Please see the corresponding 'Discussion' item for each 'Forecast Map'. This provides a detailed explanation of the Forecast. Use the 'High Res. Map' item to download a postscript version of the Maps. Included with some of the expired forecasts are validation maps generated from data provided by NCEP/CPC.

The 'Discussion' for each region also contains maps of the rainfall cutoffs used between near-normal, above-normal, and below-normal rainfall in terms of percent normal rainfall. In addition, there are maps of the maximum and minimum extremes for rainfall in each region.

An additional global map is provided, which indicates perceived risk that the seasonal precipitation will fall into the wettest/driest 15th percentile of the observed records.

Links to previous forecast maps can be found at the bottom of this page. The climatological base period used here is 1981-2010.
