The latest U.S. Drought Monitor has expanded D3 “extreme” drought across Illinois. It went from 8 percent of the state last week to 71 percent this week. This major shift was based on a number of short-term drought indicators based on rainfall, streamflow, and temperature, as well as from widespread reports of significant crop and pasture losses.
According to the USDA …
The streamlined process provides for nearly an automatic designation for any county in which drought conditions, as reported in the U.S. Drought Monitor … when any portion of a county meets the D2 (Severe Drought) drought intensity value for eight consecutive weeks. A county that has a portion of its area in a drought intensity value of D3 (Extreme Drought) or higher at any time during the growing season also would be designated as a disaster area.
Earlier this week, the USDA NASS reported that 66 percent of the corn crop, 49 percent of the soybean crop, and 91 percent of pasture was rated poor to very poor. Topsoil was rated at 91 percent poor to very poor and subsoil was rated 97 percent poor to very poor. More details can be found in the weekly Illinois Weather and Crops report.
