Simepar

A strong cold front advancing over Brazil's Centre-South is triggering severe storms, with up to 100 mm of rain and hail forecast across five states. An extratropical cyclone is expected to form in the South, while in Rio Grande do Sul wind and rain have caused damage and rising rivers, with civil defence reporting 83 incidents across 78 municipalities. Paraná's Simepar forecasts new storm fronts this week, and the regional electoral court is coordinating with meteorologists on weather planning for the 2026 elections. A USP model can now warn of storms up to 30 minutes ahead.
