JUDGES will have a day off when warnings of torrential rain are issued. At the moment, judges do not have to preside in court when a tropical cyclone signal number eight, nine or 10 is hoisted. When the Judicial Proceedings (Adjournment During Gale Warnings) Ordinance is amended next month, court proceedings will be automatically adjourned in case of torrential rainfall. Red rainstorm warnings are issued when 50 millimetres of rain have fallen throughout Hongkong during an hour. Children at home should not set out for school and children already at school should be sent home or kept at school. The black signal means there have been 100 millimetres or more of rain in the past two hours. A Government spokesman said: ''The judiciary is concerned about the logistical problems arising from the frequent need to transfer prisoners or other persons under detention to the courts from remote locations during heavy rainstorms. ''Accordingly, it is considered that judicial proceedings should be adjourned where there is a red or black rainstorm warning.''
