About this tool


1 Weeks




Trend Analysis Panel



Please note, that while we are excited to begin offering access to this new product, the full six month trend window will not be available until September 2022. Unfortunately HPRCC does not have available resources to backfill the previous six months of data required, however every Wednesday a new week of data will become available.

Water Deficit Trends is your authority for information regarding long term changes in precipitation across the country.

Here, users can analyze precipitation trends across the country. View current drought and precipitation data and trends, alongside current drought monitor information and USGS streamflows. Select any ACIS station to analyze trends across the past six months of long term data, and view the data in an exportable table, graph, or report.

* Note that enabling many layers at once may cause the interface to become slow.
