Just ahead of the Labor Day holiday, AAA Michigan reports that the statewide average daily gas price has increased seven cents from last week. Michigan's current statewide average is about $2.39 per gallon.

Of the ten Michigan metro areas surveyed by AAA for self-serve unleaded fuel prices, the lowest prices for the second week in a row can be found in Traverse City area where gas is averaging $2.32 a gallon. The highest averages can be found in the Ann Arbor area at nearly $2.46 per gallon. Gas prices in and around the Flint area were averaging slightly less than the statewide average at $2.38 per gallon.

AAA says for the second straight week, Michigan ranks ninth in the nation for the most expensive gas prices and that while prices in recent weeks have been a mixed bag of increases and decreases, regional prices have moved universally higher. The volatility has been added to by operations at a Midwest refinery which has been slow to come back on line following production problems.
