ST. PETERSBURG, Fla. — Florida gas prices have held steady for the past week, but prices at the pump may increase this week.

"Florida drivers may see gas prices rise another 10 cents this week," said Mark Jenkins, spokesman, AAA - The Auto Club Group. "Both planned and unplanned refinery maintenance, rising demand, and the switch to summer gasoline continue to contribute to the seasonal springtime jump at the pump.

"Based on current conditions, gas prices will likely peak sometime between Cinco de Mayo and Memorial Day weekend."
