Disaster preparedness is still an evolving concept in India, though India is beset by natural and man-made disasters. Costs involved in post-disaster rehabilitation work is enormous and the governments can save some money and the population a disruption of their work and existence if there is sufficient warning before disasters. An outline of system that makes uses of new XML communication protocols, OGS-compliant FOSS GIS and WebGIS capabilities to generate early warnings that could be transmitted to 'Emergency Response Centres' (known also as 108 services in India) is presented. Such a system may be tested and could be of possible value in the absence of any such dedicated system in the state of Kerala for disaster warning. Precepts of good governance demand that technology be put to use to enhance overall well-being of the community that is being served.
