Gasoline prices at the pump around Arizona are lower for the eighth consecutive week and now are at an 11-week low.
Officials with Triple-A Arizona said Thursday that the average statewide price for unleaded regular gasoline is $3.45 a gallon.
That's a decrease of nearly a nickel from last week.
This week's national average is $3.52 per gallon, up by more than a penny from last week.
Triple-A analysts say production issues and weather are contributing to higher prices in other parts of the country.
Tucson has the lowest average gasoline price in Arizona at $3.23 a gallon while Flagstaff has the highest at $3.68.
South Carolina has the lowest average gas prices in the continental U.S. at $3.22 a gallon with Illinois having the highest at $3.95 a gallon.
