Gasoline exports from the region rose sharply this week after a wave of cargo buying that followed Hurricane Harvey last week. Around 700,000 tonnes of gasoline and blending components were set to leave on the route, traders said.
Exports to the US East Coast have nevertheless slowed in recent days as traders wait to see the impact of Hurricane Irma, which is set to make landfall in Florida.
Irma is forecast to hit the densely populated Miami region and severely damage oil infrastructure, according to Reuters weather analysts.
Refiners including Exxon Mobil Corp XOM.N and Motiva Enterprises purchased fuel on Thursday to compensate for lost output from plants shut since Hurricane Harvey hit the US Gulf Coast last month, traders said.
Oil and petrochemical plants along the US Gulf Coast intend to go ahead with plans for near record spending on expansion next year, despite Hurricane Harvey driving up labour costs and slowing work, experts said.
