WILMINGTON, N.Y. -- Multiple police agencies are continuing to search for a missing skier on Whiteface Mountain. 

49-year-old Constantinos Filippidis, also known as "Danny," was last seen Wednesday afternoon. 

Officials say he is a firefighter from Toronto Canada, who was in the area for an annual ski trip with his colleagues. 

At the time of his disappearance, a strong snow storm was affecting visibility on the mountain.

Filippidis was last seen wearing a green ski jacket, black helmet and red skis. He's 5-foot 10-inches, 220 pounds with brown eyes and black hair.  

More than 140 people from numerous local, state and federal agencies are actively searching for Filippidis. At this time, no other volunteers are needed. 

Whiteface Mountain is still open to skiers. Anyone who sees anything out of the ordinary is asked to alert the mountain's ski patrol.
