Water Resources Authority has asked Kenyans to be on the lookout for areas likely to be affected by the expected El Nino rains.
The El Nino rains are expected to hit various parts of the country beginning this month according to a Kenya Meteorological Department forecast.
In a notice on Wednesday, WRA said the forecast indicated that most parts of the country will experience enhanced rains that will be fairly distributed in some areas and heavily distributed in other parts.
"The heavy rainfall may lead to river levels rising significantly and may overtop the banks and cause flooding in adjacent low-lying areas such as Lower Nyando, lower Nzoia, lower Sondu, lower Gucha Migori and the shoreline streams of Lake Victoria basin; lower Perkerra, Enkare Narok river at Rumuruti, lower Tana River at Garissa, Hola and Garsen," the WRA statement reads.
According to the authority, other areas to be on the lookout for include the Laggas within the mid Tana basin( Kitui and Makueni Counties) and Ewaso Ngíro North basin ( Wajir and Mandera).
The regulator further said flash floods caused by the excessive runoff may be experienced in some areas especially urban areas such as Nairobi, Narok, Isiolo, Wajir and Mandera.
WRA said there is also a high possibility of the filling of dams with a likelihood of them spilling over and causing flooding downstream.
"The major dams in the country include Bathi, Chemeron, Chemususu, Chinga, Ellegirini, Kakuzi, Gitaru, Kamburu, Kiambere, Kindaruma, Masinga, Kiboko, Kikoneni, Kimau, Kirandich, Kiserian, Maruba, Mkurumudzi, Moiben, Mulima, Muoni, Radat, Ruiru, Sasumua, Sondu Miriu, Thiba, Ndakaini, Tindress and Turkwel dams," they said.
