A mass of air from the southwest of the country brought smoke from fires in southern Amazonas to Manaus, according to the state's Department of the Environment (Sema).
The city is facing a new wave of smoke, which intensified this Tuesday (27).
This is the second time that the "wave" of smoke has hit Manaus in August of this year, amid a serious environmental crisis caused by the fires and the critical drought affecting the state.
According to Sema, data from the National Oceanic and Atmospheric Administration (NOAA) indicate that the air mass arrived between Monday (26) and Tuesday (27) and brought with it particles from fires in southern Amazonas and neighboring states, as well as part of Bolivia.
The city government of Manaus denied that the problem originated from the fires in the city.
In a statement, the municipal administration attributed the particles to fires in other municipalities and announced the creation of a committee to combat the hot spots.
Ibama stated that the smoke is the result of fires set by cattle ranchers in the south of the state to create pasture.
Meteorologists explain that a cold front changed the circulation of the winds, which began to blow predominantly from the south to the north.
The situation should start to improve as of this Wednesday (28).
However, this does not prevent Manaus from facing new waves of smoke.
