WASHINGTON -- Gasoline is getting a bit more expensive ahead of the Labor Day weekend.
According to the auto club Triple-A, the average price of a gallon of gas rose by 1.8 cents overnight to $3.56. That's the biggest overnight increase in six weeks.
Gas is starting to track the rising price of oil, which reached a two-year high this week on fears of supply disruptions in the Middle East. During August, oil has risen 5 percent on worries about escalating violence in Egypt and the possibility of a U.S. strike against Syria.
A Triple-A spokesman says it's "increasingly likely that pump prices will rise in the coming days" because of concerns about Syria and possible consequences elsewhere in the Middle East.
Still, Michael Green points out that Labor Day gas prices were 27 cents higher last year, after Hurricane Isaac struck the Gulf Coast in late August and refinery production lagged.
