Oil markets dip on fallout from Hurricane Harvey; Irma also in focus

By Henning Gloystein

SINGAPORE (Reuters) - Oil prices slipped on Wednesday as crude demand remained subdued on the back of refinery closures following Hurricane Harvey which hit the U.S. Gulf coast 10 days ago.

Market focus was also being drawn to Hurricane Irma, a record Category 5 storm, which is barrelling towards important shipping lanes in the Caribbean.

Although many refineries and pipelines which were knocked out by Harvey are now in the process of restarting, analysts say it will take some time before the U.S. petroleum industry is back to full crude processing capacity.

As of Tuesday, about 3.8 million barrels of daily refining capacity, or about 20 percent, was shut, though a number of the refineries in that group were in the process of restarting. Several others, including Marathon's Galveston Bay and Citgo's Corpus Christi refineries, were running at reduced rates, according to company reports and Reuters estimates.

U.S. West Texas Intermediate (WTI) crude futures were at $48.56 barrel at 0219 GMT, 10 cents below their last settlement.

In international oil markets, Brent crude futures dipped 23 cents to $53.15 a barrel.

Meanwhile, Hurricane Irma is heading for the Caribbean islands of Antigua, Barbuda, Anguilla, Montserrat, St. Kitts and Nevis, the Virgin Islands, Puerto Rico, the Dominican Republic, and parts of Cuba.

"With another hurricane threatening to hit the U.S. coast, traders still remain cautious," ANZ bank said on Wednesday.

Around 250,000 barrels of daily refining capacity in the Dominican Republic and Cuba lie in the currently expected path of Irma, Thomson Reuters Eikon data shows.

"Maximum sustained winds are near 185 mph (295 km/h) with higher gusts. Irma is an extremely dangerous Category 5 hurricane ... Irma is forecast to remain a powerful Category 4 or 5 hurricane during the next couple of days," the U.S. National Hurricane Center (NHC) said.

There is another tropical storm on Irma's heels in the Atlantic, and another one active in the Gulf of Mexico.
