SAN DIEGO (KGTV) -- Gas prices in Southern California continue to rise sharply as prices throughout the rest of the U.S. continue to fall.
According to GasBuddy, the national average is down two cents, currently costing $2.65 per gallon.
In California, the average as of Sunday is $3.98 per gallon and could hit $4 by late Sunday or Monday, GasBuddy says.
In San Diego County, the average price per gallon has increased by more than 40 cents over the last 13 days, AAA reports.
The jolting increase in gas prices is a result of lower supplies caused by maintenance issues at several California refineries.
The issues are reportedly affecting the Chevron and Marathon refineries in Los Angeles County at the same time.
It's unclear when normal operations will resume.
