Devolution Cabinet Secretary Eugene Wamalwa told a press conference 810,665 people across the country were now affected by floods up from 808,000.
Wamalwa said that families in more than 33 counties affected will continue to receive relief food through the month of June amid projections of more rains in Western, Nyanza, Lake Basin and Coast as well as parts of Rift Valley region.
"Relief food will continue being supplied to families into June until rains stop.
After June, there will be the critical part of supporting and rehabilitating families, most of these families don't have homes and are living in tents," he said.
"We will be able to work with counties, identify families affected so that after rains stop, we will see how to restore normalcy," CS Wamalwa.
