The airline flight was at Flight Level 240 when the ARTCC advised the captain of possible moderate chop starting at Flight Level 220. The captain advised the flight attendants of this information. A few minutes later the flight was instructed to descend to Flight Level 190. The captain turned on the seat belt sign and requested that the passengers take their seats. During the descent the flight encountered turbulence as it entered a cloud layer at Flight Level 220. As the flight entered the cloud layer a flight attendant was dealing with a passenger who had gotten out of their seat.
