Average retail gasoline prices in Yakima have fallen 6.8 cents per gallon in the past week, averaging $3.83/g yesterday, according to GasBuddy's daily survey of 91 gas outlets in Yakima. This compares with the national average that has fallen 1.5 cents per gallon in the last week to $3.64/g, according to gasoline price website GasBuddy.com.

Including the change in gas prices in Yakima during the past week, prices yesterday were 41.8 cents per gallon lower than the same day one year ago and are 29.7 cents per gallon higher than a month ago. The national average has increased 13.1 cents per gallon during the last month and stands 3.1 cents per gallon higher than this day one year ago.

"While the national average has given up some ground to start the driving season, motorists have certainly seen a lot of ups and downs in different areas of the country," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "One thing remains the same throughout the United States, and that is we are still reliant on oil refineries to process crude oil into gasoline. When they go partially offline whether expected or unexpected, there's going to be tightness in gasoline supply, and that has an almost immediately impact at the gas pump.”
