Analysis narrative
The flight crew stated that the flight was on the arrival for landing. The seatbelt sign had been on and the flight attendants were making their pre-landing cabin preparations. The flight then entered a small cloud that showed no precipitation on the radar and encountered light to moderate turbulence. When the turbulence occurred one flight attendant who was standing assisting a passenger was thrown to the floor, injuring her right foot. After landing the flight attendant was given medical care and diagnosed with a broken right foot.
