The latest U.S. Drought Monitor map shows that severe drought affecting much of the Midwest and Great Plains now covers more than half of Iowa and three-quarters of Nebraska.
The map shows the eastern half is the driest part of Iowa, plus a bulging area in the north-central part of the state.
The map shows the rest of Iowa in a moderate drought.
The drought map is a project shared by the University of Nebraska Lincoln, the U.S. Department of Agriculture and the National Weather Service.
The latest map is based on conditions as of 6 a.m. Tuesday.
The map shows that the western 75 percent of Nebraska is suffering from a severe drought, and extreme drought is affecting some counties in the center of the state and its southwest corner.
