How gas prices have changed in Louisiana in the last week

The nationwide price for a gallon of gasoline tumbled lower over the past week, reaching levels 50 cents lower than they were a year ago.

Those prices could dip even lower in the next month as refineries are anticipated to switch over to producing a cheaper winter blend of gasoline in mid-September. The seasonal switchover, which happens every year around the same time, tends to lower the average cost of gas by 15 to 30 cents, according to GasBuddy.

While it worries investors, conflict in the Middle East has yet to manifest in higher gas prices, and the hurricane season has yet to produce any storms that have damaged refinery infrastructure. That's despite warnings from experts that this year's hurricane season could be especially active.
