Severe Winds and Heavy Rain Cause Damage Across São Paulo and Paraná

On November 7, 2026, severe weather battered São Paulo and Paraná states with intense rain and damaging winds prompting numerous alerts and response efforts. São Paulo's Civil Defense issued 72 rain alerts addressing widespread instability. A striking atmospheric micro-explosion hit Cachoeira Paulista with wind gusts reaching 126.7 km/h, damaging roofs on about 20 homes, downing trees, and causing power outages. Other parts of São Paulo such as Penápolis and Piracicaba faced strong winds topping 96 km/h leading to similar damage. Officials confirmed no injuries but warned of continued rain and winds as the state remains under an orange alert for storms.

In Paraná, Cerro Azul experienced gusts of up to 99 km/h during the storm, while over ten cities recorded gusts above 70 km/h. The violent winds brought down trees and utility poles, causing widespread power outages affecting approximately 478,500 consumers at peak. The Curitiba Civil Defense responded to over 300 requests related to fallen trees, although no families were displaced. The hardest-hit areas were the Leste and Centro-Sul regions around Curitiba. State authorities continue damage assessments and provide aid.

Meteorologist William Minhoto explained that São Paulo's micro-explosions are caused by strong descending air currents generating intense surface winds. Civil Defense teams are actively assisting affected communities with humanitarian support while urging residents to take precautions and stay indoors during the storms. The severe weather underscores the vulnerability of these regions to volatile atmospheric conditions and the importance of preparedness.
