The maps produced used SPI values calculated from monthly rainfall totals from land stations and NCEP/NCAR reanalysis data. Only land station data is used for the eastern Caribbean, described here as from Georgetown, Guyana in the south to Anguilla in the north. The Greater (and Western) Antilles is less represented by land stations. However efforts are being made to include more land stations from that part of the region. Note that the severity implied by the index is relative to what is normal for that period of consideration. Normal in the drier season reflects less rainfall than in the wetter season.
