Could be the worst flooding on record,,,most of Calgary is now shut down..downtown is cut off by flood waters..areas outside the city esp into the foothills to the south of the city have literally been washed away whole towns evacuated and underwater..still more rain to come and rivers will continue to rise for the next 24-36 hrs...looks like the deerfoot which is the main highway north south through Calgary will be shut soon as the flood water has already closed numerous slip roads on and off and is closing in on the motorway rapidly. http://www.bbc.co.uk/news/world-us-canada-23000926
