ATLANTA (AP) — Gasoline prices rose several cents overnight amid continuing fears of shortages in Texas and other states in the aftermath of Hurricane Harvey’s strike on the Gulf Coast. The national average for a gallon of regular gas rose in one day from $2.45 Thursday to $2.52 Friday, the American Automobile Association reported . At least two major pipelines — one that ships gasoline across the southern United States and to New York, and another that flows north to Chicago — have been slowed or stopped because of flooding and damage. Gas prices rose at least 15 cents in 24 hours in several metropolitan areas including Dallas; El Paso, Texas; Athens, Georgia; and Dayton, Ohio, AAA reported Friday. The average price of a gallon of gas had soared by at least .10 cents in eight states since Thursday: South Carolina, Ohio, Delaware, Maryland, Georgia, North Carolina, Virginia and Texas. Among those states, the highest 24-hour rise on average was in South Carolina, AAA reported.
