CHC Early Estimates

The CHC Early Estimates provide a tool for monitoring rainfall conditions using combinations of CHIRPS, preliminary CHIRPS, and the CHIRPS-GEFS 15-day forecast. In October 2025, the CHC transitioned the Early Estimates from CHIRPS2 to CHIRPS3 products (e.g., CHIRPS3 Final, Prelim, and CHIRPS3-GEFS). The Recent Rainfall monitoring graphics provide moving window rainfall accumulations for the most recent 1–18 pentads (5 –180 days).
 
The +Forecast product provides an estimate of what recent totals would be if forecasted amounts materialize. More information about the CHC Early Estimates and access to the graphics and data archive can be found here. The CHC Early Estimates Regional Rainfall (this page) and the Seasonal Rainfall webpages provide easy access to regional maps.
