A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 03/3/2026 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 03/04/2026 e 03/10/2026, forecast of precipitation deficit (orange) in the north of the monitored region, over the main course of the Amazon River in Brazilian territory, the Branco, Coari, Curuá Una, Japurá, and Juruena river basins, the basins on the left bank of the Amazon River in the northeast of the state of Amazonas, and the Negro, Tefé, Teles Pires, Xingu, and main course of the Solimões River. Forecast of positive precipitation anomalies (blue) over the Abacaxis, Beni, Mamoré, Marañon, and Ucayali river basins. Forecast of rainfall close to climatology (white) over the other monitored basins
Forecast for the next 14 days
The figure shows the prognosis for the 7-day interval between 03/11/2026 e 03/17/2026, forecast of positive precipitation anomalies (blue) over the Branco, Japurá, Juruena, Marañon river basins, basins on the left bank of the Amazon River in the northeast of the state of Amazonas and in the northwest of the state of Pará, Napo, Negro, and the main course of the Solimões River. Forecast of precipitation deficit (orange) over the Curuá Una and Iriri river basins. Forecast of rainfall close to climatology (white) over the other monitored basins.
