The Kenya Red Cross has warned that more communities remain at risk as flooding along the Tana River continues to intensify, with rising water levels isolating villages and straining ongoing response efforts across affected counties.

In an update shared via X on Friday, May 22, 2026, the agency reported that water levels at Idsowe Bridge have risen to 5.5 metres, increasing pressure downstream and heightening concerns of further flooding in already affected areas.

“Flooding along the Tana River continues as water levels at Idsowe Bridge remain high at 5.5 metres, increasing pressure downstream,” the Kenya Red Cross stated.

Villages cut off in Tana River and Lamu

The Red Cross said several villages in Tana River County have been completely cut off by floodwaters, including Miliki, Majaliwa, and Onido in Kipini West, where residents remain stranded.

In neighbouring Lamu County, Chalaluma village has also been fully marooned, with access routes submerged and movement severely restricted.

The situation has raised fears of worsening humanitarian conditions if water levels continue to rise.

“In Tana River County (Tana Delta), Miliki, Majaliwa, and Onido villages in Kipini West are now fully cut off by floodwaters. In Lamu County, Chalaluma village is also completely marooned,” the humanitarian agency stated.

Ongoing humanitarian response

Despite the escalating crisis, the Red Cross said response operations are ongoing across affected areas.

So far, the agency has reached 2,396 households with shelter and hygiene support, while distributing 143,700 water treatment sachets to help prevent waterborne diseases in displacement areas.

In addition, support has been extended to 10 displacement camps accommodating families forced to flee rising waters.

Medical and nutrition outreaches are also being planned for hard-to-reach communities as part of expanded emergency response efforts.

“Response efforts continue, reaching 2,396 households with shelter and hygiene support, alongside distribution of 143,700 water treatment sachets and support to 10 displacement camps. Medical and nutrition outreaches are also planned for hard-to-reach areas. More communities remain at risk as river levels stay high,” the Kenya Red Cross stated.

Humanitarian officials have warned that more communities along the river basin remain vulnerable as water levels continue to stay high.

The agency cautioned that prolonged flooding could worsen access to essential services, including healthcare, clean water, and food supplies, particularly for isolated populations.

The Red Cross has also urged residents in flood-prone areas to remain vigilant and adhere to safety advisories as emergency teams continue monitoring river levels and coordinating relief efforts.

Authorities have also intensified surveillance and preparedness measures to respond to any further displacement as the flooding situation evolves.
