NEW ORLEANS, La. — Barry made landfall as a Category 1 hurricane early Saturday afternoon along Louisiana's central coast, then immediately weakened back into a tropical storm, according to the National Hurricane Center.
The center of the storm -- the first hurricane to hit the US this year -- was about 5 miles northeast of Intracoastal City and about 30 miles south-southwest of Lafayette at 2 p.m. ET and still crawling at 6 mph, with maximum sustained winds of 70 mph.
Rainfall now poses the greatest threat. Barry's slow trek means residents from the Gulf Coast through the lower Mississippi Valley will see extended heavy downfalls that could prompt flooding that lasts into next week, forecasters said.
Dangerous coastal storm surge had overtopped levees by midday Saturday along the far reaches of Louisiana's coast, local officials reported. Tornadoes also posed a risk from southeast Louisiana to south Alabama.
Ludovico Torri woke Saturday to find Lake Pontchartrain lapping at his home in Mandeville, Louisiana, north of New Orleans.
"When we woke up this morning, the entire street and area under the house was under water," he told CNN. "The waves from the lake are crashing onto the land as if it is all one big lake."
"We're stuck in the house with four kids, and the car is almost flooding," Torri said, noting that within an hour and a half, the water had risen a foot. "The wind's getting stronger, and the water is rising and rising."
Though heavy, sustained rain still threatens the New Orleans area, fears among residents and forecasters there relaxed as a predicted storm surge on the unusually high Mississippi River happened late Friday at a lower level than anticipated, according to the National Weather Service in New Orleans.
The developing factors had called to mind for some the death and destruction wrought in 2005 by Hurricane Katrina, though the weather and flood-infrastructure circumstances are not the same.
A hurricane warning is in effect along part of the Louisiana coast, while inland areas, including the lower Mississippi Valley, are under tropical storm warnings. Storm surge warnings along the coast extend from Intracoastal City, south of Lafayette, to Biloxi, Mississippi, and along Lake Pontchartrain.
Tropical-storm-force winds will extend up to 175 miles outward from the storm's center.
More than 77,000 customers across Louisiana were without power on Saturday morning, utility providers said. Hundreds of flights in New Orleans were canceled, and some cruise ship departures were in flux.
The real danger is the rain
Top of mind as Barry nears land is the heavy rains and related flooding it's expected to usher in.
"We are talking about 18-24 hours after landfall, the rain will still be coming down and will be the issue," CNN Meteorologist Michael Guy said.
Gov. John Bel Edwards said some areas could see up to 25 inches of rain.
"Nobody should take this storm lightly just because it's supposed to be a Category 1 (hurricane) when it makes landfall," the governor said. "The real danger in this storm was never about the wind anyway, it's always been about the rain, and that remains a very significant threat."
When the ground is as saturated as it already is in the region, the governor said, the risks are endless. "It doesn't take much wind to cause a tree to fall or a utility pole to fall," he said. "These hazards are going to present themselves all over the state."
Residents assured pumps are working and capable
Officials had warily eyed the Mississippi River earlier this week, when forecasts showed a potential storm surge of 2 to 3 feet could push the waterway's height to about 19 feet in New Orleans, frighteningly close to the top of levees that protect up to 20 feet.
But those fears have calmed since late Friday, when the surge crest only pushed the river to 16.9 feet. The risk of overtopping was minimal, per the New Orleans Office of Homeland Security and Emergency Preparedness said.
Barry's heavy rain is predicted to push the river level up again on Monday, but only to 17.1 feet, forecasters said, and Kevin Lykins, a resident of Magazine Street, mere blocks from the river, wasn't concerned about the Mighty Mississippi at all.
"We are just hoping the pumps work," he said, referring to the citywide system of massive pumps, canals and underground pipes that move water off streets and into nearby waterways. "We really aren't worried about the (river) levees over here. We are more worried about the rain and flooding and hoping our city officials have our pumps ready to go."
Residents were reassured Saturday that the city's pumps are working, even if it looks like floodwater is standing still.
"It takes a long, long time for the water to recede," Sewerage and Water Board Executive Director Ghassan Korban said, comparing the city to a full bathtub and its drainage pump system to the plug. It takes a while for the water to go down once the plug has been pulled, he said, but it's working.
In Morgan City, where the hurricane is expected to make landfall, officials and city workers were also worried about lingering water. The fishing and oil hub is about 70 miles southwest of New Orleans and south of Lafayette.
With up to 30 inches of rain projected this weekend for the region, Mayor Frank "Boo" Grizzaffi worried it may be more than the city's drainage system can take, so the city contacted the state and got additional pumps to help tackle the deluge.
"Our city can handle the first 5 inches comfortably," he told CNN, standing along the seawall Saturday morning. "After that, 1 inch every additional hour. So, when you've got a forecast of 30 inches, the math doesn't work."
But Grizzaffi was confident the city could handle whatever Barry throws its way.
"There's a lot of rain coming. Someone's going to get it," he said. "We're prepared for it if it comes this way."
Evacuations ordered and National Guard called up
Across the region, cities and parishes have issued mandatory evacuation orders, especially in low-lying areas and those outside public levee protection, along with voluntary evacuation warnings for other places, the governor said. For the first time since their construction, all major floodgates on the Mississippi River are closed, he added.
The state's forces also have mobilized in anticipation of search and rescue missions, he said.
A rescue already was underway midmorning Saturday -- and more calls for help had come in -- in coastal Terrebonne Parish, east of Morgan City, the US Coast Guard said. At least a dozen people needed to be saved along Island Road, effectively a bridge that traverses the marshy bayou that opens into the gulf.
Four people and a cat were picked up by a MH-65 Dolphin helicopter and taken inland to Houma, Louisiana, Coast Guard Petty Officer Lexie Preston said. The other eight were also safely ferried to Houma, a Terrebonne Parish spokesman said.
A 24-foot Coast Guard response boat was launched from Morgan City to help with rescues.
Following President Donald Trump's state of emergency declaration, Louisiana officials activated 3,000 National Guard members in anticipation of Barry, the governor said. And despite the state's long-honed expertise in facing this sort of threat and its enhanced post-Katrina storm defenses, residents were urged to be prepared.
Canceled flights, cruises and a concert
More than 250 flights were canceled as of Saturday morning in and out of Louis Armstrong New Orleans International Airport, according to flight-tracking website FlightAware.
Three Carnival Cruise Line ship departures scheduled for Saturday, Sunday and Monday are in limbo following the closure of ports in New Orleans and Mobile, Alabama. The cruise line said it will update passengers Saturday morning.
Meantime, the Rolling Stones postponed a Saturday concert to Monday.
"Hang on to your tickets," the legendary band tweeted. "We're here with you -- we'll get through this together."
Storm triggers latent Katrina fears
For some in New Orleans, Barry -- on the heels of a swift, strong rainstorm Wednesday that flooded some homes and businesses -- brought to mind Katrina, when the failure of federal levees let Lake Pontchartrain and other adjacent waterways spill into the city while at the same time rendering the municipal drainage system useless to pump that water out.
Tanya Gulliver-Garcia, who lives in the city's Broadmoor neighborhood, flew out ahead of Barry, leaving behind neighbors with vivid memories of the 2005 destruction, she said.
"This storm is stressing them out," Gulliver-Garcia told CNN. "Trauma stays in your body, and Katrina left a lot of trauma behind."
Lykins' home was "completely destroyed" by Katrina, he said.
"But we rebuilt because we love it down here with our culture," he said "New Orleans is just home to us."
Most New Orleanians, though, opted to stay put. Herman Grady evacuated during Katrina, but this time, he's staying back.
"I'm tired of running," the 72-year-old told CNN affiliate WDSU.
Many residents aren't eager to endure the expense and effort of leaving, compared with what could be a few uncomfortable hours or days without power or other amenities. Many also want to stay home so they can bail water if it rises, then dry out floors and drywall as soon as it recedes so mold doesn't take root and worsen damage.
