A 47-year-old woman lost her life after a landslide buried her home during a severe rainstorm that struck the city of São Paulo on Wednesday afternoon (14). The downpour submerged the Vale do Anhangabaú Tunnel in the historic downtown area, causing vehicles to float and pile on top of each other. Floodwaters also poured into the Terminal Bandeira bus hub and three subway stations operated by Metrô, forcing the municipal government to suspend the city’s license-plate driving restriction during the evening rush hour.
In the northern district of Brasilândia, a hillside collapsed onto a house located on Rua Santa Cruz do Monte Castelo. Neighbors managed to pull the 47-year-old resident from the rubble before emergency crews arrived at the property. Paramedics from the Corpo de Bombeiros, the state fire department, pronounced her dead at the scene. Police officers registered the fatality at the 74th Police District (74º DP), which will lead the investigation into the collapse. Authorities had not released the victim’s identity following the initial response.
Drivers climb onto vehicle roofs to escape rising water in downtown tunnel
Downtown São Paulo recorded some of the most severe disruptions as water levels rose rapidly inside the Vale do Anhangabaú Tunnel, officially named the São João Paulo II Tunnel. The surge lifted both passenger cars and public transit buses off the pavement, trapping occupants inside 12 automobiles and two buses along the flooded underground passage. Several motorists climbed through their windows to seek refuge on the roofs of their vehicles, and firefighters carried out water rescues for four individuals. Once the water receded, the cars remained stacked atop one another in a scene resembling a historic 1999 flood in the same tunnel, when roughly 160 vehicles, including three buses, were submerged.
The municipal administration led by Mayor Ricardo Nunes of the Brazilian Democratic Movement (MDB) released an official statement attributing the flooding to the extreme concentration of rainfall. According to the mayor’s office, “it rained in just 40 minutes this Wednesday in the Anhangabaú stream basin the amount expected for 11 days in the month of October. According to data from the Climate Emergency Management Center (CGE), 42 mm of rain were recorded in that region, which represents 37% of the 112 mm forecast for the entire month across the city.”
Addressing questions about the underground drainage infrastructure, the Traffic Engineering Company (CET), the municipal agency responsible for road management, stated that “the tunnel has six pumps, which operated uninterruptedly, with no record of problems. However, the flow capacity was not sufficient given the volume of water recorded.” Beyond the downtown core, floodwaters also blocked the Ayrton Senna Tunnel and stranded drivers along Rua Amaral Gurgel and Rua General Jardim in the Consolação neighborhood.

In the southern zone of the metropolis, both the main lake and the Sapateiro Stream overflowed inside Ibirapuera Park, knocking down a perimeter fence and washing fish onto the surrounding asphalt lanes. Severe weather also affected the interior of São Paulo state, where the state Civil Defense documented street flooding in the municipality of Assis and fallen trees that partially unroofed two houses in the town of Pitangueiras.
Emergency calls, traffic congestion and rainfall totals across the metropolis
Monitoring agencies and emergency responders tracked extensive disruptions across the metropolitan area throughout the afternoon and early evening. Meteorological instruments and municipal traffic monitors recorded the following figures during the storm:
- Electrical discharges: 1,041 lightning strikes hit the city of São Paulo during the storm.
- Fire department dispatches up to 6:00 p.m.: 32 emergency calls across the capital and Greater São Paulo, comprising 17 responses for flooding, 11 for fallen trees and 4 for structural collapses.
- Tree fall incident: One of the uprooted trees crushed two parked cars on Rua Plínio Figueiredo in the Bela Vista neighborhood without causing injuries.
- Southern zone precipitation: 37 mm of accumulated rain in the Moema district, measured by the National Center for Monitoring and Early Warning of Natural Disasters (Cemaden).
- Evening rush-hour congestion: 1,017 km of slow or stopped traffic across the city around 6:30 p.m., divided into 247 km in the West Zone, 202 km in the East Zone, 167 km in the North Zone and 113 km in the downtown area.
Timeline of flood alerts and emergency responses on October 14
The storm moved rapidly across the urban basin, prompting a sequence of alerts and road closures over a four-hour window on October 14, 2026:
- 3:25 p.m. — The Climate Emergency Management Center (CGE) places the entire city of São Paulo under a state of attention for flooding.
- 3:38 p.m. — Agents from the Traffic Engineering Company (CET) begin blocking vehicle access to the Vale do Anhangabaú Tunnel.
- 3:55 p.m. — Runoff pours down the entrance stairs of the Japão-Liberdade subway station, creating a waterfall inside the passenger accessway.
- 5:34 p.m. — The state fire department logs the emergency call for the fatal residential landslide in Brasilândia.
- 7:20 p.m. — Municipal meteorologists lift the citywide state of attention while seven active flood points remain on the streets.
Transit adjustments, power outages and weather forecast for the coming days
To ease gridlock following the floods, City Hall and the CET suspended the municipal vehicle rotation system, known locally as the rodízio, for cars with license plates ending in 5 and 6 between 5:00 p.m. and 8:00 p.m. on Wednesday (14). On the underground rail network, surface runoff entered the Paraíso and Japão-Liberdade stations on Line 1-Blue, as well as the Trianon-Masp station on Line 2-Green, though trains continued operating without interruption. In a statement, the São Paulo Metrô company explained that a shallow layer of water partially affected turnstiles, information monitors and fixed staircases at the Liberdade and Paraíso entrances.
Power distribution also suffered widespread damage, leaving approximately 40,000 residential and commercial customers without electricity in the capital, according to the utility concessionaire Enel. Forecasters at the CGE expect unstable weather to persist in São Paulo on Thursday (15), with moderate to heavy rain concentrated in the afternoon and evening hours and temperatures ranging between 17°C and 25°C. On Friday (16), a cold front moving along the São Paulo state coast will keep skies overcast and trigger additional afternoon showers, with thermometers between 18°C and 23°C and renewed risks of street flooding and mudslides on waterlogged hillsides.
