— The stretching of a low pressure center currently located in Paraguay favors the emergence of troughs near the coastal coast, between the South and Southeast regions. These systems favor rain, which usually comes in the form of thunderstorms, says meteorologist Andrea Ramos.
According to Inmet data, storms are also expected in the north and west-central part of the country, mainly in the afternoon. The weather remains rainy and muggy in cities like Manaus (AM), Rio Branco (AC), Cuiabá (MT) and Goiânia (GO). The maximum is 33°C in the capital of Amazonas, 31°C in Acre, in addition to 34°C in the capital of Mato Grosso and 32°C in Goiás.
Unlike other regions, the weather remains stable across much of northeastern Brazil, with no rain forecast. On the first day of the year, temperatures can reach 33°C in São Luís (MA), 31°C in Recife (PE) and 30°C in Fortaleza (CE).
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).
