The remnants of Hurricane Isaac brought some much-needed relief to several key drought-stricken farm states last week. But for the most part, Iowa was not among them. In fact the weekly U.S. Drought Monitor map shows that parts of northwest Iowa slipped into the category of "exceptional drought", the most severe category.
The map shows that the part of the country in exceptional or extreme drought -- dipped to 21.45 percent. That was down 1.7 percent from last week. Parts of Missouri, Illinois and Indiana received as much as 6 inches of rain, easing some of the drought conditions in those states.
