(Cannon Beach, OR) -- King Tides brought huge waves to the Oregon Coast over the weekend, and they nearly cost a teenager his life. A 19-year-old went into the water at Cannon Beach just before sunset on Monday, but didn't return. A rescue swimmer paddled a surfboard into the breakers and heard a cry for help. They spotted the man and pulled him to shore. Firefighters say hypothermia could have quickly become a problem, because of the cold water temperature.
