Armin Sayson, president of the Philippine-American Society of Greater Dayton, witnessed typhoons as a child and recalled how frightening it was to see strong winds tearing off rooftops. “I’ve not seen a disaster in the Philippines to this magnitude,” said Sayson, who resides in Fairborn. The typhoon moved across the central Philippines on Friday, leaving a path of destruction and a growing death toll. A CBS News report estimates the number of dead could reach 10,000 people.
