Santa Catarina braces for heatwave after strong winds, with temperatures to exceed 30°C
Following a cold front that brought strong winds of up to 90 km/h, Santa Catarina is expected to experience stable weather and high temperatures, potentially exceeding 30°C over the weekend. The Civil Defense reported that the winds caused damage, including damaged roofs and fallen trees, particularly in Northern Santa Catarina. In Garuva, two families were displaced due to roof damage to their homes. Joinville also reported several incidents of damaged roofs and trees. Despite the damage, no injuries were reported.
Starting Friday, August 31st, sunny conditions will prevail across most of the state. Some coastal areas and the Vale do Itajaí may see light, brief rain in the early morning and evening due to oceanic humidity. Winds will be moderate in the West and South, with gusts between 40 km/h and 60 km/h, posing no significant risk of major disruptions. Morning temperatures will be cool in the highlands and Midwest regions (7°C-13°C), while other areas will range from 13°C to 17°C. Afternoon temperatures in the West could reach 30°C, with coastal areas ranging from 18°C to 27°C.
Saturday, September 1st, will begin with clear skies statewide, though isolated morning drizzles are possible in the Midwest and coastal areas. The afternoon will be warm, with temperatures in the South exceeding 33°C and reaching up to 31°C in the West. However, a new cold front approaching from Rio Grande do Sul is expected to bring scattered showers and isolated thunderstorms to the West and southern border regions by late afternoon and evening, with a low to moderate risk of damage. On Sunday, September 2nd, high humidity will maintain temperatures between 25°C and 30°C across much of the state. Rain will be concentrated in the South and near the Rio Grande do Sul border, with dry, sunny weather prevailing elsewhere.
The forecast indicates a shift from severe weather to a heatwave, a common pattern in many subtropical regions where atmospheric pressure systems rapidly change. The infrastructure damage reported from the initial high winds highlights potential vulnerabilities in building codes and maintenance practices in affected areas. As Santa Catarina anticipates rising temperatures and the return of rainfall, the focus shifts to public preparedness for heat stress and the management of potential flash floods or localized storm damage. This cyclical weather pattern underscores the importance of resilient infrastructure and adaptive urban planning to mitigate the impacts of extreme weather events, particularly in the context of evolving climate dynamics.
