Gas is off to an expensive start this year ó the most expensive start since 2014. Florida pump prices jumped 10 cents in the past week to hit $2.54 per gallon Monday, 18 cents more than last month, according to AAA The Auto Club Group. Tampa Bay gas was $2.51 per gallon, up 12 cents over the week."It has been anything but a normal January for prices at the pump," Mark Jenkins, AAA spokesperson, said in a release. "Normally, demand slips and supplies build. However, (the) story so far this year has been a rally in oil prices."January prices havenít topped $2.40 since 2014 when fuel was $3.38 per gallon. Nationally, gas was $2.54 per gallon Monday.Donít expect relief just yet, either. With refinery maintenance season coming up in just a few months, gas prices are likely to go up more. Prices could level out, however, if domestic oil production kicks into high gear soon, AAA said.Contact Malena Carollo at [email protected] or (727) 892-2249. Follow @malenacarollo.
