After days of storms and violent winds – intensified by the formation of the extratropical cyclone – the sun reappears in Rio de Janeiro this Friday. In the southeast, São Paulo also benefits from mild weather, with little cloud cover, in addition to high temperatures. The maximum reaches 35°C in the capital Rio de Janeiro and 32°C in São Paulo.

— As the cyclone moves away and moves east, its intensity decreases. The winds remain strong, but there is no possibility of gusts in these regions, unlike what happened on Wednesday, — explains meteorologist Andrea Ramos.
In the southern region of the country, Paraná, Santa Catarina and Rio Grande do Sul will experience large amounts of rain. According to the red alert issued by the National Institute of Meteorology (Inmet), storms of up to 100 mm/day and winds exceeding 100 km/h hit areas like western Paraná and Santa Catarina, starting at 10 a.m.
— The situation is worrying, because there are risks of flooding, lightning and hail. This change is intensified by a trough, that is to say an elongated area of low pressure, which causes instabilities and brings very thick clouds. This condition can also favor tornadoes and micro-explosions — underlines meteorologist Cesar Soares, from Climatempo.
Storms also persist in the northern and central-western regions of the country. States like Acre and Tocantins, in addition to Mato Grosso and Goiás, experience hot and sultry weather, with precipitation up to 50 mm/day. Thermometers indicate 33°C in Cuiabá (MT), 31°C in Goiânia (GO) and Rio Branco (AC) and 30°C in Palmas (TO).
In northeastern Brazil, low relative air humidity will be present in regions such as Rio Grande do Norte, Pernambuco and Alagoas, which may cause feelings of discomfort and dryness. In Natal (RN), Recife (PE) and Maceió (AL), the maximum temperature reaches 32°C, with no risk of rain.

The recommendation of the National Institute of Meteorology (Inmet) is that the population avoids facing bad weather, observes changes in slope and, if possible, turns off electrical appliances and the general energy supply. The Institute also leaves a series of instructions for residents of areas that could be most affected by the rains. Look:
- Turn off electrical appliances and the general power supply;
- Observe changes in slope;
- Stay in a sheltered area and, in case of gusty winds, do not take shelter under trees, due to the slight risk of falling and electric shock, and do not park vehicles near transmission towers and advertising signs;
- In case of flooding or similar, protect your belongings from water by packing them in plastic bags;
- Obtain more information from Civil Protection (telephone 199) and the firefighters (telephone 193).
