Michiganders vacationing in Traverse City saw gas prices reach $3.30 over the weekend.

“Michigan drivers are seeing higher prices at the pump this week,” Howard Hughey, a spokesperson for AAA-The Auto Club Group said, in Monday’s news release. “If demand continues to increase, gas prices may rise further.”

That’s a hike of 12 cents from a week ago.

According to AAA’s report Michigan drivers are now paying an average of $3.27 per gallon for regular unleaded. This price is 16 cents more than this time last month but still 32 cents less than this time last year.

Those who filled their 15-gallon tank were paying an average of $49, although this was about $8 lower than the average paid last July.

According to new data from the Energy Information Administration (EIA), gasoline demand increased from 8.64 million barrels a day to 9.15. Total domestic gasoline supply decreased from 232.1 million barrels to 229.5. Gasoline production increased, averaging 9.9 million barrels per day.

At the close of Wednesday’s formal trading session, West Texas Intermediate, which is a type of crude oil that serves as a median for all oils, increased 5 cents to settle at $68.38 a barrel. The EIA reports that crude oil inventories increased by 7.1 million barrels from the previous week. At 426 million barrels, U.S. crude oil inventories are about 8% below the five-year average for this time of year.

If you compare prices to last week, Metro Detroit’s average daily gas price increased to an average of $3.25 per gallon, which is about 5 cents more than last week’s average but still 29 cents less than this same time last year.

AAA’s state and metro gas averages showed:

• Most expensive gas price averages: Saginaw ($3.33), Traverse City ($3.32), Lansing ($3.31)• Least expensive gas price averages: Marquette ($3.06), Benton Harbor ($3.23), Metro Detroit ($3.25)
