The higher prices are a result of seasonal maintenance at refineries that curtails gasoline production and, in many parts of the country, a switch to summer gasoline blends that reduce emissions but are more expensive to produce.
Here's was going on with gas prices across the country:
- Pump prices rose or fell by a penny or two in many states the past week, but jumped 5 cents a gallon in Alaska and 4 cents in Florida and Kansas.
- Hawaii continued as the most expensive state for gas. AAA listed the average for regular in Hawaii at $3.07, followed by California at $3.01 and Alaska at $2.95.
- South Carolina had the lowest average price for regular at $2.13.
- Alabama, Arkansas, Mississippi, Oklahoma and Tennessee averaged $2.18.
Gas prices also have risen in recent weeks because the price of oil has gone up. Oil, though, fell nearly 5 percent Wednesday amid news that gasoline inventories are above normal. U.S. oil was trading at less than $51 a barrel early Thursday, down from more than $53 a week ago.
