Severe Storm Threatens Minas Gerais, Brazil with Heavy Rainfall and Strong Winds
Residents across Minas Gerais, Brazil are bracing for a period of intense and potentially dangerous weather as a strong storm system moves across the region. The Instituto Nacional de Meteorologia (INMET), Brazil’s national meteorological institute, has issued alerts ranging from yellow to red for numerous municipalities, warning of torrential rainfall, strong winds, and the risk of flooding and landslides. The situation is particularly concerning for areas still recovering from recent severe weather events.
The storm, first identified on Friday, March 6th, 2026, is forecast to bring accumulations of 50 to 100 millimeters of rain, with wind gusts potentially reaching 100 km/h in some areas. The affected regions include the Mucuri Valley, Jequitinhonha Valley, and the northwest and north of Minas Gerais. Porteirinha, a municipality in the northern part of the state, is considered particularly vulnerable given its recent experience with severe storms. INMET is urging residents to exercise extreme caution and heed the advice of local authorities.
As of Saturday, March 7th, 2026, at least 112 cities are under a yellow alert, indicating a potential for rainfall between 20 and 30 millimeters per hour, with wind speeds of 40 to 60 km/h. A further 39 municipalities are under an orange alert, signifying a higher risk with the possibility of up to 100 millimeters of rain per day and stronger winds. The most critical situation is in ten cities currently under a red alert, indicating a high risk of flooding, river overflows, and landslides. The entire state of Minas Gerais is currently under some form of weather alert.
Cities at Highest Risk
The red alert, the highest level issued by INMET, signifies an exceptional meteorological event with a high probability of damage and accidents, posing a significant threat to human life and physical integrity. The following cities are currently under a red alert, facing the most immediate and severe risks:
- Espinosa
- Gameleiras
- Jaíba
- Juvenília
- Mamonas
- Manga
- Matías Cardoso
- Montalvânia
- Monte Azul
- Pai Pedro
INMET has advised the population to avoid risk areas, particularly those prone to landslides, and to stay informed through official weather channels and civil defense authorities in the Minas Gerais community. The institute emphasizes that rainfall exceeding 60 millimeters per hour or 100 millimeters per day is considered very high and capable of causing significant disruption.
Impact and Preparedness
While the forecast anticipates substantial rainfall, meteorologists currently believe the risk of the Rio Doce river overflowing is low, as there have been no significant accumulations recorded in the river’s headwaters. According to G1 Vales, the primary expected impacts include temporary flooding in streets and avenues, and difficulties with traffic during periods of intense rain. Local authorities are preparing for potential rescue operations and are urging residents to secure their homes and belongings.
The current weather situation follows a period of intense rainfall in the Zona da Mata region of Minas Gerais, which is now expected to spread to the valleys of the Rio Doce, Aço, Mucuri, and Jequitinhonha rivers. This progression of the storm system is adding to the concerns of authorities and residents alike, as many areas are still recovering from the initial impacts of the recent storms.
