Hurricane Harvey could cause U.S. gasoline prices to rise, with the storm expected to hit a refinery-rich stretch of the Gulf Coast.

Some refineries are expected to shut down until the storm passes. In the Gulf of Mexico, oil and gas operators are evacuating workers from rigs.

Wholesale gasoline futures rose Thursday by 5 cents, or 3 percent, to $1.66 per gallon, and experts say that will quickly show up on service-station signs.

Patrick DeHaan, an analyst with GasBuddy, said Harvey could show up in retail prices as early as Thursday night.
