Heavy rain has caused landslides in the Pokot region, 220 miles north-west of the capital Nairobi. At least 60 people are reported to have been killed.
Kenya's meteorological department issued warnings of heavy rains on 18 November, telling people in areas likely to be affected by landslides to be on "high alert".
The worst affected areas are the villages of Nyarkulian and Parua. Rescue efforts have been hampered because roads have been cut off by flooding and bridges closed after streams began overflowing.
The president of Kenya reported 'massive destruction' of property and infrastructure, and that he has ordered armed forces and rescue services to the area to help the 5,000 families that have been displaced by flash flooding.
Weather forecasts are predicting more rain which is expected to worsen flooding in low-lying areas.
