A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 05/19/2026 for the next 7 and 14 days.
The calibrated sub-seasonal multi-model forecast CPTEC/INPE-FUNCEME is generated through scientific cooperation between CPTEC/INPE and FUNCEME, and comes from a set of 4 global models (a Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP and ESRL/NOAA, the latter three from the SubX project). Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP, and ESRL/NOAA, the latter three from the SubX project). The forecast precipitation anomalies are determined in relation to the climatological period from 1999 to 2016. The outputs for the 7 and 14-day forecast intervals are shown below, detailing the forecast behavior of the basins of interest.
Forecast for the next 7 days

The figure shows the forecast for the 7-day interval between 05/20/2026 and 05/26/2026, forecast of a predominance of precipitation deficits (orange) over much of the monitored area. Forecast of positive precipitation anomalies (blue) concentrated in the northern part of the monitored region, over the Branco, Japurá, and Negro river basins and the main course of the Solimões River. Precipitation close to climatological norms (white) is forecast over the Abacaxis, Coari, Içá, and Tefé river basins.
Forecast for the next 14 days

The figure shows the prognosis for the 7-day interval between 05/27/2026 and 06/02/2026, forecast of precipitation deficit (orange) concentrated in the eastern part of the monitored region, over the basins of the Abacaxis, Aripuanã, Curuá Una, Iriri, Ji-Paraná, Marañon, Tapajós, Teles Pires, and Xingu rivers. Forecast of positive precipitation anomalies (blue) over the Coari and Tefé river basins. Rainfall close to climatological norms (white) is forecast for the remaining monitored basins.
