Forecasters: Isaac won't end Midwestern drought

A state of emergency is declared in four states as Tropical Storm Isaac is gaining strength moving across the Gulf Coast.

Forecasters believe it doesn't look like the rain will be enough to break the drought here in the Midwest.

New reports show some of the hardest hit areas in the Midwest will only get 2-6 inches of rain when the storm slams into the Gulf.

Experts say the backlash will bring enough rain to help ease the drought, but not eliminate it.
