Climate monitoring bodies in Santa Catarina raised the El Niño classification to 'very strong' after warming of 2.2 °C in the Pacific. The forecast indicates above-average rainfall and a greater risk of storms, hail and flooding in the state until December.

With the ground soaked by the rain, the Civil Defense of Santos intensified inspections in risk areas, carried out more than 10 inspections this week and expanded the alert system with Cell Broadcast. The Civil Defense Preventive Plan will begin on November 1st, brought forward due to the predicted impacts of El Niño.

The National Institute of Meteorology (Inmet) issued a red heat wave alert for 81 cities in eastern Minas Gerais. The warning, which indicates a great danger to health with temperatures 5°C above average, remains in force until Wednesday night (30).

Heavy rain this morning flooded streets and knocked down trees in Panambi, with a pine tree falling on a house. Despite the scare, no one was injured. The storms, which began over the weekend, left four people injured and more than 6,000 people displaced, according to Civil Defense. In Santiago, hail damaged 3,000 homes. Residents seek shelter in gyms and support centers, while Civil Defense distributes tarpaulins and renews stocks. In Lajeado, families near the Taquari River are preparing for a possible overflow.

The National Institute of Meteorology (Inmet) issued a warning for intense rains of between 20 and 30 mm/h or up to 50 mm/day, with winds of 40 to 60 km/h, in the municipalities of Lower Amazonas, such as Alenquer and Almeirim, this Tuesday (29). Despite the forecast, meteorologist Lucas Schwarcz from Ufopa states that the showers will be quick and isolated, not marking the end of the dry period, which is expected to continue due to the influence of El Niño. Dry vegetation maintains a high risk of wildfires and impairs air quality, while river levels are expected to continue to fall. Rain is seen as a punctual change, not as the end of the drought.

Intense rain hit Manaus this Monday (28), causing the roofing of houses in some neighborhoods and flooding of streets. Videos on social media show tiles ripped off by the wind. The Civil Defense of Amazonas issued a storm warning with the risk of flooding and flash floods, valid from 12:05 pm to 4:00 pm.
