More communities in the Canadian province of Alberta have been placed on flood alert as high water levels move downstream from the city of Calgary.
About 10,000 residents in low-lying areas of the city of Medicine Hat have been ordered to leave their homes.
In Calgary, river levels have receded but the city remains under a state of emergency.
The floods, triggered by torrential rain, have killed at least three people and displaced more than 100,000 others.
