The average retail gasoline prices in Yakima have fallen 3.7 cents per gallon in the past week, averaging $3.53/g yesterday, according to GasBuddy's daily survey of 91 gas outlets in Yakima. This compares with the national average that has fallen 1.6 cents per gallon in the last week to $3.50/g, according to gasoline price website

Including the change in gas prices in Yakima during the past week, prices yesterday were 49.6 cents per gallon lower than the same day one year ago and are 10.6 cents per gallon lower than a month ago. The national average has decreased 14.5 cents per gallon during the last month and stands 34.7 cents per gallon lower than this day one year ago.

"The slow trend downward in the national average has survived another week," said Senior Petroleum Analyst Patrick DeHaan. "While unprecedented, the decline in the national average certainly has delighted motorists who are used to large spikes in gasoline prices that come with the territory of springtime. With Memorial Day just five weeks away, there is good news for motorists: prices will likely continue to lag behind year ago levels.”
