Niger: Severe weather likely to continue nationwide through at least October. Plan for possible flash flooding and travel delays.
Severe weather likely to continue across Niger through at least October. Plan for possible flash flooding and travel delays.
Event
Heavy rainfall conducive to flooding is forecast to impact Niger through October. The country has been affected by severe flooding since mid-June, which has affected most of the country's states. Maradi (southern Niger), Agadez (northern Niger) and Niamey (south-western Niger) have been particularly affected. Over Aug. 10-11, the capital Niamey recorded 144mm of rain. As of Aug. 12, at least 52 people have died and 34 others been injured nationwide. More than 4,000 residential structures have been damaged.
Hazardous Conditions
Sustained heavy rainfall could trigger further flooding. Due to the arid nature of the region and poor stormwater management in some urban areas, even minor rainfall accumulation could quickly result in episodes of flash flooding.
Transport and Utilities
Floodwaters could render some bridges, rail networks, 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.
Severe weather could also trigger flight delays and cancellations at regional airports, including - but not limited to - those serving Maradi (MFQ), Agadez (AJY), and Niamey (NIM).
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.
Disruptions to electricity and telecommunications services 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.
