New Orleans holds up under Tropical Storm Lee

NEW ORLEANS (Reuters) - Tropical Storm Lee, packing heavy rains, edged across southern Louisiana on Sunday as New Orleans' flood defenses appeared to pass one of their biggest tests since Hurricane Katrina devastated the city in 2005.
The National Hurricane Center said Lee's center was about 120 miles northwest of New Orleans, with maximum sustained winds of 40 mph around 8 p.m. EDT, and tropical storm-force winds extending 275 miles. The storm was moving at 6 mph.
The storm has temporarily shut over 60 percent of offshore oil production.
Lee is expected to bring soaking rains and flooding to Mississippi on Monday, and to Alabama, Tennessee and Kentucky on Wednesday and Thursday, the hurricane center said.
The storm will remain a rainmaker even after it weakens to a tropical depression, carrying the potential for to 10 inches of rain, flash flooding and tornadoes as it moves northeast, forecasters said.
In New Orleans, the storm recalled Hurricane Katrina, which flooded 80 percent of the city, killed 1,500 people and caused more than $80 billion in damage to the tourist destination. Lee has dropped up to 13 inches of rain on New Orleans since it developed late last week.
Half the city lies below sea level and is protected by a system of levees and flood gates.
Some street flooding was reported, but the city's massive pumping system kept ahead of the volume and diverted the waters into Lake Pontchartrain.
Low-lying parishes around New Orleans did not fare as well, as Lee's winds drove a tidal surge over levees and onto roads.
"For a while we got some false hope that we might be out of the woods, but we realized overnight we would get more rain," Lafourche Parish spokesman Brennan Matherne said. "We're getting call after call about street flooding."
New Orleans Mayor Mitch Landrieu warned residents to stay alert for flash floods and high winds expected before Lee departs.
"Let's not be lulled to sleep by the breaks that we've had," Landrieu said.
New Orleans' levees saw less stress because Lee's winds were too weak to drive a massive storm surge into the city, as was the case during Katrina.
"The levees at this point are really not being tested because the surge is not coming into the system," said Colonel Edward Fleming of the U.S. Army Corps of Engineers. "This is mainly a wind and a rain event."
There were isolated reports of flooding in roads and homes. No injuries or deaths were reported in Louisiana.
Wet conditions associated with the storm appeared to be a factor in an early morning car wreck in Mobile, Alabama, that killed one man and left several injured.
Lee's tidal surge could spur more coastal flooding in Louisiana, as well as in Mississippi and Alabama, before drenching a large swath of the Southeast and Appalachian regions in the coming days.
Storm winds have already pushed Gulf waters inland, slamming barriers in low-lying areas such as Lafourche Parish and prompting mandatory evacuations in the coastal communities of Lafitte, Crown Point and Barataria.
In Mississippi, local governments were taking precautions as forecasters predicted tides could be 2 feet to 4 feet above normal.
As of Sunday afternoon, 6,149 customers were without power in Louisiana and 609 in Mississippi, utility Entergy Corp reported.
More than 60 percent of U.S. offshore oil production, all based in the Gulf of Mexico, and over 44 percent of offshore gas production were shut as of Saturday, according to the U.S. government. Most of that output should quickly return once the storm passes.
Major offshore producers like Royal Dutch Shell, Exxon Mobil Corp and BP Plc shut down platforms and evacuated staff late last week.
Shell, Exxon and Anadarko Petroleum Corp have started to return workers to offshore platforms.
Low-lying refineries in Louisiana that collectively account for 12 percent of U.S. refining capacity were watching the storm closely, but reported no disruptions.
In the open Atlantic on Sunday, Hurricane Katia strengthened rapidly to a Category 2 storm.
