Hurricane Isaac bears down on New Orleans, Louisiana Hurricane Isaac moving slowly across New Orleans
(about 2 hours later)
Thousands of people have fled the US city of New Orleans as Hurricane Isaac makes its slow approach. New Orleans is hunkering down as Hurricane Isaac pummels the city with strong winds and drenching rain.
The hurricane will hit the Louisiana city exactly seven years after it was devastated by Hurricane Katrina, but it is a much less powerful storm. The hurricane is drenching the Louisiana city exactly seven years after the devastating Hurricane Katrina, but is much less powerful.
The city has closed its new floodgates in a bid to protect it from the effects of high waters brought by sustained winds of up to 80mph (130km/h).The city has closed its new floodgates in a bid to protect it from the effects of high waters brought by sustained winds of up to 80mph (130km/h).

The wind has started to build up and the rain is lashing down in the French Quarter of New Orleans as the narrow, high-sided streets amplify the wind speed. Debris is starting to be tossed around on Canal Street, as roadworks are being pulled apart by the high winds and trees are shaken almost from their roots. There are now reports of serious flooding and people stranded by rising waters in the Braithwaite area, just across the Mississippi river from metropolitan New Orleans.
Some areas have lost power already. The streets have been cleared of all but the foolhardy - and the journalists with TV satellite trucks parked in the lee of buildings. Waiting out the storm
The timing of the storm has brought so much attention to this city devastated by Hurricane Katrina when it struck seven years ago. At 08:00 local time, the centre of the storm was 40 miles south of New Orleans and moving inland at about 6 mph, according to the href="http://www.nhc.noaa.gov/text/refresh/MIATCPAT4+shtml/291256.shtml" >US National Hurricane Center (NHC).
I sat through the storm then in a hotel room and watched as 4x4s were pushed along roads with the force of the wind, wrought-iron staircases ripped off buildings and windows were blown out. The slow-moving storm could take 12 hours to travel as far as Baton Rouge, a town 70 miles to the north-west of New Orleans.
The wind speeds so far are just a third of those during Katrina but it's the volume of water falling and the storm surge being driven onshore which threaten homes - and those who have decided to sit out the storm. Officials are urging residents who have not evacuated to stay in place until high winds dissipate.
Many people have chosen to stay - boarding up their doors and windows and settling in for a long night, hoping Hurricane Isaac will be kinder to their city. "We have resources ready to go, but until the winds come down, we're really asking people, if you're not somewhere that's dangerous, stay where you're at unless you're told to evacuate," Federal Emergency Management Agency director Craig Fugate told CNN.
At 06:00 local time, it was 50 miles south of New Orleans and moving inland at about 6 mph, according to the href="http://www.nhc.noaa.gov/text/refresh/MIATCPAT4+shtml/291054.shtml" >US National Hurricane Center (NHC). About a half-million people were without power in Louisiana as of Wednesday morning, and two highways north of New Orleans were no longer passable because of storm surge.
Isaac killed at least 24 people as it passed over Haiti and the Dominican Republic earlier this week.Isaac killed at least 24 people as it passed over Haiti and the Dominican Republic earlier this week.
It has also caused significant flooding and damage across the Caribbean and forced a day's delay to the start of the Republican party's congress in Tampa, Florida.It has also caused significant flooding and damage across the Caribbean and forced a day's delay to the start of the Republican party's congress in Tampa, Florida.
'I feel safe''I feel safe'
Tens of thousands of people have been told to leave their homes in low-lying areas of Louisiana and Mississippi, though a mass evacuation has not been ordered. Storm warnings are also in place in parts of Florida, Texas and Alabama. The overtopped eight foot levee to the east of Plaquemines Parish is not part of the upgraded federal system protecting New Orleans after Hurricane Katrina.
Officials say Isaac is likely to weaken before it reaches New Orleans. Emergency management spokeswoman Caitlin Campbell says some people may be trapped in their homes in the parish by water from the overtopped levee.
"We don't expect a Katrina-like event, but remember there are things about a Category One storm that can kill you," said New Orleans Mayor Mitch Landrieu. Water levels in the area were reportedly five to nine feet, and there were several reports of people stranded in attics.
Of particular concern are storm surges, with peaks of up to 12ft (3.7m) forecast in parts of Mississippi and south-eastern Louisiana. Rainfalls of up to 1ft 8in are forecast across wide areas, along with a high chance of isolated tornadoes along the coast. Strong winds were hampering full-scale air and water rescue efforts in the area, but the New Orleans Times-Picayune reported that href="http://www.nola.com/hurricane/index.ssf/2012/08/hurricane_isaac_rescue_efforts.html" >local residents with boats had picked up about six people on the east bank of the parish. National Guard was also set to launch a rescue effort.
In New Orleans, the updated levees appeared to be holding as the city was lashed by rain and winds.
"We don't expect a Katrina-like event, but remember there are things about a Category One storm that can kill you," said New Orleans Mayor Mitch Landrieu on Tuesday.
