Current Drought Monitor Map for Puerto Rico and the U.S. Virgin Islands
United States Drought Monitor
The Drought Monitor summary map identifies general areas of drought and labels them by intensity. D1 is the least intense level and D4 the most intense. Drought is defined as a moisture deficit bad enough to have social, environmental or economic effects.
D0 areas are not in drought, but are experiencing abnormally dry conditions that could turn into drought or are recovering from drought but are not yet back to normal.
We generally include a description on the map of what the primary physical effects are for short- and long-term drought.
- S = Drought typically less than 6 months (e.g. agriculture and grasslands)
- L = Drought typically more than 6 months (e.g. hydrology, ecology)
