Over the years, climate change has led to unpredictive patterns that are associated with extreme weather events. Consequently, in Kenya, increased precipitation has resulted in serious flash flood events. This is because short-term early warnings are not prevalent. This study therefore aims to develop a flash flood early warning system. Moreover, Vision 2030 Kenya's development blue-print, has categorically addressed the need to improve ICT to reduce the level of vulnerability in Kenya's rural counties.
