U.S. gasoline prices have risen again but at a slower pace.

The average price of regular jumped 3 cents a gallon in the past two weeks to $2.87 a gallon.

Analyst Trilby Lundberg says it's the smallest hike in nine weeks. The average is 82 cents a gallon lower than a year ago.

The highest price in the continental United States was $3.62 in San Diego. The lowest was $2.45 in Tucson, Arizona.

The average California price was $3.49, down 17 cents a gallon over two weeks.

The average national price for midgrade gas was $3.07, with premium going for $3.24.

Lundberg says Sunday that with a good gas supply and stable crude oil prices, gasoline prices could stop rising and might even drop in the next two weeks.
