Inmet Issues Multi-State Storm Warnings as São Paulo Activates Crisis Response

Overview

• Inmet posted orange alerts for severe storms in 12 states and the Federal District and broader yellow advisories elsewhere through Friday, forecasting up to 100 mm of rain per day, wind gusts of 60–100 km/h and possible hail.
• São Paulo’s civil defense activated a crisis cabinet and warned of significant rainfall totals through January 4, highlighting elevated risks of flooding, landslides, fallen trees and power outages across the metropolitan area, coast and Vale do Paraíba.
• The Southeast faces the highest storm potential as temperatures begin to ease; Rio de Janeiro remains hot with isolated downpours Friday, then turns cooler with increasing rain, and the Navy issued a weekend swell alert for the city’s coast.
• Early impacts are being logged, including 27 mm of rain and fallen trees in Ribeirão Preto overnight, while the old segment of the Tamoios highway remains closed preventively because of high landslide risk.
• Contrasting conditions persist in the Northeast, with yellow alerts for very low humidity renewed for dozens of cities in Rio Grande do Norte and Paraíba even as Bahia and Piauí receive storm warnings that include the risk of strong gusts and hail.
