Weather
Incident occurred near end of flight as we were descending. At 11;000 FT on the arrival; the Captain and I were looking at cloud formations ahead that we thought could be rough. Radar was on but showed no returns. He made a call to the flight attendants and told them to be seated. We entered the clouds about 2 minutes later and encountered moderate turbulence. The two flight attendants in the back were hurt. One male banged his knee and required a band aid for a bloody knee. The female fell and twisted her ankle. Paramedics checked her out and she was taken to a hospital via ambulance for x-rays. The x-rays showed a small chip fracture of one of the metatarsal bones.
Two minutes after the flight crew seated the flight attendants; an A319 encountered moderate turbulence at 11;000 FT but the two aft flight attendants were injured; the most serious an ankle bone chip.
