severe to exceptional drought characterized conditions throughout
much of the Intermountain West, with the worst-affected areas in
parts of eastern Idaho, eastern Wyoming and adjacent areas of
Montana. Heavy June and July rains in much of the Southeast U.S.
alleviated incipient drought conditions in this region.
