Hurricane Isaac helps some drought-stricken areas, leaves others behind

Even though Hurricane Isaac re-hydrated much of the very parched Midwest last weekend, meteorologists and agriculture experts say a large portion of the U.S. remains "desiccated with ponds still too shallow to water cattle, fields too dusty for feeding and crops beyond the point of salvage," John Eligon of The New York Times reports.

The drought has actually worsened in some places, shifting the greatest exceptional-drought area to the Central Plains, from South Dakota to North Texas. "Isaac's rains were like Chapter 1 in the drought relief book," said National Oceanic and Atmospheric Administration meteorologist David Miskus. "We still need a lot more rain to go here to really eliminate this drought." States including Iowa, Nebraska, Kansas, South Dakota and Oklahoma got very little rain, and conditions could get worse because of a forecast of hot temperatures this week. Miskus said many of those areas will remain in or be upgraded to extreme and exceptional drought. (U.S. Department of Agriculture Drought Monitor map, Sept. 7)

Areas from Arkansas through Missouri to Illinois saw anywhere from two to eight inches of rain, which was a welcome sign for farmers preparing to plant wheat, Eligon reports. In Illinois, 72 percent of pastures were rated in poor to very poor condition this week compared to 90 percent last week, and poor to very poor fields in Arkansas dropped 12 percentage points to 72 percent, according to the USDA.
