Weakened Barry drenches Louisiana, millions brace for flooding

Weakened Barry drenches Louisiana, millions brace for flooding

It will become a hurricane once winds reach 74 miles per hour, and Barry could potentially come ashore as a Category 1 storm, the weakest on the five-step Saffir-Simpson scale, according to the NHC.

New Orleans is particularly vulnerable to flooding because of its low elevation.

New Orleans was already saturated after thunderstorms drenched the city with a foot of rain on Wednesday.

Mandatory evacuation orders were issued across the region in low-lying areas and those outside public levee protection, according to the governor's office, while some areas had voluntary evacuation warnings.

The city's Sewerage and Water Board, which operates the pumps created to purge streets and storm drains of excess water, was expecting between 6 and 12 inches of rain, down from up to 20 inches or more in some earlier forecasts. Barry probably won't be remembered for its winds.

"There are going to be short-term effects on the ecosystem", Muth said. Over the past seven decades tropical events like Barry have slowed down, going 20-30% less quickly over land in North America.

As Barry has moved inland, maximum sustained winds have dropped to 60 miles per hour (85 kph), with an estimated minimum central pressure is 998 mb (29.47 inches), according to the NHC 7 p.m. update.

The National Weather Service (NWS) earlier warned the Mississippi River could crest at 19ft or 20ft during the storm, but on Friday revised their estimate down to 17ft. That should keep the river below the tops of levees in the city, according to Cantrell. "So the flooding threat is not over, especially across central Louisiana".

The Coast Guard rescued a dozen people from flooded areas of Terrebonne Parish, south of New Orleans, some of them from rooftops, a spokeswoman said. "Stock up food. Get ready for the storm - ride it out", he said.

"Flash flooding and river flooding will become increasingly likely, some of which may be life-threatening, especially across portions of southeast Louisiana into MS", forecasters said. The surge topped two levees in southeast Louisiana. For several days, officials braced for more flooding.

Opposition leader in the National Assembly and PML-N president Shahbaz Sharif also called for the immediate release of his elder brother.

US crude futures CLc1 settled up a penny at $60.21 a barrel and natural gas futures NGc1 rose 1.7% despite an International Energy Agency report on Friday that projected a growing global surplus of oil.

Almost 70% of crude oil production and 56% of natural gas output in the USA -regulated areas of the Gulf of Mexico has been cut because of the storm, the Bureau of Safety and Environmental Enforcement said. About 1.35 billion cubic feet a day of natural gas production is also halted.

He was keeping a close eye on the nearby Mississippi River.

The storm is putting 70 per cent of newly minted U.S. LNG capacity at risk, with Cheniere Energy Inc.'s Sabine Pass export terminal and Sempra Energy's Cameron facility potentially in its path.

Here are some wind reports from earlier this afternoon in Louisiana.

Barry is expected to produce total rain accumulations of 10 to 20 inches over south-central and southeast Louisiana and southwest MS, with isolated maximum amounts of 25 inches. Royal Dutch Shell Plc's Norco and Convent refineries are said to be reducing rates on some units and sending nonessential workers home.

On-again, off again rain hit New Orleans overnight. At least 13 oil ships were waiting in the Gulf of Mexico Thursday, bound for ports that could be affected by the storm. "Power outages will be significant, in fact they're already significant in some areas of the state".

Yet even if this year's oxygen-depleted area winds up smaller than expected, historical data suggests that Barry - like other big storms - will flush additional nutrients into the MS and other Gulf tributaries, leading to bigger dead zones in the long run, said Anna Michalak of the Carnegie Institution for Science in Stanford, California.

Officials in Lafourche Parish also posted a recommended evacuation notice for parts of the parish, due to overtopping of the levee system in Point Aux Chenes.
