More than 8000 families have so far been affected by the floods in Mororo, Madogo and Anole villages in Bura Constituency of Tana River County.
According to County Red Cross coordinator Gerald Bombe, the number of the victims is expected to rise to 15000 after the metrological department announced that the current rains will continue until early weeks of May.
Bombe said the most affected areas included Boka with 300 families, Asako with 350, Koromanatha villages where houses were swept away.
Mulanjo, Adama and Madogo where 300 families were affected with Anole A and B captured 110 families while Mororo recorded the highest number of 2500 families.
The coordinator said already reports were coming from areas such as mnazini in Garsen constituency where farms have been flooded and official number of those who have since lost their lives in the county is three.
He said they have rescued at least 38 people using motor boat who were marooned by water in Bura and Nanighi.
Due to the state of the roads, Bombe said it is almost impossible to reach out to those in the interior parts of the county but Red Cross was working closely with the county government to get a quick solution to the crisis.
Area MP Ali Wario who visited the displaced families appealed to the aid agencies to move with speed and assist the affected with the humanitarian support like water proof tents and drugs.
He said the victims were at risk of contracting waterborne diseases due to poor sanitation in the makeshift camps and called on the public health to provide necessary drugs to avoid loss of lives.
Wario said the area where the temporary camp has set up was not off the hook since only two months ago, several people were admitted after being diagnosed with cholera.
