What do you get when you double the gas tax and then add in declining oil inventories along with Hurricane Barry? Prices going up at the pump.

If you think you've noticed that more money is coming out of your pocket for the same amount of gas you bought last month, you're not hallucinating.

Gas prices in and around the Rockford area have gone up over 16 cents in the past week alone.

23 WIFR News:

Rockford's average gas price is currently $2.98, more than a quarter higher per gallon compared to last month. Compared to this time last year, GasBuddy reports gas prices are around 18 cents per gallon higher in the Rockford area.

"For the third straight week, the national average price of gasoline has risen, following oil prices higher due to global geopolitical tensions, declining oil inventories and Hurricane Barry shut in oil production in Gulf waters," said Patrick DeHaan, head of petroleum analysis for GasBuddy.

Rockford's average per-gallon gas price ($2.98) is 10 cents lower than state average ($3.08), but 19 cents higher than national average ($2.79).
