Brazil: Severe weather forecast in southeastern states through at least Jan. 14
Southeastern Brazil forecast to experience severe weather through at least Jan. 14. Disruptions possible.
Heavy rainfall and floods are affecting parts of southeastern Brazil as of Jan. 13. The adverse weather conditions will likely continue at least through Jan. 14.
The National Institute of Meteorology (INMET) has issued the following alerts:
Red warnings for heavy rainfall (the highest level on a three-tier scale): For parts of Espirito Santo, Minas Gerais, and Rio de Janeiro states through at least Jan. 14.
Orange warnings: For the rest of Espirito Santo, Minas Gerais, and Rio de Janeiro states, as well as for parts of Amapa, Amazonas, Maranhao, Tocantins, and Para states.
Sustained heavy rainfall could trigger further flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas. Disruptions to electricity and telecommunications services are possible where significant flooding, landslides, or strong winds impact utility networks.
Floodwaters and debris flows could render some bridges, rail networks, or roadways impassable, impacting overland travel around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation. Localized business disruptions may occur in low-lying and riverine areas.
Flooding could heighten the threat of disease outbreaks. Backflow from drains mixed with floodwaters can become trapped in open areas when inundations recede. These stagnant pools often become a breeding ground for mosquitoes and bacteria, increasing the incidence of insect- and water-borne diseases. Exposure to contaminated water from inundated industrial sites, sewer systems, and septic tanks also poses a significant health threat.
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Stay away from elevated streams, creeks, and other watercourses that are prone to flash flooding. Do not attempt to navigate flooded roadways. Exercise caution in elevated terrain due to the threat of landslides, as well as mountainous regions where avalanches pose a threat. Keep important documents and necessary medications in waterproof containers.
Observe strict food and water precautions, as municipalities could issue boil water advisories following flooding events. Take precautions against insect- and waterborne diseases in the coming days. Review contingency plans and be prepared to move quickly to shelters if evacuation orders are issued. Charge battery-powered devices in the case of prolonged electricity outages.
