Due to a database error, some stations were inadvertently omitted from the PRISM monthly and daily precipitation analyses for January 1 - August 31, 2025. The September monthly update (released today) which typically provides revisions to the prior six months (March-August) was extended back to January to rectify this issue for all months affected. If you previously downloaded January and February 2025 monthly or daily precipitation grids, please re-download those grids in addition to the usual six-month update to ensure you have the corrected versions. Only precipitation was affected.
