The town of Canmore is under a local state of emergency as heavy rainfall continues to drench the tiny mountain community.
Due to power outages and flooding, a mandatory evacuation has also been declared for the Bragg Creek area.
The rain, which has been falling steadily since Wednesday evening, has forced road closures on major highways near Canmore, Banff and Kananaskis.
People living near Cougar Creek have been evacuated, as the swelling river erodes the riverbank and inches closer to homes.
The town says on its website that power is also out across the community.

The City of Calgary has issued a state of emergency, as water levels on the Bow and Elbow Rivers climb dangerously high. The city has begun to deploy sandbags and temporary dams.
The city of Calgary has issued mandatory evacuation orders and declared a state of emergency as expected heavy rainfall and incoming high river flows become severe.
Mandatory evacuation orders have been issued for the communities of Mission, Elbow Park, Stanley Park, Roxboro, Rideau and Discovery Ridge.
Residents facing evacuation are advised to find accommodation with friends or family for a minimum of 72 hours.

I know the Alberta Emergency Management Agency is coordinating the government’s response and officials will be working around the clock to manage the situation and keep Albertans safe.
“I plan to visit the affected areas as soon as possible on Friday to see the situation first hand and to thank those who have been working so hard at keeping every one safe.”
