Heavy rains have already brought flash flooding to the city
A slow-moving storm is forming into a likely hurricane in the Gulf of Mexico, and is forecast to hit the already-flooded US city of New Orleans.The storm, which is currently classified as a tropical storm, has already brought thunderstorms to the city, triggering flash floods.A state of emergency is in effect and residents in some low-lying areas have been asked to evacuate.The river may come dangerously close to overtopping levees shielding the city.The Mississippi River may rise as high as 20ft (6m) above sea level, officials warn, potentially exceeding the 20-25ft levees protecting New Orleans.
"We're confident the levees themselves are in good shape. The big focus is height," Ricky Boyett, a spokesman for the US Army Corps of Engineers, which maintains the fortifications, told the AP.

Storm surges are expected to see rivers and tides crest at levels far higher than average, officials warn.The primary danger is in the amount of water from surges and rainfall, according to emergency responders, rather than wind damage.Tropical Storm Barry is currently "moving very slowly to the west at 5mph" the National Weather Center warned in an advisory on Thursday.The National Hurricane Center warns that the storm may produce tornados along southern portions of Louisiana and Mississippi.

Officials warn that even if the storm does not form into a hurricane, heavy rain could still create dangerous conditions lasting for days."No one should take this storm lightly," said Governor John Bel Edwards as he declared a state of emergency."As we know all too well in Louisiana, low intensity does not necessarily mean low impact."
