I am trying to get my head around the wx for YMIA. My reading of the TAFs is we have the TAF issued at 1758 with TEMPO 19/24 BKN 006. The next TAF issued at 2302 but not becoming valid until 0000. Please correct me if I am wrong but I think they have both diverted to YMIA (ETA YMIA before 0000) with the forecast TEMPO BKN 006?
