As Tropical Storm Isaac approaches the Gulf Coast, many oil refineries have closed, resulting in rising gas prices, according to CNNMoney.
The national average could jump by as much as 10 cents a gallon as a result of Isaac disrupting oil supplies, Tom Kloza, chief oil analyst for the Oil Price Information Service, which tracks gas prices for AAA, told CNNMoney. He doesn't expect the price jump to last very long unless the storm causes lasting damage.
The national average for a gallon of regular gasoline rose 0.6 of a cent to $3.756 on Tuesday, according to a survey by the motorist group AAA. But prices in the Gulf states rose by more than that as Louisiana saw an increase of 2.5 cents to $3.642, 1.3 cents to $3.581 in Alabama and 2 cents to $3.563 in Mississippi.
Gas prices jumped 7 percent in August before the storm, according to the article. But with Isaac, the national average has jumped 2.6 cents since Friday.
