Narrative:

Declared emergency for WX deviation. Departed fll on vectors for climb out. Scattered thunderstorms over area. Needed 20 degree left turn to avoid cell. Asked mia departure for turn numerous times, no response to deviation requests. Turned to the heading to avoid the cell, declared emergency, and squawked 7700. After this, mia departure finally acknowledged. No apparent loss of separation. After deviation, returned to vectors for flight plan route. Supplemental information from acn 421223: declared emergency in order to deviation around thunderstorms. Controller would not answer repeated requests from aircraft on frequency for WX deviations. Our flight was left with no choice but to deviation to insure flight safety.
