“While gas prices fell in more states than they rose last week, the West Coast continues to face challenges, with Oregon and Washington seeing some of the largest increases due to regional infrastructure issues,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The good news is that the transition to cheaper winter gasoline begins tomorrow across most of the nation, and with improvements underway in the West Coast market, I expect that average gas prices will continue to decline in the weeks ahead in most states— assuming hurricane season remains quiet.”
