Gas prices in Arizona have leveled off after weeks of declines. Triple-A Arizona says the price of gas is virtually unchanged at $2.42 a gallon. In Flagstaff, gas prices were up nearly a cent to $2.62 a gallon. Some stations are selling gas for $2.45 a gallon and lower. In Prescott, gas was down a cent to $2.69 a gallon. However, some stations are selling gas for $2.55 and lower. Officials say prices at the pump are expected to rise in the short term because of crude oil supplies and refineries that are gearing up for spring gas production.
