PHOENIX -- Gasoline prices for Arizona have hit a five-month high.
Officials with Triple-A Arizona said Thursday that the average statewide price for unleaded regular gasoline is $3.74 a gallon. That's more than 11 cents higher than last week and a rise of 56 cents since January.
This week's national average is $3.78 per gallon, up by less than a penny from last week.
Triple-A analysts say refinery maintenance and the higher cost of crude oil have kept gasoline prices high so far this year.
Tucson has the lowest average gasoline price in Arizona at $3.53 a gallon while Yuma has the highest at $3.86.
Wyoming has the lowest average gas prices in the continental U.S. at $3.28 a gallon with California having the highest at $4.23 a gallon.
