38-year-old Roscommom Man Anthony Henehan has been missing from Galway since March 10.
Gardai, family members, and a team of volunteers are today resuming the search for him, focussing on coastal areas of Co. Galway.
Adverse weather conditions are expected, so those volunteering in the search operation are advised to wear a hi-viz jacket, wellies, waterproof clothing and carry a long stick while walking around treacherous terrain.
