GULFPORT, Miss. — Hurricane Isaac came ashore Tuesday night west of the Mississippi River, arriving as a lumbering and large storm that threatened residents from Louisiana to the Florida Panhandle. Early reports from the storms landfall site sparked concerns of levee breaches.
Isaac made landfall as a Category 1 hurricane about 7:45 pm EDT and about 10 miles west of the mouth of the mighty Mississippi River and 90 miles southeast of New Orleans in Plaquemines Parish, La., packing winds in excess of 80 mph. The center of the hurricane was expected to skirt a wide stretch of Gulf of Mexico coastline, bringing havoc with it as it strengthened upon hitting shore.
Interviewed on The Weather Channel shortly after Isaac came ashore, Plaquemines Parish President Billy Nungesser said the storm surge had unexpectedly pushed up the Mississippi River, which has been at historical lows because of this summers punishing drought. Water was splashing over the tops of the rivers levees, causing concern.
Were concerned if this keeps up it will push up the river and bring the river over its banks, Nungesser said, noting his parish sticks out like a finger into the Gulf of Mexico.
However, U.S. Army Corps of Engineers spokesman Ken Holder told The Weather Channel that tidewaters were receding and no breach of levees was expected.
The National Hurricane Center reported Tuesday night a storm surge of 10.3 feet was registered at a National Ocean Service tide gauge in Shell Beach, La. A storm surge of 6.7 feet was reported at a tide gauge in Waveland, Miss. The center upgraded its rain forecasts at 10 p.m. central time, projecting seven to 14 inches in Louisiana, Mississippi and Alabama, warning of significant lowland flooding and 20 inches of rain in isolated locations.
This storm is packing a hell of a punch, said a worried Nungesser.
Power was out across parts of Louisiana, Mississippi and Alabama Tuesday night, with power company Entergy reporting more than 150,000 without power in the New Orleans area alone.
Reports of water over the Mississippi River levees was especially troubling as it came on the eve of the seventh anniversary of the day that Hurricane Katrinas second landfall devastated New Orleans on Aug. 29, 2005, and left more than 1,800 people dead in the city and along the Gulf Coast.
Worried about flooding and with Japans tsunami fresh in mind, the Nuclear Regulatory Commission said the Waterford 3 nuclear power plant in Killona, west of New Orleans, was shut down as a precaution
Isaac became a Category 1 hurricane shortly after noon EDT, with winds in excess of 75 mph, and never lost steam.
Hurricane Isaac is forecast to move inland as a Category 1 hurricane near the mouth of the Mississippi River late tonight, the National Weather Service said in an update from Shreveport, La. A flash flood threat is expected along with tropical storm force winds Wednesday through early Thursday morning.
Isaacs roughly 800-mile width meant it was expected to deliver a quadruple blow of storm surge, wind, rain and tornadoes over a large swath of the central United States. By Tuesday afternoon, the storms outer bands began coming ashore.
Were dealing with a big storm, and there could be significant flooding and other damage across a large area, President Barack Obama said Tuesday morning after receiving a briefing from Homeland Security Secretary Janet Napolitano and other federal officials. Now is not the time to tempt fate. Now is not the time to dismiss official warnings. You need to take this seriously.
Obama had issued a disaster declaration for the states of Louisiana and Mississippi, and Isaac will be the first large test of efforts to strengthen the levee system in the New Orleans area since Katrina swamped the hapless preparations in 2005.
Government response teams have fanned out across the Gulf Coast ahead of Isaacs arrival, said Craig Fugate, the chief of the Federal Emergency Management Agency.
Were really just urging people to heed any emergency measures, he said from Alabama during an afternoon conference call. He urged residents to stay inside and off the roads, so response teams dont have to go and fetch you.
By late Tuesday, shrimpers and fishermen along the coast either had moved their vessels up the Mississippi River to safer points of refuge or had simply abandoned them to the fates. In the Mississippi Sound, in Pass Christian, Miss., Mayor Chip McDermott struggled to tie off a 60-foot shrimp boat that its owner had left in the harbor. Water crept toward the sea wall before noon. A huge trash bin bobbed inside the harbor.
McDermott expected 10 feet to 12 feet of storm surge in Pass Christian, where 70 percent of residents live in flood zones.
Were fixing to have water, McDermott said. Aint no way around this.
Coastal residents gathered supplies in an orderly fashion Tuesday and did what they needed to do to get ready for Isaac.
When you live through storms, said Mark Kirsch, a former Coast Guard meteorologist who lives on the Mississippi coast, it brings your level of preparedness up. . . . We know what they can do.
Just where Isaac will come ashore remained uncertain, said Richard Knapp, the head of the National Hurricane Center.
Its not a point on the map; its a huge storm, Knapp said from Miami in a conference call, discouraging too much attention on where the storms center hits land.
Much of Louisiana, Mississippi and Alabama will be soaked, he predicted.
I dont want folks to take this lightly just because its not a major hurricane, he said, noting that the categories of storms measure wind speeds and that Isaacs threat comes from its size and its slow movement, at 10 mph. That category does not capture the fact that this is a large system and a slow-moving one. . . . The large size plus the slow motion, it means near the coast and well inland the rainfall and flooding could be a serious issue.
Mississippi was hard-hit by Katrina, and residents along its coastline braced Tuesday for the worst from Isaac.
In Harrison County, home to the resort cities of Biloxi and Gulfport, a curfew was imposed from 7 p.m. Tuesday until 7 a.m. Wednesday.
We dont want to deal with traffic while were dealing with other issues, Sheriff Melvin Brisolara said, predicting many impassable roads. The curfew, he said, is mainly for public safety issues.
Coastal Mississippi felt the effects of Isaac at high tide Tuesday morning. There was seawater on U.S. 90, a four-lane highway that runs along the beach area. The highway was ordered closed by nightfall.
"This is not rainwater were looking at," said Rupert Lacy, the countys emergency manager. This is water coming off the gulf. Thats a little alarming.
Residents in low-lying coastal areas were put under mandatory evacuation around midday, and the county opened four shelters, each capable of housing more than 200 people, with plans to open two more late Tuesday.
By midday Tuesday Isaacs presence was felt in the New Orleans area, too.
We just got the first rain bands . . . COLD rain, Lisa Yanes, a resident of Harvey, La., a community just southwest of New Orleans, wrote in a Facebook message to McClatchy.
Bars were open at least half of Tuesday, Yanes said of an area thats best-known for its alcohol-fueled fun. By late afternoon, power was out in Harvey and much of the New Orleans area. The local newspaper, The Times-Picayune, reported that flooding already had closed portions of U.S. 90 in east New Orleans and residents were scrambling for alternative routes westward.
Residents of unincorporated Harvey, near the Intracoastal Waterway, werent forced to evacuate. But less than 10 miles away, residents were ordered to leave Belle Chasse, part of Plaquemines Parish, hard hit by Katrina.
In Jefferson Parish, Sheriff Newell Normand urged residents to stay put.
You need to stay home. If youre bored, dont get in your truck and drive the neighborhoods. Play Parcheesi; do something else, but dont go out on the streets, he said during a news conference late Monday.
Coast Guard crews in Pensacola, Fla., were looking Tuesday for a missing Jet Skier whod failed to return home Monday night. The 47-year-old man apparently had ignored warnings about deteriorating weather conditions along the Gulf Coast.
The Port of New Orleans was closed Tuesday, as was the Port of Mobile in Alabama. Barge traffic along the Mississippi River was halted from Baton Rouge, La., south to the mouth of the mighty river.
Any movement on the waterways is only by permission of the captain of the port; everything is shut down, said Petty Officer 2nd Class Elizabeth Bordelon, a Coast Guard spokeswoman in New Orleans whose office looks out at the river. Its strange to see no traffic. The streets are pretty quiet here.
While Gulf Coast residents will feel Isaacs wrath, much of the East Coast is likely to feel the storm in the wallet. Almost 94 percent of oil production in the waters of the Gulf of Mexico was shut in by Isaac, the Energy Department said Tuesday afternoon. Gasoline refineries in the New Orleans area, with a capacity to refine 3 million barrels a day, ramped down production.
If theres significant flooding or wind damage, it could crimp gasoline production and gasoline shipments via pipeline to hub cities such as Atlanta, which serve the Eastern Seaboard. Isaac could raise gasoline prices above $4 a gallon temporarily on parts of the East Coast.
Gasoline prices leapt to a nationwide average of $3.756 a gallon Tuesday, the highest since early May, on concerns about supply disruptions.
White House Press Secretary Jay Carney said that all options remain on the table when he was asked about releasing oil from the Strategic Petroleum Reserve if gasoline prices stay high after Isaacs romp.
