The Hood River County Sheriff’s Office says searchers will continue to look for a missing paddle boarder until he is found, but believe it is highly unlikely he has survived.  Andres Pombo of Florida was reported as missing on Frida afternoon, when he fell off his paddle board in Viento State Park area while practicing for a weekend race.  A kiteboarder saw Pombo fall into the water in very strong swells but quickly lost sight of him.  Several other paddle boarders were on the scene within minutes but were unable to find him.  Searchers from the Sheriff’s Office and several other regional agencies spent the weekend looking for Pombo.  Members of Pombo’s family are arriving in the area.  The Sheriff’s Office reports Pombo was not wearing a personal flotation device or a lanyard while on his paddle board.  Authorities urge everyone on the river to use a floatation device as required by law and other available safety equipment when using the river for recreation.  The Columbia River current is stronger than most people believe and strong winds increase danger when you go into the water.
