Gas prices are soaring once again in Arizona [Video]

(Stacker) – Refinery troubles are driving the average price of gasoline up at the quickest pace in months, according to AAA data.

Drivers in Midwestern states are seeing the largest impact after a Whiting, Indiana, BP refinery shut down two weeks ago due to a power outage. Reuters reported that the shutdown could extend through the month of February while it’s inspected for damage.

A tighter supply of gasoline over the past week has also contributed to the swings in price.

Once the refinery is back in operation again, “further increases at the pump should revert to slower and lower seasonal gains,” according to a statement from AAA spokesman Andrew Gross this week.
