Between five and ten thousand refugees migrated to Tuy Hòa. Helicopter evacuations amid the floods were primarily handled by the U.S. 119th Assault Helicopter Company. Eighteen helicopters evacuated 854 people to Cheo Reo over the course of 210 flights ahead of imminent flooding. At times, conditions during the operation forced the helicopters to turn back; the flights encountered fire from Viet Cong guerilla forces and cloud ceilings estimated at 90 m (300 ft).
