Cote d'Ivoire: Severe weather likely to affect Abidjan through at least Oct. 22; flash flooding and travel delays possible

Event

Heavy rain resulting in flash flooding impacted Abidjan the morning of Oct. 22. Authorities reported that at least four people were killed in the flooding and buildings were damaged or destroyed in multiple areas of the city. Heavy rain is forecast to persist through at least Oct. 22.

Associated disruptions are almost certain, including impassable roads in affected areas.

Hazardous Conditions
Sustained heavy rainfall could trigger further flooding. Due to poor stormwater management in some areas, even minor rainfall accumulation could quickly result in episodes of flash flooding.

Transport and Utilities
Floodwaters could render some bridges or roadways impassable, impacting overland travel in the affected area. Ponding on road surfaces could cause hazardous driving conditions. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Flight delays and cancellations are also possible at Felix-Houphouet-Boigny International Airport (ABJ).

Disruptions triggered by inclement weather and resultant hazards, such as flooding, could persist well after conditions improve - it could take days for workers to clear debris after floodwaters recede. If there is severe damage to infrastructure, repair and reconstruction efforts may exacerbate any residual disruptions. Electricity and telecommunications services outages are possible where significant flooding or landslides have occurred.

Advice

Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays, as well as potential supply chain disruptions, where severe weather has been forecast. Do not drive on flooded roads. Charge battery-powered devices in case of prolonged power outages.
