A strong storm hit greater são paulo on monday (8), toppling a tree that blocked avenida dos autonomistas in osasco and damaging structures on the usp campus. No victims were reported, but firefighters handled dozens of calls related to tree falls and floods. The civil defense issued a severe alert due to an extratropical cyclone.
The storm that hit the paulista capital and metropolitan region in the afternoon of december 8, 2025, caused significant traffic disruptions and infrastructure damage. In osasco, a section of avenida dos autonomistas, the city's main road, was blocked after a tree fell at number 500, near the vila yara bus terminal. Buses faced delays of about one hour due to detours to access the terminal.
On the usp campus in west são paulo, the storm led to partial collapses and broken windows. Part of the ceiling in the fflch (faculty of philosophy, letters and human sciences) administration gave way, but no one was hit. In the fea (faculty of economics, administration, accounting and actuarial science), ceiling panels in the lobby were damaged and facade windows broken. Classes continued normally, with students advised to avoid the affected areas. No injuries occurred in any incidents.
According to the firefighters, between 11am and 5:02pm, there were 34 calls for tree falls, 15 for floods, and one for a collapse in the capital and metropolitan area. The state civil defense of são paulo issued a severe alert for strong storms, wind gusts, lightning, and possible hail across the state, influenced by the formation of an extratropical cyclone in southern brazil. The phenomenon is expected to persist until thursday (11), with risks of more tree falls, roof damages, and power outages.
The municipal center for climate emergency management (cge) placed the city on alert for flooding and hail. Authorities recommend avoiding open areas, securing loose objects, and in emergencies, calling firefighters (193) or civil defense (199).
