Average retail gasoline prices in Yakima have risen one cent per gallon in the past week, averaging $3.51 per gallon, according to GasBuddy's daily survey of 91 gas outlets in Yakima.

The national average has increased 2.6 cents per gallon to $3.50 per gallon over the same time frame.

Prices are 14.3 cents per gallon lower than the same day one year ago and 25.2 cents higher than a month ago. The national average has increased 15.5 cents per gallon during the past month and stands 15.1 cents lower than one year ago.

"The national average has unsurprisingly continued it's march higher, and for the sixth consecutive week, motorists have faced rising gasoline prices," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.

"While the rate that gasoline prices may slow nationally this week, I don't yet believe we've seen the peak in prices. Refineries are in the middle of one of their two major yearly maintenance seasons. That means as refineries wrap up their work in April, we could see restarting issues, which could bring the spikes in gasoline prices we're nearly accustom to seeing every spring," DeHaan said.
