This map shows dekadal (10-day) precipitation estimates from the Climate Prediction Center.
Precipitation, especially in warm semi-arid and desert fringe areas, is one of the factors responsible for creating the conditions which lead to the formation of sufficient surface water and moisture for mosquito breeding sites. Monitoring precipitation on short term time scales (1-2 weeks) may aid in determining the location and timing of a potential outbreak.
By placing recent precipitation in historical context, comparisons can be made to past outbreaks and useful early warning information can be developed for epidemic prone regions.
This map utilizes an epidemiological mask to isolate areas prone to new exposure of malaria. The mask allows for MEWS to be exclusively illustrated in areas where malaria is considered to be epidemic, therefore, areas where malaria transmission is considered absent or endemic are excluded. The mask is based purely on climatic constraints to malaria transmission and does not yet account for areas in the northern and southern margins of the continent where control has eliminated malaria risk.

The default map on this page shows the most recent dekadal (10-day) estimated precipitation amounts over Africa. As the user moves the cursor over the map, a tool bar will appear on top that will allow for previous dekads (1999-the most recent dekad) to be displayed.
The interface consists of a clickable map that allows users to generate customized time series graphs. When a desired location is clicked, four time series graphs are generated that provide analyses of recent precipitation with respect to that of recent seasons and the short-term multiple-year average.
