The damage to Gulf Coast oil operations still hasn't been assessed, but oil prices have fallen today as Hurricane Gustav weakens.
A stronger dollar gets some of the credit.
Oil tumbled to $111 a barrel as Gustav moved inland after making landfall west of New Orleans. The eye passed about 20 miles from a Louisiana port where huge amounts of oil and gas are piped inland to refineries.
Earlier in the day, crude gained nearly $3 to trade above $118 a barrel. But in late afternoon electronic trading on the New York Mercantile Exchange, light, sweet crude for October delivery was down $4.21 at $111.25.
U.S. trading has been closed today for Labor Day.
In London, October Brent crude was down $4.32 at $109.73 a barrel on the ICE Futures exchange.
Meanwhile, AAA says the average U.S. retail gasoline price was down slightly to just below $3.69 a gallon, after rising slightly more than a penny Saturday.
