The incessant cases of flooding which is one of the consequences of climate change and global warming aroused our interest on the development of a local flood alarm system (LOFAS) for riverine flood forecasting. The LOFAS consists of the level sensing unit, the alarm unit and the communication unit. The level sensing unit is made-up of three level sensing probes locally designed to sense the rise in water stage of a river, the alarm unit consist of three alarms that triggers-on in response to the rise in water stage of the river and the communication unit houses the trained personnel that disseminates the water level information to the host community through bell, mobile phone or computer. It was tested to be highly sensitive with a sensitivity of about 1.01 and has a very little lag-time of about 0.19secs. If fully implemented, the LOFAS will give a real-time flood warning of riverine flooding which will encourage timely evacuation of lives and properties of people living in flood prone areas.

Keywords: Incessant, Riverine, Forecasting, Lag time, Sensitivity, Nigeria Flood.
