JACKSONVILLE, Fla. - Jacksonville gas prices are up about four cents compared to a week ago. The average price for a gallon of regular gas is at $3.68, while the national average is $3.74.
Gregg Laskoski, senior petroleum analyst for GasBuddy.com, said Tropical Storm Isaac is the "catalyst behind all this."
"It's just the potential of disrupted supply chains, disrupting deliveries, the potential for power outages," he said.
All of that is affecting the supply of gas, and in turn retail prices are going up.
Laskoski said he's already hearing reports of wholesale fuel prices throughout the Gulf Coast region going up significantly.
"But price spikes don't last for long," Laskoski said.
He thinks prices will flatten out and then begin to dip by mid to late September, when refineries make the switch to winter blend gasoline.
Laskoski said we can't ignore the situation in the Middle East. He said Israel and Iran are moving closer to a point where there may be an attack, and that can have an effect on gas prices at all.
