Average retail gasoline prices in Georgia have risen 2.3 cents per gallon in the past week, averaging $3.70/g Monday. This compares with the national average that has increased 5.2 cents per gallon in the last week to $3.71/g, according to gasoline price website AtlantaGasPrices.com.

In Covington Tuesday, the average gas price was $3.65 with the lowest price, $3.61, at a Shell station on Covington Road. The highest gas price Tuesday was at a BP near Stone Creek Drive.

Including the change in gas prices in Atlanta during the past week, prices Monday were 30.5 cents per gallon higher than the same day in 2011 and are 19.4 cents per gallon higher than a month ago.

The national average has increased 27.8 cents per gallon during the last month and stands 24.1 cents per gallon higher than this day one year ago.

"Gasoline prices have spiked considerably higher in virtually every area over the last two weeks," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "The rise in price is so unbelievable that we may have to revise upward our previous gasoline forecast that had called for a national average of between $3.75 to $4.15 by mid-May, as the national average already stands at nearly $3.72/gallon," DeHaan said.
