CHARLESTON, S.C. (WCIV) -- Average gas prices in South Carolina dipped again over the past week to $3.13 per gallon, according to

The state average fell1.9 cents, the group said.

Nationally, averages fell 3.7 cents per gallon in the last week to $3.39 per gallon, according to price-tracking website

Prices are still nearly 10 cents above the average price a year ago and almost one cent above the average price one month ago. GasBuddy said the average prices nationally are also 10 cents above the price one year ago.

"While the national average continues to fall, we've done the math- the yearly average in 2012 is all but guaranteed to set all time record highs," said Senior Petroleum Analyst Patrick DeHaan. "We still stand at $3.63/gal for a yearly average, and gasoline prices would need to average no more than $2.35/gallon for every day left in 2012 for the national yearly average to drop below 2011, something that appears impossible. In the meanwhile, we have lowered our forecast for Christmas gasoline prices to average between $3.25-$3.35/gallon."
