“Sagging U.S. gasoline demand along with continued recovery after Hurricane Ida have helped gas prices edge slightly lower in most states from where they were a week ago. But with Tropical Storm Nicholas threatening another key area of refineries in Houston with significant rain, we could see the decline in prices hit the pause button,” said Patrick De Haan, head of petroleum analysis for GasBuddy. “While Nicholas would appear to be a minor storm, we could see a deluge of water – the same issue that caused some significant damage in Ida’s wake to refineries in Louisiana. Combined with the earlier storm, Nicholas could make things more challenging. However, as gasoline demand has now fallen for four straight weeks, there is more breathing room even if some capacity does temporarily go offline. It’s too early to tell, clearly, but motorists should be aware.”
