Gas prices dipped again during the past week across South Carolina, the only state with the average cost per gallon under $2.

The price dropped 3.1 cents per gallon in the Palmetto State last week to an average of $1.95, according to gas price service GasBuddy. Motor club AAA puts the price a penny higher. That’s about 47 cents less per gallon than this time last year.

Nationally, the price fell 3 cents per gallon during the past week to an average of $2.26 a gallon, according to GasBuddy. AAA puts the price a penny higher. That’s about 51 cents per gallon lower than last year at this time.

The price is expected to edge down nationally over the next week, according to GasBuddy.

“For the week ahead, expect much of the country to see prices continue to trickle lower while the Great Lakes states may see their first price increase in weeks as stations have undercut each other to the point where they begin losing money,” said Patrick DeHaan, senior petroleum analyst for GasBuddy.

“While prices have come down, we now head to the time of year when hurricane season enters the picture,” he said. “In the last couple of years we have seen minimal to no disruption as hurricane season largely went by with no major storms that hit land. Should we see a major hurricane enter the Gulf, gas prices may react.”

In the meantime, motorists are enjoying the lowest average gasoline prices in 11 years, which could carry over into Labor Day, DeHaan said.

In South Carolina, the lowest average price per gallon can be found in the Upstate at $1.91, according to AAA. The average price in Charleston-North Charleston stands at $1.95 per gallon.

In the Charleston area, the price on Tuesday ranged from $1.78 per gallon in West Ashley to $2.14 per gallon in Mount Pleasant.
