No one wants a hurricane; where it makes landfall, the effects are devastating. We saw that last week as Isaac's winds toppled trees and powerlines leaving hundreds of thousands without power. The size of the storm pushed Gulf water well inland flooding parts of Louisiana and Mississippi. The slow-moving nature of the storm dumped over 15 inches of rain across the Mississippi Delta adding to the misery.
However, once Isaac weakened and moved inland, it did bring rain further north to drought-stricken regions of the Nation's Heartland. Too late for the corn crop in Iowa, but some states did see some relief. One way to measure this is by looking at the drought levels before and after Isaac:
While there was some improvement for Missouri, Illinois and Indiana, not much changed for Nebraska, Kansas and Oklahoma. They are too far west of the track of the storm. The first strong cold front is set to swing across the country later this week. That may be a sign of a shift in weather patterns that "could" quiet future Gulf activity.
