PORTLAND — A price-monitoring website says average retail gasoline prices in Maine have risen 3.6 cents per gallon in the past week to $3.72.

MaineGasPrices.com says Sunday’s average price was $1.05 per gallon higher than it was the same day one year ago, but 7 cents per gallon lower than a month ago.

It also compares with the national average, which has increased 5.9 cents per gallon in the last week to $3.67 per gallon.

Analyst Patrick DeHaan says gasoline prices continue to slowly advance, but with major storms impeding the activity of refineries, that shouldn’t come as a shock.
