The drought keeps getting deeper across Minnesota. New data from the US Drought Monitor released Thursday shows that 96% of the state is in a moderate to extreme drought, up from 77% a week earlier. The driest parts of the state include several counties from southwestern to south-central Minnesota. That includes most of Brown and Nicollet Counties as well as all of Blue Earth, Watonwan, Martin and Cottonwood Counties. Only two parts of the state aren’t in drought, but they’re both rated abnormally dry — Cook County at the northeastern tip of Minnesota, and a patch of Scott, Dakota, Rice and Goodhue Counties.
