TERRE HAUTE, Ind. (WTHI) - Indiana and Illinois drivers are spending more at the pump and experts say prices will continue to climb.
Experts with GasBuddy.com say areas of the Midwest have seen the fastest rising prices in recent days.
Prices locally range from $2.50 to $2.80 per gallon.
According to experts, prices are creeping up due to simple supply and demand.
The supply of gasoline is low due to several factors like Hurricane Harvey impacting refinery maintenance and a leak in the Explorer Pipeline.
Drivers are being warned to prepare to pay more.
One Terre Haute woman says she uses her car all day for work and the increase hurts.
Tessa Wampler says, "The different gas stations even being at different prices, doesn't really make a lot of sense."
Hoosier drivers are also paying more due to a recent increase to the gas tax to fund more than a billion dollars in highway improvements.
GasBuddy is predicting Indiana drivers could pay up to $2.95 a gallon while drivers in Illinois could see prices above three dollars in some areas.
