DES MOINES, Iowa (AP) — The latest U.S. Drought Monitor map shows all of Iowa and most of Nebraska are suffering severe or extreme drought.

The map shows the east-central portion of the state and a section of southeast Iowa are experiencing extreme drought.

In Nebraska, the western 75 percent is enduring extreme drought, with the most of rest suffering severe drought. A few counties in central Nebraska are listed as being under exceptional drought conditions, the worst possible listing on the monitor.

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 and so doesn't include rainfall from storms Wednesday night and Thursday morning.
