Brazil’s National Centre for Monitoring and Alerts of Natural Disasters (CEMADEN) released a special briefing at 09:00 on 8 November warning of severe rainfall and landslide risk across São Paulo, Rio de Janeiro, Minas Gerais and Espírito Santo. The agency highlighted potential road blockages on the Anchieta – Imigrantes system, BR-116 (Dutra) and BR-381, critical arteries for freight and employee mobility.
Civil-defence units were instructed to place heavy equipment on standby and to coordinate with concessionaires for rapid debris clearance. Businesses running commuter shuttles in Greater São Paulo were advised to activate alternative routing plans, while airlines using Congonhas and Santos Dumont airports received NOTAMs about possible closure windows.

The alert follows an F3 tornado in Paraná the previous evening and underscores increasingly frequent weather-related disruptions to corporate travel in Brazil’s key economic corridor. Travel-managers should remind employees that landslide-prone stretches can reopen and close multiple times in one day; live-tracking apps and contingency hotels along the route are recommended.
CEMADEN will provide updated bulletins every six hours until the frontal system moves offshore late on 9 November.
