On the morning after the storm made landfall, gas prices fell nationally by almost a penny per gallon. The following day, they fell another penny.
The average price of a gallon of regular gasoline fell Tuesday by about a penny to $3.53. That's more than 11 cents lower than a week ago. This, even as refineries in the east were shut down or under reduced operations because of the huge storm.
After peaking at $3.87 a gallon on Sept. 14, average gas prices nationally have declined steadily to $3.52, as of Tuesday, according to the AAA Daily Fuel Gauge Report. Ash predicts they'll continue to fall through Christmas, reaching a low of somewhere between $3.10 cents and $3.30 a gallon.
