Thousands of evacuees who fled from their homes as a massive wildfire ravaged the Canadian city of Fort McMurray this week were being moved again Saturday — just as the blaze was on pace to double in size within 24 hours. More than 25,000 of the 88,000 people who were forced from their neighborhoods as the flames flared uncontrollably had to be relocated, officials said. "If that fire should suddenly take a veer to the northwest, the people in those camps could be cut off and stranded," said Canadian Public Safety Minister Ralph Goodale. "If it continues to grow at present pace, it could double today," Goodale said early Saturday.
