YAKIMA — Average gasoline prices in the Yakima area have fallen 5.2 cents a gallon in the past week, averaging $3.25 as of Sunday, according to GasBuddy.com, a website that tracks prices locally and across the country.

Meanwhile, gas prices nationally inched up slightly less than a penny, according to the website.

In Yakima on Sunday, prices were 15.6 cents per gallon lower than the same day a year ago and 4.8 cents lower than a month ago. The national average has increased 1.9 cents per gallon during the last month and stands at 8.9 cents per gallon lower than on that day one year ago.

“While gasoline prices have seemingly remained virtually unchanged in many areas across the U.S. in the last week, that has meant that some areas are still seeing prices remain much lower than a year ago,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.

“The national average now lags prices one year ago by 9 cents per gallon, which is a more optimistic start to the year than I would have expected,” DeHaan said.
