Depicts large-scale trends based on subjectively derived probabilities guided by short- and
long-range statistical and dynamical forecasts. Short-term events — such as individual storms —
cannot be accurately forecast more than a few days in advance. Use caution for applications
— such as crops — that can be affected by such events. “Ongoing” drought areas are
approximated from the Drought Monitor (D1 to D4 intensity).
For weekly drought updates, see the latest U.S. Drought Monitor.
NOTE: The tan area areas imply at least a 1-category improvement in the Drought Monitor
intensity levels by the end of the period although drought w
ill remain.
The Green areas imply drought removal by the end of the period (D0 or none)
