São Paulo experienced rainfall on the night of February 13, shortly before the commencement of the special samba school parades at the Anhembi Sambadrome. The city reported significant traffic congestion, with 187 kilometers of delays reported by the Traffic Engineering Company (CET), which hampered attendees' arrival to this iconic cultural event. The rain resulted from a combination of warm temperatures and the intrusion of maritime breezes, as per the city's Climate Emergency Management Center (CGE). The CGE issued warnings about the potential for flooding due to the slow movement of the weather disturbances across the city, highlighting the possibility of strong wind gusts. Emergency services had already responded to multiple incidents before the parades began, including ten calls related to fallen trees and four reports of building collapses in São Paulo and the surrounding metropolitan area. One of the notable incidents occurred on Avenida Celso Garcia in the Tatuapé neighborhood. The rainfall not only disrupted traffic but raised concerns about the safety of attendees at the parade and the potential for damage in various parts of the city. As the parades are a key part of Brazilian culture and tourism, the adverse weather could deter attendance and affect the overall experience, which is watched by millions both in-person and via broadcasts.
