NEW ORLEANS (AP) — Tropical Storm Karen stalled Saturday afternoon in its move toward the Gulf Coast but still threatened to bring heavy winds and high rains. Officials from Louisiana to northwest Florida acknowledged that the storm was weakening and sent some emergency workers home, but urged residents to be cautious.
"The storm's weakened, and that's good news, but we're not out of the woods yet," New Orleans Mayor Mitch Landrieu said at a news conference. He warned of likely high winds, street flooding and power outages.
The National Hurricane Center in Miami said Saturday afternoon that Karen hadn't moved for a few hours. It had maximum sustained winds of 40 mph, making it a weak tropical storm. Forecasters expect it to resume its northerly track and be near or over portions of southeastern Louisiana on Saturday night and Sunday. It could speed up into Sunday and is likely to pass near the coasts of Mississippi and Alabama that day.
Rick Knabb, the director of the National Hurricane Center in Miami, noted that "there is still the potential for some locally heavy rainfall and for some storm surge in coastal areas, but the magnitudes of those hazards greatly reduced. We still could see 1 to 3 feet of coastal flooding due to storm surge in some spots."
In low-lying Plaquemines Parish, La., officials changed an evacuation order from mandatory to voluntary Saturday afternoon. More than 80 evacuees from the area, at the state's southeastern tip, had taken refuge at a public shelter, which would remain open Saturday.
They gathered in an auditorium where they rested on cots, watched for weather updates on TV and chatted outside on the front steps.
"I don't really know what to expect, but they told us to evacuate, so we got out," said Dana Etienne, 27, of Phoenix, La., who was at the shelter with her three young children.
Coastal authorities closed flood gates along waterways that could be affected by tides driven by the storm. In New Orleans, the U.S. Army Corps of Engineers continued closing barriers designed to keep surge out of the Inner Harbor Navigation Canal — scene of catastrophic flooding in 2005 when flood walls failed during Hurricane Katrina.
Col. Richard Hansen of the corps said more gates along various canals could be closed, and warned boaters not to get caught on the wrong side of those gates "If there is a gate in the system, it may not be open when you decide to come back in," Hansen said. "So it's time to pull your boats out of the water and quit fishing."
Dan Hahn, emergency operations planner for Santa Rosa County in the Florida Panhandle said Karen appeared to be a "nonevent" for the region.
The county had activated its Emergency Operations Center for the weekend, but decided to close on Sunday after getting the latest update on the storm's path. Hahn said he and other officials were relieved the storm wasn't more developed. But Hahn still urged residents to pay attention to weather updates and to be prepared for a any emergency.
"Complacency is always a concern, but we aren't seeing that," he said, adding that most Panhandle residents take tropical weather seriously because of the large storms that have struck the region in the past.
Mississippi Emergency Management Agency spokesman Brett Carr said the Mississippi National Guard was demobilized Saturday after coastal county officials said they "didn't see the need to keep them around."
In Mississippi and elsewhere, some people couldn't resist the draw of beaches.
Ray and Lynn Walls of Shepherdsville, Ky., had a sunny beach to themselves Saturday on the western tip of Dauphin Island, Ala. Big waves pounded the seawall protecting nearby homes, and a locked gate blocked the entrance to a public beach that was closed because of Karen.
The trip had been planned for four people, but only two showed up, Ray Walls said. "The rest of them got a little scared of the storm."
In Biloxi, Miss., families played on the beach, joggers trotted along the waterfront and a steady stream of cars passed on the main beach front road. Resident Tracey Bardong said nobody had canceled reservations at any of her four rental properties.
Karen's weakening meant possible disappointment for Cheryl Greer, who drove through the night from Nicholasville, Ky., on a weekend adventure to Mississippi to visit her daughter and experience her first tropical storm.
"I'm looking forward to it. It would be my first one," she said. "I'm going to come to the beach and video it."
Thu Bui and her two young sons were in Pensacola Beach, Fla., on vacation, spending Saturday morning fishing from the beach pier. Bui said the kids were disappointed that they weren't allowed in the water because of the rough surf.
As of Saturday afternoon, Karen was about 130 miles (205 kilometers) south-southwest of Morgan City, La., and about 190 miles (305 kilometers) west-southwest of the mouth of the Mississippi River.
A tropical storm warning remains in effect from Morgan City to the mouth of the Pearl River. A tropical storm watch covers the New Orleans area and a stretch from east of the Pearl River's mouth to Indian Pass, Fla.
