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 2000 a 2024. Between July 1 to July 30, 2025, below-average rainfall in the monitored area resulted in a precipitation deficit over the main course of the Amazon River in Peruvian territory, the watersheds of the Abacaxis, Aripuanã, Beni, Coari, Guaporé, Içá, Iriri, Japurá, Javari, Ji-Paraná, Juruá, Juruena, Jutaí, Madeira, Mamoré, Marañon, Napo, Negro, Purus, Tapajós, Tefé, Teles Pires, Ucayali, Xingu, and the main course of the Solimões River; rainfall above the climatological average was observed on the main course of the Amazon River in Brazilian territory, the Branco River basin and 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; rainfall close to normal in the Curuá Una River basin. The multi-model indicates for the coming weeks a predominance of rainfall above climatology concentrated in areas west of the monitored region, over the main formers of the Solimões-Amazonas system; a forecast of below-normal rainfall concentrated in the north of the region, over the Branco River basin and other basins located on the left bank of the main course of the Amazon River; and near- normal rainfall over the south of the monitored region.
