That's well above the average for the county, which rose by 2.6 cents to $4.848 per gallon.
That was the county's 19th record high price in the last 22 days. It was also the largest one-day jump since Feb. 2, when the average price rose by 2.8 cents.

"Also, this week's U.S. Energy Information (Administration) report indicates that West Coast gasoline supplies are at their lowest levels of 2022, which could also add to upward price pressure.''
