PHOENIX (AP) -- Gasoline prices around Arizona are slightly lower at the pump this week. Officials with Triple-A Arizona said Thursday that the average statewide price for unleaded regular gasoline is $3.23 a gallon. That's down by less than a penny from last week. This week's national average is at $3.32 per gallon, up by nearly 6 cents from last week. Triple-A analysts say prices are expected to rise in the coming weeks due to seasonal factors. Tucson has Arizona's lowest average gasoline price at $3.13 a gallon and Flagstaff has the highest at $3.34. Montana has the lowest average gas prices in the continental U.S. at $3.05 a gallon with California having the highest at $3.66 a gallon.
