Ethiopia: Flash flood warnings issued across southern regions through at least Nov. 4
Flash flood warnings issued across parts of southern Ethiopia through Nov. 4. Transport, business, and utility disruptions possible.
Flash flood warnings have been issued across parts of southern Ethiopia through at least Nov. 4. The Ethiopian Meteorological Institute has issued orange flash flood warnings (the second highest level on a four-tier scale) across the Afder and Liban zones in the Somali Region, Bale, East Bale, and Guji zones in the Oromia Region, and the Dawuro Zone in the Southwest Ethiopia Region Nov. 1-4 due to heavy rainfall forecast across the region.
Sustained heavy rainfall could trigger 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, especially where heavy rainfall has saturated the soil.
Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.
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 likely in areas that see heavy rainfall and potential track inundation.
Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, evacuations, and some employees' inability to reach work sites.
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 waterborne diseases. Exposure to contaminated water from inundated industrial sites, sewer systems, and septic tanks also poses a significant health threat.
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where flooding has been forecast. Do not drive on flooded roads. 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. Charge battery-powered devices in the case of prolonged electricity outages.
