INMET warning predicts high volumes in a short period and gusts of 60 to 100 km/h, with risk of floods, tree falls, and service interruptions

The INMET issued a warning for heavy rains classified as danger, valid from Thursday (2) until 11:59 PM on Saturday (4). The warning draws attention due to its scope, the high volume of precipitation in a short time, and the presence of strong winds, which requires increased attention and constant monitoring of official information.

In addition to the rain, INMET highlights that the combination with winds of 60 to 100 km/h increases the risk of damage to urban and rural infrastructure. This includes falling trees and branches, damage to the electrical grid, and interruptions of essential services, especially in areas more vulnerable to flash floods and stream overflows.

What characterizes the INMET heavy rain warning

INMET considers “heavy rains” to be events where it rains heavily in a short period, with forecasts of 30 to 60 millimeters per hour or 50 to 100 millimeters per day.

Why the warning is classified as danger

The classification of danger arises because the scenario combines a large volume of rain with strong winds. This combination usually increases the potential for material damage and risk to the population, as gusts can knock down trees, hit roofs and metal structures, and cause failures in the electrical grid.

With the soil saturated, the probability of landslides and collapses on unstable slopes also increases, affecting both urban and rural areas.

Main risks and expected impacts

The INMET alert highlights flooding on roads and riverside areas, temporary power outages, falling branches and structures, and an increased risk of electrical discharges.

The problem is not just the rain itself, but the cascading effect: accumulated water, strong winds, lightning, and saturated soil can lead to sequential disruptions, especially in places with a history of floods or geological risk areas.

How to act during the INMET warning

During the validity of the INMET warning, the recommendation is to avoid sheltering under trees and not to park vehicles near transmission towers, poles, and large signs, which may fall with gusts. It is also advised to keep a distance from windows and avoid crossing flash floods on foot or by car.

In times of strong storms, turning off electrical appliances and, if possible, the main power panel helps reduce risk of short circuits and damage to equipment. In case of emergency, the guidance is to contact Civil Defense at 199 and the Fire Department at 193.

Regions under INMET warning

The INMET informs that the warning affects hundreds of municipalities in different states, involving regions of the Midwest, Southeast, North, Northeast, and part of the South. Among the mentioned meteorological areas are Central Goiás, Triângulo Mineiro and Alto Paranaíba, Northeast Pará, Northern Pioneer Paraná, Southern Ceará, Zona da Mata, Federal District, Metropolitan São Paulo, Metropolitan Rio de Janeiro, Lower Amazon, Acre Valley, Northern Roraima, Pernambuco Sertão, and São Francisco Valley of Bahia, showing the broad reach of the instability system.

Why monitoring makes a difference

In a large country, broad alerts like this reinforce the need to follow official bulletins and local guidelines, because the intensity and risk vary from one municipality to another.

Combining information from INMET with simple prevention actions can reduce damage and avoid dangerous situations, especially where there is a history of flooding, landslides, and falling trees.

In your city, when INMET issues a danger alert, do you change your routine immediately or only worry when the rain starts to get heavy?

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Using high-resolution satellite images, archaeologists rediscovered the Egyptian city of Imet, buried for centuries in the Nile Delta, revealing rare multi-story houses, granaries, and a sacred road linked to the cobra goddess Wadjet, from about 2,400 years ago.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

Brazil delivers a giant dam worth R$ 365.7 million in Rio Grande do Sul, capable of forming an artificial lake with 138 million m³ of water, equivalent to 55,300 Olympic swimming pools and an area larger than 2,500 football fields.

African country mobilizes students, public servants, and religious communities in a giant task force, plants 350 million trees in just 12 hours, surpasses world record, and now aims for 50 billion seedlings by 2026 to restore forests that have shrunk from 35% to just 4% of the territory.

Now it’s a reality: researchers at Unicamp develop AI capable of identifying anxiety with 80% accuracy directly on a smartwatch, paving the way for continuous mental health monitoring with low energy consumption.

Fish farming becomes the new giant of Brazilian agribusiness and transforms tilapia into the “water ox,” in a chain that already moves R$ 11 billion per year and exceeds 1 million tons produced.
