Narrative:

Incident occurred on jun/thu/03 involving an air carrier X MD88 at san antonio airport in tx. Our call sign was flight XXXX. The flight was scheduled from jacksonville, fl, to dallas, but was subsequently diverted to san antonio due to thunderstorm in dfw. Arriving in sat, we were parked and svced on the ramp, away from the gate. With subsequent clearance to dfw, we started both engines in the chocks. As the second engine reached ground idle, I (first officer) noticed the aircraft starting to roll. I immediately hit the brakes as a power cart was positioned off the nose to the right. The stop was abrupt, but no contact was made with any ground equipment following an inspection by ground personnel. The captain's attention was diverted by ground personnel as the second engine came to idle. The chocks were in during the exterior check, but were removed sometime prior to engine start. Additionally the parking brakes were not set. In retrospect, the brakes should have been set, since we were not hooked up to a tug during start. Aircraft rolled approximately 5 ft. Deviation from the normal routine during engine start combined with fatigue from WX diversion contribute to this incident.
