Based on the real-time ranking of AMeRAS (AMeDAS Ranking Service), the system automatically detects the events of heavy rains or strong winds, which are estimated to occur approximately once in two or more years, and provide them as alert information. This includes heavy snow, but we don't make a distinction between rains and snows.
