May 2 (Bloomberg) -- U.S. President Barack Obama will arrive on the Gulf Coast today to review efforts to stem an oil- well leak with a flow rate that’s “impossible” to estimate, according to the U.S. Coast Guard.

Some of the oil has reached land in Louisiana, and “the more significant oil is coming” within two days, Governor Bobby Jindal said at a news conference yesterday. More than 2,000 people have been deployed to protect the shoreline and coastal wildlife, according to a statement from the multiagency Joint Information Center coordinating the federal response.

BP Plc, the owner of the offshore well, is seeking ways to plug the leaks that are spewing crude 5,000 feet under the water’s surface. The company has started drilling a second well to take pressure off of the current gusher. The U.S. Coast Guard said it has been unable to get an accurate estimate of how much oil is leaking and is preparing for a worst-case scenario.

The oil spill followed an April 20 explosion on a drilling rig leased by BP. The rig, owned by Transocean Ltd., sank two days later. Obama has ordered that no new offshore drilling leases be issued until a “thorough review” of the incident is completed.

Flow Estimation Impossible

“Any exact estimation of what’s flowing out of those pipes right now is almost impossible because of the depth of the water,” said Admiral Thad Allen in a conference call with reporters yesterday. Allen, the U.S. Coast Guard commandant, was designated the national incident commander to coordinate efforts to control the oil spill and minimize the damage.

“The focus has to be to stop it at the source,” Allen said.

Obama is scheduled to make a statement at 2:30 p.m. local time today from Venice, Louisiana, after a briefing with response officials there.

BP’s so-called relief well is due to be completed in about 90 days, Michael Abendhoff, a company spokesman, said today in a phone interview from Robert, Louisiana.

While the London-based company has continued to spread chemicals under water close to the source of the leak, it hasn’t been able to fully assess the efficiency of the method, Abendhoff said. BP has released 156,012 gallons of dispersant so far to break up the oil, said Bill Salvin, another BP spokesman.

Strong winds and 7-to-10-foot waves make it impossible to measure whether the dispersants lowered the volume of oil emerging on the sea surface, Abendhoff said.

Flyovers Today

The response teams are able to do flyovers today after stormy weather yesterday, and forecasts call for improved weather for the next four to five days starting tomorrow at the earliest, Salvin said.

Surface estimates of the size of the slick and skimming efforts were hindered as the Coast Guard ordered boats and aircraft back to port because of stormy weather. Salvin said 23,968 barrels of crude and other material has been picked up by skimming boats.

The National Oceanic and Atmospheric Administration previously estimated the well is spewing 5,000 barrels of oil a day. At that rate, the volume of the spill would exceed Alaska’s 1989 Exxon Valdez accident by the third week of June.

BP Chief Executive Officer Tony Hayward arrived in the Gulf area late last night to oversee efforts to combat the leak and will stay several days.

Production Halted

About 6.2 million cubic feet of gas production was halted yesterday as environmental and safety concerns stopped operations at two offshore platforms and prompted one to be evacuated. That’s less than a 10th of 1 percent of U.S. output.

“This is an American Chernobyl,” said Louie Miller, 55, senior representative for the Sierra Club in Mississippi, referring to the explosion at a Ukrainian nuclear reactor in 1986 that killed 56 people, destroyed wildlife and contaminated waterways. Oil “may not be radioactive, but it’s toxic.”

The Louisiana Department of Health and Hospitals advised residents not to swim or fish in affected waters and to prevent young children, pregnant women and pets from entering contaminated areas.

The impact on wildlife “depends on the tides, weather and other factors beyond our control,” Jay Holcomb, director of The International Bird Rescue Research Center, said in a statement. The organization has set up bird-rescue centers in Louisiana and Alabama.

Fishing Unaffected

Commercial shipping on Mississippi River fairways hasn’t been significantly affected so far, though that may change if cleanup efforts are implemented, Allen said. Traffic may be halted in contaminated areas or ships will have to be washed after passing through oily waters.

St. Bernard Parish in Louisiana will employ local fishermen to deploy protective booms after training them on the procedure yesterday morning, the parish said in a statement.
Defense Secretary Robert Gates approved a request by Jindal to mobilize as many as 6,000 National Guard troops to add security, medical support, engineers, communications capability and cleanup crews to the oil slick containment effort, spokesman Geoff Morrell said late April 30.

A T-shirt vendor saw something suspicious in New York's Times Square Saturday evening -- smoke coming from an unoccupied SUV on 45th Street near 7th Avenue -- so he alerted police.
Authorities found potentially deadly explosives in SUV left in Times Square.

The tip led to what New York Mayor Michael Bloomberg called an "amateurish"-looking car bomb and what Secretary of Homeland Security Janet Napolitano told ABC News' "This Week" today might have been part of a "one-off" attack.

The 6:30 p.m. scare prompted police to evacuate thousands of people from the heart of the Big Apple during one of its busiest times -- a warm Saturday night when it was packed with theatergoers and tourists.

"We are very lucky," Bloomberg said. "Thanks to alert New Yorkers and professional police officers, we avoided what could [have been] a very deadly event."
Authorities were examining security cameras and other evidence to see if they could identify a possible suspect or motive -- and already had located video of the car being driven to the scene.

"Tape is being reviewed and additional forensics are being done in addition to that," Napolitano said. "Times Square, I think, now is safe."

President Obama was being kept informed on the investigation by Deputy National Security Advisor John Brennan, who was communicating with the New York Police Department and other investigators, the White House announced Saturday evening.

How's this for consistency: Freddy Krueger has hit the No. 1 spot at the box office for four straight decades.

He did it again this weekend, as the "re-imagining" of A Nightmare on Elm Streetscared up $32.2 million, according to studio estimates.

The horror film, starring Jackie Earle Haley as the dream-trolling demon, met most analysts' expectations and concluded a robust spring for the industry, which saw attendance up 4% over spring 2009.

As usual with Nightmare, critics weren't kind to the film; 15% of reviewers recommended the movie, according to RottenTomatoes.com. But audiences didn't care, giving the movie — the ninth installment since the franchise began in 1984 — the second-highest debut in the franchise's run, second only to Freddy Vs. Jason, which opened to $36 million in 2003.

The 3-D animated film How to Train Your Dragon continues to play well, taking second place with $10.8 million, bringing its total to $192.4 million since its release a month and a half ago.
The comedy Date Night was third with $7.6 million, lifting its total to $73.6 million. The Back-up Plan was fourth with $7.2 million, bringing its two-week total to $23 million.

Brendan Fraser's wilderness comedy Furry Vengeance rounded out the top five with $6.5 million, slightly below its modest expectations.

Final figures are due Monday.
