits land in the same spot as Katrina, meaning roofs could be plucked from homes and cause extensive power outages in the city.

Few remaining: Some stayed in the city even though a hurricane warning has been issued for parts of the state east of Morgan City, which includes New Orleans area. A hurricane hasn¿t hit the Gulf Coast since Ike in 2008

But forecasters fear the greatest threat to the city will be the storm's onslaught of rain. Around New Orleans and Biloxi, Mississippi water could rise as high as six to nine feet, while coastal areas could be punished with up to 20 inches of rain, they said.

Hurricane warnings also extend across 280 miles from Morgan City, Louisiana to the Florida-Alabama state line. It is likely to to touch down seven years to the day that the 2005 disaster destroyed hundreds of thousands of homes, displaced a million people and left nearly 2,000 dead.

More than 50,000 Louisiana residents have been ordered to evacuate as Isaac, which has already ravaged parts of Haiti, the Dominican Republic and Cuba, picks up strength. A hurricane hasn’t hit the Gulf Coast since Ike in 2008.

Governor Bobby Jindal suggested anyone in low-lying parts of the state's coastal parishes leave their homes, while evacuations were also enforced in the lower areas of the Alabama coast, which faces flooding. In addition, 2,000 jail inmates have been moved out of Isaac's expected pat in Louisiana.

The next 24 hours would determine whether it brought the usual punishing rains and winds - or something even more destructive. Maps of the two storms' predicted paths highlight their similarities, with Isaac set to strike in almost exactly the same spot as Katrina.

On its way: A map, left, released on Monday shows the predicted path of Isaac, which is expected to hit Louisiana late on Tuesday night before sweeping north later this week. Its path can be compared to that of Hurricane Katrina's, right, which left nearly 2,000 people dead in 2005

Fortunately, Isaac, which is building up power as it picks up water over the Gulf, does not yet pack the deadly punch of Katrina, a Category 5 hurricane, with winds of over 157 mph. Forecasters initially said Isaac was going to become a Category 2, but now indicate it will not strengthen past Category 1.

In contrast, Katrina made landfall as a Category 3 hurricane and created a huge storm surge that burst the levees, causing wide scale flooding .

Last night Federal Emergency Management Agency officials insisted that the updated levees around the city are equipped to handle storms stronger than Isaac. Levee failures led to the catastrophic flooding in the area after Katrina.

'It's a much more robust system than what it was when Katrina came ashore,' said FEMA Administrator Craig Fugate.

After Katrina, a $14.5 billion flood defense system of walls, floodgates, levees and pumps was built to protect the city against a massive tidal surge like the one that swamped the city following the monster storm.

The floodgate that closed on Tuesday is 26 feet (8 meters) high and 1.8 miles (2.9 km) long, and was designed to prevent the Inner Harbor Navigation Canal from breaching its walls, as it did in 2005.

'It is difficult to realise that to the day - seven years after Katrina - another hurricane is headed our way,' Mississippi Governor Phil Bryant said. 'It is important for Mississippians to take this storm seriously and prepare for potential impact.'

In New Orleans, officials had no plans to order evacuations and instead told residents to hunker down and make do with the supplies they had.

'It's going to be all right,' said New Orleans Mayor Mitch Landrieu.

Isaac shifted West into the Gulf of Mexico after lashing the Florida Keys with strong winds and heavy rain over the weekend, causing Alabama, Florida, Mississippi and Louisiana to declare a state of emergency.

On Tuesday afternoon, Isaac was centered about 75 miles south-southeast of the mouth of the Mississippi River and was moving northwest at 10 mph, according to the National Hurricane Center in Miami. By 2 p.m. it was 135 miles southeast of New Orleans.

The crawling speed of 10 mph is a concern for people in the path of the storm since slow-moving cyclones can bring higher rainfall totals. The storm was about 370 miles wide.

Some Gulf residents started stocking up on supplies and securing their homes. In New Orleans, long lines formed at some gas stations and in Gulfport, Mississippi, people crowded supermarkets to buy bottled water and canned food.

'I sense a high level of anxiety,' said New Orleans Mayor Mitch Landrieu. 'The timing, as fate would have it, on the anniversary of Katrina has everybody in a state of alertness, but that is a good thing.'

Despite hurricane warnings extending more than 330 miles from Louisiana to Western Florida, the greatest test will be for New Orleans. Louisiana has set up shelters and stockpiled more than a million packaged meals, 1.4 million bottles of water and 17,000 tarps.

Jindal said more than 4,000 National Guardsmen will be mobilized in case of emergency. He added that President Obama called him on Monday to say that the governor's request for a pre-landfall federal disaster declaration had been approved, which would provide federal funding for any damage.

'We are going to need help after the storm as well,' Jindal said. 'This is not going to be done just after the storm makes landfall or even just after the storm leaves Louisiana.'

Brandishing automatic assault rifles troops in military vehicles took up positions on mostly deserted streets in New Orleans, keeping an eye out for potential looters.

ISAAC: PUSHING UP GAS PRICES

As Tropical Storm Isaac barrels towards the Gulf Coast, energy companies have scrambled to evacuate workers from oil and natural gas platforms, bringing production to a halt.

The Gulf accounts for more than 20 per cent of U.S. oil production and more than 40 per cent of refining. Experts estimate a 75 per cent to 90 per cent shut down of production.

As plants close, it could send gasoline prices spiking across the country just ahead of the U.S. Labor Day holiday, analysts believe.

The average price per gallon of regular unleaded gasoline in Florida has already risen 9 cents to $3.75. Across the country, gas has increased an average of 3 cents per gallon to $3.73 per gallon in the last week.

AAA motorist group told the Orlando Business Journal that it's too early to tell just how long Isaac will delay Gulf oil production - but the precautionary shutdowns are have already caused a loss of 2 to 3 million barrels of oil.

Isaac's westward track meant the worst of its weather will miss Tampa, where the Republican National Convention was expected to open its four-day meeting on Monday but official events were delayed until Tuesday because of the storm.

The storm's potential for destruction was not lost on Alabama farmer Bert Driskell, who raises peanuts, cotton, wheat, cattle and sod on several thousand acres near Grand Bay, in Mobile County. 'We don't need a lot of water this close to harvest,' Driskell said.

But a lot of other residents were relaxed about the looming storm.

'I'm not all that concerned about the storm. It's still a Category 1,' Charles Neeley, a 69-year-old contractor overseeing workers covering the windows of a CVS drugstore in New Orleans, said. 'We usually ride out ones and twos and get the hell out for threes and fours.'

Nonetheless, Neeley said he had stocked up on food and water at home and fuel for his generator.

'Our flights were canceled so we're going to be here,' said Karen Foley, a 23-year-old tourist who had planned to travel home to New Jersey with a friend. 'We are just hoping the city doesn't get hit again. It doesn't deserve it.'

Louis Armstrong New Orleans International Airport said there are no flights scheduled for Tuesday and the airport will not be used as an evacuation shelter. People will not be allowed to stay in the terminal during the storm, the airport said in a statement Monday, ABC reported.

In south Florida, winds from Isaac forced cancellations of hundreds of flights in and out of Miami, Fort Lauderdale and other south Florida airports across the weekend. Miami Mayor Carlos Gimenez reported more than 500 cancellations affecting Miami International Airport alone.

The U.S. National Hurricane Center issued a hurricane warning for the northern Gulf Coast from Louisiana to the Florida Panhandle on Sunday.

Tropical force winds from the massive storm stretched across 400 miles (644 km), with rain bands extending even further, said NHC meteorologist David Zelinsky. It means Isaac could cause significant damage even in places where it does not pass directly overhead.

'It certainly is a large storm,' he said, noting that wind gusts of 60 mph (100 kph) had been detected as far apart as Key West and Palm Beach.

The storm will likely pick up strength from the warm, open waters of the Gulf of Mexico and strike as a dangerous Category 2 hurricane somewhere between New Orleans and the Florida Panhandle on Wednesday.

Isaac has brought havoc to the Caribbean already, killing at 22 people in Haiti, Cuba and the Dominican Republic and downing trees and power lines.

There were scattered power outages from Key West to Fort Lauderdale affecting more than 6,000 customers, and flooding occurred in low-lying areas.

It had officials worried enough in Tampa that they shuffled around some plans for the Republican National Convention, cancelling the first day of the event.

HURRICANE KATRINA: CLEANING UP THE DEVASTATION

On August 29, 2005, Hurricane Katrina lashed New Orleans, wiping out hundreds of thousands of homes, submerging 80 per cent of the city in flood water and leading to the deaths of 1,836 people.

The Federal Emergency Management Administration (FEMA) was lambasted for its slow response and the chaos following the disaster. Even though workers were in the region, many could not give direct assistance and could only report on the situation. They were overwhelmed by the sheer number of victims and their communication and transportation struggled with the severe flooding. Within three days, National Guard and active duty troops were sent to the area.

More than one million people left the region due to the destruction and the devastated economy, making it the largest displacement in U.S. history.

The government sought $105 billion for reconstruction and repairs for the region. A week after the hurricane, power began surging back, service relief ships began docking and water and sewage was gradually restored.

While some were slow to arrive, relief agencies eventually swarmed New Orleans and remained for months following the disaster. Two months after the hurricane, charities like the Red Cross were a mainstay - setting up relief centers around the city that provided hot meals, food, bottled water and other supplies like diapers. Volunteers, from groups such as Habitat for Humanity, helped repair homes.

For years following the disaster, debris was removed and homes were rebuilt, but the population still remains around two thirds of what it was before the hurricane struck.

'Our first priority is ensuring the safety of delegates, alternates, guests, members of the media attending the Republican National Convention, and citizens of the Tampa Bay area,' party chairman Reince Priebus said in an emailed announcement that followed private conversations involving presidential candidate Mitt Romney's campaign, security officials and others.

Nearly $20million was spent to prepare the scene for the political pow wow, with up to 300 people working round the clock to refurbish the venue, home to the Tampa Bay Storm arena football team and the town’s NHL team, the Tampa Bay Lightning.

Forecast models show Isaac won't hit Tampa head-on, but the storm will still likely lash the city with rain and strong winds just as the convention ramps up. Protests started in full force on Sunday afternoon, and demonstrators have vowed that they will make their presence known rain or shine.

Former Massachusetts Gov Mitt Romney will officially be nominated as the Republican Party's presidential candidate on Tuesday, one day later than originally planned.

His nationally-televised acceptance speech will be on Thursday night as originally planned.

Tuesday evening's program includes remarks by Ann Romney, the candidate's wife, as well as by New Jersey Gov Chris Christie, previously announced as the keynote speaker.

Ryan will deliver his acceptance speech Wednesday evening in prime time in the eastern part of the United States, and Romney's speech dominates the final night.

Donald Trump, who was originally scheduled to speak on Monday, was dropped from the program altogether in the weather-related reshuffling.

Other top Republicans are thinking about skipping out on the convention as Isaac approaches. Among them is Louisiana Gov Bobby Jindal, who earlier on Sunday declared a state of emergency for the Bayou State, and declared that he would not leave if it was hit by Isaac.

Alabama Gov. Robert Bentley has canceled his trip to the convention because of Isaac, and Florida Gov. Rick Scott also gave up his speaking engagement.

Officials were handing out sandbags to residents in the Tampa area, which often floods when heavy rainstorms hit. Sandbags also were being handed out in Homestead, 20 years after Hurricane Andrew devastated the community there. Otherwise, however, convention preparations were moving ahead as usual.

Oil companies scrambled out of the path of Tropical Storm Isaac, withdrawing offshore workers and cutting oil and gas production in the Gulf of Mexico.

By mid-day Sunday, the U.S. government said that daily oil production in the Gulf was down 24 per cent and natural gas production was off 8 per cent.

Noting that the storm was moving west and threatening to grow more powerful, energy giant BP evacuated all its installations and temporarily halted production in the Gulf Sunday.

Earlier, it had pulled workers from its massive Thunder Horse platform in the eastern Gulf.

Royal Dutch Shell is withdrawing all workers and suspending production in the eastern Gulf. It is pulling out all but essential personnel and cutting production in the central Gulf.

Apache Corp., a Houston oil services company, is withdrawing 750 workers and contractors from its installations in the eastern Gulf. It is also cutting production of oil and natural gas.

Other energy companies have also been evacuating their platforms and rigs in the Gulf. Murphy Oil Corp., based in El Dorado, Arkansas, said Sunday that it is pulling out all workers and suspending operations in the Gulf.

The storm could spur short-term shut-downs of 43 per cent of U.S. offshore oil capacity and 38 per cent of its natural gas output, according to forecasters at Weather Insight.

Isaac has already left a trail of suffering across the Caribbean.

The tropical storm bore down on Haiti's southern peninsula and on Cuba on Saturday, leading to 22 deaths and dumping torrential rain on a nation still trying to recover from the horrific 2010 earthquake.

Isaac's rain and winds lashed Haiti's southern coast on Saturday, flooding parts of the capital Port-au-Prince and ripping through flimsy resettlement camps that house more than 350,000 survivors of the 2010 earthquake.

A 10-year-old girl was killed in Port-au-Prince when a wall fell on her and a woman in the southern coastal city of Jacmel was crushed to death when a tree fell on her house, government officials said.

At a tent camp in the seaside slum of Cite Soleil, corrugated plastic shacks were broken apart and water gushed in.

'We had never seen anything like this. Everyone fled to the church, but I didn't want to leave my home. All my things are wet,' said Edeline Trevil, 47, who survived with her cat. 'I'm cold! I've been wet since last night,' the shoeless woman added.

The storm caused power outages and flooding and blew off roofs as it moved across the hilly and severely deforested Caribbean country. Winds had died down by Saturday afternoon but forecasters said rains would continue in Haiti.

Damage had so far been less than feared, said George Ngwa, Haiti spokesman for the United Nations Office of Coordination of Humanitarian Affairs.

'We don't have any serious reports of major flooding or mudslides so far,' he said.

In Haiti, the United Nations mission said it was prepared to distribute food and emergency supplies for more than 300,000 people, and 10,000 U.N. troops, including several engineering units, stood ready to clear roads for emergency response teams.

The government and aid groups tried to evacuate thousands of tent camp dwellers on Friday but many Haitians chose to remain in their flimsy, makeshift homes, apparently fearing they would be robbed, said Bradley Mellicker, head of disaster management for the International Organization for Migration (IOM).

Haitian Prime Minister Laurent Lamothe urged people to avoid crossing rivers and to stay calm, saying 'panic creates more problems.'

He said the government had set aside about $50,000 in emergency funds and had buses and 32 boats on standby for evacuations.

In Port-au-Prince, a city of some 3 million ringed by mountains, people went to work as usual Friday, but commercial banks closed at noon and some residents took precautions as the sky darkened, rain fell and the wind picked up.

'Just in case this gets very bad - the sky is turning gray - I'm making sure we have enough food in the house,' said 25-year-old Joanne Dorville as she carried home rice, sardines, black beans and cooking oil that she had purchased in a street market.

Hurricane Isaac sidestepped New Orleans on Wednesday, sending the worst of its howling wind and heavy rain into a cluster of rural fishing villages that had few defenses against the slow-moving storm that could bring days of unending rain.
Isaac arrived exactly seven years after Hurricane Katrina and passed slightly to the west of New Orleans, where the city’s fortified levee system easily handled the assault.
The city’s biggest problems seemed to be downed power lines, scattered tree limbs and minor flooding. One person was reported killed, compared with 1,800 deaths from Katrina in Louisiana and Mississippi. And police reported few problems with looting. Mayor Mitch Landrieu ordered a dusk-to-dawn curfew just to be sure.
In Plaquemines Parish, a sparsely populated area south of the city that is outside the federal levee system, dozens of people were stranded in flooded coastal areas. The storm pushed water over an 18-mile levee and put so much pressure on it that authorities said they will breach the floodwall to relieve the strain. (AP)
