CHC Early Estimates

CHC Early Estimates

Explore the table below to view the latest CHC Early Estimates for the following regions: East Africa, West Africa, Southern Africa, Central America and Caribbean, Central Asia, and Continental Africa. Variables plotted for each accumulation period (ranges from 5-days to 3 months) are early estimates of rainfall totals, difference from the 1981-2018 average (anomaly), percent of average (% average), standardized anomalies (SPI), and historical rank (1st to 3rd wettest or driest). 

Versions that only use past values are available for all five accumulation periods. The + Forecast section links to versions that show how these variables would change if the rainfall forecast at the time of map production were to materialize. Past rainfall values are based on preliminary CHIRPS data for more recent periods* and final CHIRPS data, when it is available**. These near-real-time estimates are blended with CHIRPS-GEFS forecasts for the next 15 days. The data sources and corresponding dates are documented on each map. As the Early Estimates include preliminary and forecast data, the information on these maps is subject to change.

Archived versions of these maps are availble on our FTP site, organized by region. Graphics directories contain images, and data directories contain downloadable GeoTiff data files. Archived files are automatically updated with CHIRPS Final data.

*CHIRPS preliminary is updated every five days, with a 2-day lag

**CHIRPS Final is available the 3rd week of each month
