Hurricane Isaac is affecting gas prices across the state.
The average price of a gallon of unleaded is going for $3.66 in Austin – that's up ten cents from last week.
AAA Texas says the main reason for the price increase is that several refineries along the Gulf Coast closed before Isaac hit land. But analysts say gas prices will come down if the refineries re-open without storm damage.
The average price in the state is $3.64 – that's still well below the national average of $3.80.
AAA Texas says, despite the weather and the higher gas prices (19 cents higher in Austin than this time last year), 2.4 million Texans are expected to travel for the upcoming Labor Day weekend.
