A state of local emergency has been declared in the southern Manitoba city of Morden as rising water levels forced dozens of people from their homes, the city's mayor says. Brandon Burley said so far, about 50 residences have been affected, but that number is expected to rise amid a rainfall warning in place for much of the southern half of the province. Flood crews are keeping a close eye on the area's watershed, which was already high after significant rainfall last weekend. That rain melted accumulations of snow from a storm last month.
