The Logone River in Chad's capital has risen to its highest level in three to four decades, media reported, citing local officials.
Above-average rainfall during the annual monsoon season has caused severe flooding across parts of West and Central Africa. Chad has been the most affected, with 1.9 million people impacted nationwide as of October 8, according to the UN humanitarian agency OCHA.
By Wednesday morning, the Logone River had reportedly risen to 8.18 meters, exceeding previous forecasts.
"This is the highest level recorded in at least 30 to 40 years," stated Sakine Youssouf, the head of the National Meteorology Agency, as quoted by the media.
On Wednesday, Prime Minister Allah Maye Halina led a meeting of the national flood management committee to formulate a response plan, noting that the floods had impacted eight of the 10 districts in N'Djamena and 17 of Chad's 23 provinces, according to reports.
