Hurricane Barry is barreling northwest toward Louisiana, packing maximum sustained winds of 75 miles per hour (120 km/h), with heavy rain, storm surges and risky winds expected along the northwest Gulf Coast.
Because of the storm's slow movement, rain won't taper off in Louisiana and MS until the second half of Monday or Monday night from south to north. Rain could linger in Arkansas and western Tennessee through Tuesday, where 6 to 10 inches of rain could fall and trigger flooding.
The center of Barry will move across the western and northern portions of Louisiana on Sunday and over Arkansas on Sunday night and Monday, the NHC said. The U.S. National Hurricane Center said Sunday parts of south-central Louisiana could still have rainfall totals of up to 12 inches, with isolated pockets of 15 inches.
What is left of Barry will track up into Missouri by late Monday.
In addition, very serious river flooding is still expected in parts of Louisiana.
In Mississippi, up to 3 inches (7.6 centimeters) of rain had already fallen in the Jackson area before dawn Sunday - and more was on the way.
This is the first time all floodgates have been closed in the New Orleans-area under the Hurricane Risk Reduction System since Katrina, according to Governor John Bel Edwards. The temperature is forecast to drop to about 67 degrees Sunday night with mostly clear skies.
The city's emergency preparedness campaign has urged residents to remain vigilant and stay patient. The Trump administration has said it might reconsider that decision.
At least 153,547 customers in Louisiana were without power as of the early hours of Sunday. "Please be very careful!" Due to the Hurricane Emergency Center declaring that the storm was "strengthening" and that "water is going to be a big issue", the governors of Louisiana and MS have declared a state of emergency.
The storm made landfall as a Category 1 hurricane at Intercostal City, Louisiana on Saturday. The surge topped two levees in southeast Louisiana. Police have gone door-to-door asking residents to evacuate.
Barry was downsized from a Hurricane Sunday evening yet kept on representing a danger.
The corridor of tropical rain will continue to cause tornadoes, local flash floods in Louisiana and MS.
"There have been NO levee failures in Plaquemines Parish".
An evacuation order was also issued for all areas along both Brady Road and Highway 315 on Saturday afternoon.
The United States Coast Guard had to conduct several water rescues in Terrebonne Parish. The remnants of Barry will gain speed as it moves through the region.
The rain is light enough and the system moving fast enough that flash flooding is not a major concern at this time.
In St. Mary Parish, about 60 miles east of where Barry made landfall, 64-year-old Joyce Webber and about 20 others huddled inside the Baldwin Community Center to take refuge from the storm.
Here, the gate of the US Customs House in New Orleans is seen sandbagged in the hope of stemming the surge. Residents were told to shelter in place by 8 p.m. CDT Friday. The Mississippi River, which flows through the city, is forecast to rise to as high as 5.2 meters (17.1 feet) on Saturday - the highest level since 1950, and close to the top of the city's levees.
Every flood gate has been closed along Lake Pontchartrain due to the anticipated flooding.
This street in New Orleans' Garden District suffered flooding days before the actual storm arrived.
