A line of intense thunderstorms swept across Minas Gerais on 30 September, grounding helicopters and forcing the temporary suspension of fixed-wing operations at Presidente Itamar Franco Airport (IZA/SBZM) near Juiz de Fora. The weather disruption grabbed national headlines after President Luiz Inácio Lula da Silva was unable to continue by air to a campaign event and had to return to Brasília. NOTAMs issued by the Brazilian Airspace Control Department (DECEA) indicated reduced air-traffic-service hours and the suspension of flight plan ‘AFIL’ acceptance for General Aviation, while airline crews reported go-arounds and diversions to Belo Horizonte and Rio de Janeiro. The Zona da Mata closure coincided with end-of-quarter corporate travel peaks, stranding business passengers and delaying time-critical cargo destined for the Juiz de Fora-Muriaé industrial corridor. Latam and Azul triggered irregular-operations waivers, allowing ticket changes without penalty for travel until 3 October. Ground transport was also affected as torrential rain flooded sections of the BR-267 highway linking the airport to regional production hubs. Companies with posted expatriates were advised to review emergency-contact protocols and ensure that employees use travel-tracking apps that capture real-time weather alerts. Meteorologists at INMET (Brazil’s National Institute of Meteorology) warn that a strong El Niño pattern is likely to fuel further convective systems through November, raising the prospect of additional short-notice airport closures in the Southeast. Mobility managers may wish to include Belo Horizonte-Confins or Rio Galeão as alternates for missions into Minas Gerais over the next eight weeks.
