After monitoring conditions throughout the morning, event organizers have called competition off for the Billabong Rio Pro on Wednesday due to six foot (2 meters) closeout waves at the main event site of Barra da Tijuca beach. Organizers will reconvene tomorrow morning at 7 am local time to assess conditions. [Photo/Agencies]
