In the new Drought Dashboard (see Drought Indices section on the side navigation menu),
we now have high resolution drought indices that are intended to replace low resolution
maps on this page, and we will take down this page on June 1, 2021.
If data/maps you use here aren't available under the new drought indices section, please
reach out
to us with details of the data you use.
3/10/2025 alert: The weekly PDSI data files have not been updated on the source archive. We are trying to troubleshoot the problem. This page will be updated once the source data issue is resolved.
