Narrative:

After just becoming airborne a load 'pop' was heard coming from the east/east compartment. Just after that the first officer's flight director failed and a FCC-2 fail alert was displayed as well as a stall warning fault and right aft fuel pump pressure low. Aircraft was leveled at 16;000 ft to evaluate our situation. The first officer continued to fly the aircraft and I called maintenance control and dispatch. Mutual agreement [was] made to continue to our destination for maintenance and a possible aircraft swap. Approximately five minutes after this radio call the situation rapidly deteriorated. Numerous failure alerts appeared on the status page. The status page was completely full. At this point we donned our oxygen masks and I became flying pilot. We had no idea what we had and did not have. Emergency was declared and rapid descent made. We diverted to a nearby airport where we landed without further incident. We swapped airplanes and departed with all passengers. Crew did an excellent job and CRM definitely paid off in this tasking situation.the aircraft sat in tropical rain showers all night before our departure. The first officer had to try and 'dry up' his cup holders from heavy water intrusion. Maybe we should include an inspection of the east/east compartment in preflights following heavy rain events.
