A High Surf Advisory remains in place for the South Oregon Coast in an alert issued by the National Weather Service.  The advisory is dated through 4 a.m., Saturday, Dec. 15th.   NWS release – A high surf advisory is in effect until 4 AM Saturday. Large swells will create breaking waves up to 25 feet. Sneaker waves can cause sudden rushes of water over areas not previously washed by waves. Hazardous surf will cause waves to run up much higher on the beaches than normal. These powerful waves can sweep people off jetties and other exposed rocks. They can also easily move large logs and other beach debris and create a trapping or crushing hazard to anyone nearby. Bar crossings and the surf zone will be dangerous due to strong currents and breaking waves. For more information on current watches, advisories, and warnings visit weather.gov/medford.
