Abstract: Abstract Extreme weather warnings are required to reach a vast population to save many lives and protect livelihoods. However, the existing extreme weather warning systems rely on internet-based feeds, which cannot reach the wider population in developing countries especially Tanzania where many areas have limited internet connectivity. This research proposes a Common Alerting Protocol compliant extreme weather warning system for broadcasting networks in Tanzania to disseminate the extreme weather warnings messages to a broader coverage. This chapter describes the design and implementation of a proof-of-concept prototype, which managed to disseminate the extreme weather warning to a large population via mobile cellular phones and TV broadcasting stations. Group discussion observations and document analysis were employed to gather primary and secondary data to determine requirements for the extension. The effectiveness of the prototype was evaluated based on mobile phone and auto broadcasting which shows that 91.5% of SMS was successfully delivered for less than a minute and a video clip of 13.5 MB was successfully sent and interrupted in the ongoing TV session at a broadcasting station.
