The average price of a regular gallon of gas jumped 13 cents in the past two weeks to $2.33, repeating the hike seen two weeks prior for a total 26 cents rise in the last month.

Industry analyst Trilby Lundberg said Sunday that the rise follows months of crashing prices and is still $1.08 per gallon less than a year ago. She attributed the rise to an increase in crude oil prices in mid-January and labor strikes at several refineries.

In Southern California, prices also rose following an explosion at ExxonMobil’s Torrance refinery.

Los Angeles saw prices jump more than 35 cents making it the highest-price gas in the lower 48 cities surveyed, at $2.91.

The low average was in Salt Lake City at $1.91.
