PROVIDENCE, R.I. — Gas prices remain on the rise in Rhode Island, as several oil refineries on the Gulf Coast continue to be affected by the destruction of Hurricane Harvey.

AAA Northeast says its weekly survey on Monday found the average price of a gallon of regular unleaded gas was $2.73, up four cents from last week.

That’s six cents above the national average of $2.67 per gallon.

It’s also 55 cents higher than this time last year, when the average price was $2.18 per gallon. That’s an increase of 25 percent.

AAA’s Lloyd Albert says gas supplies dropped last week. He says he expects prices to start to decrease later in the month, as pipelines and refineries return to full operations.
