NPR's business news starts with an eye on oil prices.
Isaac is not expected to grow beyond a Category 1 hurricane and that is easing some concerns it could damage oil and gas refineries along the Gulf Coast.

Depending on Isaac's severity, analysts say gas prices could go up by about 10 cents or so in the coming weeks. Transcript provided by NPR, Copyright NPR.
