The Defesa Civil de São Paulo issued a severe weather alert for the metropolitan region of São Paulo involving heavy rains and strong winds [1].
This warning is critical for millions of residents in the capital's metropolitan area who face potential infrastructure disruptions and safety risks from rapid weather changes. The combination of high winds and lightning increases the likelihood of power outages and traffic accidents across the urban center.
The alert was issued on the afternoon of Tuesday, July 28, 2024 [2]. It remains in effect starting Wednesday, July 29, and continues through Thursday, July 30, 2024 [3].
According to the agency, the region is expecting intense rainfall, lightning, and hail [1]. The Defesa Civil said wind speeds could reach up to 90 km/h [3].
Meteorologists attribute these conditions to the arrival of a cold air mass currently forming in the region [1]. This atmospheric shift is creating the instability necessary to generate the forecasted storms and high-velocity winds.
Residents are advised to remain vigilant and follow safety protocols during the period of the alert. The agency's warnings focus heavily on the metropolitan region of the state, where high population density increases the risk of weather-related casualties and property damage [1].
“wind speeds could reach up to 90 km/h”
The convergence of a cold air mass with existing regional conditions creates a high-risk environment for urban flooding and wind damage. In a densely populated area like São Paulo, winds of 90 km/h can cause significant structural damage and disrupt public transit, necessitating a coordinated emergency response from city officials to prevent loss of life.
