US Drought Monitor
Current-week national drought-severity polygons (D0–D4).
What this is
The US Drought Monitor is the authoritative weekly national drought map, published every Thursday. UFFDA pulls the latest week's county-level polygons and renders them as a toggleable overlay with the official USDM color ramp. It is not public domain — the USDM permission terms require the verbatim NDMC/UNL credit string be carried with the map.
Why we surface it
Drought is the single biggest weather story in US ag most years. Ground-truth current conditions in one click, color-matched to what every USDA program report uses.
