Florida gas prices are rising at a record pace.

Over the last 12 days, the stage average rose $0.84, according to AAA.

That’s the fastest pace in four years, with the new average $0.27 higher than a week ago, $0.84 higher than a month ago, and $0.61 higher than this time last year. Some individual counties in the state saw price hikes of nearly a dollar in the last two weeks.

The conflict in Iran has created extremely volatile fuel markets. The price of oil had continued to rise since hostilities started, with the recent surge driven by concerns over global supply distribution and instability.

Higher crude oil and whole gasoline costs are being passed to consumers, and if the prices remain elevated, state prices are expected to trend higher through the week.

“How high prices ultimately go, will depend on how long this conflict continues and whether there are further effects on global fuel supplies,” said AAA spokesperson Mark Jenkins.

Osceola is the priciest county in Central Florida at $3.76 a gallon with Volusia at $3.75, Brevard at $3.74, Seminole at $3.72, Orange at $3.71 and Lake at $3.69.

The priciest county in the state is Monroe County, which includes the Florida Keys. It’s the first to break the $4 a gallon mark, average $4.02 a gallon.

The most expensive metro markets are West Palm Beach-Boca Raton ($3.89), Naples ($3.79) and Gainesville ($3.79).

The least expensive metro markets are Crestview-Fort Walton Beach ($3.41), Panama City ($3.44) and Pensacola ($3.48).
