A recent press release from AAA stated, “Pump prices have dipped to match the summer of 2021, the last time seasonal gas prices were this low. Meanwhile, a low-pressure system off the Gulf Coast has the potential—albeit low—to strengthen, and it’s something to watch as it moves westward. This time of year, tropical activity can have an effect on gas prices if there’s damage to refineries or if local flooding affects gasoline distribution or demand.”
