Tropical Storm Isaac is expected to reach hurricane strength on Tuesday, before reaching the swampy coast of southeastern Louisiana.
Residents of New Orleans are hunkered down behind levies that were fortified after Hurricane Katrina struck seven years ago Wednesday.
Isaac's impact on Iowa is twofold: weather and gas prices.
The latest forecast shows remnants of the storm could reach southeastern Iowa by the weekend. Other possible tracks take the storm well east into Illinois and Indiana.
AAA said the storm could also impact our gas prices, bringing $4 a gallon gas by Labor Day.
The main reason for the price jump is the oil rigs in the Gulf of Mexico provide a quarter of the nation's fuel and Isaac forced them to shut down.
Right now, AAA said Iowa drivers are paying an average of $3.69 for regular.
