Current conditions
Maps of observed precipitation conditions, individual graphics by basin are produced from MERGE/GPM data generated by INPE/CPTEC, considering the period from de 1998 a 2025. Between June 9 to July 8, 2026, rainfall above the climatological average was recorded in the watersheds of the Aripuanã, Curuá Una, Guaporé, Juruá, Juruena, Madeira, Mamoré, Marañon, Purus, and Teles Pires rivers; rainfall below climatological norms resulted in a precipitation deficit along the main course of the Amazon River in Brazilian and Peruvian territories, the Branco, Içá, and Japurá river basins, the left- bank basins of the Amazon River in the northeast and northwest of the state of Pará, and the Napo and Negro river basins; Rainfall close to normal levels was recorded in the watersheds of the Abacaxis, Beni, Coari, Iriri, Ji-Paraná, and Jutaí rivers; the left- bank basins of the Amazon River in the northeast of the state of Amazonas; the Tapajós, Tefé, Ucayali, and Xingu rivers; and the main course of the Solimões River. The multi-model indicates, for the period from July 8 to July 14, 2026, forecast of predominantly negative precipitation anomalies concentrated in the northern part of the monitored area, over the main course of the Amazon River in Brazilian territory, the Branco, Curuá Una, Japurá, and Mamoré river basins, the left-bank basins of the Amazon River in the northeast of the state of Amazonas, and the northeast and northwest of the state of Pará, the Napo and Negro river basins; a forecast of positive precipitation anomalies over the Aripuanã, Javari, Ji-Paraná, Jutaí, and Teles Pires river basins; and rainfall close to climatological norms is forecast for the remaining river basins.
