Tropical Storm Isaac to blame for gas price hike
Gas prices could be affected by Tropical Storm Isaac.
Oil refineries owned by Marathon, Phillips 66, and Valero are bring forced to close in the wake of this disaster.
This means that gas prices could rise between five and 10 cents over the next week.
These refineries will take at least a week to get up and operating again after the storm, so gas prices could be high for awhile.
