NOTTINGHAM, MD—For the fourth consecutive week, the national average price of gasoline has risen, posting a 6.4 cent per gallon gain from a week ago to $3.03 per gallon on Monday according to GasBuddy data compiled from more than 11 million individual price reports covering over 150,000 gas stations across the country.

The national average now stands 16.8 cents higher than a month ago and $1.17 per gallon higher than a year ago. The national average price of diesel has risen 6.3 cents in the last week and stands at $3.17 per gallon.

“The national average gas price surged last week thanks to big price jumps in Southeastern states due to the previously shut down Colonial Pipeline, but most areas outside that region saw smaller fluctuations,” said Patrick De Haan, head of petroleum analysis for GasBuddy. “With the pipeline now back in service, I expect prices to come down in the hardest hit states, specifically the Carolinas, Georgia, Tennessee, Florida and Virginia. The drops should lead the national average to soon fall back under the $3 per gallon mark, but motorists shouldn’t get too excited – prices may start to head higher in a few weeks should Memorial Day gasoline demand be red hot. In addition, motorists in the affected areas should see outage numbers continue to decline this week, especially early in the week when gasoline demand tends to be lowest. I’m optimistic that there will be enough recovery by Memorial Day for motorists in these states to fill up without having to search for gasoline.”
