U.S. Gulf Coast Faces Hurricane Hit as Laura Gains Power

- Marco loses power as it nears Louisiana, U.S. ends warnings

Tropical Storm Laura is poised to become a powerful hurricane before making landfall Thursday, posing a threat to oil and natural gas infrastructure across the Gulf Coast.

A hurricane watch has been posted from Port Bolivar, Texas, to west of Morgan City, Louisiana, in anticipation of Laura's arrival, the National Hurricane Center said in an advisory at 11 p.m. New York time. Forecasts are split on whether Laura becomes a major hurricane with winds in excess of 111 miles (179 kilometers) per hour or not. Another storm, Marco, lost so much power as it approached the coast that it will likely fall apart.

“Laura is forecast to reach the northwestern Gulf Coast as a hurricane late Wednesday and early Thursday,” Dan Brown, a meteorologist at the center, wrote in his forecast. “Do not focus on the details of the official forecast” given uncertainty in predictions to three days out, he said.

Laura's winds are expected to hit 110 mph, making it a Category 2 hurricane just shy of Category 3 strength on the five-step Saffir Simpson scale.

The tropical threat has already prompted 82% of oil output and 57% of natural gas production in the Gulf of Mexico to be shut , according to the Interior Department's Bureau of Safety and Environmental Enforcement. If Laura becomes a Category 3, it would be the first major Atlantic hurricane of 2020.

Gulf Coast refineries and petrochemical plants are often located in low-lying areas vulnerable to flooding. In 2017, an Arkema SA chemical plant about 25 miles (40 kilometers) east of Houston had a fire and explosion after it was flooded by Hurricane Harvey. In September, Exxon shut its Beaumont refinery in Texas because of flooding from Tropical Storm Imelda.

Laura almost certainly won't be as damaging as Harvey, however. Harvey hit Texas as a Category 4 storm and then got pinned in place by larger weather patterns, causing it to send record rains across the eastern half of the state for days. Laura may pack a severe punch at landfall, but it will quickly exit the area, reducing the potential for lingering effects. The last hurricane to hit Texas was Hanna, just under a month ago.

Energy platforms in the Gulf of Mexico that account for as much as 17% of America's oil production and about 3% of gas output are designed to withstand storms of this magnitude; they regularly shut and restart as systems pass through.

Laura could cause problems for refineries and fuel-distribution hubs from Houston to Louisiana, said Jim Rouiller, lead meteorologist with the Energy Weather Group. Offshore platforms were retrofitted after 2005's Hurricane Katrina to endure stronger storms, but onshore flooding could threaten the 45% of American fuel-making capacity that's located along the Gulf Coast, as well as more than half the nation's gas processing.

“The big issue is if it hits any of the refineries -- present track is right over Lake Charles and 10% capacity at risk,” said Chuck Watson, a disaster modeler with Enki Research. “A wobble puts the north Texas coast in play.”

Motiva Enterprises LLC and Valero Energy Corp. are shutting their Port Arthur, Texas, refineries ahead of Laura, while Total Port Arthur is cutting rates more than 50%. Exxon Beaumont is weighing a shutdown, people familiar with planning say.

The city of Port Arthur will order some residents to flee the storm starting Tuesday, according to the Houston Chronicle. Jefferson County put in place a mandatory evacuation order for all except essential personnel such as employees of oil terminals, pipelines, oil-supply facilities, hospitals and utilities, it said in a statement.

Liquefied Natural Gas

Laura is poised to menace the epicenter of the U.S. liquefied natural gas export industry, where terminals are located. Cheniere Energy Inc.'s Sabine Pass, Sempra Energy's Cameron LNG in Louisiana and Freeport LNG Development's terminal in Southeast Texas -- account for about 75% of U.S. LNG export capacity, or more than 51 million tons per a year.

“Although these terminals are built to withstand hurricane force winds, the storms will prevent any new vessels from approaching,” Daniel Myers, an analyst at Gelber & Associates, said in report Monday.

Western sugarcane in Louisiana between Lake Charles and Lafayette will be the most at risk from Laura, said Drew Lerner, president of World Weather Inc. in Overland Park, Kansas. Things would be worse if the storm veers more to the east.

For cotton crops, some parts of western Mississippi Delta area, central and interior parts of Arkansas also could be impacted, he said.

Other impacts include:

  • Kinder Morgan has suspended operations at International Marine Terminal in Port Sulphur, Louisiana, and reduced operations at Harvey Terminal in Harvey, Louisiana.
  • Houston pilots are planning to halt inbound boardings from 4 p.m. local time in advance of Tropical Storm Marco, according to a bulletin obtained by Bloomberg.
  • Chevron shut its Fourchon and Empire oil terminals in Louisiana, and has also shut Gulf of Mexico pipelines.
  • Bunge has ceased operations at its grain-export facility in Destrehan, Louisiana, while Cargill has suspended operations at grain-exporting facilities in Westwego and Reserve, Louisiana.
  • Noble Corp. is moving two offshore rigs , while BP Plc evacuated employees from four platforms.
  • Energy Transfer LP shut in its Stingray Pipeline, which hauls gas from offshore fields to Louisiana.
  • The Louisiana Offshore Oil Port, a major crude import hub, has suspended marine terminal operations.
  • Royal Dutch Shell Plc evacuated employees and idled output at the majority of its Gulf operations .

Texas Governor Greg Abbott, Louisiana Governor John Bel Edwards, and Mississippi Governor Tate Reeves have all declared emergencies. Laura has already killed at least nine people in Haiti and the Dominican Republic, the Associated Press reported.

Thirteen storms have now formed across the Atlantic this year, including five that hit the U.S. It is the fastest start to a hurricane season in records going back to 1851, said Phil Klotzbach, a storm researcher at Colorado State University.
