Consumers across the country are paying an average of $3.80 per gallon for regular gasoline, according to AAA, an automobile organization.
After prices receded from a high national average of $5 per gallon in June, the price at the pump jumped this week by as much as 60 cents per gallon in some regions.
In California, the average price of gas is $6.38 per gallon, a 62-cent increase over the past week.
The Los Angeles region saw prices increase 15.3 cents last week to an average of $6.26 per gallon.
Several factors are sending gasoline prices north, including a refinery fire in the Midwest, the OPEC consortium hinting that it will significantly cut production when it meets this week, facility maintenance on West Coast refineries and Hurricane Ian affecting refineries along the Gulf of Mexico
