Due to the lack of thorough communication between Area FLM's; TMU and inaccurate ESIS (display of information board); Weather re-routes of traffic re-routed to the Caribbean area were not clearly understood.  As a result; and based on inaccurate and/or misinterpreted information; a sector was prematurely combined to facilitate volume to do a Skill-Check; not knowing that a high volume of Fort Lauderdale Landing traffic was being rerouted due to severe weather towards this combined sector.  As a result of high volume; coupled with high complexity with weather reroutes; the Caribbean Sectors were put in a vulnerable situation with the last minute; unexpected traffic.  Nonetheless; the ATC teams worked through this well without incident. Lessons were learned with regard to the importance of thorough; timely and accurate coordination and status board displays.  Recommend focusing on thorough/complete and accurate communication transfer and information display.
Confused coordination/communications efforts between FLM's and the TMU and inaccurate information provided to the controllers regarding weather required re-routes in the Caribbean caused difficulty for ZMA.
