Arizona motorists are paying more at the pump again this week.

Officials with AAA Arizona said Thursday that the average statewide price for unleaded regular gasoline is $3.34 a gallon. That's more than 13 cents higher than last week.

This week's national average is $3.55 per gallon, also up by more than 13 cents from last week.

AAA analysts say the price rise is typical for this time of year in Arizona as spring approaches and demand for gasoline starts to pick up.

Tucson has the lowest average gasoline price in Arizona at $3.14 a gallon, while Flagstaff has the highest at $3.43.

Wyoming has the lowest average gas prices in the continental U.S. at $2.99 a gallon.

California has the highest at $3.98 a gallon.
