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 2023. Between April 23 and May 22, 2024, the rainfall pattern remains below climatological levels in a large part of the monitored area, with rainfall deficits in the hydrographic basins of the Abacaxis, Aripuanã, Beni, Coari, Curuá Una, Guaporé, Iriri, Ji-Paraná, Juruá, Juruena, Jutaí, Madeira, Mamoré, Marañon, basins on the left bank of the Amazon River in the northeast of the states of Amazonas and Pará, Negro, Purus, Tapajós, Tefé, Teles Pires, Ucayali, Xingu and the main course of the Solimões River. In recent weeks, higher volumes of precipitation have been observed over the northwest of the monitored area, with the course of the Amazon in Brazilian and Peruvian territory, and the Branco, Japurá and Napo river basins characterized by positive precipitation anomalies. The basins of the Içá and Javari rivers and the basins on the left bank of the Amazon river in the northwest of the state of Pará, alternating areas with positive and negative anomalies, were considered to have observed rainfall close to the climatology for the period. The multi-seasonal forecast model indicates a predominance of rainfall below the climatology in the south of the region (basins on the right bank of the Amazon River) and a predominance of rainfall above the climatology in the north of the region over tributaries on the left bank.
