Brazil’s Weather Agency Issues Multi-State Orange Alert for Severe Storms Through Friday

Forecasters attribute the risk to weakening atmospheric blocking with an approaching cold front, prompting civil‑defense plans.

Overview

  • Inmet’s danger alert is in force from 00:00 to 23:59 on Jan. 2, covering São Paulo, Rio de Janeiro and more than a dozen other states plus the Federal District.
  • Officials warn of 30–60 mm/h or 50–100 mm/day of rain, wind gusts of 60–100 km/h and possible hail, with risks of flooding, landslides, treefall and power outages.
  • São Paulo’s government activated a crisis cabinet and its Defesa Civil projects significant accumulations from Jan. 1–4, especially along the eastern portion of the state.
  • Local systems issued targeted warnings, including Cemaden‑RJ and Alerta Rio alerts to residents, with unstable conditions expected into early next week in the capital.
  • Meteorologists expect temperatures to ease over the weekend as the front organizes moisture; authorities advise safety steps and emergency contacts via 199 (Defesa Civil) and 193 (Fire Department).
