The latest storm threat to the US oil production is pumping up prices. As Hurricane Rita gets closer to the rigs and refineries around the Gulf of Mexico, the cost of crude is going higher. In the US it has been over $68 a barrel and Brent is above $65. Rita is on track to hit land around a coastal cluster of refineries in Texas and Louisiana. Because that is where the oil comes ashore, a big percentage of US refineries are in the Gulf of Mexico.
