The average weekly gas prices increased nearly a quarter from last week according to AAA Michigan. The current statewide average is just under $3 a gallon with prices averaging $2.96 per gallon.

Of the cities surveyed by AAA, the cheapest prices for self-serve unleaded fuel can be found in the Marquette area, where it's about $2.73 per gallon. The highest averages can be found in the Ann Arbor area where it's about $2.99 per gallon. Gas prices in and around the Flint area are averaging just under $2.96 a gallon.

AAA says the surge in gas prices can be attributed to refinery problems in the Midwest that have limited production and have helped to drive up price.
