Rio de Janeiro, which has been under alert for days, has already felt the impact of heavy rains over the past two weeks, affecting approximately 100,000 people.
Nine of the 12 months of last year had monthly temperature averages above the historical average, with September standing out with the greatest difference between the recorded value and the average.
Normally, Brazilians summers are marked by rising temperatures, longer days than nights, heavy rainfall, electrical discharges, and moderate to strong winds, but El Niño should make climate changes more intense.
States facing the heatwave should receive heavy rainfall next week. In the Southeast, the drop in temperature on Friday (Nov. 17) is likely to be accompanied by precipitation.
The institute states that the intensity of the winds should diminish from Thursday (13), as the extratropical cyclone moves towards the Atlantic Ocean and weakens.
