Rain-swollen water levels at two Kenyan hydroelectric dams are at “historic highs” and people downstream should move away, officials have said.
Residents of flood-prone areas across the country have been ordered to evacuate or told they will be moved by force.
Kenya, along with other parts of East Africa, has been overwhelmed by flooding that killed 66 people on Monday alone and in recent days has blocked a national highway, swamped the main airport and swept a bus off a bridge.
More than 150,000 people are displaced and living in dozens of camps.
With seasonal rains forecast to increase, the Kenyan cabinet said residents of areas with flooding or landslides in the past, and residents near dams and rivers considered at high risk, will be told by Wednesday to evacuate. Those who do not will be moved by force.
It was not clear how many people will have to move, or how notifications and evacuations would be carried out on short notice, especially in crowded informal neighbourhoods.
“We will assist you all and ensure we resettle you in an area that the government has identified,” said President William Ruto during a visit to the Mai Mahiu area an hours’s drive west of Nairobi, where a river broke through a blocked tunnel on Monday and killed at least 48 people.
As bodies were pulled from under fallen trees, there was frustration with authorities.
“That tunnel started blocking on Wednesday and the local government knew about it,” said resident Sam Njoroge, who said relatives were killed.
On Kenya’s longest river, the Tana, to the east, water levels at the Masinga and Kiambere hydroelectric dams have reached historic highs, the cabinet said.
On Sunday, flooding on the Tana capsized a boat and seven people died, with another 13 reported missing. Earlier this month, high waters on the Tana swept a bus from a bridge. All 51 passengers were rescued.
Flooding in East Africa also has killed more than 150 people in neighbouring Tanzania and Somalia and affected hundreds of thousands in Ethiopia and Burundi.
