A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 05/5/2026 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 05/06/2026 and 05/12/2026, forecast of a predominance of precipitation deficits (orange) in the monitored region, covering the basins of the Abacaxis, Aripuanã, Branco, Coari, Curuá Una, Iriri, Japurá, Ji-Paraná, Juruena, and Madeira rivers, the basins on the left bank of the Amazon River in the northeast of the state of Amazonas and the northwest of the state of Pará, and the Napo, Negro, Purus, Tapajós, Tefé, Teles Pires, and Xingu rivers. Forecast of a predominance of positive precipitation anomalies (blue) concentrated in the southwest of the monitored region, over the main course of the Amazon River in Brazilian territory, the basins of the Beni, Guaporé, Javari, Mamoré, and Marañon rivers, the basins on the left bank of the Amazon River in the northeast of the state of Pará, and the Ucayali. Predominance of 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 05/13/2026 and 05/19/2026, forecast of a predominance of positive precipitation anomalies (blue) over the main course of the Amazon River in Peruvian territory, and the basins of the Içá, Javari, Jutaí, and Napo rivers. Forecast of a predominance of precipitation deficits (orange) over the main course of the Amazon River in Brazilian territory, and the Branco, Curuá Una, Iriri, and Xingu river basins. Rainfall close to climatological norms (white) is forecast for most of the basins in the monitored region.
