The law for Meteorological Service Act amendment states that the date of enforcement shall be specified by a government ordinance and shall be within three months of the day on which the law is promulgated (in this case, 31 May, 2013). The formal launch date of the Emergency Warning System will be specified by a government ordinance. >> More
