NEW ORLEANS (AP) — Hurricane Nate came ashore at the mouth of the Mississippi River on Saturday and pelted the central Gulf Coast with wind and rain as the fast-moving storm steamed toward the Mississippi coast, where it was expected to make another landfall and threatened to inundate homes and businesses in vulnerable low-lying areas.
Nate was expected to pass to the east of New Orleans, sparing the city its most ferocious winds and storm surge. And its quick speed decreased the likelihood of prolonged rain that would tax the city's weakened drainage pump system. Still, the city famous for all-night partying was placed under a curfew, effective at 7 p.m., and the streets were not nearly as crowded as they would be on a typical Saturday night.
Cities along the Mississippi coast such as Gulfport and Biloxi were on high alert. Some beachfront hotels and casinos were evacuated. Rain began falling on the region Saturday and forecasters called for 3 to 6 inches (7 to 15 centimeters) with as much as 10 inches (25 centimeters) in some isolated places.
Nate weakened slightly and was a Category 1 storm with maximum winds of 85 mph (137 kph) when it made landfall. Forecasters had said it was possible that it could strengthen to a Category 2, but that seemed less likely as the night wore on.
Storm surge threatened low-lying communities in southeast Louisiana, eastward to the Alabama fishing village of Bayou la Batre.
"If it floods again, this will be it. I can't live on promises," said Larry Bertron as said as he and his wife prepared to leave their home in the Braithwaite community of vulnerable Plaquemines Parish. The hurricane veterans lost one home to Hurricane Katrina in 2005 and were leaving the home they rebuilt after Hurricane Isaac in 2012.
Governors in Louisiana, Mississippi and Alabama declared states of emergency. The three states have been mostly spared during this hectic hurricane season.
"This is the worst hurricane that has impacted Mississippi since Hurricane Katrina," Mississippi Emergency Management Director Lee Smithson said Saturday. "Everyone needs to understand that, that this is a significantly dangerous situation."
Louisiana Gov. John Bel Edwards urged residents to make final preparations quickly and stressed that Nate will bring the possibility of storm surge reaching up to 11 feet in some coastal areas.
"It's going to hit and move through our area at a relatively fast rate, limiting the amount of time it's going to drop rain," Edwards said. "But this is a very dangerous storm nonetheless."
Streets in low-lying areas of Louisiana were already flooded. Places outside of levee protections were under mandatory evacuation orders and shelters opened there.
Some people worried about New Orleans' pumping system, which had problems during a heavy thunderstorm on Aug. 5. The deluge exposed system weaknesses - including the failure of some pumps and power-generating turbines - and caused homes and businesses to flood. Repairs have been made but the system remained below maximum pumping capacity.
On Alabama's Dauphin Island, water washed over the road Saturday on the island's low-lying west end, said Mayor Jeff Collier. The storm was projected to bring storm surges from seven to 11 feet near the Alabama-Mississippi state line. Some of the biggest impacts could be at the top of funnel-shaped Mobile Bay.
The window for preparing "is quickly closing," Alabama Emergency Management Agency Director Brian Hastings said.
Florida Gov. Rick Scott warned residents of the Panhandle to prepare for Nate's impact.
"Hurricane Nate is expected to bring life-threatening storm surges, strong winds and tornados that could reach across the Panhandle," Scott said. The evacuations affect roughly 100,000 residents in the western Panhandle.
The Pensacola International Airport announced it will close at 6 p.m. Saturday and remain closed on Sunday. However, the Louis Armstrong New Orleans International Airport was open Saturday.
"We are urging customers to check with their specific airlines to see whether their flights have been canceled because there have been some of those," spokeswoman Michelle Wilcut said.
At 8 p.m. EDT Saturday, Nate was about 10 miles (16 kilometers) southwest of the mouth of the Mississippi River. The storm is expected to quickly weaken as it cuts a path through the Southeast on its way to the Northeast, which could see impacts from Nate early next week.
Nate killed at least 21 people after strafing Central America.
Waterside sections of New Orleans, outside the city's levee system, were under an evacuation order. About 2,000 people were affected. But not everyone was complying.
Gabriel Black stayed behind because an 81-year-old neighbor refused to leave.
"I know it sounds insane, but he has bad legs and he doesn't have anybody who can get to him," Black said.
Ahead of Saturday night's curfew, some bars were closed in the French Quarter but music blasted from others.
