The report shows all or parts of 11 counties in west-central Iowa are in their second week in the D-3 category, which means extreme drought. The scale only goes up to D-4, which is exceptional drought, though none of Iowa has reached that level yet this year.
The report shows much of Iowa’s western half remains under moderate or severe drought, while much of northern and east-central Iowa is considered abnormally dry. Only a smattering of counties on the southern and eastern borders are in normal territory.
The 11 counties now shown in extreme drought are: Adair, Audubon, Boone, Calhoun, Carroll, Cass, Crawford, Dallas, Guthrie, Sac and Shelby.
