Hurricane Helene, which is forecast to intensify as it heads for a late Thursday landfall in Florida, has shut in about 29pc of US Gulf of Mexico oil output.
Around 511,000 b/d of US offshore oil output was off line as of 12:30pm ET, according to the Bureau of Safety and Environmental Enforcement (BSEE), while 313mn cf/d of natural gas production, or 17pc of the region's output, was also off line. Operators have so far evacuated workers from 17 offshore platforms.
Helene was last about 110 miles north-northeast of Cozumel, Mexico, according to a 2pm ET advisory from the US National Hurricane Center, with maximum sustained winds of 80 mph. Helene is expected to be a major hurricane, with winds of at least 111mph, when it reaches the eastern Florida coast on Thursday evening.
"A turn toward the north and north-northeast with an increase in forward speed is expected later today through Thursday, bringing the center of Helene across the eastern Gulf of Mexico and to the Florida Big Bend coast by Thursday evening," the center said.
