Heavy rains across the country since the start of the week have caused great damage to residents in all affected areas.
A crosscheck by the Star in select city estates as well as in adjacent counties has revealed the extent to which this damage has gone.
The heavy rains affected the movement of vehicles and human traffic.
Businesses in some areas have had to stop because of the water covering the spaces within which they operate.
The Kenya Red Cross in a statement on Wednesday said the heavy rainfall received on Tuesday night has led to flash floods in various estates across the city.
The worst hit include Mukuru, Mathare, Huruma, Ruaraka, Baba Dogo, Bosnia, Umoja 3, Choka, Njiru, Ruai, Utawala, Githurai, Kahawa, Eastern Bypass, Kinoo, Kijabe, Limuru, Ruiru, Graceland, Joska, Kaswito, Kicheko, Mangili, Kenyatta Road, Juja, Kitengela, and Magadi.
According to the Red Cross, 18 people were on Wednesday morning rescued in Mradi, Mathare 4A, in Nairobi.
