The national average price for a gallon of gasoline has risen 1.6 cents per gallon over the last week to $2.84 per gallon, according to GasBuddy data compiled from more than 10 million individual price reports. The average price of diesel also rose, tacking on 1.4 cents to an average of $3.17 per gallon.

“Last week saw a brief and fairly tame rise in the national average, brought on mainly by a select few states where gas prices tend to be volatile. Overall, it was a mostly stable week with some up and down movement state-by-state, but now we await the changeover to winter gasoline that happens this Saturday for some relief at the pump,” said Patrick DeHaan, head of petroleum analysis for GasBuddy. “While Hurricane Florence may pose fuel-related challenges for areas of the East Coast, there is little to no threat to refineries at this time and is thus unlikely to bring measurable impact to the national average price of gasoline, but could bring supply challenges to several states, depending on levels of evacuations and timing of them. Hurricane season aside, gasoline demand will likely drift lower nearly countrywide, putting some additional downward impact on prices in most communities over the next few weeks.”

Oil prices have moved lower as a barrel of West Texas Intermediate this morning fetched $67.99 per barrel, a drop from $71.18 a week ago, and could lead gas prices to follow that track in the next week. Hurricane Florence, meanwhile, poses little threat to refineries and is unlikely to bring widespread price impacts, but may have localized impacts, mainly supply disruptions as motorists evacuate the Carolinas.
