The search for Wexford fisherman Willie Whelan, who is missing off the southeast coast, has been called off for the night.
The 41-year-old has not been seen since his trawler sank off Hook Head on Saturday night.
Navy divers arrived at Kilmore Quay this afternoon and went to the general search area off Hook Head to conduct an initial assessment.
However, adverse weather conditions prevented them from using some of the specialised navy equipment which was brought to try and confirm the location of the sunken trawler, the Alize.
The divers are using the Naval Service vessel LE Samuel Beckett as their base while in the area.
However, when an actual dive can take place will depend on the weather improving.
In the meantime they will hope to use sonar devices, automated and remotely-operated vehicles to track the location of the trawler and to examine its condition.
Lifeboats from Kilmore Quay and Dunmore East once again went out to sea to take part in the multi-agency today and returned when darkness fell.
LE Samuel Beckett has taken over command of the operation at sea, about nine nautical miles south of Hook Head.
