Jamestown area gas prices have jumped 9 cents this week to $3.79 per gallon, up 17 cents from this time last year.
The national average price for regular unleaded gasoline is $3.67 per gallon.
This price is 3 cents more than a week ago, nine cents more than one month ago and 20 cents more than the same day last year.
Prices in the Northeast and Mid-Atlantic were relatively stable this spring; however retail prices in 10 states in these two regions (Del., Conn., Maine, N.J., N.H., Md., Mass., R.I., Penn. and N.Y.) have jumped by at least 20 cents in the last 14 days. This sharp increase has been attributed to production concerns, most notably due to operational issues at Irving's Saint John Refinery in Canada, which have been a catalyst for sharply higher pump prices in recent weeks. While not yet confirmed, market analysts believe that the Irving refinery is unlikely to return to full production until after the conclusion of the summer driving season in early September, which would be expected to keep upward pressure on prices.
