The search for the missing 20-year-old NUIG student Michael Bugler continued in Galway today.
Over 300 volunteers assembled at Calasanctius College in Oranmore at 10am where they were given a briefing by gardaí.
Groups were due to search all of the shoreline between Kinvara and Carraroe.
However, heavy rainfall meant conditions were very difficult.

He is described as being 1.75m (5'9") tall, of thin build with short brown hair and blue eyes.
