Inadequate flight crew coordination during a descent procedure led to a B727 going through its assigned altitude. Apparently no altitude callout made. Bad WX with thunderstorms and crew distraction with approach procedures and information gathering.

Narrative:
Event happened on radar vector to mia ILS runway 9R. We were coming from holding at junur (25 min hold). WX was extensive, thunderstorms in all quadrants with extensive vectoring and deviating. We were cleared to descend from 16000 ft to 10000 ft. Captain was flying and deviating extensively. First officer was involved in ATC frequency change and localizer frequency change and identify. Flight engineer was checking alternate WX on ACARS. We descended through 10000 ft to 9400 ft before the crew realized the overshoot. I immediately returned the aircraft to 10000 ft. ATC never called or mentioned the deviation. All crew members need to pay more attention to the situation at hand, which is fly the aircraft first.

Title: INADEQUATE FLC COORD DURING A DSCNT PROC LED TO A B727 GOING THROUGH ITS ASSIGNED ALT. APPARENTLY NO ALT CALLOUT MADE. BAD WX WITH TSTMS AND CREW DISTR WITH APCH PROCS AND INFO GATHERING.
Narrative: EVENT HAPPENED ON RADAR VECTOR TO MIA ILS RWY 9R. WE WERE COMING FROM HOLDING AT JUNUR (25 MIN HOLD). WX WAS EXTENSIVE, TSTMS IN ALL QUADRANTS WITH EXTENSIVE VECTORING AND DEVIATING. WE WERE CLRED TO DSND FROM 16000 FT TO 10000 FT. CAPT WAS FLYING AND DEVIATING EXTENSIVELY. FO WAS INVOLVED IN ATC FREQ CHANGE AND LOC FREQ CHANGE AND IDENT. FE WAS CHKING ALTERNATE WX ON ACARS. WE DSNDED THROUGH 10000 FT TO 9400 FT BEFORE THE CREW REALIZED THE OVERSHOOT. I IMMEDIATELY RETURNED THE ACFT TO 10000 FT. ATC NEVER CALLED OR MENTIONED THE DEV. ALL CREW MEMBERS NEED TO PAY MORE ATTN TO THE SIT AT HAND, WHICH IS FLY THE ACFT FIRST.
