COPPELL, Texas — Retail gasoline prices in Texas and across the country spiked by at least a dime following disastrous Hurricane Harvey.

AAA Texas on Thursday reported the average price at the pump statewide was $2.26 per gallon. That’s 12 cents higher than a week ago, when Harvey threatened Texas, and 4 cents above Wednesday’s price.

The association survey says U.S. gasoline prices Thursday averaged $2.45 per gallon — that’s 10 cents higher than a week ago and a nickel increase since Wednesday.

Harvey made landfall in South Texas last Friday, leading to coastal flooding and swamping of much of Houston. Parts of Beaumont and Port Arthur also flooded as Harvey lost strength and moved into Louisiana.

Dallas had the most expensive gasoline in Texas on Thursday at an average $2.37 per gallon.
