Nagasaki is located at the western part of Japan, wherein rainstorm frequently attacked this region such as Isahaya Flood in 1957 and Nagasaki Flood in 1982. In order to prevent and/or mitigate the damages of flood, early warning system using RADAR rain gauge becomes necessary. In Japan, the Foundation of River & Basin Integrated Communications abbreviated FRICS is serving information obtained by RADAR rain gauge to the several kinds of organizations. Therefore, a local government can use its information for mitigating the flood disaster through the terminals. Even though lots of local governments have been registered to FRICS, its information is not necessarily utilized effectively because its information presently does not include the predicted one. In this paper, a method for prediction of rainfall on short term basis is proposed using the information furnished by FRICS. The proposed method controlled by Fuzzy rules uses the GIS data as well as the RADAR data. The predicted rainfall of this method can be used in an urban storm drainage model such as NUMEROUS, which is available for a prediction of inundating region on a real time basis.
