Widespread Storms Lash Brazil as Cyclone Is Forecast Off Southeast Coast

Overview

• Intense convective storms from 13–15 November produced hail, gusts and structural damage in São Paulo, Bahia and Minas Gerais, with municipalities reporting toppled trees, downed power poles and damaged roofs.
• National and state meteorological agencies issued yellow alerts for tens to hundreds of municipalities for 15–16 November warning of heavy rain, gusts and possible hail and advising standard safety measures such as avoiding trees and downed lines.
• Authorities reported concentrated local impacts including about 500 trees down and three injured in Santa Bárbara d’Oeste, more than 1,000 homes affected in Sete Barras, and five fallen poles in Castro Alves, with utility crews and municipal Defesa Civil teams mobilized for restorations.
• The city of São Paulo was put in a state of attention for flooding at 18:26 on Sunday after radar showed growing instabilities that could bring lightning, hail and gusts over 60 km/h.
• Forecasters say an upper‑level trough and a moisture corridor will interact with a low‑pressure system that is expected to form into a cyclone off the Southeast coast early Monday and could prolong or expand the current instability into 16 November, keeping emergency operations and alerts in place.
