Newfoundland and Labrador is experiencing severe rainfall from an atmospheric river that has washed away roads in the province, including the Trans-Canada Highway.

With more rainfall expected in British Columbia and in areas of Atlantic Canada like Newfoundland, experts say the extreme weather is a glimpse into Canada's climate future.

While the efforts have been warmly welcomed by residents and local governments, one Canadian Army commander says: "If this becomes of a larger scale, more frequent basis, it will start to affect our readiness.''
