A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 03/17/2026 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 03/18/2026 and 03/24/2026, forecast of a predominance of precipitation deficits (orange) over the main course of the Amazon River in Brazilian and Peruvian territories, and the basins of the Abacaxis, Coari, Curuá Una, Guaporé, Iça, Iriri, Japurá, Javari, Ji-Paraná, Juruena, Jutaí, Mamoré, Tapajós, Tefé, Teles Pires, and Xingu. Forecast of predominantly positive precipitation anomalies (blue) over the basins of the Beni and Branco rivers, the basins on the left bank of the Amazon River in the northwest of the state of Pará, and the Ucayali. Forecast of rainfall close to climatological norms (white) over the remaining monitored basins.
Forecast for the next 14 days

The figure above shows the prognosis for the 7-day interval between 03/25/2026 and 03/31/2026, forecast of predominantly positive precipitation anomalies (blue) in the north and northeast of the monitored region, over the main course of the Amazon River in Brazilian territory, the Abacaxis and Branco river basins, the left-bank basins of the Amazon River in the northeast of the state of Amazonas and in the northeast and northwest of the state of Pará, and the Negro River basin. No precipitation deficit (orange) is forecast for the river basins in the monitored region. Forecast of precipitation close to climatological norms (white) in the other monitored basins.
