The end of summer generally means a drop in gas prices. And while some prices have held steady for the past few weeks, some parts of  the country have seen prices jump.

The national average went up to $3.84/gallon according to AAA.

Prices rose in August because of Hurricane Isaac forcing gas and oil companies to shut off their facilities. But that price was expect to drip once those came back online.

An analyst says the price is delayed because the hurricane hit close to Sept. 15.

In South Bend, residents can expect to pay about $3.97/gallong. And in Michigan, some stations are selling gas at $4.06/gallon.
