A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 05/26/2026 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 05/27/2026 and 06/02/2026, forecast of a predominance of precipitation deficits (orange) in the southern part of the basin, over the watersheds of the Abacaxis, Aripuanã, Beni, Curuá Una, Guaporé, Iriri, Javari, Ji-Paraná, Juruá, Juruena, Madeira, Mamoré, Marañon, Purus, Tapajós, Teles Pires, Ucayali, and Xingu rivers. Forecast of positive precipitation anomalies (blue) north of the monitored region, over the main course of the Amazon River in Peruvian territory, the Branco, Içá, and Japurá river basins, the basins on the left bank of the Amazon River in the northeast and northwest of the state of Pará, the Napo, Negro, and Tefé rivers, and the main course of the Solimões River. Rainfall close to climatological norms (white) is forecast for the remaining monitored basins.
Forecast for the next 14 days
The figure shows the prognosis for the 7-day interval between 06/03/2026 and 06/09/2026, forecast of positive precipitation anomalies (blue) over the main course of the Amazon River in Peruvian territory, the Abacaxis, Beni, Coari, Içá, Japurá, Javari, Juruá, Jutaí, Madeira, and Marañon rivers; the left-bank tributary basins of the Amazon River in northeastern Pará State; the Napo, Purus, Tapajós, and Tefé rivers; and the main course of the Solimões River. Forecast of precipitation deficit (orange) along the main course of the Amazon River in Brazilian territory. Rainfall close to climatological norms (white) is forecast for the other monitored basins.
