One Good Thing About Isaac?

The one good thing about Isaac (Tropical Storm and/or Hurricane Level 1 or 2) is that it brings rain with it to some areas of drought in the South of the U.S. If it doesn't hit too hard this may bring enough rain to help crops throughout the south and up into the midwest depending upon the trajectory of the (tropical storm or hurricane) as it moves north into the Mainland.

However, the latest I heard on the Weather Channel is that they are concerned about the storm hitting New Orleans with Storm surge and this would be very problematic as well if levees come down once again in New Orleans.

One other potential positive is that all this rain may move down tributaries of the Mississippi River and lift the water level so barges can move again throughout the lower parts of the Mississippi River. So, we'll see.
