A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 03/24/2026 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 above shows the forecast for the 7-day interval between 03/25/2026 and 03/31/2026, forecast of predominantly positive precipitation anomalies (blue) over the main course of the Amazon River in Peruvian territory, the basins of the Beni, Branco, Coari, Curuá Una, Içá, Japurá, Javari, Juruá, Jutaí, Madeira, Marañon, the left-bank basins of the Amazon River in the northeast of the state of Amazonas and the northwest of the state of Pará, Napo, Negro, Purus, Tefé, Ucayali, and the main course of the Solimões River. Forecast of a predominance of precipitation deficits (orange) over the Abacaxis, Teles Pires, and Xingu river basins. Rainfall forecasts close to the climatological norm (white) for the other monitored basins.
Forecast for the next 14 days
The figure above shows the prognosis for the 7-day interval between 04/01/2026 and 04/07/2026, forecast of predominantly positive precipitation anomalies (blue) over the main course of the Amazon River in Brazilian territory, the Aripuanã, Branco, and Coari river basins, the basins on the left bank of the Amazon River in the northeast of the state of Amazonas and in the northeast and northwest of the state of Pará, the Negro, Teles Pires, and Xingu rivers, and the main course of the Solimões River. Forecast of a predominance of precipitation deficits (orange) over the Mamoré and Marañon river basins. Rainfall forecasts close to the climatological norm (white) for the other monitored basins.
