The search for a 46-year-old hiker in Co Kerry was hampered by weather conditions again today with poor visibility around Cnoc Bhréanainn.
Sebastian Jaworski, 46, was last seen near the summit on Sunday 25 June and the alarm was raised when he failed to show up for work in Cork last Monday morning.
Mr Jaworski is an experienced mountaineer who knows the area well.
Speaking on RTÉ's Morning Ireland, the officer in Charge of the Daingean Uí Chúis Unit of the Irish Coast Guard, said poor visibility meant the search efforts had to be reassessed.
Frank Heidtke said there were over 50 people on the mountain yesterday, including members of the Coast Guard, gardaí, mountain rescue teams that had travelled from around the country, search dog teams and drone teams.
"Conditions were moderate yesterday up high especially, this morning now visibility is very poor and would not make any fruitful search up high, so we have to reassess.
"We have given six days searching up on the mountain, so we have to reassess today and see what the weather brings because, obviously, even for drones or aircraft to fly, you need good conditions, Mr Heidtke said.
He said Mr Jaworski was in good form and health when he was last seen, but weather conditions had deteriorated later that day.
Mr Heidtke said the mountain is a moderate hike unless you stray from the tracks and people can go astray and "finish up in territory that is very challenging".
He added that phone reception on the mountain is good but can be patchy.
Unfortunately, he said, Mr Jaworski's phone has not been used to call for help.
Search teams will be conducting targeted searches of a 20sq.km area at Cnoc Bhréanainn as conditions allow during the week.
Yesterday, Colm Burke from the Kerry Mountain Rescue Team said Mr Jaworski was last seen heading towards a feature called An Eisc, which has a descent route that would have taken him back to his vehicle, which was parked at An Fhaiche.
