winds capable of reaching 100 kilometers per hour
No coração do noroeste goiano, o Instituto Nacional de Meteorologia emitiu um alerta laranja para quatro municípios — Mundo Novo, Nova Crixás, Novo Planalto e São Miguel do Araguaia — diante da aproximação de tempestades severas previstas entre os dias 25 e 26 de novembro de 2025. Ventos de até 100 km/h e chuvas intensas de 30 a 60 mm por hora anunciam não apenas um fenômeno climático, mas um lembrete de que a natureza, em seus momentos mais violentos, exige da sociedade tanto preparo quanto humildade. O alerta, situado no nível intermediário do sistema brasileiro de avisos meteorológicos, é a fronteira entre a prevenção e o caos — uma janela de tempo oferecida para que o imprevisível se torne, ao menos, menos devastador.
- Ventos capazes de arrancar telhados e transformar galhos em projéteis se aproximam de quatro municípios do noroeste de Goiás, colocando vidas e estruturas em risco real.
- A chuva prevista — equivalente ao peso de um balde d'água por metro quadrado a cada hora — ameaça transformar ruas em rios e áreas agrícolas em lamaçais em questão de minutos.
- Cortes de energia, queda de árvores sobre vias e edificações, danos a lavouras e risco de alagamentos compõem um cenário de ruptura simultânea em múltiplas frentes da vida cotidiana.
- O alerta foi emitido durante o dia justamente para abrir uma janela de preparação: guardar objetos soltos, carregar dispositivos, estocar água e afastar veículos de árvores ainda é possível antes da chegada da tempestade.
- As autoridades disponibilizaram canais de emergência — Defesa Civil (199), Corpo de Bombeiros (193) e CEMIG (116) — como infraestrutura formal de resposta para quando a prevenção já não for suficiente.
O Instituto Nacional de Meteorologia emitiu, na manhã do dia 25 de novembro, um alerta laranja para tempestades severas nos municípios de Mundo Novo, Nova Crixás, Novo Planalto e São Miguel do Araguaia, no noroeste de Goiás. A janela de risco se estende até as 3h do dia 26, com previsão de chuvas entre 30 e 60 mm por hora e rajadas de vento que podem atingir 100 km/h.
O alerta laranja ocupa o nível intermediário do sistema brasileiro de avisos meteorológicos — abaixo apenas do vermelho, reservado para situações de perigo extremo. Não se trata de uma precaução rotineira: ventos nessa faixa são capazes de derrubar árvores, romper fiações e converter detritos em projéteis. Chuvas nessa intensidade saturam sistemas de drenagem e transformam leitos secos em torrentes em poucos minutos.
As consequências esperadas são concretas: interrupções no fornecimento de energia elétrica, alagamentos em áreas baixas, danos a plantações e bloqueios em estradas por queda de árvores. Para os moradores das quatro cidades afetadas, o governo disponibilizou números de emergência — Defesa Civil (199), Corpo de Bombeiros (193) e a concessionária CEMIG (116) para ocorrências relacionadas à energia.
A emissão do alerta durante o horário diurno oferece uma vantagem crucial: tempo para agir antes que a tempestade chegue. Fixar objetos soltos, carregar aparelhos eletrônicos, reservar água e reposicionar veículos longe de árvores são medidas simples que podem fazer diferença significativa. O alerta não impede a tempestade — mas garante que ela não pegue ninguém completamente de surpresa.
Brazil's National Meteorology Institute issued an orange-level storm alert on November 25 for four municipalities in northwest Goiás state, warning of dangerous weather conditions expected to persist through the following morning. The alert covers Mundo Novo, Nova Crixás, Novo Planalto, and São Miguel do Araguaia, with the warning window running from 3 a.m. on November 25 through 3 a.m. on November 26.
The institute forecasts intense rainfall between 30 and 60 millimeters per hour, paired with winds capable of reaching 100 kilometers per hour. These are not minor weather fluctuations—they represent the kind of atmospheric violence that reshapes landscapes and disrupts daily life. The orange alert sits in the middle tier of Brazil's three-level warning system, below only the red alert for extreme danger but well above the yellow caution level.
The consequences of such a storm are concrete and multiple. Power lines will likely fail across the region, leaving residents without electricity for hours or longer. Agricultural areas face crop damage from the wind and waterlogging from the rain. Trees will fall—some across roads, some through structures. Flooding is a genuine risk, particularly in low-lying areas and places where drainage systems become overwhelmed by the volume of water arriving in such a compressed timeframe.
The meteorological institute's warning system exists precisely because these events carry real danger. When wind speeds approach 100 kilometers per hour, they become capable of tearing roofs from buildings, snapping branches thick as a person's torso, and turning debris into projectiles. Rainfall at 30 to 60 millimeters per hour—roughly the weight of a bucket of water falling on every square meter of ground—can transform dry riverbeds into torrents within minutes.
For residents in the four affected municipalities, the alert serves as official notice to prepare. The government has provided emergency contact numbers: the Civil Defense can be reached at 199, the Fire Department at 193, and the state utility company CEMIG at 116 for power-related emergencies. These numbers represent the formal response infrastructure, the channels through which people report missing persons, request rescue, or document damage for insurance purposes.
The timing of the alert—issued during daylight hours for a storm arriving that same evening—gives residents a window to secure loose objects, charge devices, stock water and supplies, and move vehicles away from trees. It is the kind of warning that separates preparation from chaos, though it cannot prevent the storm itself. The weather will arrive regardless. What the alert does is ensure that when it does, people are not caught entirely unprepared.

La Conversación del Hearth Otra perspectiva de la historia
Why does the institute use three separate alert levels instead of just one warning system?
Because storms aren't all equally dangerous. A yellow alert means conditions are risky but manageable—stay alert, take precautions. Orange means real hazard is coming, and you need to act now. Red is catastrophic. The three levels let people calibrate their response instead of treating every storm the same way.
Four municipalities seems like a fairly contained area. Is this a localized weather system?
Yes and no. The storm itself is moving through a specific region, but that region includes towns spread across northwest Goiás. What matters is that these four places are all in the path. A farmer in Mundo Novo and a farmer in São Miguel do Araguaia will both experience the same dangerous conditions at roughly the same time.
The rainfall rate—30 to 60 millimeters per hour—what does that actually mean for someone living there?
It means water arrives faster than the ground can absorb it or drainage systems can handle it. Streets become rivers. Basements flood. If you're in a low area, water enters your home. It's not a gentle rain; it's a deluge compressed into an hour or two.
Why does the alert specifically mention crop damage and fallen trees alongside the flooding and power cuts?
Because those are the visible, lasting consequences. Power comes back eventually. But a crop destroyed by wind and water represents months of lost work and income for a farmer. A fallen tree blocks roads, damages property, and takes days to clear. The institute lists them because they're not hypothetical—they're what actually happens when storms like this hit agricultural regions.
If someone ignores the alert, what's the worst that could happen?
They could be caught outside when winds reach 100 kilometers per hour—fast enough to knock a person down or turn debris into weapons. They could be driving when visibility drops to near zero. They could be in a structure that loses power and then floods. The alert exists because ignoring it has real consequences.
