PHOENIX -- Gasoline prices around Arizona are higher at the pump this week.
Officials with Triple-A Arizona said Thursday that the average statewide price for unleaded regular gasoline is $3.19 a gallon. That's an increase of more than 4 cents 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 the rise is due to elevated crude prices and regional refinery issues.

Montana has the lowest average gas prices in the continental U.S. at $3 a gallon with Connecticut having the highest at $3.71 a gallon.
