The U.S. Drought Monitor shows drought conditions across the country.

The U.S. Drought Monitor shows drought conditions across the country.

The one week change map shows areas of degradation in yellow and areas of improvement in green. Gray areas indicate where drought exists but has not changed, while white shows drought-free areas.

The one week change map shows areas of degradation in yellow and areas of improvement in green. Gray areas indicate where drought exists but has not changed, while white shows drought-free areas.

Drought expanded in the West and Southeast, but improved in the Midwest and Plains. Drought covers 60.05% of the continental US, an increase of 0.14 points. Drought has intensified in recent weeks as the spring planting season arrives.
