Brazil weather: Extreme cold and snow potential in south

Overview

The cold front and extratropical cyclone impacting Brazil have resulted in widespread severe weather and significant temperature shifts. Following orange-level wind alerts for eleven states, the cyclone—formed near the Brazil-Uruguay border—produced gusts up to 100 km/h, risking damage to infrastructure and agriculture. In Rio Grande do Sul, Santa Catarina, and Paraná, the system brought rain, hail, and thunderstorms, while saturated soils increased landslide and flooding risks. Severe storms driven by a line of instability previously caused widespread destruction across 117 municipalities in Rio Grande do Sul, displacing 2,686 people.

As of early September, a powerful polar air mass originating from Argentina is driving extreme cold across southern Brazil. In Santa Catarina, temperatures have dropped significantly, with some regions recording as low as -1.7 °C. Meteorologists warn of frost and the potential for localized snow or freezing rain in high-altitude areas of the Southern Plateau.

Recent reports confirm that snow and freezing rain have arrived in high-altitude areas. In Santa Catarina, temperatures reached -1.7 °C in São Joaquim and Urupema, with snow and freezing rain recorded in Bom Jardim da Serra. In Rio Grande do Sul, snowfall has been documented in the Campos de Cima da Serra region, specifically in São José dos Ausentes and Cambará do Sul. Other locations, including Gramado and São Francisco de Paula, have experienced freezing rain and graupel.

On September 6, snow was confirmed at the Monte Negro peak in São José dos Ausentes and the Fortaleza Canyon region in Cambará do Sul. São Joaquim recorded a temperature of -1.8 °C. Meteorological agencies, including INMET, Climatempo, and MetSul, continue to issue warnings for frost, low temperatures, and potential further snowfall, noting risks to public health and local agriculture.

Claims

What the coverage asserts, and how many sources carry each claim.

Coverage disagrees

Sources make claims that cannot both be true. CLSTR reports the disagreement; it does not decide who is right.

  • "INMET is monitoring a low‑pressure system that could develop into a cyclone‑bomba affecting southern Brazil, Argentina and Uruguay between 6 and 8 August."

    vs

    "The damage was caused by a cold front and heavy rains rather than the 'bomb cyclone' located near Argentina and Uruguay."

    The first claim asserts damage was caused by a cold front rather than a bomb cyclone, while the second claim discusses the monitoring of a potential bomb cyclone.

  • "The maximum temperature recorded in São Paulo was 13.6°C." www.cnnbrasil.com.br · contilnetnoticias.com.br

    vs

    "The minimum temperature recorded in São Paulo was 10.1°C." www.cnnbrasil.com.br · contilnetnoticias.com.br · ultimosegundo.ig.com.br

    These claims provide different minimum and maximum temperature values for São Paulo.
