Gas prices soaring in Iowa - KWWL.com

Average retail gasoline prices in Iowa have risen more than seven cents a gallon in the past week, now costing an average of $3.81.   This compares with the national average that has increased just more than a penny per gallon in the last week, also now averaging $3.81, according to gasoline price website IowaStateGasPrices.com.

Prices now sit 13.6 cents per gallon higher than this time last year, and are 15.1 cents per gallon higher than last month.  The national average has increased 14.6 cents per gallon during the last month and stands 14.9 cents per gallon higher than this day last year.

"Even with Hurricane Isaac long gone, the oil industry is still bringing capacity back online- at refineries and oil rigs, which is keeping pressure on prices," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.  "Supply remains tight across the country as we slowly approach the transition to winter-spec gasoline, but I continue to be firm in believing that the national average will start to decline towards the end of September, as is typically the case."
