According to a weekly update at the U.S. Drought Portal (drought.gov!), "moderate" to "exceptional" drought now covers 34.3% of the contiguous United States.
The scale of drought intensity shown in these maps allows for 5 stages:
D0 - Abnormally Dry
D1 - Moderate Drought
D2 - Severe Drought
D3 - Extreme Drought
D4 - Exceptional Drought
In California, a full 36.5% of the state is now in that most severe "exceptional" drought stage for the second week in a row. These conditions are not expected to improve any time soon.
