Report: California has most expensive gas in the nation

A new report issued Monday by AAA shows gasoline prices in California are the highest in the nation. 

But there is a shred of good news: West Coast pump prices are stabilizing after the region underwent planned and unplanned refinery maintenance over the past few weeks, AAA reports.

"Reduced supply in the region, amid robust demand, put pressure on pump prices, but the pressure has decreased over the past week as a result of imports and increased production from regional refineries," according to the Monday report. "Prices are expected to continue stabilizing this week, assuming no new supply disruptions occur."

California at $4.07 a gallon is the most expensive market in the country, followed by Hawaii at $3.65.
